I made a magnet top you can spin to make electricity.
Does that count as tech?

Probably /diy/
But pretty cool, how quickly does the induction slow down the top?

depends on the circuit. A buzzer or a voltmeter doesn't seem to slow the spin at all, but led's reduce spin times from 4+ minutes down to 30 sec ~ 1 min depending on how aggressively I use the light.
