Super Boost charging my phone off of two AA batteries.

I think that is enough update posts for right now.

I designed a 3D printed case for the Super Boost. It has two parts and is designed to hold two cylindrical 18650 lithium cells.

So I just finished building my first Super Boost. It converts 2.2V – 4.5V to a steady 5V source. This is perfect for charging a cell phone or any other device that charges via USB by using 2 AA batteries or a single cell lithium battery.

The project page is here and the DIY page on assembly is here.

Going to solder one together tonight.
