This video shows how to make the bread circuit for 555 timer based Door Bell.

Full Project :

The schematic was reverse engineered by Julian Ilett from a kit.

I was inspired by his video and made this project on a breadboard.Then I make a PCB for the same circuit.
You can download the PCB from the following link
