Make Annoying Sounds on the Go with This Synthesizer Wristwatch
Clem Mayer's user-programmable wristwatch synth runs on an Arduino MKR WiFi 1010.
Back in 2016, Clem Mayer built a very annoying synthesizer that acted as an Atari Punk console and light theremin in the form of a wristwatch. Unfortunately, it broke at a Maker Faire, so he decided to rebuild it to be “better, louder, and more annoying than ever before!” Like many (all?) personal synths of this type, the sound would certainly be maddening to onlookers, but it’s reportedly quite fun to play yourself, and easy to program.
The wearable device uses an Arduino MKR WiFi 1010 as the heart of the project, chosen over the Micro in order to take advantage of its onboard LiPo charging abilities. While not used here, this also gives it WiFi capabilities as a bonus, which would present all kinds of possibilities if configured properly.
As it’s used now, the portable synth can produce a random start pattern when it boots up, then allows the wearer to program in a certain “tune” for playback. This can then be modified live as it plays back, using a trio of slider potentiometers to vary note properties and toggle switches to activate each note in the sequence. LEDs are provided for feedback as well.
The unit is built on a 3D-printed body, along with a laser-cut face and back plate. It’s a bit bulkier than Mayer expected, but it is self-contained, and should survive many Maker Faires to come!
