? For every complex (electric and other) system has regulations how it is built, how it is operated and such. That's what makes 'safety' more than just a word. If there were outages on that ship then somewhere, something was not up to code. Restore power is just one thing. Finding the root of...

By 'fixing a power failure' you mean getting the power back or ensuring that everything is really up to code?

Well, variations of the old classics are always new o0)

Likely some soldering (or other kind of contact-) error.

Company stuff. The SW dev guys at the other desk had a though fight even just to have some Linux running, and at the end they were banished to an isolated network with that...

If you do know what you are doing (and has a backup) then it's fine: there are problems when there is no way around it (it's the easy way around many other problems, actually). If you don't, then it's just like Chernobyl.

Wonders of modern(ish) network hardware when paired with modern(ish) security erm... paranoia erm... lameness.

Yep. Me too.

I think it'll be the 'another'. That detector has no selectivity at all, and since it's not anything specially built for the role (shielding, noise control, meticulous care about any possibly unstable materials and isotopes in structural parts, cleaned for external contamination and sealed in a...

I think the point needs to be precisely centered for this role.

Filer/sandpaper and electric drill/screwdriver. Fix your knob into the drill and set it to (very) low speed. Put a nut on the knob first, so you can fix the thread just by removing it. Also, that plastic 'knob' part just makes it convenient to be used by hand, but usually not really helpful...

No general answer. Some techniques are focused on maximal impact damage, others are focused on speed and utilizes the reflected forces to draw back and some are about maximal transferred momentum (to sweep a leg, for example: without breaking your own).

I would not call them that. Just some kind of self-oscillating boost circuit without any regulation or filtering. If you terminate the current on a coil fast enough you can make some really high voltages without any need to have serious HV circuitry. Example. BTW the same black tube-like...

A small USB powerbank, with an adjustable DCDC converter? Even charging it within the device can be solved with some DIY tweaking. I don't know the current draw so 5V 1A might not be enough, but I would try to avoid messing with batteries if possible. If it's batteries then I would try to...

You can keep a phone watching (with a motion detector running) to have a proof, but disbelief should not be a reason for not being cautious.
