Back in college, I minored in physics, and while taking Linear Integrated Circuits, I became interested in using analog circuits for control purposes. Has anyone here attempted to use an analog circuit for rocketry applications? I had an idea for a timer, using a temp dependant resistor, a potentiometer, and a zener diode. The pot and the temp dependant resistor are placed in series, with the pot first. The zener diode is attatched between the pot and resistor, reverse biased. As the resistor heats up, the resistance rises, and the voltage at the node between the three components rises, until the zener voltage is reached, and the zener diode begins passing current, which can then do whatever. Any thoughts?
