The NoiseAXE is a miniature synthesizer based on the Picaxe 08M microcontroller. Its operating principle is fairly simple: a conductive stylus touches the leg of one of eight resistors to play one of eight notes, while a photoresistor controls the amount of modulation, creating a variable vibrato effect. While the synthesizer’s output is rather limited (the NoiseAXE isn’t exactly a Yamaha DX7), it’s still a pretty cool little project; you could use its unique sounds to add that gritty analog touch to your next electro hit. Check out the video clip below to see and hear it in action.

If you hooked the touch leg upto infrared reciever diodes or the like you could make it convert the IR in a room to sound..
arrange the IR diodes in a circle facing out.. so they dont all go off the same..
doing that, adding rotation may make an interesting effect…
one more..
hook it up to the multi axis on a game controller and make it very annoying to play games..
i have got to leave this thing along.. but
10 more of them, some switches, and fine tuning and you could make a piano.. or mod a piano..
Amazing Site I like it. It Was Quite Interesting NiceWork I appreciate the information you provided Excellent post. Keep it up! Good day!
sinus… for gods sake add some sinus… squarewaves make my ears bleed.
This project does not produce a nice sin only because its a low part-count project, pity, because an inductor and a 220nF with 4.7KOhm would have improved the sound. Gonna try build my own one next week :-)
besides the IR part that was basically my midterm in high school electronics (except on a protoboard to save money)
This could be an interesting addition to my circuit bent electronic guitar.
Great, a collection of circuit bent instruments to complement my collection of smallish robots! :D
