This is what the net is for.

A website with all sorts of cool how to stuff, how to make hueys black power tazer glove;

Tazer Glove - Instructables

Not that cool but it can be amped for better effect, metal studs rather than foil, a better glove and so on.

How to make a grenade;

HIGH_EXPLOSIVE grenade step 3 ITS DONE - Instructables

A pepper bomb;

Pepper Grenade Canister/ Bomb - Instructables

And last but not least... how to make a lazer weapon... a real one that sets things alight;

Laser Flashlight Hack!! - Instructables

This one is cool, depending on the range it emits I was thinking about making a good 10 of these prehaps rewiring the on button of the torches to a more trigger like switch so they all turn on at once, then having them all pass through another lens to magnify and focus them. If one can pop a ballon and start a fire ten would be good enough to use as a prop in a star trek play.

Tesla turbine anyone?

Build a 15,000 rpm Tesla Turbine using hard drive platters - Instructables

An NES MP3 mod?;

NES Controller MP3 Player - Instructables

Alot of these would do well at a May Day rally or something. This is why I like a bit of tech, modding things making something out of nothing.

Another...

Really thought about making that Lazer thing but I've seriously been weary of things recently and going to maplins to buy all sorts of equipment could see one of InI go the same way as that brazilian guy, no joke. Talk to me about there not being a problem, gotta watch out buying electrical equipment in case I've got a beard and look like some sandman they've gone and pissed off. F'in idiots. The Lazer thing is cool cause you could buy a whole heap of diaodes (lazers) and hook them up to a car battery, make it into a lazer screen, aim it at a disco ball? Some kind of lazer security device... OR... you could transmit music down it, set up a reciver at the far end and make a wireless player bounce the signal about in a display case with mirrors and stuff as a music player.

Ok... seeing as I'm all in the mood now, might as well waffle...

HOW TO SETUP AN INTERNATIONAL PIRATE RADIO STATION.

This is another haphazard idea of mine. Will glaze over it, see if anyone knows about this stuff.

All these crappy pirate radio stations sit in some rented room with a transmiter somewhere and an ariel somewhere else or something to avoid the watchdogs. They clock onto the signal and take out either the ariel or the transmitter if you dont play Operation Trident adverts every 15 mins and talk about issues in the community (not joking). So what if you were to create a network of transmitters and antenna around London to cover an entire area?

You have one set up, all the equipment and so on playing out over an area. What you do is set up another toward the end of that radius and another and so on throughout London. What you do is transmit the signal to each. I'm in North London but am playing to a signal Lion 99.2 FM which is then being picked up by that next set up which then plays and bounces off to the next one. All are picking up on the radio themselves, playing it to itself and transmitting it. Now you don't want to be around, forget getting caught right? You can either prerecord (lame) or you can have one well hidden setup hooked upto the net. You can be miles away, even in another country holdig a chat show sending it out over the net to a network of boosters in London, could even have a few up North or.... get real smart and have an international pirate radio setup where another crew can simply tap into the signal (logging onto the net to air their show) to have it played out via the same network.

Its only a theory but I don't see why it shouldn't work. You'd have to have the net well secure hide the IP address and get techy on that side of things so they cant catch you.

Will post on my ideas on making a force feild later .lol.
