In this article I have explained 10 simple automatic emergency light circuits using high bright LEDs. This circuit can be used during power failures and outdoors where any other source of power might be unavailable. What’s an Emergency Lamp An emergency light is a circuit which automatically switches ON a battery operated lamp as soon […]
Newly Updated Circuit Projects:
Making LED Lamp using Cellphone Charger
A plug-in type powerful wall LED lamp can be built at home by using a few white LEDs and by powering it through a cell phone charger. The power from cell phone charger is around 6 volts at 500 mA approximately. Why use a Cell Phone Charger The supply from a cell phone charger may […]
Make an Electronic Candle at Home Circuit
The proposed electronic candle circuit does not use wax, paraffin or flame, yet the device perfectly simulates a conventional candle. Basically it incorporates ordinary electronic parts like LED and battery. The interesting part of it is that it can be extinguished with literally a puff of air. The proposed electronic LED candle circuit helps you […]
How to Illuminate 100 LEDs from 6 Volt Battery
In this article I have explained an innovative way of driving more than a hundred white LEDs from a 6 volt battery. The circuit utilizes the IC 555 for driving a step up transformer, whose output is finally used for illuminating the LEDs. A special PWM configuration makes the circuit much power efficient. Main Stages […]
Sequential LED Array Light Circuit
In this article I have explained how to make a sequential LED array light circuit with an sequentially illuminating LED forming a bar graph kind of LED formation. Introduction In this article I have explained a simple method of making an incremental LED light using the IC 4017, which is rather equipped with specifications not […]
Transformerless Automatic Night Lamp Circuit
This transformerless solid-state automatic night lamp operates without using bulky transformer, and automatically switches ON some LEDs during night, and switches them OFF during day. In this post I have explained how to make a transformerless automatic darkness activated LED lamp circuit, using a couple of transistors and capacitive based power supply, eliminating the use […]
