Ribbon controllers (Was: Re: [sdiy] DIY slide-bars)

[adam]

The original was just the nichrome wound around the non conductive core suspended over a piece of sheet steel. Current source on the string pickup the voltage on the steel. Seems like it would be strong and durrable, last a good deal of time. maybe i am missing something here though, but hell, it was good enough for Oskar Sala
