When society collapses and the national energy infrastructure goes to pot, at least you’ll still be able to run your fantastical Lego Mindstorms NXT creations. That’s right: the fine folks at Dexter Industries are offering panels, batteries, and all the geegaws necessary to power your projects the old fashioned way: with the sun. The basic dSolar 2W System ($90) features a 9 volt solar panel with enough juice to power the NXt and a single motor in direct sunlight (about 250 mA). There is also a four watt system available for $100, as well as capacitor banks, parallel connectors for multiple panels, and more. Hit up the source link to get started — but not before you check out the video after the break.
