Selling the Bastl OMSynth Mini Lab v3 (circuit development and performance interface, more info here: bastl-instruments.com/instruments/omsynth) because I have not been using it enough. It has worked the last time I played with it normally and have kept it in a safe place in between. I am also adding along a set of additional basic electronic components including resistors, capacitors, LEDs, photoresistors, integrated circuit and jumper wires, so you have more options playing with it.
