Yeah, for some reason YT recommended this channel and I was overjoyed at the content and really great explanations coupled with true Zombie Apocalypse resourcefulness!
Any time I have heard the prospect come up in forums, people have always been dismissive. Good work! Getting any discernable signal at all with a tube you vacuum-sealed yourself is amazingly talented!
I am seriously impressed with this! I really am. I wonder if its possible to eventually get into rebuilding vintage CRTs again, replacing the cathodes that have been used up on antique TV sets since all the rebuilders are gone now.
Thank you! It is possible. The early television foundation has all the equipment needed to rebuild tubes they just do not have anyone with the experience to operate it. I do not currently have the equipment or skills to rebuild picture tubes unfortunately.
My jaw dropped when I saw the first video in this series where you do all the welding and glass blowing... Seeing the whole process and your detailed explanation is incredibly fascinating!
Seeing the complement from Applied Science, I am nobody, but I am awestruck. Absolutely amazing skills at your hobby. Thank you for sharing, this is very inspiring.
I just discovered your channel and I am very impressed that you dare to build vacuum tubes even with the simplest tools. Your knowledge is on the level of UA-camr Ron Glasslinger who also has a wide range of knowledge from electron tubes to transistors. My knowledge, throughout my professional career, also ranges from electron tubes to complex integrated circuits. Technically, I can understand very well what you are building. I enjoy following you. Electronics has become a very broad field from the first transceivers by Marconi, who did not yet have an electron tube, but did great things with the means of the time. My younger, former colleagues are fit in the development of modern electronics, but cannot understand the function of radio receivers or televisions from the early days and cannot read the circuit diagrams. In a few years this knowledge could be lost. From now on I will follow your channel and look forward to more videos. I wish you a wonderful time. Herbert from Southern Bavaria
I recently learned of the profound historic importance of the CRT and the revolutionary discoveries made from experimenting with it. After reading about it I got on UA-cam to see if I could find a video of a Crooks tube in action and came across you building them. I'm totally amazed! It's electrons and x-rays ahead of just being our picture tube.
Being an absolute novice with basic electronics, I know how much work and effort and passion this was to get working. With one video you have me Subscribed. Most channels cannot do that for me. You inspire me to learn more about electronics. Thank you for sharing your work, so impressive!!
That's absolutely amazing! I've seen a few CRT projects where people were able to display simple waveforms, but never an actual video signal! The most I've managed personally is moving a large spot of light with a magnet :P Keep up the great work! I look forward to seeing what you do next!
This is amazing! The work you are able to accomplish with minimal equipment is nothing short of astounding! I'm definitely going to spread the word about this channel among my various science/engineering friends. You deserve a LOT more subscribers! Fantastic work!
Your use of a Baird NBTV signal is genius. I've been fascinated by televisors since I hit upon the idea of using one as a post-apocalyptic terminal display that would be easy to bootstrap from a late-19th century level of technology. (an incredibly simple design could theoretically be driven by a couple of pins, one bi-directional pin if you really need to.)
I love this. Like mad scientist lab from the 80's. It has a lot of charm. Interesting experiment! I didn't knew that video can have such a low bandwidth!
Very impressive! Are you self taught, or did you receive any formal electronics training? I am most impressed with folks like you who make their own tools. I noticed that you have videos going back to 2010 or so! It is nice to see the progression of your abilities and knowledge. They told us in the '80's when I started electronics that analog would fade and digital would take over. I'm glad that turned out to be false!
What a cute CRT! Brings back memories too, playing with NBTV, hehe 🙂 They made the 913 CRT in the 1930s, which was like the almost smallest CRT ever made. But this is way cuter! Regards, Thomas
Haven't watched the video yet but, I subscribed anyway. Love that technology like this and the process to make it is being kept alive and being documented for us all.
Naturally... in colour, a look inside a color picture tube factory. (found it on youtube), now it looks little bit clear than before... you did great job!
That's absolutely nice electronic practices, knowing the basic of electronics is very important. Till today I also do electronic practices just to prove that what I have in mind is right or wrong.
This is excellent... I've been playing around with feeding signals into a TV that it doesn't really expect to be fed into it. Your circuit explanation is giving me a much better view of what it is that I'm playing around with. :)
How impressive !!!you are wonderful !!! Being able to demonstrate and explain the the process of delivering a picture on a home made CRT is amazing......My best efforts was with a radar VCR97, in geen, and some EF50's etc. Pictures from the BBC transmitter Holm Moss from Winter Hill Bolton were magical. Thanks Please keep the info coming
dude, your skills are amazing bro. Ive been doing hobby electronics since I was like 5. and watching someone like you build tubes from nothing is amazing I do have a question for you, if this comment doesn't get lost Why? why do you do this. Do you like old tech and want to relearn the old ways, have skills encase we get emp and you get the grid back up. I hope this is not a condescending question, but what drives someone like you to learn out dated skills? I'm just curious what is your specific reasoning for finding meaning in this amazing skill you possess. ITs funny, because I wrote on my do do list about a month ago. "learn glass blowing and then make nixie tubes" and then you popped up. I also didn't say this out loud, wrote it on paper. so thanks google for yet again reading my mind.
Good job with the uniformity of the coating! I'd love to try this some day. I noticed they have some phosphor coatings available in (expensive) aerosol spray cans. Also, this analog circuitry stuff is black magic voodoo to me.. id sooner try a find a way to use microcontrollers driving DACs, etc. Being honest with myself though, I'd probably get stuck at the glasswork.
Thank you! The coating is definitely the hardest part it usually takes a few tries to get something acceptable. I never could make myself like digital! I have done work in the past with embedded microcontrollers and I can't keep everything in my head at once how all the different pieces interact across different blocks of code. If it has ten or less parts with a couple transistors I have at least a chance of wrapping my mind around it.
Glad to see the CRT in good use, it's still an impressive sight to behold even though it's a bit blurred. Have you tried the focusing coil yet? Might take a quite a bit of power to force all the electrons closer together, but it should as you most definitely know improve the image at least a bit.
I am building one right now, I think it is going to take an awful lot of wire. I am first going to try it with 39 gauge since I have a lot of it and I can get a lot more turns in a small space. It probably will end up needing a few hundred volts in the end.
@@jdflyback JD, in DC driven coils, voltage is meaningless. It is all about the current. Unless you have a truly hard vacuum in the envelope of your tube, it will probably never focus. I keep having a flashback, "gas focused tube". I think that may have been in the days of the Braun tubes which operated at 100,000 volts minimum. They used a tungsten spike cathode, not heated, and need tons of voltage to emit electrons from their tip. (And X-rays from the anode) Those electron guns only lasted less than a day. It is a safe bet that focusing the beam was also equally primitive at the time. If you run any vacuum tube at less than 16KV, there is no danger from X-rays. Even above that voltage, the X-rays created are of the soft variety and are blocked by the lead glass of the tube. (referring to 14 inch and larger monochrome TV CRTs.)
@@videolabguy Thanks for the tip. The coil I made used 39 gauge wire with about 5000 turns (as many as I could fit on the form). It ended up being 3700 ohms. Because of the high resistance I was using high voltage to get a high current. and have as many amp turns as possible. Even with around 20 watts going into the focus coil I did not see any sharpening. The tube probably has some resisdual gas in it. The supply I have can go to 30kV and the tube makes a lot of soft x-rays when operated that high (pegs my geiger counter). The geiger counter lets me know when I have gone too far. The only solution I see right now is to keep the anode aperature small at the expense of low efficiency and a dim trace.
Absolutely termedus effort. I did not think anyone under 30 was interested in vacuum tube equipment. And I'm surprised your channel views are small and I even found your channel. What's so cool is the things your making will have a super long life span compared to many modern electronics. Keep going and you will have million of views I'm sure. Can't wait to see the camera build. What eles do you have in the works? Gravity modification? I learned vacuum tubes becuase I wanted the fundamentals of how our world works. A thousands tubes later I still don't know how the ufo works.
im 17 now and ive been making stuff for a while now. I used to be interested in electronics but that died years ago... Until I recently started modding 1960s night vision, and i came across this channel that inspired me to start building my own vacuum tubes. The goal is to build a working infrared converter tube
What you are doing is fantastic. Maybe you strive to be authentic, but if not, I can recommend driving the tube with digital function generators. No need for complex circuitry. Just 3 D/A converters for X, Y, and Z and some software. Almost all small embedded chips will include all this for a few $$. From Arduino to Cypress Psoc and many others. I did not make any glass parts, but used an old Tektronix oscilloscope tube to make a monitor for a computer I built.
I have thought about it! Would be quite a challenge. I think I would have to come up with a standard tube first. Every one is pretty much unique right now.
@@jdflyback I managed to simplify an analog video to oscilloscope converter down to just 3 transistors, perhaps a similar thing could be achieved with just a few tubes as well and used to drive that CRT of yours.
@@jdflyback "Every one is pretty much unique right now."🙊😂😂😂 So cool..::: It's really inspiring you've demonstrated the feasibility of diy valve manufacture!!!

Hi, this is amazing!! Congratulations!! I am trying to build a vacuum tube myself but I have problems in finding a way to find if is vacuum sealed, i saw you are using some type of HV transformer, can you tell me more about it, where should I look for more information?
The supply is a classic single transistor flyback driver driving an ac flyback with a tripler. Search "single transistor flyback driver" on UA-cam and there are a bunch of videos. You can test for cracks and pinholes in the glass by pumping the tube down on a vacuum pump and moving a high voltage wire across the tube. Wherever there is a crack the high voltage will jump into it lighting up the tube. I also have a a video showing the constuction of a triode if you are interested and show the testing at 27:44 ua-cam.com/video/vfvfgGj521M/v-deo.html.
Very impressive. That is probably similar to what they got the first time. It looks like the red wires from the box are getting pinched in the hinge. If you squint it makes it much easier to see the contrast, it will remove most colour information I can see the image clearly if I do that that is a trick from life drawing.
Have you considered making a 7JP4 clone? It was common in 1940s TVs because it uses electrostatic deflection and therefore doesn’t require a yoke. It also uses an Einzel aka “monopole” focus.
you could use a camera to take a reasonably long exposure of the CRT screen to display the picture as is seen by eye in the video. also it would be interesting if you tried to put the evacuation tube within the seal for the connections at the base of the CRT. and if you're making another CRT project, you could try using those fluorescent green stickers for the phosphor, I think they're zinc oxide, similar to the P1 phosphor used in monochrome monitors but with longer persistence
Okay, this is super cool. If I work hard enough, maybe I'll be able to make the tube I need for a project, as I've been unable to find one in the dimensions Id like for a project.
Dude I don't know what made me click on your 1950s tv build but man your channel is great and I am very impressed with your work but I must ask how old are you
I'm glad that I found your channel. Really great work!

imagine playing in a crt lightbulb. So epic
Awesome work!!! Very Cool!!
you should try this but with a beaker's base as the screen to make it bigger
hi we need a video about how to make a photocathode and a phosphorus screen , thank you
Have you considered making a 7JP4 clone? It was common in 1940s TVs because it uses electrostatic deflection and therefore doesn’t require a yoke. It also uses an Einzel aka “monopole” focus.
Dang; why did it take so long for me to find this UA-cam channel.
Awesome project! Its really hard and impressive work! I wish you success in further improvement of this technology! subscribed on your channel ;)
Thank you!
That is just insane. Good job!!
you could use a camera to take a reasonably long exposure of the CRT screen to display the picture as is seen by eye in the video.
also it would be interesting if you tried to put the evacuation tube within the seal for the connections at the base of the CRT.
and if you're making another CRT project, you could try using those fluorescent green stickers for the phosphor, I think they're zinc oxide, similar to the P1 phosphor used in monochrome monitors but with longer persistence
Amazing project.

great channel! interesting that your image is essentially reversed compared to the proper CRT display. (the x is actually dark with a lit background)
just to understand how it works is awesome but to make it great job
Excellent !
How did you block the light emitted from the filament/cathode enough to not swamp out the phosphor?
Very fascinating.
