    you need a flashcard for the GBA SP. A Flashcard is an programmable cartridge where you can put one or more rom images. You can find all the informations here:

    Before you got a flash card you can play with the rom using an emulator.

    Where did you get the Gameboy drum machine thing? by the way this is really sweet... I'm looking at real moog theremins on musicansfriend. $350!!

    How did you get the drum thing onto your sp? please reply! please, please, please, please, please...

    the audile software is a free rom image. You need to buy a flash card to put the rom image in.

    Hi, thanks. I started with the Christofer Optical Theremin here:

    RS Optical Theremin

    and then I've tried various photoresistors/photodiode. I've tried both ultrabright leds and IR ones to beam the optical sensors.

    Finally I've added this filter to make the sound smoother and a simple transistor based amp to make it louder:

    That's awesome, but same here, I would like to know more about how you did it, I could probably do this for my friend, it looks neat. :-)

    That was cool. Obviously it's not going to be on my top 20 music list anytime soon, but the concept is certainly there. Nice one
