Under $20 MAKE Electronics Gift Guide Good For Frugal Holiday SeasonTimes may be hard economically, but you don't need to give your electronics-DIY enthusiast friend a naff present, thanks to MAKE's sub-$20 Electronics Gift Guide. In fact, some of the items listed are so neat I'm tempted to gift a couple to myself right now... There's a DIY battery-powered USB charger kit good for iPhones, a tiny persistence-of-vision LED display, solar-powered theremin and more. My personal fave is the Drawdio music-making pencil. There're a few LED decoration projects there too: I think my Christmas tree may end up glittering with some DIY LED goodness this year. [Makezine]
