We can use the 555 timer to hold the cost down of adding a triggered sweep to an economy oscilloscope. The timer is triggered by the circuit’s input op amp, adjusting its flip-flop and cutting off its discharge transistor so that capacitor C can charge. The flip-flop resets and the transistor conducts when capacitor voltage reaches the timer’s control voltage […]

Pulses are received by the timer from the distributor points. When the timer output is high, Meter M receives a calibrated current through R6. The meter don’t receives any current for that part of the duty cycle after time-out. A visible indication of engine speed is provided by integration of the variable duty cycle by the meter movement. Here’s the […]
