sync thing in a gameboy (self pitch sync 2)
this is a gameboy i built for a customer, i was a be reluctant to build it as it uses my sync thing which isn't fully developed yet. but the results were better than i had expected. this video shows how the system can be set so that it can be used as a regular pitch bent gameboy.
the gameboy was very difficult to build, i was designing it as i built it because the sync thing wasn't finished yet and so i had to add bits as i built it to make it work and i was running out of room. in the end i had to loose the headphone jack and internal speaker
