While there is no dearth of solar battery chargers that are available on the market, most of them are either too expensive or are made using plastic, which we all know isn’t the most green material around. To make solar battery chargers affordable and customizable, industrial designer Ula Kowal has come up with an open source guide that lets you create your own solar charger at home using recycled materials.
Dubbed IGE, the open source energy generator can be made by using five 20mA solar cells and five AAA rechargeable batteries from old solar garden lamps, a USB socket from an old PC, some old PC wire, a couple of diodes from an old PC and some battery holders again from solar lamps.
The step-by-step guide, which can be downloaded here [PDF], comes with complete instructions and templates that can be printed and cut using a blade to start the process of building a solar battery charger. The main body of the charger is to be made using glued sheets of recycled cardboard. Once the construction of the body is complete, a few minutes of soldering the electronic components along with the solar cells, would help you make your own solar battery charger. The instructions are simple and we believe that the DIY won’t take more than a couple of hours, provided you have the materials lying around in your home.
