Computer control relays - Electronic Circuits Projects Diagrams Free

I have created a lab type power supply out of an old computer supply and would like to use it to control an airsoft gun mounted on a tripod. I already have the servos and a wireless camera but I need some sort of device that will allow me to switch the low current circuits on and off with my computer. Something like a board of relays controlled over WiFi.

Thanks everyone.

Also, my budget is around 50 dollars.

Sounds imposible for $50

what's wrong with the good old wire

Wire it and all your problems vanish. You can use a PC printer port to drive a current boost transistor for the relays. A wireless module alone is going to cost you 50 bucks or more for a pair plus code and peripheral hardware to drive it, and you haven't discussed range or environment yet.
