While a new product from SparkFun Electronics is ostensibly designed for wiring wearable LIlyPad projects together, this conductive thread could be an instant hit with hackers, too. Garnering around 82 ohms worth of resistance, each 117/17 2-ply spool of thread could help with those delicate ASUS Eee PC hacks. At $16.95 per spool, this conductive thread is not for the squeamish. When inserted in a sewing machine and combined with paper PCBs, however, this thread could open up a whole new concept in circuit design—stitch-a-circuit. —Dave Prochnow
