Inside an Aldi solar security light.

A look inside a very streamlined solar security light. This lithium cell powered light has much less circuitry inside than I was expecting. I think the chip may be a microcontroller with the PIR sensor being monitored by a simple analogue input.

My apologies for the state of my hands. I very occasionally get a recurrence of dyshidrotic eczema and it makes my hands look a bit rough for a while.
I think it might be a sympathetic reaction to skin damage on my feet caused by wearing industrial footwear in very hot weather. When you have feet my size there's not much choice in work shoes.

Dyshidrotic eczema (pompholyx) has no known cause or remedy. It's a harmless but annoying issue that causes a flare up of tiny water blisters on your fingers, and sometimes the sides of your feet too. It tends to be triggered by heat and may be an exaggerated immune system response to external factors like heat and airborne pollen/spores.

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