    Hey,
    I'm making a remote control siren in electronics at school - it is running off USB power (that's all going), but I need a cheap way to switch it on and off though a wall. i have a couple of old phones at home that i could use, but i don't have to use them

    Try getting a wireless doorbell at a local hardware or home improvement store.
