I'm back in Glasgow at the moment, and thought I'd check out the Christmas lighting stuff in a big UK store called John Lewis.
Patreon seems to be having a moment with links, so you may have to follow this link directly.
Here's a quick look around the Department of Villainy tree. The DOV is a spoof of the government's department naming system. (Dept of Environment, Infrastructure etc.)

Just about done. Only the final bits of programming to do before it gets installed.

I'm thinking that these may be my favourite connector of all. Perhaps a bit big for most electronic applications, but for supplying power to electrical and electronic equipment they are ideal.
Super rugged, cheap, locking, water and dust resilient, impact resistant, great connection. ...

I've added some yellow squiggles to the tree (each with its own control channel) and changed the star to warm white.
Total current draw now around 5A at 11V.
Now I'm pondering adding a modified string of 225 warm white LEDs to the middle of the tree and maybe another 225 blue LEDs on ...

Lookin' good. I'm using a proper industrial grade Meanwell power supply, so I adjusted the voltage down to 11V to give the LEDs an easier life. It's still very bright though.
Current draw at 11V is 3.2A
Now to decide what I'm going to do with the other ten control channels...

It's a bit disturbing when something you use regularly fails in a manner that involves shorting out the internal lithium cell.

Who would have thought a $1 component from a fridge could be so much fun. This is a very interesting device that has the primary function of de-energising a compressor's start winding after a short delay. But it has loads of other applications.
Having seen the use of a non Newtonian gel as an impact absorber I decided to make some and then hit my hand with a hammer to test it.

A couple of useful things in this video. A way to test small cells to see if they have internal protection circuitry by shunting them with some low value resistors to trip the protection circuit deliberately.

I'm not sure what the worst feature of this inline dimmer is. The fact that it has to be soldered into circuit, or the fact that the triac can apparently be damaged by the wrong "type" of lamp.
