With this device you can charge any phone that uses a USB connector to charge. This is a great entry level do-it-yourself project for almost anyone – including kids. Start out with a project like this one and you’ll be making your own PV solar panels in no time.
Parts list : Altoid can (or box of similar size), a small solar panel (4V, 75mA), twin AA battery holder (Radio Shack catalog number 270-383), 2 rechargeable AA batteries (1.25V, NIMH), 1 standard diode (IN4148), some wire, USB charger that uses two AA batteries. Most of these supplies you can get from Radio Shack or ebay. The guy who made the YouTube – Kip Kay – also sells a kit on his website. (We do not get anything from the sale of these kits.)
Tool list : Solder, soldering iron, glue gun, glue stick, diagonal cutters, volt meter (optional).
