I hacked one of those singing bird motion detectors yesterday and it seemed easy enough. Today I decided to hack one of those croaking frog motion detectors. The circuit is virtually identical but in this video I show you how I identified which terminations to use to connect the vibrating motor. I left the speaker in circuit in this hack so it still croaks when it detects motion. All I have done is added the vibrator. The croaks are shorter in duration than the song of the bird so there is less time for the motor to vibrate and it is less active than the previous hack, but it still works. With a little work it could be made more efficient, the speaker is quite heavy and the plastic casing could be discarded. In fact you could just save the circuit board and motion detector and dump the rest. The result is one of those vibrating bugs that reacts to motion. The vibrating motor is from a toothbrush, but you could get similar from other sources such as pagers or mobile phones. If you look at my playlists you will find my other vibrating bugs and also a couple of videos on disassembling vibrating toothbrushes to salvage these motors.
