Inside Lidl's Livarno solar light strip.

Quite an odd little thing. It's a solar powered strip of 180 LEDs that has a Xmas style controller for selecting various patterns on two channels of inverse polarity LEDs.
I'm guessing there may be corrosion reduction benefit from the continuous polarity reversal (less damaging that constant DC when water causes electrolysis damage)
The module has a generous solar panel and a decent 1000mAh NiMh cell.

If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:-

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