How to Make a Vibrating Dog Collar

Build a dog collar that has a switch to activate it every time your dog makes a loud-enough noise. When the collar is activated, the dog becomes distracted by a buzzer made from two pager motors. These motors are most effective when positioned near the throat of the dog. Make sure to test the device every so often (not on the dog). Also, do not put it on the dog when the dog is in noisy surroundings, since this can backfire by making the dog feel threatened by loud noises.

Instructions

    • 1

      Buy a momentary voice-activated switch that is normally "open." This means that you can buy a special circuit where the switch is off unless a sound turns it on. When it turns on, it will trigger whatever device it is attached to and turn it on. Encase this circuit in an appropriately sized PVC pipe joint for the circuit you are building. Remember to include space for the battery housing in the pipe joint.

      Attach a microphone. If you do not want to spend a lot of money, use a speaker from an old pair of ear buds as a microphone and solder it in place where the schematics (see Resources below or with your specific circuit) indicate that a microphone should go. Buy a circuit with the microphone already attached if you are not feeling up to the challenge of soldering the microphone onto the circuit board.

      Attach the "buzzer" to the output side of the switch made from two pager motors wired in series (one right after the other, in a row). Make sure that there is enough wire to run the buzzer to the other side of the collar, where the noise from the buzzer itself will not trigger the switch to turn the buzzer, which makes more noise and keeps itself triggered in a vicious cycle. Glue the two motors together so that the tips of the motors protrude outward.

      Cut an old marker tube the length of the two pager motors as they are glued to each other. Tape the wires to the inside of the marker case along with the central part of the motor. Wrap the tape around the marker case.

      Hook up the vibrating dog collar to the batteries. Test the circuit by making a loud noise to trigger the buzzer.

      Attach the buzzer to the dog collar and the rest of the circuitry to the opposite side of the collar. Duct tape everything in place to add water resistance.
