4-AA USB Charger for Cellphones & MP3 Players
Mabuhay! This instructable is a simple, portable and easy to use device. It is portable because I want my stuffs to be "on the go" anytime and anywhere -- especially during long travel and blackouts. It is a charger made for any kind of device or gadget that re-charges using USB charger like Apple iPod and Motorola and other phones. I don't have great knowledge in electronics so I made one without using capacitors, resistors and etc. Hope you like it.
Materials Needed
Check out the photos.
The USB receptacle I used came from our broken CPU.

Create a Housing/casing
I used 1.5mm and 3mm white sintra board. My original concept was to use an empty small ice cream container. I use sintra board to make it simple and look Apple-ish product, LOL. There was no specific plan on the dimensions, I just make sure that the battery holder, switch, USB (female) and all internal parts will fit inside.
