Everyone has USB gadgets. It’s pretty much a fact of life. Another fact of life is that these USB gadgets also continually run out of power when you most need them. No need to fear, solar power is here! Ditch those crazy wall adaptors, throw out the laptop, and start making your own solar charger!

When I’m building Solar Shrubs and other solar-powered creations, I often scavenge cells from various off-the-shelf devices such as solar garden or security lights. But these cells are rarely labeled as to their voltage, current, and power output. So it’s off to my bread-boarding station. First, I put each cell under a lamp and connect it to my multimeter to get

This instructable is a basic version of Bley Joel’s (“It’s nine o’clock on a Saturday, the regular crowd shuffles in”) Solar Shield, and it should work for most arduinos. I’ve tested it with SparkFun’s Arduino Pro, and the new Leonardo. Myself and the other Solar Pocketeers* are actually waiting for a new set of PCBs
You know theremins, right? Those cool-looking boxes with antennae that produce noise without being touched? They are played by the likes of Jimmy Page of Led Zeppelin, and present in the soundtracks of countless films. Well, with this instructable, I will show you how to build an approximation of a theremin (in principle, at least)

Here’s a six word tragedy: My arduino needs four AA batteries. Really? Isn’t this 2012? Where’s my jetpack?!! Here’s a way to the future — a way to make a solar panel, from scratch, that can power any arduino off of sunlight or even light in your house. Sort of a peel-and-stick power source for
