William Grill created a gadget that helps control the firing of model rockets. The device provides basic rocket igniter functions, including an igniter â€œfuseâ€ monitor, audio input and an LED display. The gadget also features a â€œDeadManâ€ button (which helps avoid an unintended launch) and a â€œFireâ€ button that sends the rocket into the sky. The goal of this inexpensive tool is to reduce the risk of pre-launch ignition and provide a controlled sequence from setup to launch. A small, inexpensive controller manages the DeadMan and Fire buttons.
