30W Mini Mosfet Amplifier

This mini mosfet amplifier project was a sort of challenge: designing an audio amplifier capable of delivering a decent output power with a minimum parts count, without sacrificing quality. The Power Amplifier section employs only three transistors and a handful of resistors and capacitors in a shunt feedback configuration but can deliver...

Darlington Pair to Drive DC motor Circuit

A normal variable resistor cannot directly control the speed of a motor since motors draw large amounts of current which would burn out the potentiometer. Instead, the small amount of current that the potentiometer can pass can be amplified into order to run the motor. This amplification can be achieved using Darlington Pair of transistors.Darlington...

Bistable Multivibrator Using IC 555 Circuit

555 Bistable Multivibrator circuit acts as a basic flip-flop. The Output will stable in two states: output high and output low. The switching of the output waveform is achieved by controlling the Trigger and Reset inputs which are held "HIGH" by the two pull-up resistors, R1 and R2. By taking the Trigger input (pin 2) "LOW", switch in Set...

IC 555 Monostable Circuit

Monostable circuit produces one pulse of a set length in response to a trigger input Such as a push button. The output of the circuit stays in the low state Until there is a trigger input, Hence the name "monostable" meaning "one stable state".This type of circuit is ideal for use in a "push to operate" system for a model displayed at EXHIBITIONS....
