This camera is designed by Qhy who I think also designed a number of CCD cameras sold by some well known companies. Issue is have seen very images taken with this and the few on Qhy's site are nothing to write home about.
Qhy has also got a parallel port version out I seem to recall

You can email him and he will respond and answer all your questions..he also has a forum where people post images but the language is Chinese so thats a bit of a problem (at least for me!)
I thought long and hard about getting it -you can buy direct from him..but in in the end wussed out. I will revisit this decision sometime in the future..by which time he will probably have a 6 mega pixel version out
