Creators! Feel free to tip me off about your keyboard related projects to bring them to 150K readers.
Jbam9 aka Comfortable-Seat-470 shared the case of JB69, this handwired ortho built around a Teensy 4.0. The case is printed in four pieces, making it suitable for printers with print beds of only 220mm x 220mm.
I give you: JB69. It’s a handwired, 69 key ortho layout with RGB, a knob, and a solenoid. Running on custom C++ firmware on a Teensy 4.0 – Jbam9.
The board uses a simple transistor circuit to power the solenoid directly via USB power, and the encoder controls the RGB brightness.
With regards to typing speed vs solenoid behavior:
Right now it takes 20ms to activate and deactivate the solenoid, so you can do up to 3000 characters a min or about 600 wpm without missing a solenoid click. In the event that the solenoid doesn’t have time to activate, the keystroke is still sent – Jbam9.
