Gadget Freaks, We Have a Problem!
"Enthusiasts Joe and Brad designed a clever, electronically controlled, two-stage model rocket powered by a 9V NiCad battery. The heart of the electronic control system consists of a small FPGA with a soft-core processor that runs the control algorithm and logic. It uses a PWM signal from an accelerometer to determine the rocket's acceleration to trigger the ignition of the rocket motor in the second stage, separation of the booster from the sustainer, and the deployment of a parachute that allows the rocket to float gently back to earth."

Gary Knew the Dangers of Eating Uncooked Meat
"So now he's grilling up a storm in his backyard, thanks to the table-top sized Tesla Coil he built and refined to extract long, repeatable sparks. And a lot more goes into this design than plastic pipe and copper wire and tubing. After much optimization, Gary has been able to routinely achieve 9-inch streamers, frequent 11-inch streamers, and even the occasional 14-inch strike to a grounded target (plywood covered with chicken wire)."
