Now I know why the old crt tv sets are featured in a lot of horror movies. There's always something scary about these tv sets. People wouldn't get the same scare factor from seeing a zombie coming out of an LED tv.
I used to work as a test engineer in a CRT factory and murdered thousands in the name of quality and I thought the way that neck quietly and deliberately cracked between 3.30 and 4.00 almost brought a tear to my eye. In real world, the neck has been designed to break off during implosion such as hammer or projectile hitting screen throwing the kinetic energy safely out the back (rather than throwing half kilo chunks of glass at the viewer). Poor little tube tortured to death for our fun and scorn. You should remove the main band with a hacksaw and do this again, you get more glass :)
@@johneygd I guess the picture would reduce in height to keep the combination of vfreq and hfreq within parameters? Which is the khz rating. 240p x 60hz = ~15khz. Each set will support a "range" of khz values and that's how you work them out. CRTs are versatile creatures. Increase one metric and quite likely yes another metric will simply reduce itself accordingly to keep khz in range, the beauty of analogue signals. A black /scrambled screen, or only displaying every third field (frame as you might know it but its not a frame it's a field refresh) - these are both less likely to happen. So I reckon your tv would be just as happy running 240p@60hz as it would be running 80p@180hz. There's a limit for everything I guess. And whether it displays the extreme examples fully accurately or not is debatable and mileage may vary. So a signal of say 8p@1800hz is not going to do much for you visually I imagine. But really that would be just as acceptable for the tv as the generic 240p60 standard. And if you went 1800p@8hz, yeah the TV may not necessarily fall over and die because of it. But, the actual holes in the shadow mask or aperture grille on the set ain't going to be anywhere near small enough for the 1800 lines of image to be discernable. And, the headache it gave a human would most likely be not too pleasant. Hope it helps. Bet you're glad you asked 😂 (probably not)
sorry to be off topic but does any of you know of a trick to log back into an instagram account?? I was dumb forgot my password. I would love any tips you can give me!
Older CRT televisions were a great source for vacuum tubes, stick diodes, large capacitors, a large transformer, potentiometers, large transistors and large resistors. Then that all went away in the 1990s. A lot of the individual components were replaced with integrated circuit chips and solid state components. Only the actual tube and a few surrounding components were still individual. There were some nicd 7400 logic gates and a few standard IC circuits. But for the most part most of the integrated circuit chips were propriety. I could not salvage a lot of components in the 1990s. Now the vastly superior OLED televisions are out and almost nothing can be salvaged. Ironically, now that little can be salvaged from a lot of electronics, RadioShack has ceased to exist. Thus, we have less components we can get from salvage and not many electronic component stores. Hobbiests are definitely the loser of the current trend.
Whether they're "vastly superior" depends on what you're looking for. People who play old video games (like Super Smash Bros Melee) prefer CRTs over OLED monitors for the lack of input delay. Also, it's been shown that older games look better on CRTs (you can easily google CRT sprite comparisons for reference, for example).
+Lord Smuggington OMG, The Topgear crew makes a new Series and he is offline for months now...hmm stuntdouble? Or ACTUAL Tesla Car? Oh boy, wouldnt it be great
As a child, I visited my father at work where he was operating a small reach lift to get merchandise from high areas. My father was getting a combination television/phonograph /8-track player/ AM FM Stereo/ shortwave tuner system. One of the forks on the reach lift sagged and leaked an oil and the combination entertainment set fell from full hight and exploded when it hit the floor. It sounded like a bomb when it hit and made sparks when it hit, even though it was not plugged up. It was not my father's fault so nothing happened to him. I was only about eight years of age. But remember sitting in the break area watching it unfold in front of me.
Watching that made the hairs on my arms stand up . Love the evidence on your flooring of previous experiments . Love the no bullshit video . Thanks . You have another subscriber.
True 3 D TV. Love the end when you are behind the empty TV case. Great video, lots of ozone. Somehow TV's have a magic attraction for electrical experiments.
im scared of crt tvs and electricity. I love crt tvs and have many, but as soon as they make weird noises i unplug them. One time i got insulated gloves, crocs (so the rubber will prevent the electricity from flowing through me to the ground) and a crutch to press the on button to see if my crt tv worked, it made weird noises so i unplugged it, never to be used again. You guys are brave for even opening a crt. i could never do that. awesome video. earned a sub and a like! :3
DelilahThePig - We have Millennials in their 30's. I am one of them. Our generation was born between the years of 1982-2002. So yes, we know what a "regular TV" is. And we still had CRT's in the market until the early 2010's though they were uncommon at the time. I have a used Sansui manufactured in 2009 with a few SD consoles hooked up to it in a spare room.
why not make a diy xray? fuck, think about it, a black plastic covering the screen, a little overdrived crt, and in the other side you put the person and the capturing phosphor screen with a high exposure camera attached to take a picture, you might project a white screen, either electronically or by other means, probably detaching some synchonization circuit can do the trick.
They will if their overcharged. Servicing them is like disarming a bomb - their capacitors are enormous and are usually charged to hundreds or thousands of volts, and most of them have no bleed system that drains that charge, meaning that they can still be dangerous months or years after the last time they were powered up. A discharge can not only electrocute you, it can cause tools to melt or explode.
i really have one question... how much are your electricity bills in the month? :D don't understand me wrong, im just asking because your'e dealing with so extremely high voltages!
realgroovy24 tech still the more amps you're pulling the more wattage you are using this is why he makes most of his videos at night because in the UK electricity is cheaper a night
D4Tw33K4ZZ The equation is watts=volts*amps, so you can have the same number of watts even if you pump up the voltage. The amps will decrease. Same applies if you want more amps - your voltage decreases. For example overhead power lines are high voltage but low amps - that's how power is transferred over long distances without much loss. When they get to your home they go through a transformer so you get "only" 120v (or 240 or whatever it is overseas) but a lot more amps so your hairdryer and refrigerator and other appliances work. Except Photon puts all this back through another transformer to get the high voltages like before.
the creepy part is I have that exact tv and it hasn’t been on in like 30 years. I was building courage to plug it in, but all was lost after seeing this video.
When you have a vacuum and there's nothing to slow the electrons down, the difference in potential of the high voltage causes those electrons to jump the gap with a lot of energy - more and more as the voltage goes up. When those very energetic electrons then hit a sudden stop at the cathode or screen, they release all that energy at once as a single photon. The energies are high enough to send the resulting photons into KeV energies, which are ionizing.
Saw another guy set up a geiger counter facing a CRT.. he turned the voltage up nowhere even freakin close to this high and got a massive burst of xrays out of it before he turned it off... Our mate photonic here got a pretty big dose of xray radiation here. Eh, he'll prob be fine, but still not something I'd wanna be playing around with. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-UbfSpiatxFo.html
@@joemarz2264 oh you mean the flyback? the cable on that usually shouldn't shock you, but yeah that and the anode cap are where basically all the electricity is at, glad to see you're okay, though!
Photon burned galvanized tools in that room too. His newest videos he is talking about free energy and shit (straight quackery), I wouldn't be surprised if he doesn't have neurological damage from heavy metal exposure. Dude is going the way of Tesla claiming he can use 5lb of air pressure to knock down the empire state building, but of course nothing is finalized and he can't show you for fear you might steal it!
Yes he is aware that it is but he does shit like this all the time because it’s his job, hints why he always puts on his videos “Don’t try this at home!” CR TV’s will admit gamma radiation if it’s overcharged. Servicing them is like disarming a bomb - their capacitors are enormous and are usually charged to hundreds or thousands of volts, and most of them have no bleed system that drains that charge, meaning that they can still be dangerous months or years after the last time they were powered up. A discharge can not only electrocute you, it can cause tools to melt or explode.
