Going beyond the expected uses for electronics is great fun...whether or not it develops into something really useful. For those who, like me, need a "kick-start" in hacking devices, I recommend Make Magazine (www.makezine.com), from tech publisher O'Reilly, and Circuit Cellar (www.circuitcellar.com), which has some terrific projects, from solar panels to robots. I would also recommend the upcoming Trenton Computer Festival (www.tcf-nj.org), which features a robotics competition and a circuit-bending workshop.
