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.
