(Persistence of Vision)
POV as you type (a typewriter way to write on a POV unit in real time).
A real time way to send characters and write on a Persistence of Vision unit.

Type in a computer keyboard, and send the characters via RF 433 Mhz to the POV unit, in real time.

I used a Hall Effect Sensor for stabilization as well creating a starting point for the writing position.
