You know the drill. Every year, the holiday gift-purchasing storm sweeps the nation, and you’ll probably give or receive some new electronic gadget. Shortly thereafter, you’ll have myriad unused gadgets sitting around, sad and probably obsolete. In anticipation of the influx of old and unwanted electronics, a Sacramento business called Cyber Eletronik recently created the Sacramento Tech Exchange. Tech items you donate to the exchange will be updated and given a new life in the hands of the less fortunate. It benefits the Earth, the less fortunate and your karma.
