Jonny 290 posted:Nice. I remember a dark age in broadband where ISPs figured out they could sniff packet TTL coming out of your connection, if it was 63 you were using their (obviously lovely) router, if it was 62 you were using it as a bridge and using your own router which they got real mad at. Solution was to pop some iptables rules into your router to +1 the TTL this still works if your mobile provider meters or restricts tethering

crts are weird in the realm of vintage tech. I work in e-recycling and crts are one of the only vintage technologies that have not only depreciated drastically, but gotten more costly to deal with. yeah nobody wants that old VCR deck, but as a recycler I can at least get something out of it. the only way I can do that with CRT’s is to mark up my costs on them CRT’s are just a chain of ever increasing markups. there are literally executives at the top of major recyclers going to prison for mishandling CRT recycling. it’s insane how expensive and problematic they’ve become from an ewaste standpoint, so yeah, people should just be giving them away if possible.

and they're some of the hardest things to repair too. a VCR or cassette deck may need a belt kit. stereo might need an electrolytic cap job. CRT? enjoy seeing your life flash before your eyes as you do a high voltage filter cap replacement and attempt to replace a whining flyback transformer. I will gently caress with a battery bank that can burst discharge 1,000 amps at 12v, i'll run coax cables with hundreds of watts of RF across a bench next to a cup of coffee, but I will never open a CRT that has been powered on in the past year.

They seem to be getting a bit of love in the retro gaming scene, but I think those people are very particular about which models they'll use. Legit though a friend of mine was asking about whether it's a good idea to just walk off with one from the e-waste site in his town. (Sounds like probably yes!)

A lot of ewaste places will give away CRT's. Someone already paid them to take it, and if you take it for free it means they can pocket that money and not pay it to the next step in the chain of recyclers.

I watch a lot of antique/vintage electronics channels on Youtube that restore CRT TVs (mostly 50s-70s sets because those tend to use mostly general-purpose components and not the unobtanium proprietary parts that 80s and later sets tend to use) and it's doable, but definitely on the harder side for hobbyist electronics. Part of the difficulty is that you definitely need to have the right tools to do it, and many of those tools (especially a high-voltage probe (which also lets you safely discharge the CRT), a CRT tester so you know if the tube is any good in the first place, and a professional signal generator to generate all the test signals you need to verify and align each portion of the set) haven't been made since the 90s since that's when TVs transitioned from being expensive items that were worth it to fix to being disposable items you just replaced when they broke.

repair industries have changed wildly over the past few decades. There are so many fewer points of failure - you'll almost never see things like a blown power transistor or whatever any more - but filter caps are always rotting, and will eventually always need to be replaced. It's why i completely ignore the "NIB vintage 80's ham radio" listings for high prices on ebay. I don't care if it's still wrapped in the original plastic, it needs a cap job.

How are computer recycling companies not getting away with doing the traditional "recycling" solution of "selling" the CRTs to a company in another country who just "accidentally" drops them out of the boat after pickup?

I once accidentally CRT TV set and all the televisions hissed out the back. I don't know why I tugged at the "plug" but I didn't think it would just come off dead easy and let all the uhh gas out? Air in? IDK. Also, why the gently caress was it exposed without dismantling anything? And why was the back shell of the TV cardboard? The wonders of European 1970s televisionity.

That by itself shouldn't have broken the vacuum, though the "neck" of the CRT (as that part is called) is usually the most fragile part of it so it's definitely possible if you used more than a gentle amount of force. If the neck was just exposed out of the back of the set then the set was probably missing the part of the back cover that was supposed to cover the neck (which usually was the part of the set that determined how "deep" the cabinet needed to be, so sometimes a bump-out extension on the back cover was used to make the rest of the cabinet thinner).

CRT? enjoy seeing your life flash before your eyes as you do a high voltage filter cap replacement and attempt to replace a whining flyback transformer. I know a bunch of people who work on CRTs in the retrocomputing scene, they’re not that bad, you just have to know how to discharge them and work with them safety (one hand in your pocket, tools made of insulators, that sort of thing) I’ve even done a tiny bit myself with classic Macs and terminals, nothing beyond just replacing parts but I’m far more worried about necking a tube than I am about high voltage when the CRT isn’t operating much, much more difficult is fixing “CRT cataracts” where the adhesive between the implosion/radiation shield glass and the actual picture tube is breaking down to do that you need to remove the implosion shield via VERY EVEN AND STEADY heating to loosen all the adhesive at once, clean both it and the actual CRT, and then reattach it with a modern adhesive it’s very easy to crack the implosion shield via uneven heating with a heat gun—at that point the CRT is still fine, but good luck finding another glass that fits perfectly if your tube is non standard (like say my friend’s AT&T BLIT terminal, with its portrait orientation) so you’re going to get a nice little dose of X-rays every time you use it I have one “reasonable, standard” tube that needs fixing this way, a DEC VR241 monitor that’s part of a VT240 color terminal, and an oddball custom tube that needs fixing in the form of an HP 2647A widescreen graphics Terminal from the late 1970s which I do not look forward to

polyester concept posted:i used this all the time. it just found other mirrors and would do simultaneous downloads of individual chunks and combine them in the end. no idea how it found other mirrors tho I thought about it for a minute and I think I'd do it by sending the URL and a hash of every downloaded file back to a central server. You just collect all the URLs that you've seen linked to that hash and over some period of time boom there's your database. If the file was popular, like a game demo, and you had a big userbase I bet it would happen pretty quickly. Alternately in that era it could have been just a manually updated index that covered the most popular downloads. The internet was a lot smaller back then.

It was just a not special 17" Dell CRT, but a comparable one on ebay sold for $80 + $150 or something. But then when I tested it out the colors were messed up so I decided to scrap that, I didn't really want to deal with shipping it anyway.
