Electric dog anti-bark (bark control) collar

(Reverse Engineered Schematics)



Schematic of an electronic dog anti-bark (bark control) collar. Cheap product from China. It runs on a small 6V battery and it is controlled by an unmarked integrated circuit. When the microphone detects the sound of barking, it warns the dog using a sound from a piezo loudspeaker. If barking continues, it warns the dog using an electric shock. The required voltage is provided by a transformer.


Testing the electric dog bark control collar using a neon lamp.


It gives mild electric shocks.
