[sdiy] I finally did some SDIY this weekend

[The Peasant]

I was planning on using a slide or rotary pot, and to derive the velocity and 
acceleration (or maybe just velocity) electronically, but I'm concerned about 
pot wear. An optical encoder (and I already have a few) would solve the wear 
problem but would add circuit complexity. Guitar pedals seem to do OK with 
pots, but I think a hit-hat pedal will get much more use in a short period of 
time.

I think I will experiment with some better quality pots and check wear rates. 
Does anybody know if cermet pots wear better than carbon?

Take care,
Doug
