I explain and show off my 1 transistor flyback driver and show some sparks and arks that it can create. I also show how to connect it up to a CRT to project a dot on the screen using the flyback.
You remind me of my son. Good job. Take what everyone complains about into consideration but decide for yourself what to change. Your focus and attention are pretty good for a kid. Good video
I agree. I made an astable 555 driver (that uses the 2n3904 and 2n3906 with a power transistor). I rectified a 24vac 900ma power supply and put it in series with a 6v battery and a 12vdc power supply, while using a 2nd 6v battery to drive the 555. It was a total of 42 volts going to the flyback and I got 75kv out of it and 3 inch sparks. There was very high current and it was enough to burn plastic and melt wires on contact.
CRT's implode when broken. Best to deactive them by breaking the vacuum seal with pliers at the end of the gun assy. There will only be a few seconds of air rushing in. Protect your eyes with safety glasses before doing so.
wow the sound is amazing !
i hate your tripod!very nice video... bad audio!
Rulof sei internazionale ormai eh! xD
WOW! Sounds like the 555 drivers are way ahead of the 2n3055, still you had an amazing setup with 42volts. Did the 42v kill the flyback?
I forget the exact figure but somewhere around one amp + or - about 300mA, so not too much. I think I may have gotten it to 2A once but that may have been with a short thick arc or with a CRT TV.
Try swapping the MJE13009 for a TIP35C and you will get a much better arc. I have tried with several different transistors including both the MJE and TIP. TIP wins hands down. The rest of circuit keep as is. I also tried MJE13009 in parallel also TIP35C and 2N3055 the 2N3055 wins the parallel. I am going to go the voltage way and try mosfets next. Keep experimenting its great fun!
ANY OLD TV ORE MONITOR TR USE

The horizontal output transistor that drives the flyback transformer in most tvs have 160vdc on them. So 160vdc is high speed swimming the flyback.
Cool, I have the same exact flyback, gonna try this tomorrow.
This is quite the case. There is often a great deal of misconception over the current/ voltage issue where folk tend to say that it is the current that kills. EHT is quite capable of killing a person at just a few milliamps.
thanks for the effort. good video. very hard to focus thru the video cause the background noises that the microfone pick up are omnipresent.
HI , I have a question for professionals, (or maybe not).
Energy is transformed right nor created or destroyed, then if the power of a 12v 10A battery is 120 Watts and those 120 watts don't kill you even if you put the battery in your tongue, Why these flybacks are so dangerous? They keep outputing 120 w with a higher voltage but the amperage is inversely proportional so there should be not much current flowing...
This is troubling to say the least.
hey. i wonder how did you know the pin of the model FQM-17B003. i can't find the datasheet for this transformer. plz help me
If I had 3 pins that had continuity with each other, how would which 2 are my primary? Or is all 3 interchangeable?
Maybe for the holidays, but don't get your hopes up. Defiantly by August.
Bro, I really appreciate a very informative video, however , try to position your mic. away from your hands .......because the sound of different tools or materials moving around on your desk was very distracting and even blocked out some of your tutorial.
in order to get bigger sparks,
you simpley need to use a higher voltage on the flyback driver,
like 12 volts, cuz other flybacks that i know of work with 12 volts...
i dont know how i got here or what you're talking about, but it's very interesting
+Duffimus Prime I must have made that same left turn a couple of video back.
@axelasdf Thanks:) My camera has no spot for an external microphone so instead when im editing videos in imovie i take away some of the background noise. As a consequence of less background noise i sound like im on the phone so do you think i should sound more normal with more background noise or on the phone with less background noise.
Def seen that skim before... Loads of times. My buddy drew one up just like it to wire in the carb on his 67 transam.
i have a similar tv it when i turne it on the red light shine and i hear sound but the screen doesn't light
sometimes when i lean the wohle tv to the side, the screen light
so please wt the problem??
Hi, Brad
You'll realize far better results winding your own primary and feedback coils (4 to 5 turn primary and 2 to 3 turn feedback)
Of course you'll need to find a flyback transformer with sufficient core-space to accommodate said windings --- Useful transformers are often present in older TVs and CRT monitors...
Most flyback transformers don't contain windings adaptable to the Royer topology -- Hence the presenter's difficulty locating a suitable transformer...
DUDE ! Leave your figgin Camera ALONE ! And get a seperate lapel microphone .... Still, neat little project ...
for real.. 6:30 and can't take any more of that fing noise
Michael Kaufman.. same here i stopped watching at 6:21 couldn't take no more
Nubie Bob Me too. Let's not forget the noise of the fosussing mechanism.
very educational video and very clearly and coherently presented
you really need a new camera though lol
the zooming and moving sounds are quite annoying
My morbid curiosity forced me to watch more especially considering the comments. At 11.29 my heart was in my mouth, you grabbed the CRT in such a way that was soooo dangerous.... good grief.... if that neck had broken (And they are fragile at this point) with your hand around it, you could have been picking glass out of your hand for weeks.
Dealing with a subject like this that you clearly have little knowledge of is wrong......and dangerous.......
can i know how many turns of primary and secondary winding ? and the mutual inductance ?
also i want to know the value of output voltage ?
i want to use this transformer in full bridge converter so i want to know electrical specification
You should be able to burn and melt thin metal with the kind of voltage flybacks give off.
I get it because I am an Electrical Engineer...and since this was made in 2012...and to day is 2015...but holy crap man...Dude, are you still alive?
Was this particular transformer rendered from a pc monitor?
No, it came from an old CRT TV.
No, it didn't. I am upgrading the transistor to a IRFP250 mosfet (i ordered it and it should come by friday). I can't wait to see what voltage I can get up to.
I do that with my newer videos so let me know if it's any better.
Yep, but you can push it for higher voltage, just don't expect the transformer to survive.
Can you replace a flyback on a 36 inch toshiba tv??
Why do that? Scrap it out for parts and get a new TV
so what sort of amperage is that? could it potentially kill you?
What is the voltage of the TV transformer?
FWIW (RE: your half-Royer schematic) the feedback phasing is drawn incorrectly (to wit, inverted)...
Offered with constructive intent..
Dan
What is all that NOISE! You are ruining this video.
how old is that camera jeez but thanks for the video.
+1 to the above comment. you got really nice videos and quite educating too but with the constant changing volume of the sound it's not as good. as another way to solve it is to record one with external Mic. separately and just to mix the vid+sound, syncing the two
It is hard to watch with all the noise like the others described, do people watch their own videos at least once?
Watt are deadly, amp are dangerous but low risk than watt, volt don't kill you.
be carful when u get a old tv and try to get the flyback driver off i broke the backside and there was allot of presure on the glass part of the screen wich im or explodet on me not sure but it was raining glas particles so cover it whit a old tshirt or somthing and vent ur room good if u try to get it off ^^
Yeah loudest tripod EVER.
Was this filmed on a speed boat? 14:18 :-)
Muy bueno pero que clase de revolú tienes ahí!
interesting but I cannot watch to end!!!! Has to be the noisiest and most annoying video I have seen... and I have seen a lot!
Y'all complain too much. Great vid, very helpful
My guess is that is is in the range of 500uA or 1mA but it could be higher or lower, that is purely based on guessing. I doubt it would kill you, with sparks like mine, but it would burn you, some of the people with huge arcs with zvs or 555 drivers could get enough power to kill you.
The content in these videos is great, BUT YOU NEED TO GET AN EXTERNAL MICROPHONE.
This is a fantastic video!
Ya, it's really cool and a lot of fun.
Flybacks are usually 12 volts.
I mean, if you talk between moves, it is easy to strip in video edition.
Si es un poco desorganizado, no tengo tiempo para limpiar. Tambien todos los personas famosas que hicen desenar electronicos tienen desordinas muy largas. (pardon mi espanol malo, mi ordenador no tiene lengua espanol por su lengua, y tambien yo estudio espanol por menos de cinco anos y no aprendes mucho en las clase de espanol.)
you need to put back the yoke coil that makes the dot big.
That was useful for what I`m about to do and for a younger person you knowing about this older technology is impressive. I might have some questions once I get into a repair project in the future...Also I`m having trouble with making a Flex capacitor for time travel...are you familiar with those also ? LOL
thanks for video.interesting
I totally agree.
11:21 Never hold a CRT tube like this.
Why..?
@@Aceino I think it could break easily imploding violently
if you want to live longer you should ground the side of the flyback thtas connected to your newspaper :)
For ? I don't know
Nice video
Cool???! With THAT sized Spark
+Wade Bishop it is, but in this video it is not running anywhere near full power. I was able to get 5cm arcs out of it., but I used a different circuit.
@quicknuclearscience
When I try to listen (expecially with my headphones) the clattering of the camera bangs in my ears. It makes it hard to enjoy the content. The background noise is a DEFINITE distraction. I would try selective muting and only speaking while the camera isn't being moved.
Your welcome!
I understand. I always got coronas around my arcs.
Amazing drawing skills :-)
You need a new camera with a separate audio processor-It is noisy. Touche...mine is not the greatest either. Great job though.
good presentation thanks a lot
I did not finish watching the video because of the distracting background noise.
More than likely that flyback assembly has a part number printed on it. If you
Google that part number you can find a link to a schematic diagram of the flyback itself or a television containing that flyback. One or the other of these schematics will list pin numbers which will help you identify the corresponding terminal pins on the flyback assembly. I did this for a very similar flyback assembly not too long ago. I don't know where I saved the .pdf file of that schematic or I would give you a link to it. It did not take long to find.
How to make this:
Uhh
Tv open heart surgery

Presentation is not comfortable. there is gap between audio & Video visualization. Screen play is to be improved.
news paper is printed with carbon based ink man i shocked my self once with a news paper switch
Ya, if only...
I think so
The 2n3055 is 3 fricken dollars at radio shack
never mind that, just don't touch the camera. Not for zoom, not for anything. Bring the part in the camera's viewing, not the other way around. Stop trying to zoom in. It wastes time focusing, it makes annoying noises...Audio is decent if you don't fiddle with the camera. Good luck
Wow. I hope you replaced that camera.
What is all the noise, scratching and scraping and banging, damn. I'm sorry but I can't bear it, I would love to watch this but hell man.
blowing up the flyback... I hope he meant transistor because you only risk that at 24v+
I wish I was brave enough to even LOOK at the flyback transformer -_- I'm in the middle of deciding whether or not to trash a mitsubishi rear projector or attempt to fix the high voltage board. (21 error) gosh damn it....
Please check out my 2013 flyback transformer driver
If the sound is hard to listen mute it and turn automatic legends
If the legends doesn't make sense put the sound and back to listen
Much more better doing this
very oor video recording...!!!
🎉
What is this? " Death Wish ONE"
spark! spark! spark! what the hell is that for?
you've got really good information in this video, but with you constantly moving the camera around, I can't really comprehend what you're doing. you don't need to zoom in and pan around to each part individually. try leaving the camera on a tripod for the next video
gooooooooooooood
You don't have a step by step system for teaching so must of your knowledge evaporates into the air, there is no sequence to it neither without forgetting the camera problem and the too fast talking...Which it would be okay it was structured.... We could know a lot but that doesn't mean we can teach unfortunately...I'm still learning, keep trying!!
Bought this one from ebay and it seems identical to the one in his video. There was a diagram for the internal circuitry of the transformer:
i.ebayimg.com/00/s/NjAyWDUzMA==/z/w04AAOxy0bRTAO-4/$_12.JPG
audio was painful goo
d job
also short all the caps BEFORE touching anything i shocked the crap out of my finger because i was thinking it wanst pluged in for 2 to 3 jears caps schould be empty ... i still could hit myself for being so stupid ^^
... and what did we learn from this 'experiment'?
That a very noisy camera!
low voltage
Come on dude, this could have been so good if not for the shitty camera work. Oh well, very facinating anyway!
ese circuito no funciona nada me canse de hacerlo y no funciono nose porque se empeñan en hablar de eso.
