Here's my entry video.
A harmonic resonance device that uses piezoelectric ceramic elements to both drive the vibration and harness any excess energy produced.

Ohhh I might have to get back in the game.  My 3D printers are in storage though.  It might have to be some old school scrap yard conglomeration.
Maybe a new Rodin-ish coil variation that has a strange construction method.  Probably of a less efficient, more power, end of the spectrum.  If it don't fall apart, I'll send it to Russ to hook to his cap bank. Lol

That's the spirit Nate.  Melted parts, smoke and pieces bouncing off of car doors is all good.   :-D

Hello everyone,
Thanks for the motivation Russ!  It's been over 2 years since I've posted anything publicly on youtube... the 2016 pmbo.  I've had this idea since then.  Here's a peek at this years entry.


This is a solar or externally powered pulse motor.  It can be run with either the fidget spinner or the acrylic as the rotor.  The spinner is powered by  solar panels when it is the rotor.  The acrylic rotor must be supplied by another source (battery, p.s., solar etc.) since the spinner will be the base and consequently the solar panels will be facing down.  The spinner came with 3 leds that flash patterns.  They will serve as the feet of the acrylic piece.  Disco time.  It will be clearer next video.  Promise. ;)

Parts and supplies:
fidget spinner rotor
3 coils (solar dancer)
modified dadhav circuit
acrylic base
3 neo magnets
nylon bolt, washers and nut
2 transistors mpsa18, 2n3906
500k variable resistor
300k fixed resistor
100uf cap (solar dancer)
6 solar panels (solar dancer)
headers/connectors + jumper
crazy glue
electrical tape

ive had my first project spring an oil leak and my second fall through so im cobbling a few things together to make something spin. just for fun, a little self-torture via 24 strand secondary. (yes russ, i know you are doing 200....that insane!) some crazy stuff happened during this build so far.

'trigger' and 'run' coils, showing off their nice shape. this was the only coil i had that displayed a proper clean sine wave on this magnet wheel. all others were full of 'W's and 'M's
