This circuit generates short pulses. The transistor can be a 2N2222 or BC548 and the frequency is given by the resistors and the capacitor that can be changed.
This circuit has an oscillator triggered when the microphone picks up sounds, noises or even...
Here we show a simple way to use the 4088 or 4018 as a latched switch. The output can drive...
