Also, pneumatic tubes are currently used in test and research nuclear reactors to move small experimental samples in and out of the reactor's core quickly.

I Appreciate You posted:Also, pneumatic tubes are currently used in test and research nuclear reactors to move small experimental samples in and out of the reactor's core quickly. I GET IT. THEY ARE NOT OBSOLETE.   One thing I haven't seen in a long time are automatic doors triggered by rubber entry pads on the ground. Everything seems to be on a motion sensor now. Those pads seemed pretty cool when I was a kid.

It was a Grand Union, when they went under, it was bought by Shaw's, and they did a little renovation on the inside, but the last time I was there it still had the pressure mats...but that was probably two years ago, at least.

Also reminds me of "electric eyes" which I don't see anymore. I'm sure true optical electric eyes are still in use but when I was a kid they were the most common sensor you'd see for things like door and alarm systems.

Does anyone remember the talking soda machines from the early/mid 80s? https://www.youtube.com/watch?v=IRa4ofB6GV8 https://www.youtube.com/watch?v=p7fQx6E1DH8 I had forgotten about them, and for some reason this thread reminded me!

I once saw an old-fashioned and weirdly shaped hand dryer in a public bathroom, with a label on it explaining how to use the "electric eye dryer", and was kind of  about it until I realized what was actually going on.

AlternateAccount posted:As an owner of these, they are not at all bright. Pretty much can't even see the glow in anything less than near-total darkness. Also I think they emit alpha particles as most of their decay? I can't remember. Tritium vials are used on pistol sights too, and those are definitely a lot brighter than what you describe. There's a noticeable glow even in light. In complete darkness, I'd say that they are about 1/2 as bright as a typical HDD activity light. Given that they are being sold with the expectation of the buyer putting them on something that they keep stuck in their pants for hours every day, I doubt that they'd get away with selling them if they emitted even a tiny amount of harmful radiation.

Killer robot posted:That was Radithor, one of the radium water products of the 1920s. It's not really related to the many things that endanger workers far more than consumers though, like radium watches or careless X-ray use or various powdered chemicals. They even added a "dislike" button! This isn't outdated. It's some sort of retro chic future technology.

Parallel Paraplegic posted:
Even if you did that, nothing. The beta from tritium decay's only 6 KeV, it can't even get through your skin, even if it could escape from the capsule it's in, which it can't. There's nothing else in the decay chain to worry about since it decays right to stable helium. And what's in the capsule is either tritium gas in a tube lined with a phosphor or tritiated water, so if the capsule leaks either the water drains away or the gas poofs off into the air. If you broke one open and ingested it you'd get the equivalent of a couple of years of background radiation, but short of that it's no exposure at all. So while tritium's several thousands of times more radioactive than radium, it's nowhere near as big a deal.

blugu64 posted:You can still get them brand new! I think I am going to ask MY WIFE for one of those beautiful Unicomps for christmas. I had no idea what I wanted until you just reminded me they exist, so thanks! Also, some of the keyboards on the clickykeyboards site are so nice looking. Maybe it's just fondness for what I grew up on, but they just have such a nice, professional, clean aesthetic appeal. Way better than the cheapo mass produced Dell pack-in media keyboard I'm typing on now. I can't wait to get a proper mechanical keyboard. I have long threatened my developers that I'd get one and drive them all nuts [I type fast and I type a lot].  e. I love the gently caress out of the fact that I can order a Unicomp without Windows keys. I hate Windows keys. I am that guy.

This is true! Huh, I kind of like that, pretending my keyboard is set up that way. More ergonomic for, like you said, a key that gets used a lot more than caps lock does.

I remember hating the windows key as a kid, it was where control or alt usually was. Pressing it in DOOM,expecting to fire, then having windows dump you to the desktop with the chance of crashing the game wasn't fun.

Windows Key is awesome, and anyone that doesn't use it is missing out. I use all of these every day: Win = Start Menu Win+D = Desktop Win+R = Run Win+E = Explorer Win+F = Finder Win+L = Lock Desktop Win+M = Minimize Win+Shift+M = Un-minimize Win+Arrow Keys = Do some stuff to your current browser window

I agree with having the Ctrl key in the corner, if I press it with my pinky, X, C, V, S, D, A, W are all easily accessible with one fingertip, where if I hold Caps Lock, I'd have to bend my finger a whole bunch to use half of those. I just remapped my Caps Lock to keyboard layout selection. Much more useful.
