This keyboard uses the arrow and glass pane hitbox glitch to transfer a 5-bit signal wirelessly. I took inspiration from test137E29's enderporter controller which transmitts 1 bit at a time, I extended to transmit 5 bit simultaneously, and this can be extended to 8 bits if more characters are needed.

There is a reset mechanism to stop it picking up random signals if othing is recieved for ~4 seconds.
Most of the space is taken up by the decoder and bitmap for each symbol, I made it myself, but anyone is welcome to use this with their decoder.

This is just a proof of concept, i don't think i will continue to work on it, but anyone is welcome to modify this design.
