Wireless Joystick

I'm on chapter 7 of the Prop Ed kit now

For my 'lab' I decided to hack a joystick and connect to its potentiometers directly with the Propeller. Unfortunately, this joystick has horrible potentiometers! So the project is stopping right here...

How big are the pots?

I'm hoping to make a magnetic encoder board small enough to take the place of a pot in a servo; maybe the PCB will be small enough to take the place of your pots.

Besides mounting the encoder PCBs you'd also need to mount a magnet to whatever is rotating.

They're small, like the ones inside the continuous rotation servos. It should work, I've been following your post on it and also looking for something like that for a long time.
