We couldn’t wait to get our hands on the new HalloWing M0 Express from Adafruit. Based on the Feather M0 Express microcontroller, the HalloWing comes packed with on-board features like a 1.44” full-color TFT display, accelerometer, light sensor, speaker driver, and JST ports for connecting NeoPixel strips, sensor inputs, and more. All of this, plus a built-in on-off switch, means the HalloWing is just asking to be put into a wearable project – that’s what we did. Behold the Handy Sampler: a wearable audio sampler glove!
Our glove is more of a sampler than a synth: you can record your own sounds and load them into the 8MB of SPI flash on the HalloWing. We added capacitive touch sensors to the tips of the fingers for triggering each sound. Just press your thumb and finger together to trigger one of four pre-recorded sounds. And the TFT display shows your awesome synth-pop band logo, or a picture of your cat, or anything else you can fit into a 128×128 pixel BMP image.
This project is easily coded using CircuitPython, the “edit in a text editor, drop the file on the flash drive and it runs automagically” language.
