An infrared flood light is a circuit that creates an illumination over a wide range of area using infrared frequency. This infrared illuminated area can be perfectly visualized through specialized infrared gasses and IR cameras, but can be totally invisible to naked eye. In this post we study a simple infra red based flood light […]

One Transistor Automatic Battery Charger Circuit
This one transistor cheap battery charger circuit is designed to automatically switch OFF the supply to the battery as soon as the battery has reached its full charge level. A very simple single transistor automatic battery charger circuit is I have I have explained in this article, which uses just a single transistor for the […]
LED Strobe Light Circuit with Chasing, Flashing Effects
The proposed LED strobe light circuit will not only flash a group of LEDs with strobe pulses, but will also create a sequentially chasing effect over the strobing LEDs. You might be quite familiar with colorful LED strobe lights, and should have seen them pretty commonly in parties and discotheques. Let’s see how we can […]
Self Regulating Battery Charger Circuit
In this post I have explained how a neat little self regulating automatic battery charger circuit can be made using just two inexpensive transistors. This circuit will automatically regulate the charging supply to the battery depending on its charge level, by switching the input supply ON and OFF periodically. How it Works As can be […]
Lead Acid Battery Charger Circuits
The lead acid battery charger circuits I have explained in this article can be used for charging all types of lead acid batteries at a specified rate. This article explains a few lead acid battery charger circuits with automatic over charge, and low discharge cut off. All these designs are thoroughly tested and can be […]
20 Watt Fluorescent Tube Light Circuit with 12V Battery Operation
This simple 20 watt home tube light circuit will work with any 12V battery and uses very few components yet is able to produce a reasonable amount of white light. The components used are very common and can be easily procured from the local electronic retailer. The idea is simple, the secondary winding of Tr1 […]
