Homemade Cathode Ray Tube 1

It is a cold ion discharge that utilizes the rest gas inside the tube. Ions behave a kind of like electrons when the mean collision path length is below the dimensions of the tube. His ion source is a pointy tip inside a metal tube, I guess.

Looks more like negative ions than electrons. I can see that there still is a lot of gas inside the tube. You could add a magnetic lens for focus and see if it gives a sharper image.
Good experiment, good work!

its what J.J. Thompson used to figure out more on atoms he put a magnet on top and notice something i dont remember soz

man this is cool

Not much danger involved; there might be some X-Ray production from the glass, but the voltages involved are probably so low that it's insignificant. You'd see alot more green fluoresence from the glass if there was significant X-Ray production

Hello Nyle,
Could you explain whare are your electrodes ?Cathode is probably inside the small glass tube, but where is the anode ? Is it wound around thi small tube ? Best regards.

Not bad. This site is pretty neat for naughty webcam girls - _FUNDATERS.COM_

wtf is a cathode ray? lol. i just looked it up 4 sum reason. i obviously arnt smart as all u scientists here :) lol.

its DANGEROUS cause it leads to X-Rays!

that is awesome! i want to see a homemade picture tube.

You are a madder scientist than I! Cool tube.

Beatiful.
Please, mr Steiner can you tell us how many volt is on the cathode ? Any heating ? The electron gun is only 2 wire ? I make oscilloscope, but some problem with hotcathode. Maybe coldcathode is working.

Could this technology be used to render images of attractive women in scanty garmets someday? I am giddy with excitement.

Interesting, regardless of X-ray emission... I found that you can paint the TV image using ARM microcontroller - of course, the picture looks better in 32-bit mode. You simply just use PCM or PWM signal and 60Hz scan - you're ready.

How can I make this? Are those rare earth magnets? If not, have you tried rare earth magnets on this thing?

how did u remove the gases from ur CRT?

thats well built heres a question for u i have a liquid neon what is like a neon looks like lightning in a tube well is there a way i can make it sound active ? because i know i can make a standard L.E.D flash by wireing it upto my sub speaker and everytime the sub kicks in the led flashed but when i tried wireing up the liquid neon to it well it didnt work is there a way round this?

You are such a smart man, that I shouuld like to let you marry my daughtefr.

What kind of picture valve did you used? Is that tube homemade?

speechless

It would be great to see a TV image projected onto your tube.

Pretty dang cool!

Cool, thanks for sharing.

Wow, very impressive, what was the output transformer voltege?

Splendiferous.

The coil deflection was really cool.
