I am scared of the outcome as such. Having had a deep technical discussion on the witch computer and written a python virtual machine which is similar to it, I propose that I may end up with several hundred dekatrons and a large electricity bill if I buy one :)

A1: you would soon sell it to get a Ge transistor serial machine, e.g. an Elliott 803 in the next room to the Witch. (And then regret and make/buy another dekatron machine)

A2: I'll buy you one dekatron, if others chip in.

A3: ah, youngsters. No self-control.

Don't even start me on A1. I already have a copy of this downloaded and enough transistors stashed to build it! http://www.smrcc.org.uk/members/g4ugm/Manuals/wirelessworldcomputer.pdf

As for A2, just no. don't even go there :)

A3 working on it as I get older :)

Talking of cats, my neighbour’s cat had to be put down the other day after it lost a fight with a bushy tailed rat. I had to hold back the tears of joy when she told me she’s not getting another one  :-DD

Those tree rats can defend themselves. I've talked to an owner whose dog's eyeball had been scratched by one.

My daughter's dog is a superb rat/mouse detector - as proven in two houses and one shop :) Despite its belly only being about 4" off the ground, its peak pursuit speed is 24mph (as measured by a GPS receiver I strapped to its back).

It loves tree rats, but hasn't quite caught one yet. There is a suspicion that it really likes the chase, and has pulled its punches teeth at the last second.

Yes we had a Jack Russel. Tiny thing. Just had to take it up to the local stable and say "rats" and it was off like a torpedo and would return with the mangled carcass of one. Rinse, repeat with the odd interlude for water and it'd get quite a few in a day.  It was much more fun shooting the rats with a shotgun though - still got a couple of scars on my leg from some shot that bounced off a fence  :-DD

We're engineers here. Disposing of rats should have some mechanical or electrical properties at the very least :)

I propose microwave oven transformer, chicken wire and some beers  :-DD

If you're going to use microwave parts, you may as well make use of the Magnetron, not just the transformer. :)

The problem with that philosophy is that it eventually, inevitably ends up with "Got Honey Badgers? Get an infantry battalion, an artillery regiment and the sappers.".

Come on, that thing really doesn't launch that far away and not with a lot of force, plus squirrels are very agile. He didn't suffer a lot. I was expecting a lot more force... :-DD

I was intending to give you an update on how my work is totally taking care of the problem how to spend my time and energy, and report on how some people at work 'pulled a Elsie the Cow' (die Kuh Elsa) on me
....
And then OUR legal beagles start to play games over the signing of a NDA which would be a prerequisite to getting the abovementioned manufacturer to talk shop with me.
It is not that I need to dig to discover more related dung - it seems to be sufficient to stand near the shovel.

Someone had a short fuse? Got an open one to replace ...

Looks like typical phase fuse on a bus bar. 630A is about right.

Half of you...? THAT MUCH...? Oh my... you have mellowed a bit during your time away from our little nuthouse...  >:D

If you skip to 2:00 or so and do some PAUSE/PLAY abuse with the [SPACEBAR] you can see the moment of launch, then a frame where Rocket J. Squirrel seems to look right back at the camera, then some pretty impressive real-time organic computer PID loop operations and tail-powered moment-angle attitude control before it lands on its feet & scampers away. :-+

I suspect if given a few more iterations, that squirrel will either develop a healthy distrust of white plastic cookware or an unhealthy addiction to being flung.  :-DD

VFD (approx. child's coffin size) failure testing ... Can't provide more, videos and blown up DUTs  would look quite interesting.

This module wasn't blown in that test, this one is just a tiny little bit damaged in comparison.

Oooh, semipacks... I don't miss having to replace those. Talk about the mess! Thermal paste everywhere, especially in places where you don't expect, and don't find until you see a blob on your sandwich...
Did you ever find one that the fuse had protected when it blew? I never did   :-DD

Also, I'll see your 630A and raise you this beastie:


One of a set of 3 (still intact) I keep meaning to put on fleabay and forgetting.   :-\
The font colour I use is an affectation that I make no apology for

Impressive. My personal record is 315A, but that was three of them. And, we also triggered the 1250A circuit breaker that sat upstream. The EE surveying the problem (which turned out to be a busbar short on the load side of an UPS that the UPS compensated for by going into internal bypass and frying its solid state relays and the upstream fuses) muttered something about "improper selectivity" and reprogrammed the circuit breaker to be a tad slower to trig.

A problem that plagues three-phase systems, especially temporary ones, is the tendency to connect the big load on phase one, a boom box on phase two, and some festoon lights on phase three. Repeat for 10 consumers and you have one glowing and two idling phases. This had me swapping the phase one 150A fuse in a outside distro cabinet in a forest, in the middle of the night, in pitch black darkness. Except for the photons from one small Maglite.
