The world of electronics is changing for the betterment and the new breed of electronic engineers and electronic enthusiasts are now taking over from the traditional engineers. Not only that, kids and teenagers are also improving their skills in electronics by practicing in real life electronic projects and circuits ideas. They are fresh brain that
Mobile Phone Signal Detector – An Electronic Class Project for the Students Here is another circuit from me of a Mobile Phone Signal Jammer (oops) Detector. It can sense the presence of an activated mobile within a distance of three to four meters and lights-up an LED (you can also attach a buzzer instead of LED).
On the specific demands by some of my Facebook page visitors, I have redone this simple Latch Switch Circuit that can ‘hold’ the circuit in either ON or OFF state until any external signal is applied to it. The signal is supplied using ‘Push to On’ Buttons. The concept of a Latch Circuit is that
An ideal school project for small workbench as a School Project. WHAT IS THIS PROJECT It is one of the most commonly used circuits available online. It works immaculately. The circuit is very common; however, I needed this little project on my work bench to immediately test Diodes and Transistors. Testing a transistor using a
In this small and easy project we will transmit music wirelessly using LASER LED. Ever transmitted audio using Li-Fi (Light Fidelity)? Nope. Let’s do it. To transmit music / audio wirelessly we need a transmitter (which is a LASER LED), and a receiver which is a 4V SOLAR Panel (commonly available). Between the transmitter and
Best Battery Charger with Auto Cut-Off
Here is another simple school project that can be used to charge any type of general purpose rechargeable battery or any type of mobile battery without having to worry about overcharging. This battery charger has an auto-cutout feature, which is enabled when the battery is fully charged. Once the battery is fully charged, the output
