I use to repair crt's as a hobby and this video explained very well the essentials of how cathode ray tubes works. I loved it, hope you upload a second part explaining more stuff of this amazing technology.
At 17:20 you point to a wiggly trace in the middle of the screen and refer to it as "an AM signal". It's actually the colourburst signal that is "used to keep the chrominance subcarrier synchronized in a color television signal" (quoting Wikipedia) i.e. it ensures that everything is the right colour. Unless you're using the American NTSC system, in which case you have never seen the right colours. The colourburst signal isn't needed with monochrome systems.
This is my first ever you tube comment, and my first thumbs up. I really enjoyed your video. Perfectly explained and a treat to actually see step by step old school technology. I was exposed to theory at tech, but wonderful to see in real life. Tick of my bucket list. THANKS AGAIN
This is perfect time for asking my question which is How haigh we can increase the colored crt Anode Voltage before it breakdown how high xray energy we can get from color crt tube without breaking it can we use it as high powe xray tube source?
Friend , this the best vedio I am in 11th standard in second lesson of my chemistry we have cathode ray experiment and also cannal ray or anode ray experiment. In our labe ther no cathode discharge tube but I saw it in this vedio . Thank you friend ..... .......
12:22 no I think intensity of the Electron beam is change by applying controll Voltage on its grid plate just like controlling the transistor from its Gate.
This video sounds like my life 24/7...Please mention that the power inverter generates a high frequency noise and then run the audio through a low pass filter.... If you have tinnitus, this video is so incredibly anxiety inducing.
@@glasslinger Do I? Glasslinger, please don't take my diploma away, okay? It was a hard job to get it. I don't want to make you look dumb, though all the three main points in your reply can be confuted, even without a degree.
If an EMF was fed by multiple peltier modules attached to simple aluminum plate that can be put in the sun, against stove pipe, on car engine ECT... Have it feed into a cathode ray tube, make it switch on and off quickly, capture the BACK EMF the tube is creating.
hi bro I need help please :( How can I turn on the lights automatically when I get within 100 meters of my house? There is no internet connection in the area where I stay. How can I detect that I am approaching my house from a long distance and turn on the entrance way lights? please help anybody
For a while, I am used to bend beams of light within air, instead of electron beams in a vacuum tube. A small contraption does the job, when an attempt to violate Pauli's inviolable exclusion principle creates extra space within a confined piece of spacetime. Light always follows geodesic lines - aka spacetime-curvature.
Look how far screens have advanced since 1890... even to the point that video & images can actually be screened inside the human eyeball. Yet since 1890, electric cars and their power source has barely evolved at all; and are far too expensive to maintain and operate. Evolution for transportation has been suppressed intentionally because it would ultimately lead to free energy- the oil companies' nemesis. Go figure- follow the $$$. We aren't allowed to have the good stuff.
of course, those pesky oil companies... they wouldnt have any interest in a way of reducing oil consumption, so they could drill less, refine less, and charge MORE for producing LESS, of course not... no, they want to drill for as much as possible in the remotest regions, and make it as cheap as possible, so everyone can bathe in glorious petroleum products, an abundance of hydrocarbons... yknow, even if the energy were free, they would still require lubricants? insulation? plastic assemblies? or does this free energy also negate the need for such mundane essentials?
yay. yet another CRT video.. how... mundane. sorry. i want to see the POSITIVE RAYS. there are ZERO videos on POSITIVE RAYS. all we get is stupid animations, and a smattering of theory. not ONE GOOD DEMONSTRATION of POSITIVE RAYS. i was hoping, fingers crossed, that this may be a demonstration of POSITIVE RAYS. sadly... nope. whilst at first, teh construction seemed it may be possible, as the video progressed... nope. just a regular, if rather limited, CRT. ground well charted, material already covered... tired. stale. repetitive. there are THOUSANDS about plain old CRTs. yay. electron beams... same old, same old. almost more videos than CRTs actually ever made, it would seem. maybe being forgotten in this day of blue LEDs and laser diodes, but nevertheless... well documented. i want to see POSITIVE RAYS. and that may well lead to JJ thomson and the basic maths showing how the electron was proven to exist in the first place... WOW...NEW (old, ha ha... ) TERRITORY. an ALMOST UNHEARD OF SUBJECT... wouldnt it be GREAT to finally WATCH SOMETHING DIFFERENT?
@@andymouse not positrons. "positive rays". "canal rays" if i meant positrons, i would have said positrons. dont want to see theory, lectures, or yet another demonstration of flogging a well flogged horse like this one. i want to see "positive rays". as used by jj thomson to show the difference in mass of an electron versus the ionised nucleus of hydrogen.
@@paradiselost9946 Cheeky Cu&t..WHY didn't you just say fucking ION's then ? Dead simple stuff "Canal rays" are positively charged particles (ions) discovered in gas discharge tubes, and they were first observed by German physicist Eugen Goldstein in 1886. When an electric current is passed through a gas at low pressure in a discharge tube, two streams of particles are produced: the well-known cathode rays (negatively charged electrons) and a second, lesser-known stream called canal rays (positive ions). Neon sign technology simple and taught in primary schools. And yes I have done plenty of work in Mass Spectrometry both positive Ions and negative Ions.

I think the high voltage generator interfers with the microphone 😁

Wish youtube was there in our times. Rather than only 1-2 pictures. We could have learned so much from video.😢
Excellent video! Presented in a way that anyone can understand. Hopefully many others will see the value and also become Patreon supporters as I am!

CRTs are very interesting and you did a fantastic job of explaining them😊
One of the best vedios in your channel...congratulations.

Thank you friend .....

Beautiful video! Very instructive! I already knew all of that but I'm old. Younger generations needs all of this
Great Stuff Buddy

Great. Till I watched your video, I ever wondered what was the use of those electromagnets(deflection coils) in a CRT. Thanks for your video.❤❤❤❤❤
Very informative! Muchas Gracias!

He mentions this using a caption

That noice is messing with my fillings 😁
So I'm not the only 1 that noticed that. Cool vid just the same. 👍
Editing is awesome
He is learning new things everday in the journey of youtube 😂
The scanning signal is of sawtooth shape ( slow raise and fast decay ).
16:14 I am wondering why whole line are moving in Sine wave signal people do this same setup to make real sine wave on crt screen.
Nicely explained 👍
Great video, thank you so much. Well demonstrated and done
Thanks! Good explanation
Very interesting thank you for sharing this and all work the you put into your videos!
Appreciate the information mate.
Great video 👌
Love the intro
Thank You
I love your content.
You are the best knowledge humor presentational wise
@@mohamedabdikarim3128 thanks a lot!!!!!
😂 SPL Modulating. Question is, Can I use the CRT particle accelerator screen for X ray radio astronomy ?
CoolI look forward to seeing more on this
1:47 I think it was first discovered by jj thomson
for the fun of it, how about a video showing how you assembled that big board of boards behind you
please 😁
Thanks!
Thanks bro!
Damn editing skills 🎉
I wanna see CRT and vacuum tubes make a comeback
One note: in a perfect, complete vacuum, no rays will appear. It works only in partial vacum, meaning some very low pressure gas.
Rubbish.
@@andymouse I used to eat mice alive, so be careful.
@@baladar1353 SQUEAK!!! :)
A perfect vacuum would be ideal for the rays to travel. You need more education!

Love it
Can this cathode ray support SSD card?
4:07 it looks 😂😂
Where the hell is the TV picture on your experimental tube! CLICK BAIT!
CRTs remind me of Vacuum Fluorescent Displays
Very similar tech !

Have it feed into a cathode ray tube, make it switch on and off quickly, capture the BACK EMF the tube is creating.

My ceiling in my bedroom is painted with phosphor.
nice
more history lessons!!!
such as what happens behind the cathode in a CRT? you want history? look up "positive rays". beware, theres a very deep rabbit hole ahead...
cool
