Hacks of Electronics
If you want a compact, low-cost home media server that streams movies, TV shows, music, and photos to TVs, phones, and smart home devices, the Raspberry Pi 5 has become one of the best value-for-money platforms available. With its improved CPU performance, faster I/O capabilities, and support for NVMe storage, it stands out as a […]
A Motion Sensor Light is an automatic lighting system that turns ON when it detects movement in its range and switches OFF after a certain period of inactivity. This system is widely used for energy conservation, security, and convenience. The circuit described here uses a PIR (Passive Infrared) sensor, a BC547 transistor, a relay, and […]
The LA3600 Audio Equalizer Circuit is a five-band graphic equalizer, meaning it divides the audio spectrum into five different frequency bands (from low bass to high treble) and allows independent control of each band. This provides a balanced and customizable audio experience. In audio systems, equalization is one of the most essential processes for improving […]
Walking into a science fair, the projects that grab attention are the ones that move, blink, beep, or spark curiosity. Electronics projects do all of that and more. They’re practical, creative, and they give students a chance to show problem-solving skills in action. The best part? You don’t need to be a professional engineer to […]
A clap switch circuit is a popular DIY electronics project that lets you control an electronic device by clapping your hands. The circuit uses the sound of a clap as a trigger to turn the device ON or OFF. It finds wide use in home automation, interactive projects, and temporary lighting solutions. In this article, […]
Dual power supply circuit is the backbone of many electronic systems. Various circuits, especially those involving operational amplifiers, analog devices, and certain digital systems, require both positive and negative voltages to operate properly. This is where Dual Power Supply Circuits come into play. They provide symmetrical voltages (like +12V and -12V, +15V and -15V, etc.) […]
