thanks guys, at the moment it is still a work in progress, i want to convert one of the transistors to a reed relay so i can switch isolated circuits.

but maybe there will be a guide, or i might build them and sell them depending on how well they work in the end.

i'm actually laying out a simple trigger input board that will allow for NPN and PNP triggering. which you can use to trigger most things via a transistor switch. or you can use it in circuit with a relay if need be.

If you want i can send you a few once i get the pcb's made.  just let me know.

i would be interested in knowing more about how that works, it sounds interesting

here are a few ideas of what it will be able to do when its finished:

this is the pitch sync, one gameboy controls the pitch of another

this is audio sync, one gameboy controls the audio output of another

this is self sync, one gameboy controls its own audio output

there is a lot more to come and i hope to build a full waveform editor into it so that i can get some really weird sounds out of it smile
