Luckily we never had to get to reflow-ovens level, wasn't that kind of maintenance.
I didn't mind fine pitch ICs, my hands were steadier then...

I do remember when magnetic core memory board in one of the studio lighting equipment was updated by a ...RAM CHIP!
It looked quite lonely sat in the middle of an 8" square circuit board. Whish I'd kept the magnetic core board.

Good grief, there is a sales brochure for it.

Those look cool. Some of the kits are quite expensive as well.

Are Nixie tubes the same as vacuum tubes?

Note that servos draw considerable power, so if you need to drive more than one or two, you'll probably need to power them from a separate supply

Yes, they are expensive. I'll buy one or two a year and that about it. Running out of novelties now, so this could be the last for awhile.

Re Nixies, I don't really know much about them except they need 180V.
Wiki says its not a thermionic device, so not a vacuum tube in the Marconi sense.

We used a lot of them as "station-clock" where I worked, some early time-code edit suites also used them before 7-segment LED came out.

They have a dangerous side-effect. If you stare too long at them you start to see the individual digits move back and forth. Bit like staring at windscreen wipers to see if they are flipping over...
