Secondly, the headset which he utilized with the preliminary hack has gone out of production. He selected a new model, as well as the assembly video (embedded after the break) which he made is a treasure trove of finest methods to utilize when hacking consumer electronics.

The collector of the transistor is then linked to the garage door opener, together with a typical ground connection, enabling audio from the headset to trigger the transistor to open the door.
