Making progress on my stepper motor work, have done mock up, it is pretty dodgey because I am mocking it up with tape and glue. It works well though and does what I want. It is a sound work, I just need to figure out permanent fixtures as it tends to fall apart which isn’t surprising, good concept. I am thinking about using perspex to mount it, it is still a while till I complete it. I just need to be patient.
