NoiseAXE Minisynth


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.

  1. 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…

  2. 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 :-)
