membrane potentiometers?

These would act as some sort of ribbon controller! Could be good for those wanting a Fuzz Probe workalike or something of equally eccentric nature but avoids that nasty EMF!

I'd seriously consider attaching one or 2 of these to the body of a guitar, possibly wiring them to control tone or volume, or better yet to give it a seperate jack out and let it act as a form of expression pedal!

What about using a flex sensor?

damn.. that looks great! do they work the same? price is even lower

thanks for the link!

Maximum resistance: 30k ohms to 40k ohms, proportional to the degree of flexing or bending
Nominal resistance: 10k ohms
Applications: virtual reality data gloves, robotic, bio-metric, physics and engineering (that sounds about right) 
Length: 4.5"

also, if you have any conductive foam from past ic purchases and some tin foil or whatever laying around for a sandwich it's worth playing with for a quick and dirty variable resistance input to filter/noise circuits. check foam with multimeter for proxmity and compression variances. maybe mount in a door hinge for foot control? (you could vary resistance between hinged contacts with layers of foam, replace/dispose of 'spent foam' layers, etc...)

nice one!
