I started designing this for my dog Lu-lu. She has been a bad barker for a long time now. In the lounge room, eating dinner, starts barking... On the phone, she starts barking.. Just trying to catch up on sleep, starts barking.. Open a door, she starts barking. Close a door, open the refrigerator... and barking... I have created a basic PDF file with an attempt at a schematic. It essentially means reworking a wireless doorbell, modifying the receiver portion to drive a relay in self-oscillation mode, the coil feedback is then bounced to a secondary reversed of a mains transformer to get 9:240 step-up. The output of which goes to the collar to solve problem. Enjoy your quietness my friend.
