Build Your Own Tesla Coil

screenbert writes "Ever wanted to keep stray dogs or neighbors from trampling your backyard, but just couldn't find the system to really deter them? Well this site shows how they built a bi-polar Tesla Coil system. I've always loved the Tesla coils on C&C when they'd zap the units as they went by. "

    Every college student knows that to keep your roommates from your food, you just poisen some of it, after the first couple of them die, the rest learn pretty quick. It may not be high tech but it gets the job done.

      In college I had a friend who's suitemate was always stealing food/drinks. Eventually they decided to started making special batches of brownies, cookies, etc. which had ex-lax, or other such extras in them. Everyone but the offending stealer knew not to eat them. I don't know if the guy ever figured it out or not, but it sure brings a smile to my face thinking about it now.

      It does work, mind you... don't use a very strong poison, but powdered laxative works wonders.

      Friends of mine laced a dozen muffins with it (added a bit of sugar to hide the taste) to deter someone who's been stealing their food, and that night they heard the toilet being flushed every 10 minutes...

      Works like a charm :)

    Before Slashdot posts stories like this, they should very expressly warn their readers about the dangers inherent in such projects. Although a simple Tesla Coil is not particularly dangerous, if a Tesla Coil is turned into a mobius strip and enough energy is put into it, a electrotemporal-topological disaster can result, plunging an area up to 5 kilometers around it into Dirac Space.

      Beause often this device also causes ontological collapse, causing the very Being-as-such of the destroyed areas to return to an essential, rather than an existential being. Now, normally, being and essence are two seperate things, and since to destroy one would be to destroy the other, Being-as-occupying in the way a city does can not be destroyed totally, and so even as one side is wiped out, the other can not be, so the city reasserts its ontological identity.


      Now, some people would believe that memory is just data reflected in a synapse. But really, memory is a process where the ontological throwingness-of-being of Beings is reassertted in the personal ego by reconciling somethings Being-as-such with its Being-towards-others. Butif identity and being are crossed, as they are in a Mobius Strip, they can be linked together, and thus annilated from the memory of Being-as-being-towards-its-own-reconcilation at once.


      So lots of cities have been destroyed with this weapon, we just don't remember them.

The spark would climb to the level of the hot dog hover there cooking the hot dog for a few seconds until the hot dog exploded in a shower of carbon and meat. It also detonated pickels.

    i take no credit for this, this is from UPL18, written by Jolly Spamhead, http://phonelosers.net In this article I'll show you how to make a very effective modem killer weapon, especially on crossbar phone systems (CPS). I take no responsiblity whatsoever if you kill yourself or get hurt in an attempt at trying to do this fucked up trick or for some reason it just doesn't work anymore as I haven't performed it since early 1998. A great person once said it is never too late to pass infomation on...so on wit the show bitch! What the fuck is this strange device? It's a Tesla Coil! Concentrated static electricity you f00l! The Tesla coil when properly used will generate litrally thousands of volts at very low amps. That just happens to be the right current to bake silicon chip cookies over a open camp fire strumming Bodycount songs! Construction: 1. Disconnect all phones from your line. Disconnect answering machines and any data-transmission devices. 2. Run a test on the coil and disconnect nearby grounded objects. (Lamps, stereos, TV's, Sex Vibrators...) 3. Connect one phone that you would'nt mind maybe having to sacrifice for the act of revenge.(It usually doesn't destroy phones, but people have told me they have seen them melt off walls!). =) 4. Connect iron or steel balls to the green and red wires of your connected phone (aka the biege box wires that go on the clips.) It and 12 terminals of your phone. 5. Put on a pair of thick rubber gloves (EXTREMELY IMPORTANT STEP HERE!) 6. Charge the coil to at least 10,000 volts. An ideal setting is around 18 to 19 thousand, but 10,000 will jump Ma-Bells line surge protectors and that's what we are trying to do here. 7. Hold metal balls in your left hand. In your right hand hold your cock and proceed to stroke firmly until climax is reached, then lick up the mess! Just fucking around here again! =) Just Make sure the balls don't touch each other ok? Great! When the coil is fully charged, clip the steel ball connected to the red wire to the base of the Tesla coil and hold the other metal ball as far away from the coil as you can. 8. Dial the offending modems phone number (OCI's fax # would be nice). 9. When you are connected, move the metal object connected to the green wire within 2 feet of the coils top. Don't be afraid of the little bolts of electricity shooting from the top of the coil...its only the stuff that hits poor hopeless saps like Amit Grover AKA Foreskin boy every once and awhile. 10. Within 3-5 seconds a huge bolt of lightning will shoot forth at the phone from the hand you are holding the balls in. Hold on tight cause it will feel like a load of ants! You will immediatly hear many strange occilations to the carrier on the phone. The last noise you will hear from the phone is a pop! That is the last cry of agony as the modem shuts down This is guaranteed to fry the modem, the computer and any peripherals connected to it like Scanners, printers, 8-ball porn cams.
