Parametric Power Adapter via Battery Contacts by creuzerm Mar 8, 2013


I have a cell phone with a bad USB charging jack. It's easier to drop in a powered battery blank than it is to fix the jack. I also have cameras that won't record while 'charging' so this will allow me to record and have them plugged in.

This is designed to use a Buck Converter to set the voltage at the 3.6v that most electronics uses now days.

This design is to use 2 nails as the contacts on the battery. Shove the nails into the printed battery housing and solder on the wires from the buck converter.

There are holes provided to run the wires through any edge if needed.

It is currently marked as a work in progress as I need to add the ability to add the 'keys' for batteries that aren't perfectly square.
