Arduino Modified Sine Wave Inverter Circuit
In this post I will show how to construct a modified sine wave inverter using Arduino. We will explore the methodology of the proposed sine wave inverter and finally, we will take a look at simulated output of this inverter. By Difference Between Squarewave and Modified Squarewave Inverter Inverters saved us from short term power […]
3 Phase Induction Motor Speed Controller Circuit
In this post I have explained the making of a simple 3 phase induction motor speed controller circuit, which can be also applied for a single phase induction motor or literally for any type of AC motor. When it comes to controlling the speed of induction motors, normally matrix converters are employed, involving many complex […]
Temperature Controlled DC Fan Circuits
Have you ever turned up your amplifier all the way, either at a party or just for fun? You may have noticed that “it gets hot” and thought that a fan would be useful. However, at low listening levels, you can hear the fan running. With this circuit, the fan will be automatically controlled by […]
SCR Shunt Circuit for Protecting LED Drivers
The post presents an effective method for protecting capacitive LED driver circuits through an SCR shunt regulator circuit and explains how it can prevent filter capacitors from blowing of and LEDs from getting destroyed. The remedy was requested by Mr. Max Payne. Protecting High Watt LEDs Please suggest regarding 3W, 5W LED bulb circuit design fault. […]
RC Helicopter Remote Control Circuit
In this post I have explained a simple RC helicopter remote control circuit using 433kHz RF modules, without any microcontroller or complex joystick implementations. The idea was requested by Mr. Jitendra. Circuit Objectives and Requirements I am making a large scale RC helicopter. In which I am using 4 motors. For 1st main 12v motor: […]
