Description
Build a "Not A Typewriter" with I2C Solenoid Driver and Adafruit Feather RP2040 running CircuitPython code. This device is designed to give your modern computer keyboard the essence of a vintage typewriter.
The 3D printed case is designed to look like a classic typewriter and features a real service bell. It has two mini solenoids, one to emulate the loud clack of the typebars, and the other to triumphantly announce the ding of the carriage return.
Designed by Noe Ruiz for Adafruit Industries
