Aaron made a great little kit for anyone who’d like to make their own 9V USB charger that will charge just about any gadget that uses USB, all inside, you guessed it, an Altoids tin. It’s pretty simple to construct one of these, but Aaron put everything together in kit form if you’re not a hardcore Maker yet. For $8.50 it’s a good deal, and it’s always good to support a Maker who’s turning their ideas in to little businesses. Link.
