In the figure we show how to use common diodes to get a reference near 3 V in a car gearbox. The transistor must be heat sink mounted. With different number of diodes or even zeners other output voltages can be obtained.
The resistors R1 and R2 consist of 8 220 ohms x 2 W resistors connected in parallel. The...
We found this car theft alarm circuit in a 1988 publication, but the components used can still be...
The frequency of this oscillator depends on the capacitors, being able cover the range between 1...
