Hi Nathan,
I really like your solution. I've seen a number of automated vales, but almost
all had the drawback that they could generate considerable stall load on the
motor. This solution appears to be much more efficient.

| Hello Nathan, Is there a technical reason you use a chain link between the motor and the differential grear? Would it be unsave to engage the gears directly in this case? With friendly greetings, M. Moolhuysen. (14 years ago, 11-Aug-10, to lugnet.technic)
