Using retail or bulk-purchased components: Has anyone here developed any actual low cost do-it-yourself FPGA boards that have competitive or better-than competitive hash/$ rates?
If-so: Is that person willing to share or sell the design plan?
I've seen a few threads attempt to tackle this topic, but I have yet to see anything actually come from them. It seems the thread authors drop out or decide to develop the idea for their own use after some progress.
If not: Is anyone here willing to collaborate on developing such a board? And not just an FPGA board that will hash, it MUST be competitive in price...if this is even possible. It seems, so far, the best hash/$ rate is BFL's products. But if a board could be developed to be at least as good as the next best hash/$ rates, it might be worth it. Especially considering the slow product shipping time of Butterfly Labs.
