I call my butler in the morning and tell him to turn on my shower and PC while he cooks my eggs. No soldering needed! Fully remote for on AND OFF functions too. Unfortunately he takes more than 3 AA batteries to keep running yet ....
Where is "here"? .. give us a clue and you might find what you need.
Sounds like you may need some lessons in how to use the web, particularly google.
Maplins:
Door Chime @ £10.99 (going to need to step down the voltage or run it on batteries.
5v Reed Relay @ £2.56
Build cost ~ £15 if you are going to build a step down circuit for the voltage too.
better door chime from Argos @ £7.99 runs off three C type batteries = 4.5v
build cost ~ £10.55
On ebay you can get them for a fiver or so if you want to wait for one to arrive from Hong Kong.
Crazy
sweet idea! I may have to incorporate something like this into my next buildup
