Wow, Gijs’ mechanical circuit-bent Casio is starting to resemble an amusement park ride. Nice use of a motor/drag contact for sound, and apparently this instrument does more than just that –
It has also got a video out, The video out is basically just the signals from the patch bay going throe a 1k resistor and a diode.. i dont know if this is necessary.. but seemed right.. video signal is around 1 volts and the pins from the casio chip are 5.. so its a bit dangerous (maybe.. maybe-not).. My equipment has not broken jet..
