The MkI uses only passive components ( OpAmps, comparators and a Mosfet driver )
The MkII uses a PIC ( 12F675 ) and a motor driver chip ( L293D )
No control via PC, but only requires one hand and one potentiometer when at the EP.

Hi Andrew,

Cool, good location in the fork arm. Once I pictured in my head how the potentiometer functions, as in use, I like it, actually might add that feature to mine as I can velcro the controller on the ETX fork, and have a pot as the extension.

Cheers,
Damien
