Rechargeable LED Lantern Circuit Using Dynamo
In this post we study a simple rechargeable LED lantern circuit which features battery charging option from a dynamo as well as from a mains 220V source. The idea was requested by Mr. Chidimonday. Technical Specifications I like what you doing here, i have even put in work some of your circuit and it functioned […]
Simple Scrolling RGB LED Circuit
A simple RGB (Red, Green, Blue) moving or scrolling LED display can be made using a few 4017 ICs. I have explained the procedure in detail. Understanding RGB LED RGB LEDs have become quite popular these days due to its three-in-one color feature, and because these can be driven independently using three distinct supply sources. […]
Transformerless Constant Current LED Driver Circuit
In this post I have explained how just a single IC MBI6001 can be used as a transformerless constant current LED driver circuit for illuminating a chain of many LED in series. The MBI6001 series of ICs are designed to work with mains AC inputs and convert it into a lower voltage DC output which […]
