These things aren't just really nice to have for decorative purposes, but they have very interesting circuitry too. Literally a classic multivibrator with inductive coils.

The circuitry is ...

Another huge sack of AliExpress joy was awaiting me when I got back to the usual bench.
Let's dig in and see what tat I bought.
Although I made this video while in the work accommodation, I wanted to run some tests on the circuitry when I got back to my usual bench.
The heater passes 480mA at 3V and is run for 2.5 min...

A tour of the tool bag that I travel with and use on showbiz jobs.
I don't take this on planes. Just by normal public transport.
A look at a very standard snubber module from AliExpress that is used to help suppress arcing across switch/relay contacts and to protect triacs and prevent false triggering by snubbing fast transi...

This is a slightly naughty upload of the BBC coverage of the Edinburgh Tattoo, so the link may get taken down unexpectedly.
Trucks all loaded and the show run is complete. Aching and slightly exhausted, but had a great time working with colleagues that are such good friends that it doesn't feel like work.
Now to ...

The second day of loading out the show, and we're almost done. Just a few lights, some power cables to drop down into flight cases and two trucks to load with stuff.
We did a very worthwhile chunk of the load-out today. Everything in the castle and at the esplanade level.
Tomorrow (today) it's an early start (BOO!) and I expect to take down and box every...

Some more backstage stuff, including a rare glimpse of the lone piper from behind the scenes, and our new goods lift for getting our flight cases up to the technical level and gantries.
I was expecting this light to be more complex than the classic hot cathode ones, but it turned out to be simper. Given the higher voltage of the thin cold cathode tubes, I wonder how reliable this...

This is a bit of circuitry that I cobbled together a very long time ago. It's always useful to take a look at old designs to try and work out what I was thinking at the time, and also to see if im...

I made this just before coming across to work on the show. They always seem to be popular videos although the outcome is fairly predictable.
