What do you see this actually achieving? You make an ASIC for very specific reasons; FPGAs already do a great job of bridging the gap, including in production. For example many budget oscilloscopes these days run with a microprocessor-FPGA pair.
As for an scrypt ASIC, I don't believe you could just whip one up over a weekend. I don't know how the scrypt ASIC nut was eventually cracked, but the algorithm was specifically chosen to be hard to make an ASIC for. It requires fast memory and lots of it. If you make yourself a massively parallel ASIC and bolt it onto some GDDR5... that starts to look a lot like a GPU.
- wmf 12y agoscrypt was intended to be memory-hard but it failed somewhat. There is a time-memory trade off that significantly reduces the amount of memory needed. Then the altcoin people also used scrypt wrong, setting a memory size of 128 KB which is trivial to include in an ASIC.
