Thanks to Cscape for hand-assembling these boards! This is long, neck-wrenching work to do all this by hand!

Wow, that must of have been painful. Im completely useless with a soldering iron.. but the little I have done makes me appreciate anyone capable of doing work on this scale.

Nearly all the work is done using reflow technique, so there's very little hand soldering involved, but a lot of manual picking & placing with fine tipped tweezers. Each board has 240 capacitors in 0402 size, and about 60 other components.

you are insane. respect!

Good news: BitPay problem fixed! Tricky little bug.

Bad news: CC payments are currently being handled in manual mode only (choose Bank Transfer and make a note on the order) while I set up a new payment processor. Kat can process your card manually via Square for now. It may take some time to get a new merchant account. Sorry for the inconvenience!

What is the size of the mounting holes on the m-board?

Mounting holes in the PCB are 3.2 millimeter, designed for M3 metric thread.

I really really really really hope...

you guys can meet your said deadline...

I am saving some money to get the 400GH on October...

Likewise, in the same boat

Just waiting for BTC to get high enough to push these from good deal to great deal.

FYI CC payments through the site are currently turned off. If you want to arrange payment, use the bank transfer payment method and note that you want to pay via CC. Kat can process your card outside the site. I expect to have a new payment integration done in the next couple days.

Cheers,
Dave

That looks awesome, already been working to fund one of these myself

By the way, this project would go nicely with Bitfury rigs for standard ATX power that takes care of both the boards and the Pi:

https://bitcointalk.org/index.php?topic=263567.new#new

I know this is still in a prototype stage, but are there any specs available as far as the physical aspects (Size, mounting holes, etc)? Like many I'm sure, I am wanting to start mapping out some kind of mounting system/case.

I looked at that too for my enclosure but I don't think it will work because the hboard is using the GPIO pins and so do that little switching device.

It was stated the cards will be mini-molex by Buzzdave on the next revision

Victory! Missed that, I'll have to change the front panel on mine now!

I was thinking more about shriking the H-boards, not the m-boards. right now, there is a decent gap between each bitfury chip that could surely be reduced with some design revisions or adjustment of resistor placement. However, this would still increase the heat density...

Yes, the gap is purely for spreading heat. There only a few little components, and a few traces between the chips, so, electrically, the gap could be reduced to almost zero. It's the heat that is a concern.

Dave,
for a display on the RPi, you might want to look at:
http://www.ebay.com/itm/USB-2-8-TFT-LCD-module-LCD-sys-info-display-temperature-fan-AIDA64-LCD-Smartie-/121004607232?pt=LH_DefaultDomain_0&hash=item1c2c6fc700
This is the one with the frame mounted, they also have a frame less version and they work off the USB connection

The code could be incorporated into the cgminer fork being developed

there is a decent amount of PCB space between boards. Is there a reason for that, or will version 2 boards be designed more densely in order to shrink the size?

There are no plans to shrink the size right now. Of course, the closer the boards, the more difficult it will be to get the heat out. Maybe after more real-world data, a size shrink could be done.

So far what is the wattage use of the prototype?

I put in a refund request today on the website, will update and let everyone know how that goes. (Ordered 1 25gh/s kit + 7 h-boards for ~49 btc.)

Can I inquire why you would want a refund?

My guess is that he doesn't believe that 200GH received at the end of October will return 49btc in its useful life.
My calculations are very rough, but I get 54 total BTC... so a very slight profit but risky. If BTC price can get up a bit higher, I am interested in the october delivery, but with current prices, the risk/reward just isn't there for me yet.
My calculations may be ridiculous though as I am forecasting 130M on Nov. 1st.

I am forecasting ~150M on Nov. 1st with an avg of 20% diff increase per cycle until then. With that model, 200 GH/s at 49 btc never pays off. What might happen though is in a month for now diff is so high that Bitfurry slashes prices for current orders to keep everyone from backing out, and then I cry because I lost my place in line
