In this post I have explained the construction details of a triac based push-button dimmer circuit which can be used for controlling incandescent, and fluorescent lamp brightness through push-button pressing. Another feature of this dimmer is its memory, which retains the brightness level even during power outages, and provides the same lamp intensity after power […]

Xenon Strobe Light Control Circuit
The circuits presented in the following article could be used for generating strobed lighting effect over 4 Xenon tubes in a sequential manner. The proposed sequential xenon lighting effect could be applied in discotheques, in DJ parties, in cars or vehicles, as warning indicators, or as decorating ornamental lights during festivals. A wide range of […]
Using UV-C Light Chambers for Disinfecting Humans from Coronavirus
A rather easy way of disinfecting humans and objects on a large scale and in public places could be by irradiating them with ultraviolet rays (UV-C), in special UV-C illuminated chambers or passages. This includes the pandemic COVID-19, which can be suppressed by installing and implementing these specially created UV-C germicidal lamps. The following article […]
Touch Dimmable LED Light Bar Circuit
This LED light bar with dimmable feature will allow the user to adjust the brightness of the lamp in 4 steps, with100%, 50%, 10% and 0% illumination control at each subsequent steps. The idea was requested by one of the avid readers of this blog. Here’s the required working concept. The Design The basic design […]
LED Obstruction Light Circuit
Obstruction lights are warning lights that we see at the top of tall structures like towers and skyscrapers, installed for indicating the aircrafts and other flying objects about these obstructions. These lights alert the flying aircrafts regarding the minimum height they should maintain above these tall structures to avoid a possible collision and accidents. Obstruction […]
Musical Christmas Decoration Light Circuit
A very interesting musical Christmas decoration light circuit can be built using a single IC, and some other few passive components, let’s learn the details as furnished below. By: Ritu Panday How it Works The circuit of a selectable muti-musical song player with 5 sequential light pattern generator is discussed here using just a single […]
