Motor Controller Test Assembly for MRV floats
I designed and printed this test fixture for the marine company MRV. It attaches the output of a gear motor to a 3/4 turn potentiometer. It features an easily replaceable break-away shaft coupler designed to fail before the gear motor breaks the potentiometer. This device was used by the MRV software team to program the controls for the fins on one of their new profiling floats.
