In this article I have explained how to make an LED dimmer circuit for enabling a dimming facility to any mains operated LEDs bulb. Update: [Using Capacitors, it Works] If you think PWM dimming control might not work for commercial LED bulbs, then the best method is to use series capacitors, which might just do […]

Cube Light Circuits
In this post I have explained how to make simple yet fascinating cube light circuits, in which LEDs are connected inside a plastic cube to produce interesting illuminating effects. All the designs presented below are very simple to build and do not involve any complex microcontroller or Arduino coding. Why a Cube Because cube lights […]
Make this Plasma Ball Circuit
In this post I have explained how to build a simple plasma globe or a plasma ball circuit using very oridinary parts such as an automotive ignition coil, a triac, diac, and a few other passive elements. A plasma ball is a decorative display device in which a very high voltage in the order of […]
Simple LED Circuits
In this post I have explained how to build a few interesting LED circuits, and also learn how to connect LEDs correctly in a circuit. LED stands for Light Emitting Diode, which is actually a semiconductor diode which has the property of emitting light, when current is passed through it in the right direction, or […]
LED Star Circuit
This circuit can be used like a tree ornament, however the LED star circuit explained here has a variation; it’s completely electronic and it provides the impression of an exploding and imploding 6 arm star. A block diagram of the circuit can be seen in the Fig. 1 below, configured using 3 components: oscillator, counter, […]
RGB Light Strip Controller Circuits
In this post we are going to see how we can construct an RGB LED light strip controller circuit for PC cabinets and also for general decoration purposes. In this post we will construct a couple of RGB light strip controller designs, one for a PC cabinets and one for general purpose which can be […]
