A Powerful Metal Detector Circuit offers high sensitivity and can detect many types of metals at different depths. However, the most important part of the circuit is the coil. Furthermore, a large coil can detect objects buried deeper underground, while a small coil works better for locating smaller items, therefore, using interchangeable coils provides the […]
Simple Gold Detector Circuit
This project is for Simple Gold Detector Circuit and it uses magnet and electric to find metal and even gold. Here, the electric goes fast back and forth and this make magnetic field in coil; and when metal come close then electric changes. Also, it is an fun project to learn about metal detector but […]
Simple 20 Watt Fluorescent Inverter Circuit
Imagine we have normal car battery and we want to use it for fluorescent light, but the battery voltage is too low and it does not work like this. So we use special and Simple 20 Watt Fluorescent Inverter Circuit like a magic box and this box has transformer, transistor and other parts which change […]
Electronic Drums Simulator Circuit
Do anyone want to play drums but do not have full drum kit? then this Electronic Drums Simulator Circuit can help as it work like small electronic drum. Also, it uses smart parts to make drum sound like kick and snare; sound come from electronics and not from real drum. Furthermore, it can make sound […]
PWM Motor Speed Control Circuit using Two Transistors
In this article, resistors can provide basic speed control, but they cannot adjust motor speed efficiently or smoothly. Therefore, this smart PWM Motor Speed Control Circuit using Two Transistors offers a more effective solution. It works like a dimmer switch for the motor and we can turn a knob like a potentiometer to change how […]
Microphone Preamplifier Circuit using Two Transistors
Imagine our voice is a tiny whisper going into a microphone. This Microphone Preamplifier Circuit using Two Transistors works like a small megaphone; it makes the whisper louder so the main amplifier can clearly boost our voice. Circuit Working: Parts List: Components Values Quantity Resistors (All resistors are 1/4 watt unless specified) 100k 1 120k […]
