[sdiy] Touch Controllers

[Scott Evans, Gen Mgr]

Hello all,

After reading the interest in the ribbon controller ideas, I got to 
thinking about touch controlled interfaces such as the Buchla 100 and 
200 interfaces as well as the Serge TKB. I had opportunity to use the 
Buchla 100 controllers years ago, but I have never seen inside one of 
these fun devices. Has anyone in the DIY community done any development 
on these? Or perhaps some information on how the mechanics work? I 
believe these are variable capacitance devices. I would love to build 
something of this nature. Any guidance would be appreciated.
