In this article I have explained a relatively simple triac controlled automatic mains voltage stabilizer circuit, which uses logic ICs and a few triacs for controlling the mains voltage levels. Why Solid State Being solid state in design, the voltage switching transitions are very smooth with minimum wear and tear, resulting in efficient voltage stabilization. […]

PWM Controlled Voltage Stabilizer Circuit
In this post I have explained how to make a high power 100V to 220V H-bridge mains voltage stabilizer circuit using automatic PWM control. The idea was requested by Mr. Sajjad. Circuit Objectives and Requirements Secondary Features I like it to has an LCD to display parameters and a custom name,high voltage cut off, over […]
PIR Controlled Solar Garden Light Circuit
In this post I have explained a simple automatic PIR controlled solar garden light circuit which will switch ON the LEDs only under two conditions: when it is completely dark and when a human being is detected in the vicinity. The above feature of the circuit ensures that the LEDs are turned ON only when […]
3 Laser Beam Controlled Circuits Explored
A compact, battery-powered transmitter emits a LASER beam when the control push button is activated. The beam is frequency-coded to provide a maximum level of reliability in transmission. The receiver can be located at a considerable distance from the transmitter (up to several tens of meters). The light beam, by definition, remains highly focused, and […]
Simple Remote Controlled Curtain Open/Close Circuit Diagram
In this article I will explain a simple curtain controller circuit designed by me which can be used to control the opening and closing of a curtain through a remote control. Overview Referring to the circuit diagram in your screen, we can see there are just two relays employed for implementing a remote controlled opening […]
How to Make a PWM Controlled Fan Regulator Circuit
In this article we look into a simple 220V mains PWM controlled fan or light regulator circuit which does not require a microcontroller or costly triac drivers for the intended operations. Capacitive Phase Chopping All Ordinary types fan regulator and dimmers which rely on capacitive phase chopping technology have one drawback in common, these generate […]
