What's to figure....
  • The moisture protected pcb
  • Has a hall magnet sensor for sync
  • Two batteries = 6VDC
  • An smt LED
  • A smt 8 pin micro processor
  • Simple software that detects passing a magnet and records the duration to the next passing that gives it rotary speed then it lights the LED in three calculated speed relative synchronized time periods.
  • Two or more per wheel give dynamic balance and better POV at lower RPM.
Do you want a circuit diagram or what ?

If we riff on the theme: use the spokes and a proximity sensor (use a hall, and a magnet next to each other, the spoke takes the field away...

This improves the sync.
