Television-controlled alarm clock

Use the electrons from your television and two empty cans to make your own alarm clock! Tape a piece of tin foil to the screen, attach an electric wire to it and lead it to an empty can. The other can is attached to ground (in this case a heating pipe). The thing to open the can with hangs between the two cans.

Thats Awsome! I bet none of you people could think of that so dont even say its ridiculous because obviously he/she is smarter than you...

the 60kv does not come out of the wall. It comes from a flyback transformer inside the TV that steps up the current. Thats why TVs create a static charge. Like a small spark that jumps from you finger to someones hand is already thousands of volts of electricity. Just not at very high amperage.

So what anonymousburn said is true.

@RavetodaGrave Yeah I know that.

That would actually work! He is using some the high voltage from the screen; being extracted reactively. Even though the high voltage is DC, it is modulated to some amount from the scanning and the constant change of contrast in the pixture content.

I worked in TV design some years ago, and would have never thought of doing something like that! This type of thing is also transmitting a lot of RF radiation in to the room. Normally nobody puts large piece of foil accross a TV CRT like that!

@AtvProjects Hi, You can actually hook it up to your sattelite ( if you have one ) and it will tell you if its lightning. :)

WTF (*_*) LOL

[suraj0921]

it's good but instead of tv can't we put something like a cell(high voltage) or something

at 0:27 whats with the wire heading back around the wall towards the tv?

Interesante, aunque no precisamente útil, pero no es fake, tiene principios físicos válidos
