MODEL_ROCKET_IGNITION_CIRCUIT

This circuit requires a 12-Vdc source. A battery pack of eight AA cells in series will work. Meter M1 gives you an indication of battery voltage; change the batteries when you see a noticeable drop in current. The circuit contains two LEDs: LED1 reminds you that the circuit is powered up, and LED2 lets you know that you have continuity through the igniter and are ready to fly. Capacitor C1 gives igniters that extra kick they occasionally need. Pushing the momentary push-button switch (S2) sends the rocket on its way. Use a red switch for that. The igniter leads are connected to the plugs marked igniter.
