Inside a hover ball
🕑 Added 2024-09-01 03:19:36 +0000 UTCSomething refreshingly simple for a change. It's a ball themed puck that glides on a bed of air created by an internal fan.
The construction is very simple, but it still manages to squeeze in a PCB, albeit purely for marshaling power to the LEDs.

Ah of course. I should have realised that by now. Thanks.

Not significantly. The internal MOSFETs of the LED drive chip will have some resistance to limit the current.

Will the PTc thermistor provide some resistance for the LEDs?

this is so useless. I love it!

Turn it upside down and it's a roomba.
