Minimalist flame effect solar light (with schematic)

Although very minimalist, this design shows what can be achieved with a small microcontroller and a smattering of LEDs on a thin PCB.
An interesting twist would be to integrate a randomiser into the software so that there was no specific pattern to the flame. It could also allow the choice of a soft or strong flame effect.

Not sure who makes the AatLB chip. But I'd guess you could use a standard YX solar light chip in its place.

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.
