Nice to see you do the stepper motor trick Dave.
I used to do this in my early days as an IBM electronic repair engineer in the 80's.
Motors out of large printers worked exceptionally well and the driven motors even had a bit of torque.
Well, it kept me amused for a bit.
It is still amazing that most people I have told about this don't believe that it does actually work.
I can point them to this video... Excellent.
