Television-controlled alarm clock

[jerryg50]

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!

just by a alarm

[TheEdtronic]

good idea...!!!!!!!

[jojotaekwondo]

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

[yudiweb]

WTF (*_*) LOL

[suraj0921]

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

[ticjosh]

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

[alfaygamarcos]

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

[Karlfalcon]

A lightning bell. I love it.

[AtvProjects]

lol cool but what would you use it for?

[prozacgod]

Ha, Amazing - classic, Props on the ingenuity of the hardware franklins bells is always a nice demonstration

[glock21cal45hp]

nice. but isnt it easier to get an alarm clock instead?

[LPLC1978]

Clever !!

[RHoppenreijs]

zo die man heeft ervoor geleerd... dus dit doe je ipv tv kijken?! wanner staat het filmpje van vandaag er trouwens op?

[coolio444444441]

THATS AWESOME!!!!!!

[anonymousburn]

You best becareful, Tv tubes can generate up to 60'000 volts that can really hurt your hand if you ever touched those cans the way you connected to the ground.

[casanoval33t]

hmm ofcourse :) keep dreaming pls... it is imposible that 60kv comes straight outta your wall without burning the transformer. sure does ;)

[philcotube42]

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]

@philcotube42 it only takes .6 amps across the heart to kill yeah?

[atomic1234567890]

@RavetodaGrave .03 if across the heart i think

[DKFILMS12]

cool and creative

[rynprov]

Now if you program the TV to turn on say... 8:00 am with the volume to the lowest, would the ringing wake you up?

[psion0027]

or you could just have the volume up really loud and wake up to seseme street

[CaptainCropper]

Heh heh, pretty good :o)

[codediamond]

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...

[Scott00]

That's the most ridiculous thing I have ever seen.

[grizzly6922]

lol creative... yet sumwhat worthless cool tho
