Lamps and Lights

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, […]

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 […]

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 […]

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 […]

In this RGB spotlight mixer circuit project, 3 individual spot lights are used, having red, green and blue focus light bulbs in them. The lights can be focused on walls, ceilings or floors to create interesting slow rising, slow fading red, green blue light patterns that mix and diffuse to generate interesting, additional secondary colors. […]

Nowadays the CFL and fluorescent lamps are almost completely replaced with LED lamps, which are mostly in the form of circular or square shaped flat ceiling mounted LED lamps. These lamps beautifully merge with the flat ceiling surface of our homes, offices or shops providing an aesthetic look for the lights, along with a high […]
