How I Designed This

I've always wanted to play Tempest the way it should be played in the 1980's, with a spinny disk!

Now I can with minimal hardware modifications.

Replacement Paddle Controller Wheel model made by jtritell's was modified to accept a magnet instead of a potentiometer.

Other changes were made for cosmetic purposes:

Hexagonal supports (because I wanted to)
Fillets on top part of knob (for comfort)

Shame on jtritell for not commenting their code!
