In case you'd consider the motorised fader, there's an Arduino
project using it:
There's one problem with this: the author has the H-bridge
'enable' pin hardwired. This means that the motor always
sees a low-impedance voltage source. The voltage can be
zero, but that will make the motor resist movement.
When the fader is 'touched', the motor should be open-circuit,
so the H-bridge should be disabled, this takes one more pin on
You could actually control the 'resistance' of the fader
by pulse-width modulating the enable pins of the bridge.
To control many faders you'd need some external logic to
multiplex the Arduino's logic pins, but otherwise everything
A world of exhaustive, reliable metadata would be an utopia.
It's also a pipe-dream, founded on self-delusion, nerd hubris
and hysterically inflated market opportunities. (Cory Doctorow)
