Not sure if this is in the right section, sorry if it is not. But it is for a replica prop. My Tardis. I have a sound card with the sound of the Tardis on, (it is part of a sound effects keychain). I have it set up to a subwoofer in the floor of the tardis, and when my kids go inside they can push a button and the sound effect plays and the floor vibrates (gives them the feel of moving). Anyway that is all well and good, but what about me?.. At night when I take my dog out I often look at the back of my yard and can see the outline of the Tardis and it gives me thrills. What I would like is to be able to also remotely activiate the sounds, maybe a little thing on my keychain or something, that I could press at night and enjoy the thrill of seeing and hearing the Tardis materialize in my own back yard.
so here is what I need to know, how do I make a manual and remote switch? I have no idea how to figure it out. I know its possible, because nearly every applaince has a on/off button and remote.
Can someone please help.
Thank you.
Jamie.

PS, the power source is battery, (just incase this matters much). thanks again.
 
How many volts is the battery? If it's a car battery, get a cheap car alarm with a second channel on the remote and use it to power a relay to activate the sound board.
