Step 2: The Idea

Picture of The Idea

EDIT: I recommend  you add a power switch between the center tip31pin  and the negative  circuit contact, the circuit loves to eat batteries!

The tip31 can be replaced with 2n3055 :)

So this will be my first real attempt at this. Is there any way that you could give the name and model of the wireless doorbell that you used? Perhaps you can provide better pictures now more clearly showing where things are connected on the transmitter?
