A Vibrating Deaf Dog Caller Collar <5$

Step 8 Build Receiver Unit

On the back of the battery holder glue or hold on with elastic, the circuit card.

Reconnect the battery wires as per your wiring diagram from step.

Tape up the battery holder/circuit card unit securely to protect it from weather.
