I'm trying to make a small emp gen that could disable a small device for a project (Next years Science Fair) but have little idea how to make one. Could someone help me out?

Umm, well one of the main rules of the site is not to ask how to build something from scratch, but asking for help with an already-built project (such as how to improve HV output) is acceptable.
that said, I did build a small magnetic pulse generator which permanently discoloured the screen on a CRT, from 1 foot away. It was built using a bundle of ferrite rods secured with tape, then wound with about 100 turns of fairly thick (24ga) wire. This was then connected to a small capacitor bank.
Also its worth looking into the effect of some cheaper calculators (non solar even) being affected by the intense light from a camera flash.

I'm really sorry I posted this in the wrong section I'm new here.
Hmm, I think you made a very good elecrtomagnet. And a big EM pulse to disable a CRT
I have been doing a lot of reaserch about EMP's and I found this PDF File...(see attachment)
I have improved on my first EMP generator which didn't work (that's why I'm here) to making a small one from a Photo Camera Flash which produces 330 Volts from charging a 120 uF Cap but i now need a much larger capacitance Cap to make a better Generator. So I'm still trying. If I finally make one I'll then try to capture the EMP and convert it back into electricity.
Thanks a lot for your help. I hope I don't get in trouble for posting this here. Again I'm really sorry I'm new. ]1182911901_840_FT26985_emp_gen.zip[/file]

The projects section is not the place for this thread, and there is no place on this forum where someone will tell you step-by-step how to make an EMP device. Please use better judgement in the future, and make sure you understand the rules of this forum.
