Gadget Freak Case #188: Rocket Controller Goes Wireless

June 23, 2011

Here's a wireless way to launch a rocket. Gadget Freak William Grill modified his rocket igniter from an early Gadget Freak submission, Case #124: Controlling the Rocket Fire. The earlier model included an igniter "fuse" monitor and single discrete LED display. William re-tooled with this new gadget. This one has similar function, but now it comes with a wireless feature that eliminates the wired link, thus freeing the user ... to get out of the way. Click here to see William's original gadget.
