ABSTRACT:
A model rocket launch controller system which can operate in an automatic or manual mode. Selection between the two modes is determined by a double pole double throw switch. When the controller is placed in the auto mode, power is supplied to an electrical timer which counts down from a user selected time until the zero or ignition time. At such time the power is directed to an igniter circuit. An LCD display shows the remaining until ignition. A flasher circuit is provided to drive an LED to indicate the auto mode has been selected. In the manual mode, power is supplied directly to the igniter circuit when a single pole/push button switch is activated. An LED is also provided to indicate mode has been selected.
