“WELCOME” Chasing LED Display
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 […]
IC 555 Timer for Switching Two Alternate Loads with Predetermined Delay
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. Switching Two Loads Alternately I am a regular […]
Fish Aquarium Oxygen Generator
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 […]
8 Function Christmas Light – Automatic Changing Lights
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 […]
220V Dual Alternate Lamp Flasher
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 […]
Arduino Random RGB Light Generator
The article discusses a simple,Arduino red, green, blue LED light effect generator circuit in a random pattern. In one of the earlier posts we came across a similar RGB LED effect generator circuit using Arduino which was programmed to produce the effect in a flowing sequential manner, whereas here the set up can be expected […]
Arduino RGB Flowing Sequential Light
This Arduino RGB sequential light generator circuit will generate a smooth flowing red, green blue pattern over the connected RGB LED. The LED used here is a four pin 30mA RGB LED, common anode type, meaning the common pin for this LED will need to be assigned a continuous positive for the required operations. The […]
Remote Controlled Fish Feeder
In this article we learn how to make a simple infrared controlled fish feeder circuit. The idea was requested by Mr. Harishvar. Technical Specifications I just want a circuit which should turn on when i press and hold a key from my remote. my use is: i have a motor as a vibrator and i […]
Fading LED Light Timer for Fish Aquariums
The post details a simple fading LED light effect generator circuit which can be set for operating in fish aquariums in the prescribed manner for a predetermined length of time. The idea was requested by Mr. Jaco. Technical Specifications My name is Jaco and I am from sunny South Africa. I have an aquarium that […]
Subwoofer Music Level Indicator
The post discusses a LED music power level indicator for indicating a subwoofer bass power range, which can be also modified as an effective dancing Electroluminescent Wire light show. The idea was requested by Mr. David. Technical Specifications Here’s an idea or suggestion for your projects or what ever lol My son picked up some […]
Digital Christmas Candle Light
The post discuses a sequentially advancing 25 LED timer circuit which may be initiated on the 1st day of December so that each LeD lights up on each day until the 25th of December (on Christmas) when all the 25 LeD can be seen lit up. The circuit was requested by Mr. Guy Mathews Technical […]
Simple RGB LED Controller
In this post we learn how to make a simple RGB (Red, Green, Blue) LED controller circuit which may be designated to flash a group of RGB LEDs with a particular sequencing pattern. The idea was requested by Mr. Navdeep. Technical Specifications i want to make a display board with red, green and blue leds. […]
