HackSpace Magazine Issue 31 – BLE Keyboard Synthesizer #Feather #CircuitPlaygroundExpress #CircuitPython @HackSpaceMag @BlitzCitydiy

The new HackSpace Magazine Issue 31 features a synthesizer project by Liz Clark.

This right here is a BLE (Bluetooth Low Energy) synthesiser connecting to a speaker over the magic of BLE. According to its maker, Liz Clark (who you can hear more from in the issue), this is “the cutest keyboard ever to exist”. The keys are shorter and squishier than normal, which gives the
whole project a nice accessible feel.

The electronics are pretty simple too: powering the circuit on the keyboard there’s a Feather nRF52840, which communicates over BLE with an Adafruit Circuit Playground Bluetooth, plus an Adafruit STEMMA Speaker (it’s got an amplifier built-in) in the speaker. Aside from a battery, perfboard, jumper leads, and a handful of momentary switches, that’s the entire bill of materials.
