Wouldn't it be nice to be able to buy mining hardware on demand, and not have to wait months? I play tennis with an investment banker who's interest has been perked by Bitcoin.
So first I need to figure out how much it will cost to develope the hardware. If some experts could provide me with some details so that I can provide them to the board designers, that would be great. None of you happen to have a Gerber file for an ASIC miner by any chance, do you?
The boards are the easy part. Any decent college kid can do those.
What you will not be able to easily acquire are the ASIC chips themselves. You're looking at a multi-million dollar project (and at least 12 months) to design a chip to be competitive with what will be out there in that time frame. If it was as easy as you think it is, there would be 20 or more companies selling them already.
