Altoids Rocket Launcher
Evan and I have always been into Estes model rockets. I've always been particularly interested in unique methods of igniting the rocket ignitors. This is a really old launcher I built back in 2000. It's guts are reaaally low level timer/counters and a 555 timer. The countdown begins as soon as the case is opened. It beeps and the red led flashes. Different delays are set by the dip switch.
