Hacking a Poundland solar light with intriguing design fault

The choice of Poundland lights has been disappointing this year so far. That's not surprising, given the logistics problems caused by the pandemic.

This is a light they've had for a few years, but the style has evolved from time to time. It's very effective, especially with the neat bit of bubbled plastic light-guide.
The circuitry has the extra components required to use a colour changing LED, although it runs the LED at such a low current that the lower voltage red LED tends to dominate colours that include red. (magenta, yellow and white)

It's actually worth getting these just for the PCB to fix other lights. But you can also hack these to make them single colour, two different colour LEDs wired in series, or add an LED socket as in this video.

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