For those of you with a 3D printer you can make one of these coasters from the tight little script (with my first use of a loop) in the description of the video on YouTube.

My brother Ralfy's old electric shower failed with a bang and lots of water spraying everywhere.
Let's take it to bits.

The idea of having a tiny washing machine agitator for a sink or bucket might be appealing for those who travel. But it's not really a great thing for bear sized clothing.

This video will be Patreon and selected friends only, as it's just a progress video and has me slightly perplexed.

It's a while since I've taken a plumbing component to bits, so here's a lockable outdoor tap / faucet with an interesting ceramic water gating insert.

One of the perils of cheap prototype PCBs is that you can make inappropriate ones.
I've just ordered a very small batch of five of the above circuit boards.
There will definitely be a build video when they arrive.

There's something just a little bit suspicious about this high profile air cleaning system. Lots of marketing hype and "molecular science" that could only be proven by a very skilled lab with a large budget.

Let me know if I'm doing too many UV videos. I'm always aware that if I do too many on the same thing it can result in subject-fatigue for you guys.

Uh-oh. I've done it again, and filmed a bit that wasn't supposed to be filmed. The extra bit is me checking out the differences between the schematic and actual implementation.
