Digital Fidget Spinner Motor

Beavis3215

The first time I saw a fidget spinner, I thought that it was crying out to become a motor. It uses two hall sensors, an electromagnet and a Propeller Flip. The hall sensor at 3 o'clock turns the electromagnet on. the sensor at 8 o'clock starts the magnet off sequence. There is a delay after magnet off, before the magnet actually turns off. The delay is manually controlled by the two pushbuttons in the upper right hand corner. Delay can be varied between 0 and 63 milliseconds. The current delay is shown in binary on the 6 LED's. Maximum speed so far is about 1100 RPM using a delay of 8 ms.

Funny question, but how do I post a video? I barely had the data allotment for this photo.

Now just convert it into a perpetual motion unity gain motor!

It does run at a very consistent speed from start to battery depletion, which ususlly lasts an hour and a half.

I got a better Spinner with ceramic bearings. I upgraded the bracket that holds the magnet. I am now up to 2400 RPM with an unmodified fidget spinner.
