last but not least the firmware will be reloaded, sometimes only FPGA0 comes up, and FPGA1 isn't mining

some ideas? i didn't ever change the setup, and that version of mpbm is running for a long time

Also, the majority of people doesn't wanna dump 1500+ USD to an overpriced ASIC, they just wanna try the technology out of curiosity, which is where your board is perfect.

Isn't this an advertisement for GPU approach, not FPGA?  At least with GPU, when your interest wanes, you can still play Solitaire.

Yes, they are all gone, sorry. At this point, a new production run would take 4-8 weeks, and who knows if BFL will be making ASICs by then (or ever). It's just too uncertain for us to invest all that money and risk getting stuck with a bunch of units.

Hi,
I've been looking at this board, and must say I'm quite impressed of the "cleanness" and quality of your design. I'd like to get one for FPGA experiments, but that would require the accompanying VHDL/Verilog code to program it with. Do you have it available somewhere? (What experiments have you done with it?) Or perhaps I have misunderstood, and it is not possible to re-program these FPGAs while on board?
In addition it seem that you do not deliver outside the US?

Anyway, don't worry about the ASICs, they will not be able to deliver anything in the next 4-8 weeks. BFL has shoot themselves in the foot by poor design choice and need to redesign. This has cost them dearly, and we can question if they can even afford to continue this project, without mining for themselves first. Which is probably what they are doing right now, if anything. Also, the majority of people doesn't wanna dump 1500+ USD to an overpriced ASIC, they just wanna try the technology out of curiosity, which is where your board is perfect.

How about selling the FPGA design + code?  Then folks could "roll their own".

Yup...

Why not open source it... let the community pool it's resources and get these going.

Yes, I think this is a good idea and have been planning to talk with the others about it for a while now. Been too busy lately even to send around an email, so I certainly haven't looked at OSHW licenses and tried to figure all that out. Any experts on that stuff around here?

Turning money into heat since 2011.

If selling boards is lucrative enough,  maybe consider releasing or selling alternate bitstreams to keep sales alive. Don't throw out the existing work, just because the Bitcoin mining market shifted towards ASICS.  There is a market for raw hashing power, hash cracking, rainbow table generation, crypto acceleration, etc.

I'd definitely buy some

Me too... but they stopped selling because "Due to decreased demand, ..."

They should start selling these again.

Does anyone have an issue with bitmit where they can't bid on these? I'm interested in a couple

You can't bid because the listing is long since ended.  I wish bitmit made it more clear.

I'm looking to buy too.  PM me if you've got some to sell.  I pay premium prices.

Yeah, I would like to expand mine a bit, maybe 1 or 2.
