To anyone who buys from a reseller, that person is your first point of contact for any support issues because that person got your money, not me, and the markup you paid means the seller owes you good customer service. So don't ask me for support requests unless you bought from me directly. Or check here - 2Pac Support Thread (https://bitcointalk.org/index.php?topic=1764803.0)

GekkoScience is currently working on a variety of miner projects. The biggest news is, I have access to Bitfury's new 16nm mining ASIC and will be designing a family of miners around it. I say "family" because I'm looking at a 2-chip USB stick, an 11-chip "pod" (40-100W standalone) and a 33-chip board (~220W, adjustable up or down) designed to fit on S1/3/5 heatsinks.

In order to help raise money for development on these projects, I'm working on some simpler products that follow along after the BM1384 Compac project from last year. Because BM1384 can undervolt down to about S7 stock power (0.25J/GH chip-level) and they're easy to work with, these "fundraiser" projects will keep using them. The plan is to build a 2-chip USB stick and an 8-chip "pod".

The pod miner I expect to have a 35W hashrate about 88GH, with a peak 70W hashrate of 120GH. When I have them prototyped and ready I'll have more info for you.

The USB stick, let's call it the 2Pac, will have about the same baseline hashrate and efficiency as the original Compac but per-hashrate efficiency increases quite a bit as you crank it up, and cooling should be more effective. That is to say, if all you want is a 2.5W stickminer it's no better than the original, but it's quite a bit more overclockable.

A driver with baseline functionality has already been developed, and by deployment should be both backward-compatible with the original Compac and forward-compatible with the pod.

Since this is a fundraiser for better things, I'm actually putting up 3 different ways for people to pitch in.

This is the general donation address for GekkoScience projects. Bitcoins put in here will go to prototypes, parts and the occasional hot sandwich.


12PACBUYyFhRyhRB4qB9Z5Z8M6E3p8gpmt
This is the general sales address for the 2Pac. It'll be used to buy materials to manufacture the 2Pacs, and the surplus will be funneled straight into BF16 project development. I also accept PayPal payments at sales@gekkoscience.com


12pAcLoAN9yhTbSbPwCiJFeDkw8zMAxYyH
This is a new thing I'm trying out. This is a 2Pac Loan address, and and coins here will be used for 2Pac manufacture, the profits therefrom going into BF16 development. Once the BF16 projects are rolling and turning a profit, all the coins paid into this address will be paid back to the sender's address.



MacEntyre has stock for EU sales through his website bitshopper.de
valkir is arranging a Canada group buy in an adjacent thread.
Eyeboot.com will be stocking for the Asian market, and also sells some beefy USB hubs.

2Pac sticks are $30 apiece for any quantity. For the sake of simplicity, I'll charge a flat $10 on shipping for all US orders. If you're interested in purchasing, PM me here or email sales@gekkoscience.com with quantity, shipping address and desired payment method.

Nice  I will demo them head to head against the 1 chip compac.

I still have some very good hubs.

A question  would the software that runs my 1 chips stick be plug n play with the 2 chip stick.

I use linux and novack's  cgminer from back in the day.

Canadian Group Buy approved by Sidehack.  ;D
https://bitcointalk.org/index.php?topic=1714512.0

Novak's original cgminer is only good for 1 chip. It'll drive the new stick, but you'll see a lot of HW errors - it's actually duplicate shares because both chips are hashing on the same work.

VH's code is able to dole out work to both chips, and improves the power rampup which is necessary for chips in a string. By the time they're launched, the updated code should be compatible with an arbitrary number of chips, meaning it'll work with the 1-chip Compac, the 2-chip 2Pac and the 20-chip pod.

I will be sending review units to Philipma1957 and a couple other folks. I'll make sure vh's latest functional code is available to reviewers.

There is 2 thread. 1 for the 2pac. (the one above) and 1 for the BF gear.  ;)

pod is currently mentioned as 1385 in green letters

Corrected  ;D

Happy to see you finally got around to making this buy group. I'm still scraping together funds to get a stick as shipping was just a bit more than i thought it would be, but otherwise this seems good.

The 2Pac loan description seems a little jumbled up. I don't quite understand, we're just putting our coins in there and getting the same amount back or are part of the profits put into there?

No, the 2PacLoan description is pretty accurate. The loan will be used for 2Pac [and pod] manufacturing costs; profits from 2Pac [and pod] sales will be put into BF16 project development and manufacturing; profits from BF16 project sales will repay the 2PacLoans. I would say you're contributing to BF16 project development and leave it vague, but I prefer to be clear about where people's money is actually going. People deserve transparency.

Please note that there is no mention in the 2PacLoan description about buying a 2Pac, just as there is no mention in the 1Burger donation description. This is LOANS ONLY and you WILL NOT GET A 2PAC, just YOUR MONEY PAID BACK IN TIME. Please note the thing at the end where it says "all the coins paid into this address will be paid back to the sender's address". The concept should not be difficult to grasp, and the description given is no more and no less than exactly what will happen.

I actually didn't charge shipping to people who bought before this group buy thread went live, because I hadn't come up with a plan for shipping yet.

Prior mentions of a BM1385 pod were accurate at one time. I had been working around a 10xBM1385 pod design, but ended up deciding that, since pretty much every aspect of the chip sucks more to work with, my (and VH's) time and efforts would be better served just loading up a buch of bottom-clock BM1384 and calling it good.

Glad to see you got this thread up and going. Looks like about 20 of the 1000 units are sold already.
Keep up the great work, and post pictures along the way.  ;)
Can't wait to get my 2pacs.  8)

With regards too PayPal Payments, if money is sent as a "payment to merchant" your going to have fees? Is 2.9% + $0.30 per transaction seem right?

I don't really know anymore what they charge, but 3% is what I estimate when people ask. I don't require folks to cover the fee.

Thanks, I'll chalk this one up to the T-shirt. Since I bought my 10 Compacs from CrazyGuy last time instead of directly from you.

Kk that sounds good. Maybe I was out of it yesterday but I see now. Thanks for explaining all of that to me :) I'm surprised you're allowing paypal payments with all of the charge backs that can happen, sounds good though now that I can put that money to good use.

Let's not forget the matching Canadian group buy ;)
We are people to dontcha know!

Yeah, people who haven't paid yet. Buncha freeloaders. Buncha polite and hardworking freeloaders.

So far 6 on the canadian group buy!  ;)

We're Sorry...

Will the 2pac work plugged straight into a USB2 port on a computer or would it require a separate power supply or powered USB hub?

The USB miners have the potential to draw a lot of current, especially when overclocking them, and most USB ports on a computer are limited. I have an earlier single BM1384 Compac (clocked at 325 MHz, yielding a stable 17.8± ghs) plugged into one of these:

Superbpag 7 Port Portable Multi USB Charger 70 Watt 14A with USB 3.0 Hub Data Transfer (https://www.amazon.com/Superbpag-Portable-Charger-Transfer-Samsung/dp/B013OK10YM)

But since everything I make is adjustable, it should be able to run on a standard USB port. The test setup VH uses is hooked into a computer port.

I currently have 3 of the original compacs running at 375MHz in this 10-Port 60 Watt Powered USB 3.0 Hub (https://www.amazon.com/gp/product/B01LZZD870/ref=oh_aui_detailpage_o00_s02?ie=UTF8&psc=1) which just arrived earlier today. It replaced my 7-Port Powered USB 3.0 Hub, which would start giving me the occasional error when attempting to run 3 sticks anywhere over 325 MHz. I'm wondering if I will be able to plug the 2pacs into the same hub without any problems (realizing I would likely have to run them at a lower frequency & make some voltage adjustments).

Either way, VERY happy to be getting another GekkoScience product & can't wait to start playing around with them!   ;D

that hub has a 60 watt brick so derate to 48 watts and then derate to 43 watts.

my guess is it maxes at 40-43 watt draw at the ports so 3- 4 sticks if you push 5 - 6 if you don't.

I did 80% derate for 24/7 running I did 10% derate for efficiency.  which is how I got 40-43 watts max for 24/7 running.

at 2 amps a port you are 4 maybe 5 sticks

Thanks for the info on the hub Phil (I am not much of an electrician and that is good data to have)! Do you know of any better hubs that will work with 6-10 sticks running 24/7 which are being cooled with that fan you sent me?

Also, I came across the answer to one of my own questions regarding the capability of mixing the new and old sticks in the same hub, and the good news is that you can! Don't know how I missed it but here is the quote from sidehack:

Any hub with USB and power should work. There are specialty hubs for mining designed for blocks eruptors and such available for around 150$ if you are serious about mining, but again any cheap powered hub works. Eyeboot also sells specialty hubs that run pretty well.

One of these days I'll get back around to my powered USB hub project.

Also, all orders paid as of now have been entered on the queue.

If you set the original compac at 350Mhz / 790mv, how much amperage is the sticking drawing from a port?

I would check the original compac threads for various efficiency charts posted by me and TheRealSteve.

Wow, if the unpaid are all part of the group buys and eventually go thru, that would put you at HALF the run sold already!!! Congratulations.

How do you figure that? I see 7 on the Canada group buy and like 22 paid so far, so that is only around 30?
In the OP he said he is planning on making 1000.

Maybe I am missing something?  :)

edit: Nevermind, I see what you saw now. Sorry about that.  :-[

Can you please let me know where I can find a hub like the one you described (made specifically for mining)? I have seen some of the eyeboot hubs which have a ridiculous amount of ports, but I would be interested in something like a 10-15 port hub that could handle running 6-10 sticks 24/7 at 350MHz or more. Anyway, thanks for the info and I hope you can lead me to one like you described!  ;)

Smth like this would work, although the hub only provides 12v5a and you'll need to degrade the rating. Im on a phone sadly, so this will lead to a mobile page. http://m.ebay.com/itm/261922164767?_mwBanner=1

This is cheaper and has 3.0 900ma ports, not sure of max input voltage though. http://m.ebay.com/itm/Dyconn-Power-Hub-SuperSpeed-9-Port-2-5A-Charging-Only-Industrial-Grade-USB-3-0-/112083018028?nav=SEARCH

7 port superbpag 60w, best I can recommend. https://www.amazon.com/Superbpag-Portable-Charger-Transfer-Samsung/dp/B013OK10YM

At such a low number of ports there's really nobody making hubs just for mining as most all hubs work. Mining hubs are really made for people who are serious about their sticks :)

I have this USB hub and it's solidly built and my lone Compac is happily hashing away in it. I had another 60watt hub and it wasn't very good. The Compac hashed, but was constantly having issues. It may not have been the hub, but rather the power supply provided with the hub. That power supply was always overly warm to the touch.

Yeah, the power supply that comes with most units like that are usually cheap and don't work well. I tend to replace them as soon as I get them, they're usually not of the best quality and can break on you at any moment.

Over 1/3 of the 2pacs have already been sold, great to see the amount of interest in the community for this miner. I'm personally saving for the BF16 pod and chip, but I'll see if I can buy a few more :)

Due to the Christmas, my availability will be sketchy the next couple days. If you want to order a 2Pac, either be prepared to wait a bit for me to get back to you.

Based on tracking, I very much expected to see the 2Pac test PCBs arrive today, but for some reason they didn't. Just as well because I ended up not having time to mess with 'em anyway, but it would have been nice to know they were in my custody. I'll make sure to grab 'em next week and get some assembled post-haste so I have some pictures for y'all.

Is there an Europe group by thread, have I missed seeing it?

don't think there is one quite yet. Bitshopper.de sold em last time around for EU but things are different this time around so I have no idea. Someone's going to have to make a group for EU since shipping will be real expensive to EU.

sell on ebay

and order will be like rain  8)

I would also be interested in a EU group buy thread.
If shipping costs are too high maybe we can send them all to 1 member and then he can re-send inside the EU.

From the first post of this thread:

I already agreed with sidehack to register them for EU WEEE regulations and offer them on bitshopper.de and on Amazon. It'll be available in significant numbers.

The first test PCBs were supposed to arrive Thursday before I left for holidays. I'll get them when I return this week, and have a few test units dispatched to resellers and reviewers within a few days. That's the plan anyways.

And of course there'll be pictures posted.

The excitement is building for the upcoming miner porn.  ;D

Can't wait for the upcoming pics. I love pictures of the miners more than the hashing power (dual chips? Haven't seen more than one since the hex-fury usb!) :o On the other hand, when do you expect the 1385 pod presale to start? I know it's a bit early to ask bit I'm just curious.

the answer to ^^^this is here https://bitcointalk.org/index.php?topic=1651958.msg17326499#msg17326499

On the subject of trades -

I'm comfortable with a one-to-one 2Pac trade, one S5 board for one 2Pac. Not sure yet where I'll settle for a Biggie pod (yes, the official name of the BM1384 pod is now the Biggie) but, given the estimate of $75 per versus $30 per 2Pac, 3 boards makes sense (and would probably merit free shipping). I'll probably do a trade-plus-cash where 2 boards (since they nest in pairs in their natural habitat) would cover $60 of the $75, so an additional $15 plus shipping.

But in the meantime, I'm open to trading one free 2Pac (with free economy shipping within the US) for an S5 board (that hasn't caught on fire). Anyone open to this deal?

wicked man! the Biggie is going to be so bad ass. We haven't had a decent pod miner since the U3s

i am sending one, maybe two S5 over. One would be for two 2PACs, second-not sure yet. Cannot send just boards.
My understanding is that you might keep the rest of the miner (minus two boards) to potentially mount future unannounced bitfury boards on it.
I believe that you posted somewhere that it is a possibility (with shipping of the modded miner back).

BTW, since I was talking about the future ^^^, would beaglebone blacks serve any purpose on such modded miners?

Biodom, if you send the whole miner remind me when it's time that I owe you two cores and I'll get you hooked up.

No, the Boner on those won't serve any real purpose. If it still had USB, maybe.

In the end, I am sending three full S5 over, for a couple of 2Pacs and an additional credit toward two Biggies, etc.
Details in PM.

Got a couple working 2Pacs. One small problem with the PCB (I forgot to make sure the buck enable line was tied) that's already been fixed in the design software, but everything else is working exactly as expected.

Gonna start stocking up on parts so I can assemble the other 8 prototypes and get 'em out for testing and review. Send off for PCBs first of next week and get this batch rolling.

Can't wait to get my stick and start hashing! Looks like the 2pacs are nearly identical to the original compacs, something I like with stick miners :) Can't wait to see how high these sticks can go with a powered hub...

On the original the heatsink over hung the pcb. The 2pac is level, almost like it was planned for two chips years ago  ;) :D

The overall size of the 2Pac is the same as the Compac. The heatsink is the same size, and the bottom of it is at the same height relative to the USB jack, but the PCB is extended. The ASICs are on the backside, so the heatsink is on the opposite side from the original. This heatsink is a Compac leftover re-drilled; the center screw isn't populated because the existing middle screw hole is there but about 2mm off center, making it really impossible to drill and tap a fresh M3 hole.

I had thought about a 2-chip BM1384 stick when we were doing the original Compac, but I was still thinking single-sided so it would have been shaped a lot differently. I like this one a lot better. It'll be an extra assembly step and a bit harder to do initial testing before final assembly and shipping, but the end result is quite a bit better.

Updated the order queue, assembled a full budgeted BOM, and PCBs have been ordered.

keep up the great work Sidehack. the home miner is the key to mass user adoption. hard to wax poetic about the miner you can't see / run or tinker with  8)

Thanks. Tomorrow's gonna be a busy day (sandwich day, among other errands) but maybe I'll get a head start on Biggie layout. The whole control section is already done, just gotta do the chip field and associated node signal lines and LDOs.

By the way, the next step is gathering chips so anyone who wants to trade S5 boards for credit on 2Pacs, Biggies or cores for refit boards should start talking soon.

Since it appears you have at least one 2pac running, I was wondering if the new software was available for download (whether it be a modded cgminer or a tool like zadig)?

I know you have a new software/programmer dev & remember reading he was finished for the most part with making these 2pacs or maybe it was a prototype you sold in a previous auction run better than ever? If possible, I would like to download any necessary components in preparation, & they should also work with the original compacs as well (if I am not mistaken).

Thanks sidehack!

Software will be made available when it's ready, and before 2Pacs start shipping. It's up to VH when to release, and he has a plan. He said he'd set something up before the review sticks go out so folks will be able to actually run them, and that's probably not until next week because necessary parts to build the rest of the prototype sticks are still inbound.

I'll be sending VH a care package including an original Compac, a couple 2Pacs and a decent testing hub so he can see how they behave in person and iron out any issues locally. Should speed up compatibility and stability issues.

It looks like vh has submitted something to -ck on GitHub but I haven't seen the request responded too publicly yet.


edit: push #695

That is GREAT to know! I will keep an eye out for the release, & hope it's safe to assume the download will be posted in this Thread whenever you and VH decide it's ready. Thanks again sidehack!!

Just sent the payment for my order.
Looking forward to playing with these babies in my 19 port 40 Amp USB hub.

as am I ..

I still have one of your 19 port  and one of your 48 port hubs.

I searched long and hard to find  very efficient 5 volt psus.  Which I have.

I would say we're more than 3/4 paid on the batch, but it's no longer entirely accurate. I have ordered 1000 PCBs, but MacEntyre's sticks for bitshopper.de will require a separate one-off PCB order with silkscreens to include some information he requires for European markets. He's paid up on a full 250 sticks to make this more economically feasible. Since he'll be getting custom boards anyway I'll be sending him some with sweet black soldermask to match his German-made original Compacs.

Therefore the total group buy size can exceed 1000, since I'll have about 1000 for domestic sale plus 250 for bitshopper.

Germany's official flag colors are black, red and yellow in that order, plus black is popular in clothes, so I see that.
My question is: can we here in US have something special re our colors, like red or blue.
2Pac-red or 2Pac-blue (or both), if it is doable, maybe with few extra $?
Could be quite nifty, unless it is too late (maybe sink at least?).

Last year Bitshopper licensed the Compac design for manufacture in Germany and they were made in all black, so I figured I'd get him 2Pacs to match. I don't know what motivations went into his choosing that color scheme but all in all they were quite sexy.

In general, for stuff I build, the color it is is the color it is. There is some precedence for a red Compac, maybe at least a red heatsink, but the all-green was kinda deliberate. Doesn't look like there'll be any options on the 2Pac heatsink color, just bare aluminum, unless I feel like experimenting with an anodize setup. But I'll probably be too busy.

Ah, got it, aluminum will be fine.

Agreed, Aluminum will be fine.

My opinion is to keep it simple, don't create extra work for yourself for something that will not change the functionality.

Function over Form.  :)

Couldn't agree more! With so much work ahead of GekkoScience/sidehack at this point, the last thing they need to spend time on is looking into different color options (although a US color themed stick like Biodome suggested, or even a red stick sure would make a great looking miner). Personally, if given the choice I would choose the less expensive miner if the only difference between them was color anyway.

I'm just VERY anxious for the 2pacs & looking down the road even further at the Bitfury 16nm chip. GekkoScience may have too many fun upcoming toys that I want ASAP (unfortunately I'm the impatient guy who always wants instant gratification). Looks like significant progress is being made though - nice work!

Payment sent for two..can't wait!

Would it be possible to download the VH CGMiner (or driver) at this time? After reading about all of the benefits/improvements from zadig, I would LOVE to begin using it to run my existing compacs (plus it would also be ready for when all of the new gear starts arriving)?

With all of the previous problems I faced long ago with getting CGMiner to run compacs on Windows using zadig, it would be nice to delete all of the many compilations I made in an attempt to make the original compacs work. I have been too scared when it comes to deleting the folders with what I'm pretty sure to be bad compilations (and I know I could figure it out), but since I'm not low on storage I have kept all 8-10 folders with CGMiner installations/files just to be safe..

I did look in most of your threads with recent activity for a download link, but apologize if I may have missed it. Thanks sidehack!

I agree, it would be nice to get the new miner up and running with the original compacs as soon as possible.
I'm sure when it is ready sidehack and/or vh will let everyone know.

Thanks for agreeing & the reassurance that one of them will clearly post a download link once it is 100% ready for public release. I looked around in the last several Threads sidehack was last seen in to make sure it wasn't already posted somewhere, but asked in case I had somehow missed it.

[unfortunately] I'm a Windows guy & am currently running a stripped down version of 10, & the right software/drivers for things like sidehack's compacs can make a world of difference! Wish I had the time to dedicate for learning how to fully use Linux/Ubuntu because I really can't stand Windows, but it's all I really know..

Someone provided a Windows build of cgminer-gekko back when the first Compacs rolled out. I know it worked because I bench-tested the first couple thousand sticks with it. Check the early pages of the support thread.

I also don't know how well it works on Windows 10. I don't know how well anything works on Windows 10, or if Windows 10 even works. I probably never will.

VH said he'd put up download links and a software support thread or some such by the time the proof 2Pacs have gone out to reviewers. I should have had those out already but I've been seriously backed up, but that'll probably happen by Tuesday.

That's good news.

I have the Linux build for the 1 chip stick.

The windows build worked for both 7 and 10 but as you added sticks they ran worse.
I had and still have monster usb hubs. And the issue left with the Linux build.

So I need to look for the the new build and test the 1 pac with the 2 pac.

This is GREAT news - THANK YOU!

The original build of CGMiner for windows found in the original compac thread does work on Win 10, although it acts up more often than I would like (which is why it's great to hear we will have a newer version soon). Thanks again for the update - keep chugging along doing what you're best at sidehack! Choo-Chooo..   :D


That is the problem I currently get the most frequently Phil - very erratic individual stick behavior as you begin running 2 or more. The most annoying thing is when CGMiner just decides to randomly shutdown on its own. Especially when you're away for a 2 week Holiday, & it decides to shutdown right before you board your flight after you spent a TON of time setting everything up in preparation! (true story)

I've seen this with all versions of cgminer I've used, both on Windows and RasPi. "fixed" it with a simple shell script that restarts cgminer whenever it stops...

I found a MUCH easier solution for Windows - All you need to do is add CGMiner as a Windows Service & then tell it to restart if/when it closes! Not sure what the file was that you sent me ppetrovic68 (https://bitcointalk.org/index.php?action=profile;u=179863) PmToC (https://bitcointalk.org/index.php?action=profile;u=537155), but it came up as a "backdoor" virus..

Anyone wondering how to have CGMiner automatically restart if/when it shuts down, here's how:

Run Command Prompt as administrator & type the following (quotations needed):
sc create cgminerservice binpath= "<path_to_the_executable>"

• for example: sc create cgminerservice binpath= "C:\Users\cgminer-gekko-win32\cgminer.exe"
• if done properly, you should get the result "Successful"

Now you will need to open Windows Services (one way is to click start and type services.msc)

Lastly, locate "cgminerservices", right-click, select "Properties", then click on "Recovery" tab & select "Restart the Service"

this is very useful, thanks
typically, I don't even use windows with sticks. Both raspberry pi and Linux seem to have very stable configs for mining.

I never sent any files, what are you talking about? :/

I sincerely apologize! I was referring to a member by the name of PmToC (https://bitcointalk.org/index.php?action=profile;u=537155) who sent me a PM right after my post. The PM linked to a file which comes up as a "backdoor" virus when I scanned it with Malwarebytes! I just assumed it was a "fix" for the problem I had with CGMiner shutting down as described in my post. See screenshots below:

Apology accepted :)

As for the file from the message - it seems obvious from the message text that it's a backdoor virus/miner :) Either way, good call to check it before running.

Most of the additional tools I needed to work up heatsinks have arrived. The heatsinks are only 6 fins instead of 8, but should still work well enough. I still need to build a jig for drilling, but my power tapping head arrived today so a bit more testing to dial it in and we should be in business.

I finally got around to checking out the robot program, making sure all the feeder alignments and parts rotations were correct. Tomorrow I'll have to run through it to check the actual parts placement calibrations but that takes a lot less time. Tomorrow I should get all of the prototypes built and start testing. Hopefully I'll be getting sample sticks out Friday, including one for philipma1957 to review.

I'm assuming that the PCBs will be delayed a bit, partly because they were expected to ship today but I just confirmed the panelized gerber layout yesterday so I doubt they've been made yet. Shouldn't affect much in the long run.

I still haven't gotten out BW sticks, parttly because they're entirely manual placement and that kinda sucks and partly because I've been juggling a lot of other stuff. Yesterday's workload didn't finish until 1AM. I took Sunday off instead of making progress but that's because I'd worked the previous 13 days. Anyways, once 2Pacs are rolling off the line I'll be giving a free 2Pac to the people who bought the BW sticks to help make up for the delay.

Once Chinese New Year ends and the cheap-but-easy prototype PCB house gets back to work, I should get some Biggie prototype PCBs to play with. I probably won't get around to building them until at least the middle of February because the robot and I will be quite busy with 2Pacs. There won't be a lot of retooling for parts feeders, but it will take a full day to get the placement program made and calibrated. I don't have the numbers offhand, but there are at least 40 parts per node and 5 nodes in the chip field, plus the fan control, USB interface and core power. Looking at around 250-300 components to verify placement and rotation on.

Finally got around to building a test 2Pac with good chips and ran a quick efficiency test, only up to 300MHz because my USB power meter is only rated for 3A.

Freq	GH	Vcore	Power	J/GH
100	11.00	1.26	3.67	0.33
125	13.75	1.26	4.48	0.33
150	16.50	1.26	5.27	0.32
175	19.25	1.26	6.12	0.32
200	22.00	1.32	7.43	0.34
225	24.75	1.36	8.73	0.35
250	27.50	1.40	10.11	0.37
275	30.25	1.46	12.25	0.40
300	33.00	1.50	13.98	0.42

At 300MHz, the total device efficiency is only about 15% worse than the datasheet chip-level efficiency, which I think is pretty good for a stick miner. It also puts up over 30GH, which I think is pretty darn good for a stickminer. Note this is about the same power draw the original Compac expected to see at 22GH, so we're seeing a 50% improvement in hashrate. If the stick could be pushed to 400MHz you'd see it drawing about 23W for 44GH, but I don't want to test this until I have a bit stouter measurement tool.

I'll copy this table into the OP for reference.

Hello Sidehack,

Do you have any temp reading yet ? I would be curious to know what is the chips temp at 200 and 300MHz.

Best,

No, I don't have good tools for that. What I do have is a cheap case fan capable of cooling a couple dozen sticks.

The BF16 stick will have an onboard temp sensor, but not this one.

A fairly stable version of the gekko driver I've been working on has been released in my repository for early adopters.
git clone https://github.com/vthoang/cgminer.git

The 2Pac(s) are not shipped yet, but feel free to compile it and run it against the original compac(s) if you feel brave  8).

For detailed instruction on compiling and running it, visit the new 2Pac thread here:
https://bitcointalk.org/index.php?topic=1764803.0

Thanks for the hard work and support for this project.

I have been running your cgminer 4.10.0 build with original Compac sticks for a few hours now.
Sticks are running at the clock speed of 343.75.
At this clock speed, they should reach around 18.9G. However, they average around 17.6G instead.

Just sharing what I've noticed so far.

Thanks for the feedback.    I'll check if I can replicate that this evening.   

2Pac PCBs arrived today, actually earlier than expected instead of the other thing. I got ahold of them because I was trying to order solder paste stencils as well, got that taken care of but I don't expect them before Monday. I should have time tomorrow to get the robot set up to run a full panel so Monday we can dive right in. One minion drilled out about 300 heatsinks today, and another helped me strip about 1200 chips from S5 boards, so that's pretty well on pace.

Proof 2Pacs will be sent out tomorrow, to CrazyGuy, HolyScott and MacEntyre (the big resellers) and one to philipma1957 since he offered to do a review.

I need to get the sales queue updated, since a few more orders have come in this week.

will be showing review with direct comparison to a 1 pac.

Stencils arrived this morning so we got started on surface-mounting. By tomorrow I'll have about 600 sticks with ASICs mounted, and will have started on the topside components. All heatsinks are drilled and tapped and ready to be installed. Overall, we're right on schedule.

I also happened to fetch some materials to play with anodizing a bit if I get some spare time in the next couple days.

Awesome! Keep us updated, I don't know too much about miners and how they're made but I'm always willing to learn more about em. :) Sounds like it'll be business as usual with the miners.

Awesome news, can't wait to get my hands on these.
I have everything set and running my compacs now with vh's new cgminer.  8)
I should be all set to just plug-n-play when I get them.  :D

My compac and 2pac are chugging along on mmpool.org

One is doing  11 gh
Two is doing. 22 gh

O hw in a 90 f garage.

Awesome, can't wait. Sounds like a lot of fun to design and manufacture.

You have active or passiv cooling?

He posted a picture of his setup.

https://bitcointalk.org/index.php?topic=1770235.msg17677940#msg17677940

My setup has a stud hub from klintay  that I modded with a superior psu inside it.

Mine was a usb 2.


He now sells this usb 3.0 version

http://www.ebay.com/itm/Eyeboot-19-Port-40A-USB-3-0-Hub-110-240V-2-amps-per-port-/351720554389?

I do not know if he went to the better psu inside it
but it is easy to upgrade the psu if it is like my hub.
This hub would be sweet with 16 2pacs.  I think you would not need the bridges I use since it is a usb 3.0 hub



I set volts to 5.5 on the psu.

With the bridges I can pull 1.8 amps safely  so 1.8 x 5.5 = 10 watts with ease.

Based on all the work I did with this hub a year or so back running the compacs

I can do  freq 350 non stop with the compacs and a proper fan

https://i.imgur.com/rh0WCCy.jpg

wicked pictures by the way. The USB 3.0 hub has a 40 amp psu this time so can run 18 2Pac stick miners @ 250 freq 27 GH for each stick
The other three ports are on the side so they can only fit two sticks

https://www.amazon.com/dp/B01EB33JOK
http://www.eyeboot.com/19-port-usb3

Dang that's a sexy hub. From where do you conjure up these things?

usually just from customer feedback etc. You want to see something really sexy? Remember that yellow usb hub with all the messy cables etc? We put it all into a nice neat black box:

http://www.eyeboot.com/49-port-usb-hub-version2

works a lot better now too :)

Links to USB hub charger and charging station in the description are broken.

fixed! sorry about that we are in the middle of a site upgrade.

How come the 49port hub still has the same PSU as the 19port? Could it handle a bigger PSU ?

Maybe we should start a thread about hubs so I stop getting "new post" emails that aren't about 2Pac sales?

okay will do it in hard ware>

done

Hello Sidehack,

Nice to see such progress :D !

Do you have an idea on when you should start to ship those babies ?

Best,

Patx

First orders should be going out tomorrow. These things are taking a lot longer to iron out than I expected, mostly because of issues with parts placement. I've got a minion running the pick-and-place and I think I need to give him another run-through on how to do things right. Paste isn't wetting properly so parts aren't sticking well - part of that is it's been cold lately, and part is the paste isn't being stirred right before application so it's too stiff, and part of that is I think he's just not laying it down right. Yesterday he somehow gouged the stencil so badly it took a chunk out of the PCB.

I did some figuring this morning and changed the program a bit to help out with one issue I was seeing on the board, but about two dozen sets (one "board" is 10x sticks in a panel) had already been run through so those will have to be reworked manually. And then a lot of ASICs are not stuck down right, which if I can figure up a solution for that or just do it all myself I'll end up re-doing about 20 panels but there's already 30-odd already finished I'll just have to deal with. Long story short, daily total output is half what it should be until I can solve the problems. That's a bad thing for everyone.

Good news is, the first orders should be going out tomorrow. I'll probably queue things 80/20 since that's about how the orders are lining up, which means in every 100 sticks 20 will ship for small orders and 80 for big orders.

My testing stick is running very nicely.

I boosted it to freq 225. It runs with zero issues.  Very nice stick.  Gives me about 23-24 gh

Sounds good! Can't wait to receive my one stick I ordered, if it works well I'll definitely order more as soon as I can :) having half the output of normal is still better than not having any at all. Keep us updated!

The first handful of sticks are shipping out today. I'd have more done and tested, but my minion left after 3 hours during which time he only got about 40 minutes worth of work done - 40 minutes at my pace, anyways. He's still learning the benefits of batch processes and power tools for making short work of large modularizable tasks.

I'll be queueing on an 80/20 rate, which means 80% of manufactured sticks will go to big orders and 20% to small orders. Right now that's pretty much how the breakdown is. So that means I'll ship the first 40 sticks to small orders and save the next 200 for a big order, and so on. If I can get the manufacturing pace picked up to near where I'd like it there'd be about 240 moving every week, but that's going to mean tweaking processes to get rid of the metric buttload of manual rework currently required.

I'll be working a fair bit over the weekend to get more sticks out, and ironing out some kinks with the new testing setup that's causing more issues with output. The next few orders on the list will be shipping out Tuesday.

thanks will post all stuff about usb hubs in there


wicked bro, can't wait to get my batch and start playing around with some hubs.

I came in over the weekend and got a bunch more sticks tested. Also tested out a new assembly procedure that should pick up the overall pace, which is definitely a good thing.

Anyways I have to go by the post office today anyway so I'm shipping out the next small orders. This makes the first 8 small orders, total of 47 sticks, shipped by day's end. The next 200 will be stashed for the first large order. By end of next week I should have that first large order done and be tearing into the next however many small orders. I'll have to retool for bitshopper sticks before long, so that'll slow up the domestic-order pace a bit.

Thanks for the update.
I don't know where my 6 sticks are placed in your queue but I made some silly contraption while waiting the new toys to show up.

http://imgur.com/AEiKf8S

Yours are going out today.

thanks...cute..., however, you will be cooling mostly the hub, not the sticks themselves with this setup as they will protrude much higher than the fan plane.

There is a large block of heatsink in the middle.
All the sticks will be mounted on this then connected to the hub via 6-inch Male to Female USB extension cable.
I don't know the quality of these cables so there could be some amp loss but I guess I have to play around to find out.

Thank you sir!  :D

Ah...This would work (most likely).
Cheers

This is awesome, I was thinking of doing something similar in a S3 case. I was thinking I could mount the hub and RPi right in there, that way it is just the wall plug and ethernet plug.

That is exactly the kind of thing i was thinking of doing.....until i threw my old S3 case out  ::)

Sure would be handy if we had a hub thread for this kind of thing, instead of the sales thread.

damn, forgot about this. had life going on............ its there at least 2 left? Ill pay for them right now via paypal.

Honestly I might end up having to make more of these, they're selling so fast. I gave the minion some pointers and tried a new process today that, between the two things, solve a lot of assembly problems and pretty much double the speed I can get sticks finished from the bench. If I can get it to where chips go down with near 100% reliability will be really good for Biggies. Part of the issue is paste wetting, and a lot of that is using the tail end of an old jar of paste. The new process with new paste should be pretty good.

I'm also going to dust off my beefy USB hub project. Klintay shot me some info I was having a hard time finding which should help out, and last week I came up with some ideas to simplify things while still getting the features I wanted. So that's fun. Nothing's even on paper yet, got other priorities, but it'll get there.

Glad to hear that the process is smoothing out for you.

Is the shipping order roughly the same as the order of purchases? I think I was one of the first people to send my payment and was just curious if that meant I should be expecting a package soon? No rush, just curious, and excited.  :)

Yours was the first paid order and shipped Friday.

Awesome! Now I'm excited to check the mail!  :D

Just showed up!  ;D
I'll plug them in and try them out when I get home... Well maybe I'll plug one into my office computer and play a little now.  ;)

nice  my one has been running well at freq  150  200 225 250.   I am now doing freq  200

Yummy, I will still have to wait for the EU batch.
Please do keep us posted! ;)

W00t! My 2 sticks also just came in the mail :D
Now just gotta setup a RasPi to run vh's CGminer fork for 'em and wait for my other power hub to arrive ;)

sweet please post picks  ;)

I have an idea for a bigger heatsink

I have a flat  ¼ x 8 x 8 inch plate

I think I will pull the small heat sink



attach the plate then the small heat sink  with longer screws




I will need to cut plate into this shape
the plate would sit on the hub

Received all 6 sticks in the mail.
Thank you Sidehack.

Initial setup: https://bitcointalk.org/index.php?topic=1764803.msg17873919#msg17873919

Can't wait to receive mine! Can we have the list of priority ? Just curious  :D

The first big order of 200 will be going out Monday, as well as several more small orders Monday or Tuesday. Depends on what gets done over the weekend and on Monday.

These have sold so well, and manufacture is getting smoother, that I have decided to run out a second batch. As it is, we're within about 20 of the batch cutoff anyway. This will postpone Biggie pods of course, but that's okay I was behind schedule on them anyway. Until I can work out some manufacture issues (the biggest problem I'm still having with 2Pac preparation is reliability of solder joints on ASICs; the percentage requiring rework is still too high) I won't okay that board for manufacture anyway.

Next week will start assembly of MacEntyre's bitshopper sticks. I'll get all the small orders I can out of the way with the green domestic sticks before jumping on that batch, but when it's done and shipped I'll be about halfway done with delivery. Compared to the original Compac manufacture schedule we're flat rolling. Course I have put in 70 hours in the last 6 days, but work's gotta get done. It should start getting smoother from here on out.

Sounds good! I just got my 2pac in the mail so I'll see how it works later. Will update this post as it happens.

Packed with nice paper packing and a static shielding bag, size comparison:https://s15.postimg.org/3l53zcr3v/IMG_20170217_183831.jpg

Once I find my screwdriver I'll take heatsink off and look at the chips.

FYI Monday is a national holiday so i think you mean Tuesday.....  ;)

Thanks for telling me. I usually don't find out about holidays until I go to the post office and they're closed. Well that's okay, I guess that many more orders will go out if I have an extra day to assemble and test. After the big order of 200 I'll owe about 65 sticks to the small queue before shifting to bitshoppers. At this week's pace there shouldn't be any trouble doing that if I put in at least one day this weekend.

My two sticks are probably at tail end of small orders. :-[

There's something like 60 orders after yours.

Because of the extra work required for bitshopper sticks (extra processing time because they're not panelized, stuff like that) I'm gonna ship every small order I can out of standing inventory after the next big order is met. It'll probably be close to 100 sticks instead of the 65 or so due. This'll mean about 3/4 of the small queue will have been met, and more than half the total sticks ordered (when bitshoppers ship).

I've worked out a solution to one of the more common issues (not solder or placement related) I've been seeing at the testbench, so that's good news also.

Thank you for all the updates...I can't wait!  :D

Thanks for the updates.

I'm gonna order through bitshopper when they get stock.

Yeah, thanks for the updates and everything - signed up to say that I received my 3 in the mail recently, but finally checked today and have them in hand!! Super excited to get them set up! :D

More sticks shipping out today, including Canada. There's an issue with bitshopper sticks that'll have to be addressed, so I went ahead and hit up the small order queue with green sticks to the proportion that bitshoppers had been sent out. The next batch of green sticks will be reserved for large order queue. I don't know how many yet but more will be going out Friday.

Awesome!  ;D

Got my 4 2pac's!

Forgot if I mentioned it here already, but I screwed up the bitshopper PCB order. Somehow I sent an old version of the gerber files out and left an error in 'em, so now I have a bunch of PCBs that don't work. It's a simple fix but a fix nonetheless, so we're scrapping 'em and ordering new.

I did have a bunch already made and that's how I noticed the issue.

So I've got some black 2Pacs with bitshopper silkscreens and a bit of manual jumpering I'd like to get rid of, first come first serve. PM if interested.

PMed you. Even if they're broken I'll keep em for my collection- my working gekko has been hashing away since it's got to me without any issues. All fine :)


Edit : as post below said, the miners work perfectly fine, they just have manual jumpers in them. Don't make the same mistake I made reading that post!

Just to make it clear, since I see I didn't actually say this - the bitshopper "seconds" sticks are fully functional, just they have a small wire jumper on 'em to make them work. But work they do.

^^^you'll have to look very very closely to see the hairline difference in those.

I always wanted different colors, so I am grabbing a couple before they disappear or will be sent to EU (eventually).
It is like a collection item (to me), plus i will get them earlier than EU  ;D.

TL;DR

Several sticks that sidehack is talking about are visually different (black coloring scheme) vs the rest, which are green

They also have a small jumper soldered on, like in the prototype pics (you can see it to the left of the buck chip in the bottom right corner). And yes, they're black. And darn sexy. MacEntyre has good taste.

Additionally, I have updated the sales and shipping queues. Two more large orders going out today. More chips arrived earlier than expected so bulk manufacture will resume on Monday. With any luck I'll have the next big order and several small orders out next Friday.

Bitshopper 2pac came in today, decked out fully in black except for the white heatsink and as promised I really can't tell the difference between that and my normal 2pac! I'll be posting images of the bitshopper, normal US and Canada 2pac, and compac later when I have time. Great stuff! Sidehack's delivers yet again, by buying some of them you are helping him recoup some of the cost from these slightly modified 2pacs.



Here they are! Unfortunately I have a bad phone and camera so it's not the best.
http://i66.tinypic.com/w03pyp.jpg
Besides this the two miners are the same, I do prefer the Bitshopper ones though as the black really fits the components on the back :)

Thanks, got my four sticks=2 US (green) and 2 EU style (black)

https://i.imgur.com/4SHbuDP.jpg

here is more:

front (EU stick)

Not sure if sidehack has any more more of these, though.
Did not run the sticks yet as I want to use something special with them and just came back from work.
Might do it tomorrow.

Yeah, those black sticks are darn sexy.

I have more asked for right now than I have ready to go, but I've got a box of 'em I need to either get going or strip. Honestly it's about the same amount of work either way, but selling 'em off is the way that gets paid. It's secondary to getting green sticks done and out of course, so no guarantees on time.

Looks like the Black EU ones have insufficient solder on the USB hold down tabs...Quality is everything

Seconds. Discounted. Buy one and complain if it fails or GTFO.

Am I going to have to pay a ton for BitShopper to deliver to the UK?


Doesn't look too bad, if it did end up coming loose it's a 30 second fix.

looks fine under a strong mag glass.

However, as @matt11235 said...I just remembered that i bought a soldering kit (just in case) when i first started mining.
The last time I did any soldering was with my dad when I was in K12, though, but it would be fun to re-learn it, although I am sure that it would not be necessary in this case.

Hi,

How can i buy one of these? Are they on sale yet? What is the shipping to the UK?

Thanks.

ps new user

Consider reading the first post in this thread.

Hi,

I saw his website and didnt find any 2pac on sale. and the previous version is out of stock. Im just wondering if there is any other alternatives available for me to get my hands on one of these usbs.

Thanks

Like I said, read the first post in this thread. Oddly enough it answers all your questions.

Hi,

Sorry my english is bad. Do i pay towards your address and then bitshopper.de will ship it to me?

Apologies

Oh right, UK so talking about bitshopper. He doesn't have stock yet. You might contact him directly to inquire about pricing.

Eagerly waiting for stock for the EU.
I really don't care about the color/jumpers/etc as long as I can start playing with them. :)

yeah i cannot wait to play with them. not looking for any roi as it is impossible now but just some fun

How much for a "seconds" bitshopper stick shipped to the UK? Coild it be shipped along with the BW stick from the auction?

Pics of green and Eu style (black) 2Pacs mining on Rasp Pi W:
https://bitcointalk.org/index.php?topic=1764803.msg18163917#msg18163917

I am enjoying this, thanks, sidehack and vh!

great to see a pi mining.

''I believe MacEntyre will be stocking them for EU sales through his website bitshopper.de''
Cant wait to see these appear.

Nice setup! Could you provide some details on os and others link. Thanks  ;D

sure, see link above and the followup post with more details on the 2Pac support thread.

I have updated the order queue. Right now i'm prepping for two big bulk orders. Benchwork testing is far outpacing final assembly and burn-in, but I reckon that's not necessarily a bad thing since that's where most of the problems and unknown time complexity comes in.

I'm waiting on a response back from one of the bulk purchasers who only made a down payment; if he doesn't respond soon he'll get exactly as many sticks as he's paid for and then I'll catch up on small queue. Pretty soon I'll have to jump over to Bitshopper sticks.

Speaking of, as of right now I still have three of those black sticks for sale if anyone wants one. There are two more that need more testing and then they're gone. All the pending black-stick orders will get shipped out today.

Are you talking about the ones with the jumper wire? If so how much?

Actually they just got bought up, so I'm all out.

Oh well ill have to wait for MacEntyre to get his then.

black sticks in US are collection items, perhaps,...there are probably just around 20-25 of them altogether; only sidehack knows the exact numbers. In collecting, rare items (like prints with an imperfection) have more value...eventually. I've got a couple... and they work just fine  :P

Similar thing with the original green gekkos. I only managed to get one from the US when phillipma1957 sold some of his.

Any info about to get some in Europe?

Bitshopper had no stock a few days ago and his website is down.

I'm looking for about 10 pieces, any option to get them from somewhere else?

MacEntyre hasnt had his delivery yet as far as im aware.  Website is probably down to add the info for the new stock.

There was an error with the PCB so I had to reorder, cost a few weeks. The new boards should be in this week. I'm not sure whether I'll be here next week or not, but if I am they should be pretty much done by end of next week.

The next bulk batch is shipping, and I'll be getting out most of the rest of the small-queue orders right behind it. That'll put us right about 960 or so on the current batch of green sticks, which for a batch of 1000 and considering failures and ones needing more extensive diagnosis is about right. The last few small-queue orders that came in I believe were alerted they might not get filled until the head of the second batch, which should start manufacture about April 11th.

The last green sticks are chipped and should be done with SMD population by tomorrow. I expect bitshopper PCBs to arrive any day now, but I'm not too confident since I got a tracking number 5 days ago and as of yet the shipper only acknowledges the creation of a label.

The downtime between the end of this batch (after bitshoppers) and the start of the next will be used on shop maintenance and a lot of design and prototyping.

Also, I have two more seconds black sticks available, first come first serve. They're the last of the seconds batch. All other PCBs have been stripped or slated for recycling.

Hey Phil, I need this bridge, anyway I can get them ?

no where that I know.

I have 4 or 5 of them.

Pm me your address I will toss 2 into a flat rate and ship to you.

@sidehack

the bridge  fits this hub  from klintay  I have the silver version

http://www.ebay.com/itm/Eyeboot-19-Port-40A-USB-3-0-Hub-110-240V-2-amps-per-port-/351720554389?

If I mail one to you could you build some bridges  that would fit    the 19 port  and a little smaller to fit the 49 port 


http://www.ebay.com/itm/Eyeboot-49-Port-60-Amp-USB-2-0-Hub-iphone-smartphone-charging-station-bundle-/351205671342?

Ya know, looking at that USB bridge, something to be careful of is power hubs that use multiple 5v regulators to feed the ports. eg. my Plugable 7port 60w charging hub. Uses 3 regulators; 1 for ports 1&2, 1 for ports 3&4, and 1 for ports 5-7.

Point is, unless the system is setup for it regulators do not take kindly to be connected in parallel. Just as with mixing different PSU's to feed one hash board they will fight each other...

Just make sure the big honkin' hub either uses just 1 12v-to- 5v regulator or better yet a big 5v PSU or if it uses multiple regulators. If multiple, only bridge between ports fed from the same regulator.

Along this line... @ Sidehack, ever think about putting a 3 pin power select pin header on these? Keep USB connection for the coms side but for the Vcore regulator perhaps something like left-to-center jumped for USB powered or center-to-right jumped for using external 5v (or 12v?) via a barrel connector? Solves the whole USB connection limitation I'd think.

I did order a new usb hub with more amp per port.  ;) But could be nice to get these from sidehack if possible.

BTW, as requested by Sidehack, I will create a new Canada Group Buy!  ;D

Edit: NEW GROUP BUY CANADA : https://bitcointalk.org/index.php?topic=1845225.msg18358926#msg18358926

NFW - no, I didn't ever consider that. Why I didn't ever consider that is because it becomes no longer a USB stick miner. The 2Pac is already kinda large compared to most stickminers, but once you make it bigger by adding jumpers and a barrel jack and then redo the entire buck to for 5V or 12V input you might as well just add a few more chips and call it a pod miner. I've already made a stick with outrageous overclockability, but there's no point trying to make a stick no longer a stick while still being a stick. If you want to power it with external 5V, just wire it up to external 5V. If you want to power it with external 12V it'll explode because of all the 6.3V caps and also the buck controller is specifically made for USB applications so it only works between 4 and 5.5 volts.

Well, actually I suppose I could hack into the other Plugable I have cut the traces from the regs to ports and  feed the jacks from a 5v supply..

Was pretty sure the sticks were 5v only, ergo the ? on 12v. and ja, yer right about providing a high current jack. Ja the stick would love it but rather getting carried away... ;)

If you wait just a little bit though I'll have some news you'll probably like.

Well, ok... Teaser :P
Though I *do* have a 1.2kw ATX PSU under the desk feeding my R4 office heater and since the big PC 24pin connector only has a run-jumper in it, nice source for the (multiple) 5v to feed the ports and 12v for the hubs USB circuits via the existing regulator in it to run the hacked hub...

Following this thread... found out GAW finally got prosecuted so figured I'd check into hardware again.   ;D ;D

It's been prototyped! Sidehack's got a small podlike miner that hashes without fans at around 100ghs. More information can be found in Hardware. If you're anything like me you'll absolutely love this one :)

Oh by the way, every small-queue order placed before I started telling people their order would go on the second batch has been shipped. So if you bought 2Pacs more than a week or two ago and you haven't received them by the middle of next week, get in touch with me and we'll figure out what's up.

Let it be known, every order placed now will go on the second batch.

Received my 2pacs yesterday - setting up today, thanks!

Gekko hub?

Yes, no, or maybe?

Sorry if i missed the update been out of pocket for a week

No update, haven't had time to work on it. Got all the parts, just not the time.

Still taking orders?

For batch 2 which starts manufacture this week.

Holding coin for Terminus

Where did the name come from?

Is it gonna lock me in a train car and try to eat me?

@sidehack - Are there still some sticks available? I'd like to buy 2 please? Shipping will be to South Africa.

$30 x 2 + $? for intl shipping = $?

Im here looking at it so ill say it,

- read the thread and all your questions will be answered...

Okay, new rules for purchasing.

I don't know how many times it's been stated that sales are open. It will be very well-known if sales are closed. So I will no longer respond to the question "are sales still open?"

The squeaky wheel gets the grease, but past a certain squeakiness threshold the wheel gets discarded. To this end, I will no longer respond to multiple identical purchasing requests sent within the same 12-hour period. If you want something, ask for it and be patient. Impatience is annoying.

I'm a builder, not a babysitter, so I won't sell to people who haven't done their homework. If you can't correctly identify the thing you want (for example, there is no "gekko stick", no "compaq" and no "2 pack") I'm just going to ignore you.

I really really like the parts of my job that are designing and building stuff. I really really don't like the parts of my job that are nickel-and-dime sales to chumps with bad spelling, so I'm just going to cut that part out. I like money but I don't like being annoyed all the time by other people. So if you want something, find out for yourself the sales status, find out its actual name, and politely ask for it one time. If you can't do that, go bother a reseller.

To make it easier why don't you have an online sale for the products you sell so they can just pay online, and not bother you?

Um, okay. How about I only do bulk and reseller orders from now on, so the only option for anyone is to go through resellers' websites and I never get bothered by anyone except the people I already know I like? Then I don't have to spend a week redoing my website and I don't have to give a leg up to the community I expect to try a little harder than the average jackass.

Or maybe I'll continue to expect more from the average jackass than average jackassery (that's not going to stop) and hope people follow the very simple rules.

Totally agree with that Sidehack. Don't waste your time with the average jackass. You need time and focus to work. Keep your good job buddy.
Btw, Canada Group Buy is now at 12 sticks.  ;)

https://i.imgur.com/5lzkmcl.jpg

I finally finished up my 12 port USB hub project!  I'm pretty happy with it.  This is the first time I've been able to get all 9 of my 2Pacs working at once.  The one stick on the side doesn't work when connected to my hub but has no issues with the Anker.  I also won't power up if I use a USB meter on it.  Not a really a big deal though. 

I still have a little more work to do with the power supply.  The fan that was included with it was way too loud.  I don't care for it being open so I'll get that covered up eventually.  :)

Thanks to Sidehack for the 2Pacs and others on this forum for the ideas that led to the USB hub.

What sort of rate do you get from these 9 units?

Can't wait for my 2Pac to arrive to start playing.

Don't forget, there is a Canadian Group buy if you want some stick.  ;)

Hi,

I am in for 7x "GekkoScience 2PAC - 2x BM1384 USB Stick Miner" and payment was made to your paypal account.

Thanks,
Coinwally

I know. You told me five times over a weekend and then paid the wrong amount. Next time BE PATIENT.

Apologies just excited I guess... PM me for any corrections.

Hi,

Can you please acknowledge if you have received payments (paypal)... Let me know if I make any mistake.

I dont want to bug you but my excitement getting increased day by day  :)

Regards,
Danish

Yep, and all current orders will be shipped out tomorrow. Starting from now, I should be able to meet most orders from standing stock with minimal delays.

Any ETA for the EU sticks? No news on bitshopper.de.

They've been delivered. Scheduling is out of my hands now.

Woohoo, 2nd stick ordered in time. Thank you @Sidehack

Transfer done.

As of right now, ALL ORDERS have been shipped and I am completely caught up.

I'm not sure that's ever happened with stickminers before.

and hopefully this time you got to exchange the btc received at a decent exchange rate vs yer usual luck with that...

You are awesome bro! I cannot wait to fire them up. :)

Thank you sir! Much appreciated.

Any possibility on tracking numbers or am I ahead of the curve again?

Happy Dance  ;D  ;D ;D

2Pac EU version will be available in May 1 at bitshopper.de for EU guys  :)
https://bitcointalk.org/index.php?topic=1887243.0

I am super stoked. I received my 3x 2PACs today! They all appear to be functioning well straight out of the box with my RPi2 on a 60w powered usb hub. Now, I only need to do a little power optimization. :)

I am so jealous right now  :D

It looks like I am getting about 6.12w to 6.14w per device with a frequency of 175MHz at the default Vcore of 1.26v. The hashrate for each is pushing about 19.1GH/s to 19.2GH/s after a few hours on p2pool at a manually set difficulty of 32. One of the sticks does seem to average about 1 HW error every 30 minutes. I bet if I up its Vcore one notch it will drop.

I have to say that I am really happy with the current result. Oh, I cannot forget the blinky lights! I love the fact that sidehack includes them. HaHa... He certainly thinks of everything.

Truth be told, designing the blinky light circuit was my favorite part.

Humbly requesting some pics please @in2tactics?

Hmmmm - Disco ASIC miners, now that is a reason to throw a party while mining crypto-currency  ;D ;D ;D

@in2tactics, I agree with jaco, you cannot leave us hanging like this man... pic us!!   ;)

Thanks

While we wait for our SA shipments Wally, we can look at this and pretend it's ours :P

https://www.youtube.com/watch?v=eyI6l8CwoxA

https://www.youtube.com/watch?v=IRDqdZxU2Q8

I asked my wife what she thought of the lights. She responded with, "they are very nice. Now, make those disco thingies go away." Mission Accomplished...

Apologies, you are right. I should have uploaded some pictures. I will get those uploaded tonight.

As soon as I had a working Compac, I built like ten of them and took them home to run overnight where I could observe performance. It was fun having that many flashy lights in the room all night.

I meant that too though, that the flashy light part was the fun part. Power was fairly straightforward (when I finally got it working, the production version was by no means the first draft) and chip comms were very straightforward, but the flashy lights part was fun. It's actually got a double NFET inverter triggered off the RX line, where the second FET has a parallel RC on the gate to hold it high longer and that's what kicks the R and B elements in the RGB LED to make the white-ish flash. Without that the flash would be imperceptibly fast since a share return is like 5 bytes at 115kbaud. So it's not complex at all, but I like to think it's at least clever.

The Terminus uses a similar circuit, but instead of the RGB LED it's got a discrete blue LED and discrete white LEDs that flash. That way there's no weirdness going on with white-balance. Keeps it consistent. And also dead sexy.

Additionally, to stay on the subject of selling 2Pacs and whatever, I shipped out more orders today. We're operating out of standing stock right now so orders are shipped "immediately". I put that in quotes because I only actually send out packages on Tuesday and Friday.

That is great news on the shipped products, I feel like I played the lottery and am waiting for my prize to arrive. The anxiety is palpable  ;D
Maybe just a SIDEnote 8), if the Compacs can end up making us coffee and toast in the morning while flashing disco lights then I think our lives would be complete...

Here are the pictures as promised.

Any chance of another round? I'm looking to get back into mining and a few USB miners would be a nice low-cost 'reintroduction' to mining.

Another round of what? Sales are still open. I've already shipped out about 200 batch-2 units.

YOUR BANNER SAYS THAT YOU WANT S5 BOARDS--

I have a number of S3 and S5 units gathering dust.  What do you offer for the units?  Do you only want the board components?

From what I read here you are designing a replacement component for the S3 or S5 miner that an be used instead of the original chip board.  Is that correct?

I have been reading your BitCoinTalk threads for a while.  Your projects are always fascinating.  Please take the time to post an answer.       --scryptr

What I can pay will depend greatly on where you are, what with the cost of shipping. Let's take this to PM.

Sorry I must have mis-read the initial post mate. No idea what I was thinking haha. By the by, I saw that Eyeboot.com were covering Asia. Do you have anyone for Australia? I would like to buy locally if possible.

Nope. Eyeboot is out of Hong Kong, Valkir out of Canada, bitshopper.de out of Germany and then the regular US sellers is all I have. Nobody in Australia.

Looking to buy some USB miners for 'shits & giggles'. Anyone point me to a source willing to take BTC and ship to Australia?

Page 1 contains all information you need (Pricing and Payment address), just confirm with sidehack what shipping costs to AUS will be.

Any way to get any of these GekkoScience 2-PAC shipped and landed at this moment? (to ontario, canada)
@Valkir ????

Hi,

I don't have access to my sticks at the moment, can someone please measure the dimensions of the heatsink?
I'm trying to see if I can make some improvements to the way chips are cooled by adding a small fan on top.

Thanks.

Later edit: I'll have to measure everything precisely, but basically this is what I'm trying to do. :)
The fans on each stick will be connected to a USB male (3-5 cm) which will go into the hub.

https://image.ibb.co/eUF7GQ/download.jpg

25x40mm

Do you ship to South Africa would like 4 or 5 depending of shipping costs 

Sorry dude, I'm using being too busy (whether it's true or not) as an excuse for ignoring people. Really though, I had some bulk orders come in this week (resellers restocking) that chewed up pretty much all the rest of the batch so sales are closed until I can figure out if I'm gonna have anything left to sell once all current orders are met.

no problem , let me know when you got some stock , would probably be taking 5
Thanx

We (SA folk) should do a group buy for pods for SA.

you are not satisfied with a usb fan? you can bend it and cool multiple sticks:
https://www.amazon.com/ARCTIC-USB-Powered-Portable-Solution-Gooseneck/dp/B003XN24GY

I agree , or a reseller because the price per unit on here works out to about R500 (depending on shipping costs) and the only other GekkoScience 2pac miners I can find are all over R1000 and out of stock.

Thanks for the Arctic link, a few other members pointed me to that product and I know they're good (I do use Arctic PWM fans for my PC case and they do a nice job).

In other words, I'm satisfied, but not 100%. Currently I'm using some other type of USB fan (15cm diameter, see pic below and don't laugh at the red color - it was the only one in stock) and the heatsinks are kinda hot. Not burning hot (ie: I can keep my finger on them) but hot compared to my other gear (Baikal miner). And I want them to keep working for a long time, w/o risking overheat failure.

Oh, and yes, sidehack's way of building things makes me want to start tinkering again - that's one reason also. :P

https://i.imgur.com/J2M1RtK.jpg

Happy hashing!

Placed my order a while ago and it is currently at JHB customs so - YaY!!! ~Gooo Customs

If there are more SA guys considering to buy maybe we should consider creating our own SA Group buy so that sidehack only deals with one crazy at a time  ;) [ME INCLUDING]...
Just waiting to see how long it takes for my sticks to go through customs... currently standing on 6 days and counting.

Anyone interested in purchasing direct from Sidehack here is the shipping costs I was quoted
Standard Shipping: $ 15 - Local postal services are used when it reaches RSA
Fast Shipping: $ 47 - Still waiting for my delivery to verify if there are any release fees and how it gets delivered

Once I have an idea of how long it takes to clear from customs and what the waiting period is from start to finish delivery and if there are any release fees then I am sure we can make a plan.

How do you know it is with customs.. di you recieved any calls from them.... just curious as waiting for mine

I opted for fast shipping and got a tracking number, I then requested USPS to mail me an update the moment something happens, last update was - Your item cleared customs in SOUTH AFRICA at 10:31 am on May 15, 2017.

So it is on its way to me and I am so excited, I just can't hide it...  ::) ::) ::)

Expecting Speed Services or some courier service to hopefully surprise me by Thursday or Friday or maybe next week who knows... That's all part of the fun and mystery that is SAPO.

I would be keen for the pods.
I want a few pods to replace my S3.

Well, looks like I'll be doing another 2Pac batch. These things sold out pretty fast and I'm still getting requests.

That's good news, I'm looking forward to see the first BTC block mined by a 2Pac. ;D
As a side note, I've made some (minor) changes to my setup - added some angle adapters to change the position of the sticks. Cooling seems to be better now; adapters are not getting hot and performance is not degraded.

https://i.imgur.com/HSyJOz6.jpg

UPDATE: So picked up my package at my local post office today - YaY~, for the SA guys it takes a month to get your package (on fast shipping) so extreme patience is required (my crux).
As for the $15 shipping my one contact informed me that his package is still in transit, so strongly recommend not to go for the $15 option when shipping to SA.

Now just to build up stock and get my mining on...

I'm still waiting for my 2Pacs down here in SA?  ???  :'(

I believe you. The South Africa postal system, at least for packages from the US, has been reliably terrible. We had a guy a few years ago wait three months - with multiple calls with all available information - for a box of PSU kits. If the guy who paid for fast shipping just got his a couple days ago, no idea where the slow shipping package is. They shipped at the same time.

It arrived today!!! So stoked. It's in and mining for their future USB Hub home :)

Also, a reminder for folks who might have missed it.

Hi,

I was considering the same hub for 5 sticks. Do you think there is enough room or should I get larger USB board?

pm send

Correct me if I am wrong, these sticks hash around 100 GHZ with 100-120 watt power and uses Rasberry PI with CG miner and only mines Bitcoin?
If so, can you make something for Scrypt mining as well?
Thanks so much. Well done as well.

Yes, you are wrong. About pretty much everything. Read the first post.

My bad, got it...60W hashrate about 190GH, with a 100W hashrate of 250GH. PMing you.
Thank you so much.

No, that's still incorrect.

Oops. Sorry mate! Now its your turn to correct me with particulars. Thanks in advance.

If you read the "whole" first post, you can easily find the table with hashrate versus power for the 2PAC. If you are still having trouble, check immediately below the pretty picture. ;D

PM Sent. Looking to grab a few from batch 3.

Without considering new product design, hosting maintenance, Terminus prototyping and manufacture, or taking the occasional Sunday off, I've got enough work lined up just witn 2Pacs to keep me busy through the end of July.

One thing that gets in the way of being able to build the crap out of stuff in a quick and efficient manner is communication. These days I'm getting a lot of emails from randos all over the world asking if sales are still open. It's easier to find a notification that sales are still open than it is to find my contact info. This is annoying.
I also get a lot of emails from people asking for help with the one stick they bought from some dude on eBay. No offense to anyone, but if you didn't give me your money I don't actually owe you anything. You probably paid a substantial markup to someone else, and because that person got your money that person owes you support. I'll pick up the slack if that person drops the ball, but don't come to me first because I'll turn you away at the door.

So with all this in mind, mostly in an effort to reduce having to ever talk to other people because I'm a crusty hermit who enjoys sitting alone for hours on end assembling various things without interruption -

Individual (non-bulk) sales for the 2Pac will close as of June 16th. After that, any purchasing requests below a threshold reasonable to be called "bulk" (so, couple dozen or thereabouts) will be ignored outright.

Any email saying "I read your thread, are sales still open?" will be met with a cynical response linking the part of the thread (you claimed to have read) answering that question.

Any email asking for support will be met with "If you didn't buy from me, talk to the person you bought it from."

So, feel free to grumble that I'm not being very nice. Won't change the policy.

Looking to buy couple of 2PAC, I already sent you PM. Thanks  SIDEHACK

No, it's not about room, it's about how much amps it can deliver / port.
Don't buy it if you plan to use it with more than 3 sticks. Otherwise, decent piece of hardware.

Cheers!

Is anyone doing a group-buy in the US?
I would like to get some of these and a larger batch would help defray the shipping costs.

Um, they're made in and ship from the US. The shipping cost is constant regardless of batch size within the US.

Sorry, all of the ASICs I have dealt with are made in China, so I assumed the same here.
What is the price for the 8-chip "pod"?

Probably $65, once it exists.

Thanks, what's the anticipated timeframe for availability?

Currently there isn't one, which means it's farther out than I would like. Prototypes have been working for months, the final board design is almost complete but should have been finished a couple weeks ago. Right now I have enough work stacked up to keep three of myself busy full-time and helpers keep disappearing on me.

if your located in FL I will help you out :)

So, what's a good recommendation for a hub to power these miners?

Batch 3 manufacture is underway as scheduled. However, my chip source kinda disappeared on me for a week or so; I was expecting a truckload to arrive today but it actually hasn't been shipped out yet. What that means is, I'll have a few days downtime between these first few sticks getting finished and the rest of the batch getting started.

I'm not too upset, because that allows me some time to work on a few Terminus prototypes I'm going to put up for auction to raise money for a friend's medical bills.

It also allows me to waller out some production bottlenecks by setting up a second reflow oven and second testing station.

Oh and also once the truckload does arrive (I'm basically just buying out a retired mine) I'll have something like seven thousand chips, which is enough for all of Batch 3, all of Batch 4, all the remaining bitshopper.de sticks ordered and a couple hundred Terminus pods. So I shouldn't run out again for a while, and running out of chips has been the cause of a lot of delays so far.

I hope your Terminus prototypes workout as planned. ;D

Ya know, just a few threads down from this one there is thread on power hubs for these sticks..... Read it ::)
https://bitcointalk.org/index.php?topic=1779423.msg17745347#msg17745347

In particular, this part of it which most likely applies to most other make/model of power hubs talking about how the ports are powered

Auction for some prototype Terminus pod miners.

I've also got some "factory seconds" 2Pacs I'll sell, profits from which will go to the same thing as the aforementioned auction (https://www.gofundme.com/lauras-eating-disorder-recovery). These 2Pacs were ones which failed final testing because, at stock voltage settings, they either were not fully stable or ran too many HW errors. They'd still work at a higher voltage, but since they were too far out of spec I wouldn't ship them for regular orders.

So let me know if you're interested.

Is it available for Canada at a decent price ? I can buy some!

Question for anybody who knows.

I know this is a essentially a one man operation.  So should I expect any sort of notice when my 2PACs ship, or will they just appear in my mailbox one day?

They'll probably just appear. It's statistically likely that your order will ship between last Friday (7 July) and two Fridays from now (21 July) depending on your order in the queue. I've shipped out over 360 Batch 3 sticks in the last two weeks and by the end of this week that should be closer to 700. Pretty much everything after that point is bulk orders.

Out of interest.
How many minions are in your production team?
What is the estimated stress test on the 2Pacs and pods?

I currently have one full-time minion, which is the most minion I've ever had. Just started last week. I have another guy who occasionally helps when he has time but he's also a general handyman for a lot of folks around town so he stays pretty busy.

Every 2Pac is run at 100MHz stock voltage for 30 minutes. Every one that passes (no dropouts or HW) are writted with a serial number and run an additional 30 minutes. Every one that passes gets shipped. Hence why I guarantee stock specs and overclocking is "at your own risk".

Very interesting. So for the most part this has been a solo operation. Its alot of work to get to 700 stable units.
I look forward to the pod miners. Both BM and BF pods.  :)

I had a part-timer working between classes February through April, the other guy helping out some in May and June but not a lot. I've been basically manufacturing solo for the last two or three years.

What city?

One far away from you, one reason why I've ignored offers to help.

I wouldn't mind taking some of these from you if still available.

thanks

I would also like to get my hands on some 2pac if you have any for sale?

still selling these?

Depends which "these" you're referring to - the "these" that I specified wouldn't be available for general purchasing after June 16th, or the "these" that I posted last week I had a few of for sale. For at least one of "these" the answer should be obvious.

Any news when we can expect next batch? Bitshopper is out of stock right now...

Be more useful to talk to bitshopper, or in bitshopper's EU sales thread.

What thread is that?

Is there a new project going on, since it is imposible to get any one of 2pac?

If sidehack (https://bitcointalk.org/index.php?action=profile;u=130792) and the other official sellers are okay with it, I have 3 brand new 2pacs that I don't have any empty USB slots for (otherwise I would definitely be using them). If sidehack (https://bitcointalk.org/index.php?action=profile;u=130792) gives his blessing, and you agree to purchasing the sticks as "used/as is" (even though they are brand new and have never been used) I will open a sales thread for them AFTER (and if) I get an okay to do so (and the people asking still want to purchase one)..

Dude, it's your stuff. I can't really tell you not to sell a thing which you own.

Would like these. LMK if still available.

Sidehack replied to a post giving his blessings if anyone wants to sell them, he's fine with it.  He replied on: September 18, 2017, 11:47:38 PM

Please let me know if you still have them available. I'll take them off of your hands.

Thanks

Are bulk orders for 2pacs being accepted now?

Yep. Got a five or six week backlog though, trying to pick it up if I can get some more help around the shop.

Hi, sorry newbie jumping on the thread I'm trying to get up to speed.

Do you ship direct to UK or do you have a UK/European distributor or reseller?

I'm after up to 10 2pac if you are still making them?

Thanks

Do you happen to know if any US distributors have any in stock?

ASIC puppy has them listed, but it says 30 days for shipping.

Great, what is a minimum order you'll accept for Shipping in the US?

 I?ve done a lot of business with crazyguy over the years, and would definitely trust my purchase from him. He has a topic in the Hardware forum.

 https://bitcointalk.org/index.php?topic=612390.660

Stupid question but are these available for sale in USD?

If not are there any other coins allowed for payment outside of BTC?

Thank you in advance.

I see Bitshopper doesnt have them anymore.. where can I get some ? maybe 2 for my personal use.. any other site selling them in Europe ? or any place ?

There's quite a few on eBay - expect to be paying a premium for them though...

Bitshopper should get a shipment by the end of next week, so he may list stock again.

I now have an official sales rep, so as soon as I have general stock I'll re-open sales with some stock queued for small direct sales. Probably 90% of them will still go to resellers, but there will be a weekly reservation just for small orders.

So, we're still ironing out the details but general sales are open (with limited stock).

Email our polite and classy sales rep Laura (laura at gekkoscience dot com) for purchasing inquiries.

Still a way to get one of those? They are out of stock everywhere. Thanks!

Regards

hi sorry if this is a silly question but what file holds the OC/frequency settings? i cant find anything and i'd like to try and tweek it up a bit

Anywhere else to get one besides ebay? Anyone know any other reputable sellers of mining sticks? Thanks

In the US
Holybitcoin still has them on the site.

Unless you have a reason for wanting this model I would go with the NewPac stick instead
