This past week I worked on the second instrument for NIME. After observing the effect that the DC motor had on the guitar pickups, I decided to incorporate that in this second prototype. So, for this one I didn’t use any strings to produce sound. By altering the speed of the motors I realised the […]

homemade hardware : 2-3

Last week’s circuit turned into an schematic on Eagle. And the homemade Arduino bootloader shield! I got the wrong crystal oscillator though, will change it as soon as possible.

The idea, back then, was to come up with what I perceived as a “rhizomatic instrument”, that would have various points all connecting with […]
