What isn't? :D

Apparently all manner of things that walk, crawl, swim, and slither, that can kill....

Maybe you guys don't get guns because based on watching National Geographic, it seems all you have do to kill someone is go outside, grab anything moving, and toss it at your target...

I mean poisonous jumping ants?!?! :scared:

They should get guns to help fight off all the dangerous creatures that roam the streets...
 
I ve actually calculated an EMP strong enough for a whole block.
I aint big but it requires a pipe bomb :whistle:
 
I'd be more interested in reusable types of EMP... But I guess such calculations are still fun for theoretical exercise.
 
A multi-kilowatt SRSG Tesla Coil fed in to a resonant 1/4wave antenna will radiate enough EMI to disrupt most radio communication within a mile or so. The only reason normal TCs don't interfere too much is the spark discharge makes a poor radiative antenna. If you capacitively couple log periodic antennae in to the spark gap circuit you can boost the EMI production exponentially. Most spark gaps radiate from the tank resonant frequency up to about 10GHz or so, but again have poor antenna transmission. If I run a small 100W SGTC with long enough leads on the spark gap to resonate at 2.4GHz I can knock out WiFi within a 1/4 mile radius.
 
i finally have a purpose on this fotum.yea me.

im a cell tower hand.

you dont need to jam everything.just the cellphone frequency ranges by being stronger than the tower signals.
like a cellphone with an amplifier sorta thingy.strongest signal blocks all others like a floodlight.
the engineers even say think of it as light.

Yeah I think that's going to work but i won't test it my tesla:whistle:
I'm like more the high impuls way that's able to destroy ICs

There are lots of -unsafe- methods to disable microchip ICs like a high energy microwave burst, the hard part is finding ones that are safe to people.

You wind up with a large device that uses a tremendous amount of power and a feedline to direct that energy at the target. There is not much way around it.

This all gets away from the topic of phone jamming though. Cell phones use a spread spectrum type of communication mode so a simple power oscillator running at a defined frequency won't jam the signals at all. You would have to cover a frequency range with random noise to get any real effect out of it.
 
the random noise could be an atennae that puts out a range in those two main frequencies.

kinda like a floodlight at a campfire.thats how you get the efficency to make the object as small as possible.

or you could ddos the tower.by having an app that dials over and over different numbers jamming the local telco tower sights.
 
who knows there might be a diode that puts out one of those two frequencies.jam it in a lazer and burn out cell tower antennaes just by pointing it at them.lol.

im kinda bsing on that last part.i doubt they make a diode but not sure.

Doubt that would work.. Because to have access to my local phone tower I would need to be on the same provider as the phone I wanted to jam, Not only would I have to have paid for credit the minute they pick up on me wasting resources they'll just kick my number.. I also doubt 1 phone on it's own would be able to take down a whole tower. Not only that, If I started doign that, I'd be asking to get arrested.
 
cell tower ususlly have three sides.a.b.c.
it would only tie up one antennae on one side but that would be the same antennae everybody in your local would be using.

anyway the floodlight idea would work better but would get kinda warm when in use.
