Cox Battery Project

Here is a quick little project I threw together. I always loved the aesthetics of the cox 1 1/2 volt "Super Starting Power Battery". Since they're all so old now non of them would have a charge obviously. So I decided to make a little insert that I could place in the battery box so I can still have the old look of the original battery but still have it be useful when I take it to the field.

I started by making a small plastic try insert out of modeling styrene.








Then I got a DC to DC adjustable buck converter and calibrated it for a 1.5v output.




After that it was a simple installation of all the parts. I did add some tungsten weights to the bottom just to give it a bit more heft and stability.





Finally the finished project:







I'm sure this is a common project in the cox community but I just thought I'd share my version.
