[RUN 2 CLOSED][SIDEHACK STICK]GekkoScience Compac Official sales thread

Can somebody tell me how much time does it require to get your money back (ROI) ?

You won't - these are not intended to break even, let alone give you a profit.

Calculators are whack, but you can start with this sample simulation:
https://coinplorer.com/Hardware/Simulate/55e83fe0226bf410a453eeb0?key=4802c38f-0b0d-42da-a01c-5c288480c125

It assumes $25 to buy it (no shipping added), 16Gh/s at 0.35J/Gh (you can over/underclock), a constant difficulty (won't be so), BTC25/block (won't be so come half-way next year), no pool fee and no electricity costs.  You can see that the time for it to break even in those unrealistic circumstances is still 2 years from now.  Almost all of the aforementioned assumptions changed to more realistic values is only going to make that worse.

Thank you, and what i see Fun > ROI is very true

Can somebody tell me how much time does it require to get your money back (ROI) ?

You will get your ROI right away when you turn it on and start smiling.

It meant it take lots of time thank you.

What kind of cooling would we need to keep a stick at 250mhz? xD

I've got a pretty weak 120mm fan cooling 9 of them, and they are maybe 10 C hotter than room temperature when running 250MHz- and this is in a hot shop, around 35 C.  Probably whatever fan you have is fine for a couple sticks, especially if you're only going to 250.

 

Excellent   Though I haven't had much trouble getting past 250, the new initialization routines should make it easier to get it above...wherever I left off.

Yeah, well, most people can't build cgminer or modify it themselves, especially on windows.  I've also got a stick to run 425MHz stable/low HW errors, although that just playing with one of the older ones.  It's probable you can beat that if you either get a slightly better chip, better cooling, or one of the v0.5s that you can't explode the chip by going into the "dead zone." (which would help you get a few extra mV).  The new top clock is 500MHz which is the highest I have hex values for.  That's pretty sporty for a USB stick as 425MHz was pulling about 2.5 amps on the USB port.

will you soon have a link to load the new version of cgminer.  I would love to run at 325 or 350.  vs 250.

The new top clock is 500MHz which is the highest I have hex values for.  That's pretty sporty for a USB stick as 425MHz was pulling about 2.5 amps on the USB port.

Yeah, things get a little 'interesting' electronics-wise  As sidehack mentioned, the connector isn't even remotely rated for that.

I've got a whole sheet of frequencies and hex values, but most of them are unlikely combinations of the various multipliers/dividers and some overlap; e.g. 200MHz fits 00111110000011 (0f83) and 00011110000010 (0782).  The latter is what is specced in the chip's datasheet - the series difference between them being the output divider value.  There's values well over 500 but I haven't even remotely approached 500 as it fails to initialize long before then  Looking forward to the new drivers - might poke at bfgminer as well, glad there'll be support in both

[Mikestang]

They're not cheap, but CoolGear makes some bullet proof usb hubs.  I use this one for my stick miners (I run 4 nanofury sticks, soon to be replaced with 4 Compacs): http://www.coolgear.com/product/metal-7-port-usb-2-0-hub-w-din-rail-mounting-kit-japan-nec-chip

I also have one of the usb fans mentioned previously.  Once my Compacs show up this stick set up should out perform one of my old U3 miners (which are just sitting on my desk gathering dust now).

[Blackbird0]

What's the shipping update at this point?

[sidehack]

As of right now I have 21 completed sticks which need a bit of Novaking and a quick test and they'll be ready to ship. Tomorrow I'll be cutting out of work early (3PM instead of 10-11PM like the last 5 days straight) so I might not get a lot more done. But we'll see. If I can run up about half a dozen more tomorrow I can ship the first 8 small orders.

I've just been using the same hex values as the S5 (view source on the config page) so I haven't had trouble with them yet.  I got the stick to run at 450MHz but so badly it's hashrate was lower than 425MHz, and there were so many errors it probably was worse than 300MHz.  Also just a note:  I think Luke-Jr is planning to release support soon but as far as I know right now you need to build the "compac" branch on his github if you want compac support on bfgminer.

will you soon have a link to load the new version of cgminer.  I would love to run at 325 or 350.  vs 250.

Yeah I intend to post it this weekend.  The compac seems to do ok at up to 200MHz or so on stock ~=0.6V voltage, you probably need to bump it a bit to go over that, and 300MHz probably needs close to 0.7V.  If you only have stock USB power you can get it to run 150MHz or less actually undervolted to maybe 0.58V (this is under spec for the chips so it may or may not work on a given stick but I've seen it).

Sent the 0.242536 BTC ($56) for 2 Compacs to 1BURGERAXHH6Yi6LRybRJK7ybEm5m5HwTr.
Shipping address in message.

Thanks!

Yep, I'll try to get 5.3.0 released before any deliveries take place.
Note I merged and deleted the "compac" branch, so just the main "bfgminer" branch is fine now.

I've poked around here, and I just can't seem to find the MHz to GH/s ratio for the BM1384 that's on this stick. As I understand it, this is a fixed value based on the design, and is probably dictated by the number of replicated hashing engines within the ASIC.

Does anybody recall what this is?

MHz*0.055=GH/s (max theoretical)
eg, 200MHz is 11 GH/s.

Big news, folks. The first ten small orders (that aren't going overseas, sorry TheRealSteve you'll have to wait for Monday) are heading to the post office right now.

I'll be out this evening and most of the day tomorrow, but between Sunday and Monday I hope to get another at least 30 sticks going. That coupled with the ones we still have will catch me up through the first big lot and all the pending international orders.

[TheRealSteve]

sorry TheRealSteve you'll have to wait for Monday

All good - and good news!

[brush242]

Is there a recommended USB hub to run these on?  Say for up to 10?  I am planning on using a Rasberry Pi 2 eventually but may start with a regular desktop PC.

This could run 9-10 @ 1amp each:

http://www.eyeboot.com/10-port-usb-hub

Comes with wall mounts and never gets hot

Any word on the free shipping on Amazon theory?

I have several, would like several more. Great piece of kit.

I have one of those nice powered 10 port hubs so I am ready to go as soon as mine arrive. I also just ordered the 300Watt power supply and cable for the 49 port eyeboot hub i had floating around just for these sticks

I had one of those 49-port hubs I got damaged off CrazyGuy sometime last year but I fixed and sold it 'cause bills were due. I'm kinda wishing I'd hung onto it instead. I mean my little 10-port is nice but it's not that nice. Maybe I should build more. Or get a forty-niner. I still have some 30A power supplies, and if that's not good enough it's not like I can't build one better. I mean a slight change to the TypeZero power systems as designed would get me upward of 50A of 5VDC. That'd run a lot of sticks. I could fill the hub with 250MHz sticks and get about 670GH off that 50A. I wonder when was the last time someone had 670GH worth of stick miners running together? That would have taken 2000 Block Erupters. Dang. Actually, let me do some checkin' and see if I can't scrounge one of those up.

Speaking of, I should probably post pictures of the thing full-up with proper green-heatsink Compacs running on Novak's cgminer. I think we had about 8 plugged in when I left the shop this afternoon. They'll be swapped out with more in the next couple days.

Apparently Monday is some sort of labor holiday ("Labor Day is observed in the United States on the first Monday of September to celebrate the achievements of workers and the labor movement") which means the post office is closed and, I dunno, people are supposed to take a day off work? Yeah like that'll happen, dangit I got sticks to make. So it looks like shipping will resume Tuesday.
