Fun project from “Gadget Freak” -

William Grill created a gadget that helps control the firing of model rockets. The device provides basic rocket igniter functions, including an igniter “fuse” monitor, audio input and an LED display. The gadget also features a “DeadMan” button (which helps avoid an unintended launch) and a “Fire” 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.
