Telescope mount controller: OnStep 6 deg/sec slew speed on Vixen SP loaded with Askar FRA500.

Testing of the OnStep telescope mount controller. This implementation is the MiniPCB2 with Teensy 4 and TMC5160 drivers. It makes this 40 years old mount a GOTO mount with pretty fast slew speeds. I also built the Smart Hand Controller which is handy. In the video the OnStep is powered by a 12V battery.
