REVOLUTIONARY! NOT Just a Simple Tube! From Cathode Ray to TV?

[@alfonsotoledo8009]

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.

I think the high voltage generator interfers with the microphone 😁

[@stevegreen5358]

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

[@IAmAnAlbatross...]

Wish youtube was there in our times. Rather than only 1-2 pictures. We could have learned so much from video.😢

[@xenoxaos1]

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.

So I'm not the only 1 that noticed that. Cool vid just the same. 👍

[@Grobotron3K]

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!

[@iota_i_1]

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 ..... .......

[@davidwitten2746]

Excellent presentation! Clear, concise and appropriately complete. Thanks so much for making these!

[@drsaif343]

One of the best vedios in your channel...congratulations.

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

[@therealchayd]

Very informative! Muchas Gracias!

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.

[@rahulbhaskar4179]

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.❤❤❤❤❤

[@omsingharjit]

1:47 I think it was first discovered by jj thomson

[@NilsRohwer]

Great video, thank you so much. Well demonstrated and done

[@JushuaAbraham-sj2xl]

The scanning signal is of sawtooth shape ( slow raise and fast decay ).

[@baladar1353]

One note: in a perfect, complete vacuum, no rays will appear. It works only in partial vacum, meaning some very low pressure gas.

[@andymouse]

Rubbish.

[@glasslinger]

A perfect vacuum would be ideal for the rays to travel. You need more education!

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?

[@ANONYMOUS-hf5gr]

Appreciate the information mate.

[@sudhanshushekhar6920]

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.

[@nonsensicalnonsense4260]

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.

[@wireless80211x]

😂 SPL Modulating. Question is, Can I use the CRT particle accelerator screen for X ray radio astronomy ?

[@ZoeyR86]

My ceiling in my bedroom is painted with phosphor.

[@muhammadaleemadil]

thanks

[@debrainwasher]

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.

[@glasslinger]

Where the hell is the TV picture on your experimental tube! CLICK BAIT!

[@crossmariane9668]

Love it

[@bepstein111]

more history lessons!!!

[@paradiselost9946]

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...

[@samircmps7260]

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

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.

[@paradiselost9946]

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?

Want a video on how to use a parallel interface 2.4" or 1.77" TFT display with Arduino Uno

[@tamastokai1477]

clickbait.. :)

[@paradiselost9946]

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]

Positrons are used in medical machines, try that area for your research.

[@paradiselost9946]

@@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.

[@andymouse]

@@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.
