Hey everyone! Thanks for watching and all the comments. I wanted to make a post in regards to some of the common questions, and give a teaser for the follow up. I have put the original transformer back and and even applied 220V, no change. I used DC, no change. I replaced some components....change. I have a second unit now I am building with better components...stay tuned to see how that works!
ОтветитьI hope new CRTs can be made somehow! What you’ve done and what you’ve been able to source are a good start, but I hope we one day see a future where we are all guaranteed to be able to play games like Duck Hunt, Dr. Mario etc the way they’re meant to be played!
Someone on Facebook just told me “new CRTs are impossible to make, making the leaded glass required would break environmental laws worldwide”, surely CRT glass doesn’t need lead? Surely there’s another way?
I agree we need to reduce our carbon footprint, especially in light of how hot the last 2 summers were (which were the last 2 winters in the southern hemisphere) but I still think there should be ways we can still enjoy doing what we do, while still not harming the environment! I’m sure people once said there’d “never” be an animal-safe substitute for ivory, but many have been found over the years since!
Suggestions: 1. Increase the voltage and ampere of power supply, you can use a variable voltage lab power supply but be careful as over voltage will surely fry the unit. 2. Please check if Horizontal and Vertical connection of yoke coil are not interchanged. Please do let me know the result. I am excited.
ОтветитьGood Job, I'm delighted to watch that. Keep it up. God Bless You.
Ответитьgracias!!! por el diagrama!!!, saludos
ОтветитьHey, you never posted an update to this project. I'd like to see this running right.
ОтветитьSir in my portable 12v bw tv a vertical line appeared in the centre of screen what happened to my tv 0please help me
ОтветитьWe shouldn't have to make our own. They won't give us what we want.
ОтветитьUse( transistor 8550) on vertical section picture will get bigger
ОтветитьU.K. has been doing this for years.
ОтветитьCan you make a video of this when it is playing music (To show screen jumping)?
ОтветитьGood luck got love you 😍
ОтветитьIs it supposed to be monochrome, or is it a PAL/SECAM TV receiving NTSC signals?
ОтветитьHi! Brilliant! What is the code or characteristics of the transistor that you show almost at the end of the assembly and is placed on the heat dissipating aluminum plate? Thank you.
ОтветитьWhere’s the link I can’t find one
ОтветитьCool bro! Please can you tell me: it's black and white, right? Any possibilities to have colors?
ОтветитьYou build a chassis, not a CRT.
ОтветитьDid you recap it?
Ответить2022 model crt?
ОтветитьI hate CRT displays (I have very little tolerance for flicker), but I still ended up watching this.
I wonder: could this be a basis for a DIY monitor for use with an MDA/Hercules video card?
I build tube amps from China but I don't use their components but source all resistors and caps locally just to play it safe.
Ответитьbut very expensive. rather just buy from offline parts market.
ОтветитьCan you do another video of this with better material starting from scratch. I would like a color tv demonstration if you can.
ОтветитьAlso I don't recommend leaving that CRT on for so long in the case of not enough width and height because it's concentrating all the light on a small area which can cause burn-in.
ОтветитьGlad I got a few CRTs when they were being tossed out. I sat some VCR combo on the curb and it was gone in an hour. I believe the buttons were shorting as it would wake up and do strange things in the middle of the night.
ОтветитьWho built that circuit board to be able to program the tv to work? If they suck at it, perhaps we can do better? And who built the cathrode glass tube? Is all this from China?
Ответитьalibaba sells crt tvs as a whole
ОтветитьFunny Man
ОтветитьI wish it was color! I need something for my WS4000 emulator.
ОтветитьIt´s really good for training. Finally you have really your own and absolutely original TV. :-)))
ОтветитьYou're a legend and you've gained yourself a new subscriber! I wish one day when I grow up to build a CRT TV for my own future house!
ОтветитьHello;;your problem with small picture,push the yoke all the way forward until stops,this will solve the problem
ОтветитьHello;
Where can I buy the same electronic tools you are using,in your video,thanks................
Hello; you still have the same problem,small screen,does not fill up.....
ОтветитьSmash melee fans can definitely want to find this
ОтветитьI wanna see what we could do with crt technology today cause processing power is so cheap nowadays, we could prob have like 8K 200hz+ crt displays
ОтветитьReplacing parts with better substitutions is not building a kit from Ali express.
ОтветитьThanks to share your find and skills! Please you think it's possible to "connect" a Raspberry (or other similar) on it?
ОтветитьWell, I'm looking forward to see the update. Hopefully you can have some better geometry and no audio/video interference issues. Good luck!
ОтветитьYou definitely have a power supply regulation problem, plus there's a hum bar going through the screen....if you had a good schematic with proper voltages it would be easy to find where the trouble is.
It's a cute little TV.... definitely check the regulation of both low and high voltage supplies.
The audio should never pull the crt pix down.
Check it out.... you may have bad electrolytics as you said.
Esr meter would check if they were good.
Best wishes.
Was this an educational kit, or a discontinued product rebranded as an educational kit?
Ответитьwish their was a color one some day i hope thay will brang color crts back
ОтветитьI built one, the problem I have is that my image is very dull, I suspect that the HV is too low, but the raster fills the whole screen. Once I get mine going properly, I will post videos too.
Ответить"Thankfully it didn't blow up" lmao, can't wait for the follow up!
ОтветитьSituation of image size and sound behaviour seems to be lack of voltage issue. Feel free to contact for debuging)
ОтветитьI agree with others, the power supply appears weak..
ОтветитьI built this tv last week, and get full size image. I think your AV source is NTSC, this unit is PAL D/K, so you got a “shorter” image.
ОтветитьI bought one of these. Arrived with the back of the CRT smashed off thanks to bad packaging. Now I have to find a replacement CRT as I still want to build this.
ОтветитьAssumptions it's trash kit
