This simple to assemble metal detector circuit makes use of the IC 555, a widely available chip. Despite its various uses, this IC 555 chip functions as a miniature clock in this application producing a signal that aids in the detection of metals and magnets. Circuit Working: Parts List: Component Type Value Quantity Resistor (1/4 […]

Two simple mains phase detector circuit using the IC 4001 and IC 4060 are discussed in this article which are designed to detect the presence of mains AC 220V or 120V phase in the atmosphere. It works without any physical contact with the mains and the antenna of the circuit detects the mains in the […]

Think you have a secret agent gadget that can sense nearby cell phones. Mobile Phone Detector circuit acts like a listener for special radio waves phones use to talk to towers. It can even pick up on these signals before the phone rings kind of like catching a secret handshake between the phone and the […]

Assume you have a disco party, but without flashing lights! This sound to light converter circuit acts like a translator between sound and light. It listens to music and turns those sounds into flashing lights, making your room light up along with the beat. It uses clever parts to change the volume or pitch of […]

A powerful metal detector circuit typically features high sensitivity and the ability to detect a wide range of metal types at varying depths. The coil is a crucial component of the metal detector. A large coil can detect objects at greater depths, but smaller coils provide better sensitivity to small objects. Interchangeable coils are ideal […]

This is a basic circuit for a gold detector! It uses magnets and electricity to see if there is a metal nearby, even gold. The circuit makes a special kind of electricity that flows back and forth really fast. This creates a magnetic field around a coil. When any metal gets close, the electricity flow […]
