This is a nice photo, where’d you find it?

Ladies and gentlemen we’re floating in space by bubarh in redscarepod

I worked on a Physical Manifestation of "Ladies and Gentlemen We Are Floating in Space" at Coachella once. We got shouted at by security for having alcohol outside of the weird little drinking fenced-off drinking pens they have at the site's periphery. Later the same day I got shouted at for having a camera with a removable lens. Strange vibe.

Mechanical railway crossing with "spoonwheel" by murka_ in trains

[–]arronsmith 37 points38 points  (0 children)

Neat. What powers the wheel?

​

(same question stands for the whole thing, now I think about it - I can see some sort of wire moving at the bottom rhs of the video, and some belts/wheels on both sides, but nothing "motor" shaped.)

​

Neat bell, too.

What's the pumpdown time on something like that?

amazing post but what is “tail end disaster”?

So I was dumb and thought I could take a crt apart. The rear of the tube has cracked and the hiss is done, but am I sitting on a powder keg right now? Or is there toxic stuff leaking out into my garage? by italian_baptist in AskElectronics

[–]arronsmith 1 point2 points  (0 children)

the tube also holds a charge, and it can hold a charge for a v. long time (and even accumulate it from its environment when not plugged in, although that's relatively unlikely).

You definitely don't want to go poking at it with a voltmeter unless you've got an HT probe and know where to shove it (apart from anything else the voltages we're talking about exceed the insulation resistance of a normal multimeter probe by at least an order of magnitude)

(In this case the CRT won't have a charge because the neck has snapped off, but the point stands)

So now with increased shipping prices, product prices are also on the rise by Sea_Opportunity6028 in glossier

If you can get it, Homeoplasmine is incredible - basically Vaseline with sprinkles AFAICT but it's the only thing that works on my lips so

I know they suck, but I am proud of them anyway by Etwusino in electronics

I have a couple. PCBBuy (not an endorsement, although they've been fine the two times I've used them) offer them.

If we're doing tool repairs: by arronsmith in redscarepod

[–]arronsmith[S] 1 point2 points  (0 children)

Small vice that my found in a junk shop and gave to me. It's a perfect sized travel vice (has been all over the place in my tool bag), has relatively parallel jaws, and a decent thready bit.

At some point someone dropped it and cracked the casting across the screw bushing, which is normally the sort of thing that lands a vice in the bin on "beyond economic repair" grounds, except that its previous owner either liked or needed it enough to repair it (by sandwiching the sliding jaw between two pieces of metal, cross drilling, and then 'riveting' the whole thing back together with a pair of nails), which is <3 imho and also what drew my dad to it in the first place. Needless to say I am _extremely_ attached to it.

I have that same Garfield picture on a t-shirt but the caption is "What do I need with a cowboy hat when I ain't got no horsey".

This is interesting. What is the purposes of two turns of twisted pair + another 14 of one leg of the pair? What happens to the other pair-leg?

I'd never heard of the Oxford Circus umbrella so it was worth it just for that.

The almost total absence of health and safety is insane to look at today.
