An AA (Automobile Association) light that was sent by Robert for our exploration.

The circuitry is minimalist and interesting, the LED mounting and reflector are good, but the battery itself is a bit lacklustre, and the intensity rapidly declines with battery voltage. The choice of a lead-acid battery is odd. If I was being cynical I might ponder whether this was China's way of getting rid of its "toxic" metals.

Still lots of scope for hacking and customisation though.

This is also the video where I realised that the word "PISH" is very "Glasgow". To quote:-
"Pish. Translation: Urine. However, in Glasgow and other parts of Scotland, it's a common word for something that evokes a negative vibe."

This light is "Complete and utter PISH!"

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.
