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 […]
The collection of circuits resented in this category can be exclusively used in parties and get-together for illuminating the area with coruscative lights blinking and sparkling at a desired sequence.
You can easily build these and implement these LED based light effects by following the simple diagrams and assembling the components as described in the relevant articles.
The post explains how to make a chasing “WELCOME” display circuit sign board, which illuminates each alphabet sequentially until all the 7 alphabets are lit and then the whole display shuts off, the cycle continues permanently as long as the circuit is powered. Overview I have already discussed a similar concept explaining a bar graph […]
In this post we learn how to make a simple IC 555 based alternate relay timer circuit for toggling a couple of loads alternately with a specified length of delay, as determined by the calculated values of the relevant components. The idea was requested by Mr. Sanjoy. Circuit Objectives and Requirements I am a regular […]
In this article we discuss how to make a simple fish aquarium oxygen generator circuit using the concept of electrolysis of water. Generating Pure Oxygen The production of oxygen through electrolysis can be expected to supply a pure and a bigger quantity of oxygen compared to the usual pumped air concept which injects only only […]
A simple mains operated, transformerless 8 function Christmas light circuit can be made by using a single IC, a rotary switch and a few SCRs, let’s learn the procedures in detail. The circuit is based on a single chip UTC8156 which is internally preprogrammed to produce 8 unique selectable light effects across 4 numbers of […]
This is a mains operated transformerless flasher circuit that can be used for alternately switching a couple of CFL or similar 220V/120V lamp to produce a decorative lighting effect. Simulation and Working The below shown design depicts a simple mains operated dual or alternate lamp flasher, which is designed to flash or blink two mains […]
