In this post I have presented below is also another LED chaser circuit but includes a blinking effect to the design. The circuit was requested by Mr.Joe, one of the keen followers of this blog. The circuit initially was intended to be used for generating LED strobe light effects and was asked to be modified […]

100 to 200 LED Reverse Forward Chaser Circuit for Diwali, Christmas Decorations
In this post I will discuss how to build a simple LED chaser circuit with a push pull or reverse forward sequencing effect. Also, in the later part of the article I have explained how this simple LED chaser could be upgraded to a 100 to 200 LED laser circuit with a reverse forward LED […]
18 LED Light Chaser Circuit Using Two Cascaded IC 4017 and IC 555
In this post I will explain you how to build an 18 LED chaser circuit through a simple cascading of two 4017 ICs, and some passive electronic components. Working Explanation Here we are discussing how to make a simple LED running light which can be built by any newcomer in the field albeit the individual […]
Simple LED Chaser Circuit using IC 555 and IC 4017
Though the more complex lighting might need the incorporation of microcontroller ICs, simpler yet very interesting light effects can be generated through ordinary ICs like IC 4017 and IC 555 as shown below. This is our first LED chaser design which requires very few components for the configuration. (The 100K pot can be adjusted to […]
SMPS LED Bulb Circuit with Dimmer Control using IC IRS2530D
Today we are going to look into a very high efficiency resonant-mode off-line LED driver circuit. It is based on a very popular Infineon article which uses the IRS2530D DIM8 controller IC. Normally electronic ballast technology is used for old fluorescent tube lights, but here Infineon used the same concept to drive high power LEDs […]
