Sound Activated LED Lamp Circuit
A highly sensitive sound activated LED lamp circuit can be built using just a few transistors and resistors. The circuit is actually a high gain MIC amplifier circuit which amplifies the external sound hitting the MIC. The amplified signal is then used to momentarily illuminate a bunch of LEDs. What does the Circuit do? Basically, […]

Diwali, Christmas 220V Lamp Chaser Circuit
In this post I have explained a simple, compact, 220V, 120V transformerless light chaser circuit which can be used for illuminating 220 V mains operated lamps or bulbs in a sequential chasing manner. Main Technical Features The chasing or running lamp effect can be altered by means of pot controls. The system can be used […]
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 […]
220 V Slow Fade Bedside Lamp Circuit
The operating principle of this children’s night light is to gradually familiarize the child with darkness by gradually reducing the brightness of their bedside lamp. The room’s brightness will slowly fade away and completely extinguish after a duration ranging approximately between twenty minutes and 5 to 7 hours. This duration can be adjusted from week […]
