Wireless switch? Answered

I need to learn how to build a wireless switch that can turn something on like lets say a coilgun. I need it to be wireless so that i can stand back behind cover and fire my coilgun and do other things without harming myself or my classmates.

I have to fire it when i choose, no timer
I dont know about infrared, i can consider using an old tv remote
It cant be plugged in, it has to be 95% portable

well u could make this and have a toggle switch that turns it on and off then in stead of the led use a relay use this as the triggering yuo can  put it in a little box that you but battier power to it then it will fire the gun
the down side a tv remote can fire the coil gun or any remote control that's y i asked if there wass any infrared interference


and i wold suggest a height power infrared light the one that i have on there might work but you cant stand to far back with a height power one it will b about 10ft

And much more reliable (read safer). A home brew wireless switch maybe sensitive to the high power magnetic etc.
