Question.... Isn't there going to be a problem with the 2 reflecting surfaces creating a corona effect like in air-couppled projection sets?

[rajithaify]

nice demo.. btw why didn't you just apply pva and fix the lens?

[wheelfan100]

I have a question why you need to put the lens on CRT instead of just putting on the TV with out the lens.

Cool demonstration. I would not have thought this to be possible.

I would have used foil backed tape around the edges. I think it would deteriorate slower than packaging tape.

Silly question i know...But does a CRT like that, hold a charge once removed from the case? I am just learning about old tv's.

[hellsmaw84]

its the flyback that holds the charge. old or new.

[smith123]

@hellsmaw84 Not the flyback, the tube itself does.

[WindowsAndMacintosh]

The CRT holds no charge... The flyback transformer holds the charge.

LOL, I think you need to brush up on your electronics a little bit bud...

[UX210]

The glass of the CRT, along with the conductive surfaces on both sides of the glass (lots of surface area) acts as a large capacitor which holds the charge. Flybacks do not hold a charge, sorry. The CRT glass acting as a capacitor also serves as a filter for the high-voltage.

[redSKORPION50]

Correct.

The flyback transformer is nothing more than a bunch of wire when its got no power on it.

[redSKORPION50]

Its not a silly question!! How else would you learn if you dont ask!! ;)

[1L6E6VHF]

Very impressive!

Do you replace the PVA or install any other bonding agent?

[peugteobike]

I want to learn to do this with CRTs

Great videos! I see on your projector that you made this on my birthday! Aug. 5
