Here I have explained a an emergency lamp circuit which includes an infrared remote operated brightness control feature. The idea was requested by Mr. Heeran Technical Specifications Can you please help me with two circuits. I want to build a backup led emergency lamp that works via an infrared remote . I want it to […]

Infrared (IR) LED Flood Light Circuit
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 […]
How Contactless Infrared Thermometers Work – How to Make One
In this post I have explained the basic working concept of thermal scanners or contactless IR thermometers, and also learn how to make a practical DIY prototype of the unit without Arduino. In the post COVID-19 era, witnessing doctors holding a contactless temperature gun and pointing toward the forehead of a COVID-19 suspect is a […]
TSOP1738 Infrared Sensor IC Datasheet, Pinout, Working
Video showing the Testing of TSOP1738 with 38 kHz Frequency The TSOP17XX series of ICs are infrared sensor devices designed for sensing infrared frequencies only with a specific range of modulated frequency, and interpreting them into a proportionate magnitude of electrical pulses at the output. This is specifically done to make the sensor immune to […]
Model Locomotive Infrared Controller Circuit
In this article I have explained a model locomotive controller circuit using uniquely set IR beams for different locomotives allowing unique identification signals and controls for the engines. The idea was requested by Mr. Henrik. Technical Specifications Thank you very much for all your circuits / schematics. I will for sure build many of them.For […]
Infrared Car Door Lock Security Circuit
In this post I have explained how to build a simple yet foolproof infrared based remote control, which can be used for locking and unlocking any vehicle door through a personal remote handset. The remote controlled vehicle door lock is foolproof since it works only with a specific IR frequency range, and will not respond […]
