A Vibrating Deaf Dog Caller Collar <5$

Step 9 Motor Section

Everyone wants a smooth running quiet motor. Everyone but us, here. Remember the gear we kept from the gearbox? Clip, cut or grind most of one half away, remember to keep the whole hole.

My motor had this cool black ring to plug 2 holes in the end of the motor and support it centered within the shell. I noticed during testing that the ring kicked and bounced the motor to jump and bang about more.

Glue the modified gear onto the shaft with strong glue like epoxy.

After making sure the motor will fit loosely into a motor housing. Drill a hole in the bottom of the housing for the wires. Having switched to digital camera long ago, I used a snap-lid canister empty of a diabetic's blood test strips. Many photography stores have the plastic film cans for free.

I used heat shrink on the wires but it is not really necessary in hindsight.
