In this post I have explained some basic facts about DC to DC buck converters and also learn how to build a simple buck converter circuit. A buck converter is also popularly known as a step-down converter, since its basic function is to step down a higher input voltage level to a lower output voltage […]
Newly Updated Circuit Projects:
75 Watt Power Amplifier Circuit
Our power amplifier only uses a handful of widely available and inexpensive components. Despite this, it can deliver an effective power output of 50 W into an 8 ohm load or 75 W into a 4 ohm load. If distortion is below 0.3% at these maximum power levels, it drops to less than 0.01% from […]
Audio Amplifier Circuit using IC L165
The discussed audio amplifier circuits are designed around the versatile L165V amplifier IC, which is quite adaptable in various scenarios. Working Voltage Range While the minimum recommended supply voltage is 12V, the L165 amplifier circuits show satisfactory operation even below 9V, albeit with somewhat reduced performance. On the upper end, the absolute maximum supply voltage […]
Making a Strong RF Discharge Circuit
In this article we study an RF discharge generation concept also called EMP generator capable of producing an intense RF electrical discharge in the air which may have the potentials of paralyzing and permanently damaging all electronic systems in the close vicinity. The idea was requested by Mr. Nidal. Technical Specifications I have seen a […]
Low Pass Filter Circuit for Subwoofer
In this post I have explained a simple low pass filter circuit which can be used in conjunction with subwoofer amplifiers for acquiring extreme cuts or bass in the frequency range 30 and 200Hz, which is adjustable. How it Works Several low pass filter circuits for subwoofer application are presented all over the net however […]
Footsteps Detector Circuit
By sensing vibrations from footfall, a Footsteps Detector Circuit is a creative and affordable approach for catching intruders. It employs a simple setup with a low-cost loudspeaker and a mute switch to pick up even the smallest steps. This simple circuit is excellent for enhancing building and garden security. We’ll go through the fundamental components […]
