I'm amazed at the timing of this thread!
Just started doing some research on controlling the Z-1000 pot. I've alrady opened the Z and can contribute that the 3 buttons (red,yellow,white) are all simple pushbuttons connected with a common ground.
I had thought about buying an arduino-controlled pot to replace the existing rotary pot... just need to extend the 3 pot wires to an external pot.... But that's where I'm not sure what is required!
My design would be to have speed-up and speed-down buttons connected as inputs to the arduino and a digital pot to replace the rotary pot in the Z.
I should have measured the value of the pot while I had the Z open, but forgot! You have to unsolder the 3 pot wires to separate the boards to get to the PB pins on the circuit board.
Anxiously awaiting the next post. PROF, I'm hoping for a suggestion on an android controlled pot!
