Wearable synth plays programmed or random tunes

Unless you’re very good, personal synths are fun for you — though often quite annoying for onlookers. After making his own wristwatch-based synth in 2016, Clem Mayer decided to build a new version that’s larger and louder than ever, and programmable via an Arduino controller.

Mayer chose the MKR WiFi 1010 here to take advantage of its LiPo charging abilities. This enables the device to be entirely self-contained in its custom housing, with a variety of switches and sliders for an interface. 

Users can program their own “tune” to be played back, or even take advantage of a random sequence generated on startup, then modify the sound as it plays live.
