Looking to build a battery powered small light (LED?) that works on a winding/pull cord. Alight until cord winds up.
I'm an assemblage artist and I'd love to begin putting electrical components into my art pieces. My first idea is to back light a piece with a small lamp which the user has to pull a cord to turn on, and then only lasts a short time (20 seconds?). This would need to run on a battery of some sort which could be changed when it's dead.
Can anyone point me in the right direction? I know VERY little about wiring/electrical - only enough to rewire traditional lamps or light switches in the home.
Thanks so much!
