141  Bitcoin / Hardware / Re: Gauging interest in a S5+ / 3xS7 specific power supply breakout board on: October 26, 2015, 07:55:15 PM
I'll get a small test batch of 50 PCBs next week.
The first orders will be able to ship before the 6th.

In the meantime, I've started the assembly of the voltmeter to make it modular so you on't need one on each breakout baord if you don't want to.

I'll update the first post later with a few extra pics, price, and probably list of confirmed interest.
Will start to collect funds this weekend or beginning of next week.

BTC payments will go as usual to my 1J4bberW... address.

He must have free power, its not been profitable to run S1's in the UK for a long time because of our high electricity costs.
The vat cost is going to suck!

As far as I'm aware VAT is only applicable if he's buying from a business, shouldn't have VAT if its a private seller.

Could be wrong though I'm not sure about this to be honest.

Unfortunately for us all in the EU, you are wrong.

Whatever you buy that is valued over 25€/25$ outside EU will be charged VAT +  carrier fees for doing the paperwork when it arrives in EU.
VAT applies on the value of the item and on the value of the shipping, and of course on the fees charged by carrier company (DHL/FedEx,UPS...).
Only if you use Airmail, you can sometimes go through without paying VAT (usually works quite well on smaller packages).

I even had to pay VAT and fees on some of my own breakout boards sent back by Holybitcoin for RMA.

Simple example, you buy an item that is just 25€, with 15€ shipping on top, you will end up paying an extra 23€
8€ VAT on item + shipping, 15€ fees to the carrier company (average value for FedEx/DHL)

And the worst is that if you buy something with free shipping, the carrier company will still make you pay VAT on an arbitrary shipping value they will add over the item value.

So something that is 25€ with free shipping can sometimes translate into an extra 23€ VAT + fees too.

Hi all,

looks like jabber is really busy at the moment, is there anyone in Germany who could provide a 2880 breakout board and at least 6 pci-cables (36" HQ) ?

Regards
Stefan

You can' imagine how much I'm busy. I've been unavailable for 2 weeks, and have tons of PM/Emails to answer, and boards to manufacture.
Your message is still in the "to read" list.
To give you an idea or price, boards are 60€ for small orders, cables, 3€ each.
I also have some IEC C19 cables with EU plugs, 2 meters long, for 8€.
Shipping to Germany should be 18-20€, maybe a little less, but I won't be able to ship until next week.

I'm pretty sure that the price will goes up, cuz of coin price.
They should drop the price, it's already too high.

And BW announced this week plans to sell 14nm miners to the public, which threatens the already unattainable ROI at current S7 prices even more

“The chip promises to be the cutting edge technology that BW prides itself in producing. We will also be offering the 14nm chip in a miner for consumers. The power, efficiency and noise reduction benefits aims to introduce a new standard to the industry.”
https://bitcoinmagazine.com/articles/the-unknown-giant-a-first-look-inside-bw-one-of-china-s-oldest-and-largest-miners-1444675310

was hoping to get a couple S7 for heat over the winter and selling it in the spring with the hope of breaking even..but doesn't sound like there's a good chance of breaking even on the S7  Undecided

According to this link,
Quote
BW was co-founded by LK Group Limited and CHBTC on Aug. 10, 2014
So I assume they are simply using the Innosilicon A3/A4. Nothing really that impressive, and not a real game changer unless the price is very low, but that seems unlikely on 14nm.

Not 100% sure if it's the same cable on Alibaba. Usually there is a minimum order quantity and length is customizable for as low as $.25.

It just take me to a login screen, and i can't find them on ebay using that name. If someone buy a batch, let me know i'd be interested. Even easier if you buy it to Canada. I don't know alibaba but if they can sell a batch and ship it to my address, maybe a 3rd party that know Alibaba could do the deal. Then it'd be easier to ship them out to whoeever need them.

But i'm guessing this is probably what Jabberwock is doing anyways so we can probably wait until he has a batch for sale.

I'm dealing directly with a connector and cables manufacturer who is making me those custom cables for the S5/S7.
I'm buying them with larger batches of my other supplies from him to save a bit on shipping.
As I said I'm not looking to make a profit on them, I'm considering it as a group buy.

Thats good, i'm still waiting to hear back from you. Please let me know when you get the long S5/S7 18 pins long cables. I'd also pick up a couple of 16pin long cables if those are available wherever.

he says ^^^^ that he has 180 of those in stock already.
https://bitcointalk.org/index.php?topic=1173573.msg12708774#msg12708774

shipping for multiple is expensive, though, maybe we better off if someone will get 50-100 in US, then we can get from that person. I am good for 4-6.

Last message he sent me was that he was out of stock, he has not replied to the thread saying they were on stock since then. But i saw he has a NA reseller, maybe he could send a Batch to him so we can get the cables for cheap.

Sorry, I didn't update everybody in private messages about the availability.
I'll send some to Finksy with other things by the end of next week, he'll dispatch them from Canada.
And he'll probably order some from my supplier if it's not done already.
146  Bitcoin / Hardware / Re: Antminer S5 Mosfet 5pin U3...U50 Need Part Number on: October 17, 2015, 09:50:00 PM
Here,s my best shot at a complete list of IC's on the Hash Board in the S5.

U1 - LM75A - Digital temperature sensor.
U3,U52,U53,U54,U55,U56,U57,U58,U59,U60,U61,U62,U63,U64 - C07F - SN74LVC1G07 - Buffer/Driver Open-Drain Output.
U6,U9,U12,U15,U18,U21,U24,U27,U30,U33,U36,U39 - 4VK4 - LN1134 - 1.85V LDO regulator.
U42,U45,U48 - IR18 - Part No.?  - LDO regulator.
U4,U5,U7,U8,U10,U11,U13,U14,U16,U17,U19,U20,U22,U24,U25,U26,U18,U29,U31,U31,U34,U35,U37,U38,U40,U41,U43,U44,U46,U47 - BM1384 - Hash ASIC.
U101 - 0J - RT8537 - Current mode Boost-type LED driver.


Notes :-

The SN74LVC1G07 Buffer chips are not fitted to the V1.1
The LDO's, except for the last stage are not fitted to V1.91
The IR18 LDO regulators fitted to the last 3 stages are different than those fitted to the first 12, have not identified the PN? They are fed with the 14V from U101 as opposed to being fed from the Core Voltage 3 levels up for the preceding 12.

U42-45-48 are "R18", I think.
That'd be Exar reference SPX5205M5-L-1-8

I'd place my bids on TPS61170 as compatible.
I didn't check the pinout against what is on the S5 board, but it's the only one I've found in 6 pins package with specifications that would match the part on board regarding Vin and Vout.
The device marking is supposed to be BZS, but maybe the one on the S5 board is simply a clone from another manufacturer.

http://www.ti.com/lit/ds/symlink/tps61170.pdf

Am away from Home, but looking at a picture of an S5 Hash Board the Pinout ties up with the TPS61170, so I think a good call.

Rich

After checking the S5 board it looks 90% that TPS61170 belong to U101 ( step up voltage) for S5 hashboard


Nice, don't forget that if you replace U101 with TPS61170, 5% of the hashrate from your S5 will mine directly to my BTC address  Grin

I have a few S5 boards that failed after a shortcircuit, never had the time to check what was wrong, I'll start with U101 output.

quick update 18 pins cables are now in stock.
I was unavailable for 2 weeks, so currently reading all the private messages.
If you have messaged me in the past 2 weeks, no need to send a new message unless I don't reply by tuesday.

I have 180 cables still in stock, so I hope enough for everybody.

Did you crack the nut on the PSU connector shortage J4bber has keeping him making more boards for the next couple of months?

The 3 pins connector that goes in the PSU will be available mid December, if I remember correctly. 15 weeks delay or something like that...
Finksy still have a fair amount of them in hands, and most of my remaining stock have been reserved by "you know who".
I'll also have the 4kw breakout board ready in a few days and first deliveries this month to compensate, if we really end up short of 2880w boards.

Quick update, I was unavailable for the past 2 weeks, so everything have been delayed even if I have all the parts available except the actual PCB for a first batch of 120-150 boards.

The sideplates will be laser cut from 2.5mm acrylic panels like this (first test from 1.0mm foil before my brand new laser cutter died after 2 hours of use)

Hello,

has anyone had issues with their Neptune cubes not hashing? basically being completely dead? long story short, I recently got some busted up Neptunes off ebay that listed that they may or may not work. well the only thing that works is the controller board, but all 5 Neptunes are dead. They are detected by the board though, but do not start hashing at all. additionally, the 'advanced' page shows some VRMS with 0 current output, but it seems the temp sensors are working, however the wattage never jumps up past 10 watts or so on any board. I loaded 1.06s and I was hoping to just dust them off, and have them start up, but no luck. I will take any and all troubleshooting advice at this time. thank you!

I'm not too familiar with them, but they look like dead cores or dead VRMs to me.
Some users here may be able to explain how you can tell the difference between dead core and dead VRM.
Some of my cubes have only 6 or 7 of the VRMs actually showing a normal voltage and amp value.
Some are either very low voltage or very low amps, but I don't care that much since I paid them knowing they weren't perfect.

If by chance you're in EU, I may be interested to buy the full unit (cubes+controller) depending on what you are asking.
One day, I'll find some time to play with the dead units I've collected.

thank for your reply. I am still playing with them, and hoping for the best still. However, i have been messing with the commands in SSH mode, in particular what 'waas' tells...here is what i get at this point...


image hosting no account

i have 4 modules plugged into ports 1-4 on the controller and it seems it is having problems updating the modules' frequencies. I will post more details later today when i get home.

Try to hit reset to factory defaults in the advanced tab.

After that, lower the frequency settings to 400 instead of 475

I am also interested in those long S5 18 pin cables, do you have an open price per with shipping estimate? I guess i'll send you a PM with my information shortly.

This is the first time i try to buy something from J4bberwock. Haven't gotten a reply in a few days. Is this is a normal waiting time when requesting to buy some cables here? I'm not in a super big rush but if its not possible to fill my request, i'll have to try to find another place to get long 18 pins cables, hmm...

I have done business with him before.  He's a very busy man.  He also has a LOT going on right now.  I've had to send him a PM and an email and get a reply the next day or two.  Once he replies and tells you he is going to do something, he does it.  Try shooting him a PM again.  He may respond soon.  I'm not sure about posting his email in the thread.  I would do it if I had his permission but I don't.

I'll wait a bit longer, i am not sure i want to pile up more PMs. If he missed it then i guess eventually i'll send another one, but doesn't he read this threads from time to time too? I guess we'll find out.

I'm very busy at the moment, so I don't answer most of the PM until I have time to give concrete answer.
I actually take a few hours 2 or 3 times a week for the emails/PM.

Regarding the S5 data cables, I should get them in stock just after the chinese national holiday.
I believe I wrote it in the thread about the S5+/S7 controller a few days ago.

Also, I won't take new boards orders until the end of this week.

157  Bitcoin / Hardware / Re: Dragon Miner A1 module hashing at unusual amounts on: September 27, 2015, 09:22:01 PM




here is the datasheet of the LDO chips:

http://www.advanced-monolithic.com/pdf/ds1117.pdf

I didn't check the pinout, but it's very likely that they are compatible with ncp1117, ncv1117, and many other "1117" LDOs, all outputting 1A.
But first, you'll need to check if the Vout is out of specs.
Center pin is the vout.
Most of the time, you can use almost any screw from the heatsink as a ground reference (or simply use pin 1 of the LDO).

I'm not too familiar with the dragon units, but I'm not sure the LDOs are at fault, maybe just the asics that went bad.
from what I remember (but I may be wrong), the I/O are all chained together. I don't know what will happen if one chip in the chain fails.

So to clarify, test the chips to make sure they are outputting 1.8 and 3.3 volts respectively, then go from there.

And it shouldn't matter on the model as long as it is 1.8V and 1A or 3.3V and 1A?

you need to check pinout of the part you plan to buy:
pin1 = gnd
pin2=Vout
pin3=Vin

NCP1117, NCV1117, LD1117A, LT1117 are compatible if yours are sot223 package

but first, check voltage output
158  Bitcoin / Hardware / Re: Dragon Miner A1 module hashing at unusual amounts on: September 27, 2015, 08:28:11 PM
To make a long story short, I've got this Dragon Miner A1. One of the modules says it hashes at 750gh, but in reality it just isn't working. So, I did some research and found out that one of the VRM chips is probably bad (If my theory is wrong please correct me) and needs replacing. So the module apart today and discovered 2 VRM chips, one is a 1.8V and the other is a 3.3V. They have writing on them and I searched it up and found some, but the last string of numbers is different on all of them. Does the last string of numbers matter? I am also not currently sure of the amperage on the original chips. So if anyone knows that info please share that with me.

The 1.8V one is as follows: AMS1117 1.8V H418KE
The 3.3V one is as follows: AMS1117 3.3V H421PE

If the last set of numbers matters could someone tell me what they mean?

Thanks,
dako44

160  Bitcoin / Hardware / Re: S7 controller has nine 18- pin jacks So what can we do with it? on: September 27, 2015, 09:57:58 AM
I have 50 of the 18 pins cables custom made in stock, and also some 16 pins ones for early S5s.
12" long, they were like 1$ each. if I remember correctly.

There are/were for the S5 watercooled case, and some other projects, but it seems that they can serve other purposes.

Edit on availability and pictures


Anyone has the Digi-Key Part Number of the cable connectors?

I΄ve been looking like crazy on this section without luck:
http://www.digikey.com/product-search/en/connectors-interconnects

I would love to build these cables myself. Embarrassed Embarrassed Embarrassed Embarrassed

I don't have the part number, but you'll probably end up paying more than the $1 I'm asking for each cable.
I'm making no profit on those cables.
To be transparent, I'm paying them $0.7 + shipping + 20% VAT on part and shipping.
I'm even probably at a loss if you add the time for packaging and actual packaging.
