Step 6Testing
Mount a small pcb on top of the platform for testing Solder some rectifier diodes onto the pcb, add a capacitor a white led and a resistor. The video shows the test run and demonstrates the adjustment of the motor speed to get a good, non flickering display.
Tests showed that the construction generates about 7V easily. That should be enough to feed the pov circuit.
The motor is rather loud during testing. The reason for that is that the parts on the pcb are not mounted exactly and that the whole construction is out of balance and vibrating. After mounting the pov circuit this need to be fine tuned. An other source for unwanted noise is that I did not glue the motor exact and that some insulating plastics are sliding on the wall of the disc. I need to remove the plate ones more and cut the plastic of.
