Hey Maho, could you answer two things for me?
Overall, I think your stick is gorgeous, your terminal work is very nice, and your wiring is very direct & well-managed (I wouldn't have used all one color, but that's just me).
1 - What stick are you using? Is that the Perfect 360?
2 - I don't recognize the PCB you've used, much less do I recognize your output terminal. It looks like a 9-pin serial, but what manner of console do you hook up to? Are you not-so-secretly an experienced circuit designer?
I only ask because I'm still in the planning stages of making a totally universal adapter, and I think that, honestly, USB 2.0 might be the best primary output. After seeing your work, I was thinking that with just a dummy digital port, I could hook into just about any other console end (with a properly programmed PCB in-line, of course). IDK... it all started when I saw the absolutely detestable quality of the only available PS2>SAT adapter.
Anyway, sorry for the wall... Any help/info would be greatly appreciated!
