This is a home made 12 volt DC power pack for your 12 volt gizmos to be more portable.
This one is for AAA batteries, but you could use bigger pipe for AA, C, or D batteries.
1/2" cpvc is smaller than 1/2" pvc, so it's the perfect size for AAAs.
I cut a piece 14 and 1/4" long.
Drill a small hole in an end cap and put a screw in it.
This is the positive contact and is glued right on the end of your cpvc.
Drill a hole in the other end cap, but this time the screw goes in from the outside.
This is the negative contact and the screw will adjust to close the circuit and keep tension on the batteries.
This is also the end that you can remove to replace the batteries, so it needed a tiny screw to hold the cap in place.
When it's finished it looks like this.
8 AAAs is 12 volts and equals about 1 amp hour of power.
Just clip the leads to the screws and you're good to go!!!
