In this post I have explained a simple day, night triggered automatic door lock circuit, which can be used for autonomously unlocking a kennel door during day break, and locking it when night sets in. The idea was requested by an avid reader of this blog, Mr. Norman, as given below. Design Request and Specifications […]

Automatic Night Activated Wireless Light Circuit for Paintings
In this article I have explained a basic wireless LED light circuit that may be used to autonomously turn on LED lights to illuminate artworks at nighttime.
75 Watt Power Amplifier Circuit
Our power amplifier only uses a handful of widely available and inexpensive components. Despite this, it can deliver an effective power output of 50 W into an 8 ohm load or 75 W into a 4 ohm load. If distortion is below 0.3% at these maximum power levels, it drops to less than 0.01% from […]
Analyzing Class B and Class AB Amplifier Models
Both the majority of class B or AB power amplifiers currently encountered in HI-Fi amplifiers are presented in the form of integrated circuits specifically designed for this purpose. It is interesting for technicians to know how this type of amplifier works, if only out of intellectual curiosity. The provided model allows the study of several […]
Train Sound Simulator Circuit
The train sound simulator circuit is an electronic circuit that generates a realistic sound that mimics the sound of a train moving on tracks. The circuit is designed to be integrated into a model train set or layout to add to the overall realism of the scene. The sound is produced using a combination of […]
The Perfect FM Radio Circuit using TDA7000 IC
Here we are going to see how we can build a very simple, yet perfect FM radio circuit using one single IC called TDA7000. This IC already has everything inside it, so we do not need to do too much headache wiring around it. First of all, before we build, we must understand what each […]
