hahahaha, you're a good man and I forgot to say thanks for showing us around a TV. I routinely pick up TVs from the throwouts and tear them down for the parts and de-solder a huge quantity of parts from them. The power transistors are good value, high C and high V caps are good value too and there's piles of coils and transformers in them. Got to be careful when removing vacuum. The usual method is to remove the Ultor connection (the EHT connection into the tube and then carefully punch out the center of the connection with a screwdriver point (careful). This allows the vacuum to gradually reduce in the proper manner without much phosphor coming out. Look forward to more vids from you.
Gort Newton i appreciate the nice comment. yeah, i salvaged a lot of important components from tv boards for hv experiments, its fantastic, sad to think soon itll be hard to find this tube tvs
Just gather up as many as you can now. Take the boards and yokes etc. out and store them somewhere dry and you can disassemble when you like. What I found was that it was much more time efficient to remove every component from a board, place them in A4 sized paper storage boxes (you can buy a 'stack' of 5 A4 size drawer units for a few dollars) and then when parts are needed, they are already sorted and easily found in your collection. The other way is to leave the components on the boards and then go hunting across all the boards for that one component (or several) that is needed and that eventually takes up much more time. For many of the larger inductors you need a big soldering iron, about 75W to 100W as there's inserts in the PCB to help carry large currents through the PCB to the other side. I also use a spring with clip on the component side, de-solder the solder side of that component and then when it is ready to come out, the spring pulls the component out (usually). Have fun, keep safe (remember Tesla, keep one hand in pocket or back from job).
That sunction cup rubber is very good if u put it in front of sucker .. cuz during soldering it doesnt get melt at all and u can pickup desolderd residue easily
The TV had been off for a long time. the most important safety aspect is the flyback discharging. the caps on the board can hurt, but don't present a large danger
Video had the information I was looking for. But please use better safety, I noticed that there was a honey ham just sitting on the ground. Even if the garage seems cold enough for food storage, it's best not to take chances and let the ham sit on the floor. Anyways thanks cheers!
haha yes, after messing with high voltage long enough you come to accept the fact you can get killed quite easily in some situations. and accepting that is kinda crazy hahah. but its my passion what can ya do but just do it safety :D
Remove the flyback transformer, buy a 12 volt halogen transformer, wrap the core about 7-9 time with insulated wire, find the high voltage pin and, WALA. You have a high voltage, very low amperage arc that wont kill you and great for making a Jacob's ladder.
Derek H thanks man, I’ve done this same thing except with fluorescent light ballasts and instead of winding a primary I’d use the internal ones. I’ll have to try it will a halogen ballast
Good vid with some useful information. Awesome effort at age 13 ! I skipped through some of it trying to find info on magnets. Any magnets of substantial size, or even small in old TV sets?
Thank you! Not from my experience unfortunately. Microwaves however have some monster magnets in them. I've gathered about 5 overs the years and they come in handy.
Mvm Cali I’m not sure, but if it isn’t resettable then you could still desolder the flyback transformer and wire it to a custom flyback driver instead.
the best thing to do with those old crt screens would be taking it to a local recycling plant so they can be disposed of properly, since each crt without the implosion band has about 7 tons of pressure, which makes it pretty much a bomb of glass and shrapnel, well, actually about 7 tons or more pressure in its vacuum
how I know is because I have taken apart about 7 older televisions, not old enough to be all tubes but old enough that the tv housings were wooden, probably only one tv if I am not mistaken that I dismantled with a neighbor was actually pretty close to being a tube set, by what I can remember, and another set a little newer, but the 2 electrolytic capacitors for the crt were huge, and they were also mounted to the inner walls or ceiling inside said wooden housing.
+Sonic “Ghost” Dash that's awesome!! wow, ive never managed to find one that old, havent even managed to find one with the older styled horizontal flybacks
@@corbonzo1 I hate when you nerds talk expertise in electronics just to torture us football playing pot smokers. "Duh, uh, yeah, Julia is lead cheerleader, but she got a C in math so I don't think she'll dig me no mo'"
what can practically be turned into money form these T.Vs? Other than copper? Like I understand it seems like a good Idea to keep large resistors etc. But can you actually sell them easily enough?
Do not worry when the financial system failes and the SHTF all these old electronics components will be like gold dust to an electronic engineer like the "transistors,resisters, capacitors diodes, Intergrated Circuits, and much more..."
you bothered to cut the plastic adjusters, then, next step was to remove the clamp holding them in place. Just release the clamp and lift them off, much easier.
Im relativly new to messing about with electronics and stuff - can someone tell me how you can use the flyback transformer and what you can use it for?
Solder the two biggest wires, usually red, white, black or some other color then drive out to the river at night with your girl, turn the car out, thengrab he FBXer and hurl it as hard as you can toward the river, if your lucky, you might hear a splash.
lol I went around on town garbage days and collected them 😂 my mom sure appreciated that lmao. might as well have fun with them and then throw them away XD
Talking about something that could implode on it self and your here man handling the shit out of it and cutting at it i used to pick the tv up and put infront of someone else's house back then
why doesn't any one question, who at which point do u sit there and come up with slapping a mysterious tube into a screen to make picture and sound, still getting my mind wrapped around that
magnets not so much, some tv degaussing cables are copper, dont think there is any gold contacts or plating. there not much worth for money scrapping, just good for components
There are loads of things I can do with 'old' TVs, this isn't one of them! Even a vertical coil oscilloscope hack is better than just taking it to peaces. And did he discharge the tube? Did I miss that?
i showed exactly how to discharge the tube.... you did miss it. Salvaging tv's for flybacks and HV poly caps is a great use. why do you have such an issue with what I recycle?
I do apologise, you did indeed discharge the tube. That post was meant to be more tongue-in-cheek that it may have sounded. Personally I'm just a fan of recycling/fixing old CRT TVs rather than breaking them down and stripping parts.
+HungarianCircuitMaker the flyback driver in there is SHIT!!!! Using a similar sized flyback and a 555timer driver, I was able to get 5cm arcs from 12 volts.
+ivan R nice! i have yet to try a 555 timer setup. and youre totally right about them being shit. the inboard drivers die in about 30 seconds of arcing use. just not meant for it
Corbonzo FINALLY!!! AN INTELLIGENT PERSON!!!!! Im actually surprised yours lasted for thirty seconds! The TV driver I tested died after 30 seconds, and when I tried ramping up the voltage to 8 volts, it simply shut it's self off, and at 12 volts smoke came out. BTW, what transistor were you using for your 555 timer flyback driver? I used a BUZ11 Mosfet, it works surprisingly well. P.S. im working on a royer flyback driver right now :D
ivan R i haven't actually made a 555 yet, only a small ZVS, and another really awesome way of driving them using a florescent light ballast, i have a video on my channel and a instructables if you're interested. great output and itll run forever
Corbonzo I have heard about the flourecent electronic ballast flyback driver, and I tried it out with a 20 watt ballast, however, I was able to only achieve puny one to two centimeter arcs. Although I have not yet tried making a ZVS driver, I am in the middle of making a royer oscillator flyback driver. It should give me 90+KV from 40 volts.
Ok.all good stuff. But the sound quality is NOT that good. Sorry man. You are working just one hand-id so I understand. But the other hand. 😎 your videos are good the training IS 👍👊👍of good stuff 🤟
Color CRTs tubes have Mercury in them. Not smart to be breaking the vacuum seal as the risk for implosion is gone if you break the seal...but it is dangerous for color CRTs for more than just the mercury. Mercury poisoning is not something to play with...and risk.
idk wtf your talking about. I can loose 57 pounds on a Mercury & Lead Diet. I drank 3.25 L of Mercury A Few Hours ago (The organic kind). I hope it works thou because I saw it on some very reliable & scholarly source (I think 4chan or something). Anyway, I'll post back and prove that it is indeed the best nutrient that everyone should have.
***** and that makes me dumb how? i knew exactly what i was and am doing with HV, if you actually watched the video you clearly see the step about discharging the flyback. so there wasnt any danger in it, i play with tesla coils that have more voltage then that. plz.
***** *facepalm* the Flyback and CRT are connected, and it was discharged together. sticking the screwdriver head under the cap discharges both. Go make your own video before telling me im doing things wrong. and learn how to type without caps.
what a pointlessly rude comment. The video is 7 years old taken on an ipod when I was 13, in my garage next to a ham, do you really expect better production quality?
