“If your desk isn’t messy enough, then you must not be a maker” truer statements have never been said my friend. My apartment constantly looks like a giant nerd fight. This was really cool mehdi!
You guys have all taught me so much! Thank you Electroboom, Plasma Channel, Cody's Lab, Applied Science, Tanner Tech, Thought Emporium, Nurd Rage, Extractions&Ire, and Periodic Videos. 🙏 So smart. THANKS!🎩📚🦬
Nice work! From the amount of Plasma I would expect a pressure of somewhere between 10 mbar and 0.1 mbar. For electronbeams that are used (either in Electron Microscopes (SEM/TEM) or for Electron Beam Epitaxy) in Lab settings we usually have vacuums around 10^-5 mbar, since in those the electrons flow much easier and are well behaved so that you can control and detect them accordingly. For demonstration purposes a vacuum of ~10^-3 mbar should be enough, use some Argon to show the path of the electrons. Also if you use a Helmholtz coil setup you can actzally adjust the path of the electrons into a circle and use that to correctly measure the charge of a single electron.
@MUM!N You need a purpose build X Ray machine and a purpose build X Ray tube to get significant amounts of radiation. For example High voltage rectifier tubes are known to produce small amounts as an unwanted byproduct. Audio Tube Amplifiers are the most common type of Vacuum Tube Application today among very high power transmitter tubes. But there is no concern from those since they are not contained in a glass envelope but a water cooled metal jacket. Audio Tube Amplifiers pose no significant risk.
@@maxxiang8746 you are correct that is one of the main factors. Normal vacuum tubes often barely see 500V. So almost no X Rays. Seeing 1000V in a Tube Amp is rare. Highest I ever worked with was 450V which is not much in contrast to thousands of volts but still a change of pace to work with from conventional electronics.
Here's an explanation for the "clumps of gas" in the vacuum chamber. When pressure is decreased in cathode ray experiments (which you were doing by drawing the air out), the cathode ray tube goes from irregular crackling to a horizontal column that stretches from the anode to the cathode. When you decrease the pressure even more, eventually you get something called a Crooke's dark space, negative glow, Faraday dark space and striations. These striations are the "clumps of gas". There are many stages that correspond to different pressures though, so I've only just mentioned the first stage and the stage we're interested in. Also, I'm not an expert in this topic. I am just a high school student who came across electric currents through gases. Please do correct me if I am wrong!
In real crts, they build a negatively charged "tin can" around the entire thing. This forces the electrons into the middle, meaning that, depending on the voltage of the "tin can", you get more electrons exiting the gun.
@@brokentos4546 the conducting metal inside the CRT is where the +25 kv is applied. It sucks the electron out after they hit the phosphor. The xray are stopped by the lead in the glass. The focussed electron beam is created by the succession of metal plates in the electron gun, including the focus control with a voltage of about +8 kv.
I had the same though and then I went to remember that this is a desk of a guy who tests his home-made vacuum chamber without even having a proper eye protection and the only method of testing high-voltage devices he know is to do it with his hand. That globe placement was pretty safe for his standards.
Like the scientists working on the Manhattan Project. "Could this set the entire atmosphere on fire?" "Why research, when we can just build and see what happens!"
@@MegaTechno My logo has had a blue to light blue gradient and MT letters since November 2016 (earliest Wayback Machine capture of my channel with the old logo is from January 2017).
You can greatly improve the seal on your vacuum chamber by wiping a thin film of Vaseline around the lower rim of your clear container, laying a wet ring of RTV silicone on the base, and gently pressing the container into the goop. The Vaseline prevents the RTV from bonding to the glass. When the RTV cures (give it a full week), remove the container and wipe all the vaseline off both surfaces. You'll now have a custom-made airtight gasket.
9:13 I believe this is the effect also seen in the Franck-Hertz-experiment. The electrons get accelerated and gain speed (kinetic energy). Once this energy is high enough the electrons can give that energy to one of the remaining air molecules exciting it in the process and making a glow. The electrons are now slower since they gave away the energy and they get accelerated again until they can give their energy to the next air molecule and so on and so on.
If you're curious, the source of these x-rays is the high energy electrons smashing into the anode disk and losing their energy rapidly. This rapid loss of energy is released in the form of high energy photons (the x-rays). This phenomena is called "bremsstrahlung," or braking radiation. I worked for 5 years with a Van De Graaff positive ion accelerator that needed lead shielding to protect against the braking radiation, since positive ions accelerating in high voltage (even at high vacuum) will ionize residual gas particles and release electrons that in turn accelerate backwards through the high voltage into the accelerator itself, creating x-rays.
@@dogwalker666 You're gonna have to explain this one to me. X-rays are uncharged so why would they need any kind of ground? They're unaffected by electric potentials. And I thought CRTs didn't have much of an xray problem because their electron gun wasn't at a very high voltage, but I don't actually know much about those so that's more of a guess.
@@ArchangelUltra Thanks I was wondering what that phenomena was. Now I'm going to dive into a Wikipedia rabbit hole. See you guys on the other side. o7
I love you man - I have a presentation tomorow on cathodic rays and I just understood now, watching your video, how the wind thing works - i send you lots of positive ionised good vibes from Brussels - cheers
@@arthurizando I wouldn't use the term "Strength", also I would add: divided by distance². For a X-ray sources mA·s and KV are commenly used for driving the tube. mA·s = current * time and KV is obviously voltage. mA·s is the main way of controlling the amount of X-ray photons produced by a tube while the voltage increases the photon energy, measured in KeV (electronVolt). The voltage actually also has a huge effect on the amount of photons so mA·s has to be lowered to compensate. However, X-rays with higher photon energy are actually less absorbed in a body compared to X-rays with lower photon energy. If someone wants to see soft tissue better compared to for example bone it can be useful to lower the voltage a bit. This is a way to control the contrast in X-ray imagery. You can also take images with MeV equipment used for radiation therapy, this however created images with extremely low contrast compared to normal X-ray equipment because a lot of the X-rays will simply pass through the body without interacting at all. So "Strength" doesn't really say much in x-ray physics! Obviously the physics and biological effects behind X-rays are quite a bit more complicated. But my knowledge is incomplete and a bit rusty so to say.

Two things, The symbol for a diode is a artistic representation of the old style vacuum diode where the triangle is the electrons beaming from the cathode towards the anode. You should have placed a piece of fluorescent/phosphorescent material behind the washer for a nicer effect.
The third problem is having a washer that wide. Typically in CRTs the anode is made from a sheet metal welded into a shape of a cylinder, and the path of electrons has to be narrow to increase efficiency

@@pcriged you’re sort of right. most x rays can arrange from 70-400 KV. You can seriously create some decent x rays. I know this because I graduated from radiology, and I work with x rays.

There’s reasons why a lot of scientists don’t play with this anymore. X rays are very dangerous if you’re not careful enough. Seriously kids, don’t do this stuff at home, not worth getting cancer over this
I wish you had a phosphorus plate to see how many x-rays you were getting both ways of energizing your cathode ray system. I built what turned out to be more than a 2.3 million volt voltage multiplier double marxx generator combination. Had an old civil defense radiation detection kit and started noticing the radiation dosimeter were constantly pegged even after being reset. Radon? no check for that regularly. Ultimately it turns out that high voltage Spark x-rays ,tungsten and beryllium are not things to keep in close proximity to your marxx generator.

It would be really interesting if you could do the double-slit experiment with electrons in a cloud chamber. Would the alcohol vapor cloud cause the wave to collapse and behave like a particle immediately causing two vapor trails (i.e. similar to placing the observation screen extremely close to the double slit) or would it show trails of vapor disruption that align with how the interference pattern would form?
Well yeah, vacuum tube with two terminals (anode and cathode) is called diode. Add a grid and you have a triode. Add screen you get a tetrode. Add suppressor and it's a pentode.
Can relate, I have 3 desks pushed together, plus a small table and a media console full. Edit to add: And also the floor in the room with the desks and table is covered too.
An interesting addition would be adding something with phosphor to see if you can get the beam to strike it and make it glow. In a tv screen, you don't see the electron beam at all. You see its effect on the phosphor. I think I would set up the cathode and the phosphor and then move the anode or washer around to see if you can direct the beam. Then you can also bring in a big magnet (assuming all the other parts are glued down somehow) and move the magnet to see if you can deflect the beam.
my table is so messy that gravity is pulling the mass of stuff into a planetary system im sure their is also black holes forming coz if i put something on it i loose it forever

It makes me feel nervous.
Mehdi: *makes cool schematics of electronics*
Then Mehdi: “Ok let’s check it out”
After that: “I’m such an IDIOT”
This is accurate
I wish you had a phosphorus plate to see how many x-rays you were getting both ways of energizing your cathode ray system.
I built what turned out to be more than a 2.3 million volt voltage multiplier double marxx generator combination. Had an old civil defense radiation detection kit and started noticing the radiation dosimeter were constantly pegged even after being reset. Radon? no check for that regularly. Ultimately it turns out that high voltage Spark x-rays ,tungsten and beryllium are not things to keep in close proximity to your marxx generator. As a machinist I had worked with lots of metals and had various chunks.
"Why reasearch when I can just build and see what happens" EB - 2021 Nicest quote
if marie curie would say the same 2021
I heard 'Cathode Ray' as 'Catholic Ray.' High voltage holiness.
I would be toasted if I encountered Catholic Rays lol

I feel like he's the most educational and messed up person at the same time
Looks more like a creature than my drawings.
I feel the educational value is enhanced by his willingness to hurt himself and now even exposing himself to radiation. 19th century and early 20th century scientists would salute him.
too many xrays
I was working on a old zenith crt and was trying to describe to my wife how the fly back transformer works, so this helped I think. Love your content.
12:00 We Melee players still have an application for cathode rays: getting all of our exercise from carrying CRTs around for weeklies.

there was an episode where his sister send the hair dryer to fix it for her. it may be that hair dryer.

"I'm gonna glue this silicone with silicone."
Edit: spelling.
I used the power of stones to destroy the stones
silicone*
in German silicone is Silikon and silicon is Silicium.. so people have a hard time understand the concept of Silicon Valley..
@@olik136 Nein. Silicon (Silizium) ist das Element und Silicone (Silikon) die Dichtmasse. Es heißt Silicon Valley nicht Sillicone Valley --> TLDR: No, nobody has problems with the concept, if somebody in Germany has problems with that its mainly because they dont know the difference between silicon and silicone.
@@olik136 And I originally thought that "silicone" was the alternative spelling of "silicon." Now I know better.

Also Mehdi: X-Rays are the dangerous part.

And a particularly energetic one this time. I like it.
He actually says "High!" as a reminder to self of the painful pleasures ahead.

I feel that.
There is no earthly reason why this guys gags should still work and still be so goddam funny. I attribute it to genius. Comedy genius combined with electronics genius. Who woulda thunk it. Kudos man!

You'r daughter will probably be into electrics things.
9:21 Aren't these "clumps of energy" just the equivalent of the disc's in the Franck-Hertz experiment?
It would be really interesting if you could do the double-slit experiment with electrons in a cloud chamber. Would the alcohol vapor cloud cause the wave to collapse and behave like a particle immediately causing two vapor trails (i.e. similar to placing the observation screen extremely close to the double slit) or would it show trails of vapor disruption that align with how the interference pattern would form?
It would cause the wave function to collapse
@@alexmijo If you believe in such nonsense as the wave function collapse

His desk is messy at the beginning, then he cleans it up to work on this project, and by the time he’s finished it’s a mess again. So accurate!! 🤣
11:17 oh..OH almost a crazy genious laugh right there
bruh i thought at 2:00 an explosion acctally happend XD mehdi's editing skills are great
He's literally making a vacuum tube without any grid, I love it
He needs to add a grid and use it as an audio amplifier from his lighter mic.
@@kendallemory8455 yes
Or any vacuum.
The vacuum is pretty bad though
Well yeah, vacuum tube with two terminals (anode and cathode) is called diode. Add a grid and you have a triode. Add screen you get a tetrode. Add suppressor and it's a pentode.
"What? That's how engineers work, or makers or whatever"
Can relate, my desk is a mess.
Yup - so many projects and junk - not enough desk and bench space! 👍😁
Can relate, I have 3 desks pushed together, plus a small table and a media console full.
Edit to add: And also the floor in the room with the desks and table is covered too.
Or students in the middle of exams...

@@Misack8 Oops, forgot the floor (also covered in stuff). Hey, I cleaned the media console off yesterday!

5:25 The most amazing thing is that he needs a hair dryer.

"I'm going to glue this SILICON with SILICON"
[inception intensifies]
That's SILICONE
I used the silicone to glue the silicone.
*sillicone
We heard that you like silicone, so we glued your silicone with silicone so you have enough silicone in silicone
1:17 but if an electron experiences more force towards up then it will go more up than centre and nsow has more down force. So it will go in a SHM.
That's really stupid assumption
An interesting addition would be adding something with phosphor to see if you can get the beam to strike it and make it glow. In a tv screen, you don't see the electron beam at all. You see its effect on the phosphor. I think I would set up the cathode and the phosphor and then move the anode or washer around to see if you can direct the beam. Then you can also bring in a big magnet (assuming all the other parts are glued down somehow) and move the magnet to see if you can deflect the beam.
12:08 - It's gonna fall, I tell you!
I can’t complain about the messy table, mine is so messy that I just held something in my hand while soldering it.
my table is so messy that gravity is pulling the mass of stuff into a planetary system im sure their is also black holes forming coz if i put something on it i loose it forever

I am thinking about dropping out of school to focus on my career as a star on TH-cam. I already make a lot of money on TH-cam. School bores me so much. I need more opinions and since I don't have any friends, I gotta ask you, tene
@@AxxLAfriku Don't think anyone cares, conehead.
I once saw a vid of someone who built his own electronic microscope, I think it was applied science.
0:37 "From what I understand"
Ah, this is going to be interesting.
100% true
If invert the polarities of the electrodes, you will create an "Anode Ray" and a purple glow will emerge from the hole in the cathode (Originally the anode). Great video as always!
I can’t believe that fake explosion actually scared me for a second...
It gets me every time.
It’s mandatory
