Percussive maintenance is a real thing!

I was just about to say that

I worked on something that literally said "to test this thing, hit it here with a screwdriver" because it was known to be a point where a soldered joint would fail

I used to bash the shit out of some stuff with a hammer to prove my diagnoses. It wasn't working anyway, so I couldn't break it more, and I was usually proved correct when I was able to replicate the failure

The whole "well, it's already broken: what's the worst I can do?" is such a liberating position to be in.

I have learnt how to fix a whole lot of things after realising that

Or, I learnt other things that can go wrong, without consequences

However, there's: "it's not working right" and there's "it's not working"... It's usually important to recognise that difference

Was doing this with my car fob for a while before I finally broke down and re-soldered the battery contact terminal to the board yesterday.

Also doing it to my cars blower fan for the AC. I have the replacement fan motor, but it hasn't been annoying enough yet to mess with replacing.

And now interplanetary percussive maintenance is a thing too.

Next step: roll this out over the internet.

Actually, scratch that, that would make some teenage-run Discord servers become online Fight Clubs.

Roll it out with sabers instead far more civilized, we aren't trench fighters. Alternatively if you want a more lethal option rig it up with a 32. Caliber revolver like that batshit insane mouse trap.

U gotta account for the different air density and effects on sound due to that
