The pandemic has really limited choice of Poundland stuff on the Isle of Man. I got some of these lights to see if the design has evolved much over the years.

I've not got one of these lamps here yet, so I've done some computations based on the layout, voltage they were tested at and power that they dissipated.

Not just a reminder, but also another whisky distillation video using a posh one supplied by Ralfy. These are just a momentary clickbait distraction. Normal technical content will continue as always.

I'm not sure how I managed to refer to the 555 as a microcontroller during this video, but at least it'll encourage the pedants to leave strongly worded comments.

This smaller vehicle-version of a recent item I explored, has an unpotted high voltage section.
Perfect for further exploration.

This stuff has never been very impressive. It's a lossy fibre optic material that emits light along its length when illuminated at the end.

This is a teardown of a very simple early RCD/GFCI. So early that it was still called a current operated ELCB (Earth Leakage Circuit Breaker).
