110 wireless LEDs in ONE coil

If it's worth doing it's worth doing with excess. Having bought 100 of the wireless LEDs before discovering that the exciter coil already came with some, I got the urge to see if I could get them all to light at once.

Note that some of the LEDs are hacked. It's the ones with double LEDs if you can spot them. I removed the tiny PCB and soldered two LEDs in inverse parallel directly to the inductor.

The ambient current of the unloaded coil was 80mA. With 110 LEDs in it the current went up to 200mA.

There's a longer video showing the circuitry and some oscilloscope waveforms here:-
