This article describes a simple circuit which can be used for pulsing an electromagnet. The IC 555 once again becomes the central part of the circuit. I have explained the making procedure of this simple adjustable electromagnet circuit for varying the magnetic power of an electromagnet. Introduction The circuit was requested by Mr.Jason, one of […]

How to Make a Bridge Rectifier
A bridge rectifier is an electronic network using 4 diodes which is used for converting an AC input to DC output. The process is called full wave rectification. Here I have explained the basic working principle of rectifier diodes such as a 1N4007 or a 1N5408, and also learn how to connect 1N4007 diodes to […]
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. […]
How Thyristors (SCR) Work – Tutorial
Basically an SCR ( Silicon Controlled Rectifier) which is also known by the name Thyristor works quite like a transistor. What SCR Stands for The device gets its name (SCR) due to its multi layered semiconductor internal structure which refers to the “silicon” word in the beginning of its name. The second part of the […]
Car Head Lamp Fader Circuit (Breathing Effect Generator)
The proposed circuit of a modified car head lamp fader, “breather” circuit generates a slow flashing effect over the head lamps every time the lamps are switched OFF. The “breathing effect” continues for a certain predetermined period after which the process automatically shuts off. The circuit was requested by Mr. Ray. Technical Specifications I just wanted to say that […]
LED Tail Ring Light Circuit for your Car
In the following post I have explained a fancy LED sequencing/diverging ring light circuit which can be used as a tail brake light in cars. The idea was requested by one of the avid readers of this blog, Mr. Bobby. I have explained more. Technical Specifications: Hello, I was just reading thru your wonderful article […]
