Some Random Thoughts About a Modulation Wheel

I just wanted to share this idea that popped into my head recently. Why not make a modulation wheel using an LED and a Cadmium Sulfide cell like this. This is rather crude but it is only meant to give you the idea. You could use the changing resistance of the cell in your circuit to provide a control voltage. No pot to wear out. One of these days I plan to flesh this out with dimensions and a schematic and build it but hey get creative this has some cool possibilities.

The whole thing would reside under a panel and you would need to make it dark inside with felt or cardboard The top of the wheel would stick up so you could manipulate it.
