PsyLink is experimental hardware for reading muscle signals and using them to e.g. control the computer, recognize gestures, play video games, or simulate a keyboard. PsyLink is open source, sEMG-based, neural-network-powered, and can be obtained here.

2021-04-03: The Idea
❬2021-04-03❭
The Idea
On this day, I got the idea and started researching EMG design and signal processing, motor neurology basics, as well as existing projects.
Soon I realized that I will need a microcontroller to record and process the signals. I considered the Raspberry Pi Pico and Arduino Nano 33 BLE Sense, and chose the Arduino because:
- Bluetooth
- More analog-to-digital converter inputs
- TensorFlow Lite support, which would allow me to leverage neural networks for signal processing. This is a bit of a stretch, can't wait to get disappointed by this :)
I wish there was a decent battery/UPS shield, couldn't find one so far.
