any ideas on where to get or how to make a torque based switch?
Im wanting to make a motorised target changing rig that will need to stop against a back stop a set distance away from the shooter. i want to make the rig self contained (i.e. no additional switches etc. down range) so that different distances can be used. the only way i can think to do this is to use a switch that stops the motor when a certain torque is reached.
any other ideas on how to do this are very welcome
