LED Driver Power Supply Circuit Using Dimmer Switch
In this post I have explained an effective and efficient high current compact LED Driver power supply using a dimmer switch gadget. In one of my other posts I discussed a high voltage transformerless power supply circuit that used a triac for controlling the capacitive output, however since the concept involved shorting the capacitive output […]
Automatic LED Candle Light Circuit
The post describes a simple 220V mains transformerless LED candle light circuit which switches ON automatically in the absence of ambient light in the room and vice versa. The idea was requested by Mr. Don Technical Specifications I only dabble with electronics here and there but in trying to move from incandescent and CFL’s to […]
How to make simple a LI-FI (Light Fidelity) Circuit
LI-FI is buzzing around the Internet since past few years; recently LI-FI is gained more popularity around the internet and developers. LI-FI stands for Light Fidelity which was coined by Harald Hass. Circuit Objective The objective of LI-FI is transfer data through visible light. Since the bandwidth of visible light is 10,000 times more than […]
220V Dual Alternate Lamp Flasher Circuit
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. Circuit Operation The below shown design depicts a simple mains operated dual or alternate lamp flasher, which is designed to flash or blink two mains operated […]
Christmas LED Candle Light Timer Circuit
In this post I have explained 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. […]
