Wireless switch?
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.

Answer 9 years ago
I have to fire it when i choose, no timer

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
Answer 9 years ago
That just might work. I just don't want to be right next to the thing
Answer 9 years ago
oh you can be 1-10 ft away but the futher u are the more powerful of a ir you need

It might just be easier to run a very long wire.

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