Using HK X large retracts I wanted to electrically operate, I started with a microprocessor design with current limiting etc but it gets unnecessarily complex for a one off so I reverted to old fashioned switches. Took about half a day including making up the three micro switch mounts. Slightly larger gear motors are on order that will bring up the current to about 50mA. Still enough to get over 100 cycles per charge with a 3 gear system. Separate battery pack will not react with receiver power. The servo board will be a custom PCB with header sockets for each plug in leg. Scale speed without valves, compressors, tubing, and no leaks!.
