Holy Crap!!!

Unread postAuthor: cardinals08 » Sun Feb 19, 2006 11:32 pm

I was playing around with the thing found here >>>http://www.scitoys.com/scitoys/scitoys/electro/electro4.html<<<
I had the foil on my Emmerson 20" flat screen TV, if any of you have seen it you know that it has those 3 jacks in front for plugging things into it such as Play Station 2. And around the colored plastic is metal. Well anyway, I had my hand on the can that was connected to the wire on the foil, and I had my other hand on the power button turning the TV on and off to create the voltage jumps to make the thing work better and get sparks over and over, and little did i know my thumb had gotten really close to those jacks on the front, and the next time I turned the TV on, ZAP!!! You wouldnt believe the shock you can get from the static electricity off of the TV when you add aluminum foil and wires and cans. That thing sent the shock through both my arms and made them contract and my arms flew up about a foot. I was thinking about having my friend come over and hook the thing up to my bedroom door and call him in when the door was closed, but nah, Im not that mean, Ill save that one for my sister, JK :D
Hey, maybe this thing can be modded somehow to make an ignition, it wouldnt be very portable though

Why would you go through all that trouble to make a TV-static-powered ignition system :D ? You got shocked because the cans (as well as the cathode ray tube) have some capacitance due to their geometry and material.
So there may not be a lot of energy on the screen at a given time (i.e. you don't get shocked just by touching it, do you?!), but that energy gets stored on the inside of the cans (also maybe between the screen and foil, since there's a air there). You can make more efficient capacitors from stuff around the house. Just google Leyden Jars or notebook capacitors, etc.

Were you shuffling your feet around on carpet? You could have had a charge built up in you, and when you got your finger close enough to the ground, (the metal around the tv jack) you could have discharged yourself. You only have to be within 1/4" from any kind of ground. The ground in the RCA jacks do there job very well through the tv.
