Talk:TISSEOT

Can I ask why you chose a wheel? Cause, if I understand it correctly, you're not making the 'steering' wheel, but the 'full|half|slow' thing, right ? That is afaik not a wheel, but a handle that moves around a 'solid' circle, totally not like a wheel.
For that part you're better off choosing some sort of cylindrical body, like um, maybe a paint can, food container, anything but a wheel. The handle is harder obviously, for the right look it'd have to be copper/brass. I'm sure browsing through a market in the box of old 'hang- en sluitwerk' you'll find suitable stuff tho. Pity the Waterlooplein market is not what it once was...

The 'stops' might be made by utilizing and old electrical rotary switch, they had notches like that. checking space state with an arduino is simple enough; use a led and photodiode that counts slots in a slotted disc. If you need 100% certainty in which position it is (instead of relative) deploy a pair of leds and photodiodes and encode the slots binary like slot 1 __XX and slot 2 _X_X, that way you have 4 positions. With 3 pairs you have eight.
