This Anti Corrosion Free Liquid Level Sensor Circuit show how to make sensor for checking water level in tank or container. It send small electric signal and uses some metal pins to know if water touches them or not. No strong chemical is used in this circuit so metal do not get rust or damage. […]
Capacitive Proximity Sensor Circuit
This Capacitive Proximity Sensor Circuit circuit work like human electronic watchdog. It feel when someone comes close by using electric parts. These kind of circuit are used in smart home things, auto light and security system. The circuit sees changes around it and mostly when person come near. Then it does something like blink light […]
Precision Electronic Rat Repellent Circuit
When we plug in Precision Electronic Rat Repellent Circuit device, it makes high loud noise that rat and mouse do not like. Human and animal cannot hear this noise because its too high sound. Good choice if we do not want to use poison. It just makes strong sound wave and rat gets scared and […]
Xenon Tube Stroboscope Circuit
Xenon Tube Stroboscope Circuit show how to make flashing light using special xenon tube stroboscope. It uses only few parts and can plug in normal 220V power socket to make light flash very bright! WARNING: This circuit is used in high voltage and which can be dangerous Better ask help from expert electrician. This circuit […]
35 Watt Bridge Amplifier Circuit using TDA2030 IC
This 35 Watt Bridge Amplifier Circuit using TDA2030 IC show how to make 35 watt amplifier circuit. This circuit is very powerful. It uses one special chip named TDA2030 but is used for different way to make double power output. This make speaker sound more loud. Be careful circuit uses high voltage and it can […]
Cable TV Amplifier Circuit
Cable TV Amplifier Circuit uses small wire to send signal. When signal goes far it become weak. Like small radio, cable TV amplifier make signal strong again. This helps people get better and clear picture. Circuit Working: Parts List: Component Quantity Resistors (All resistors are 1/4 watt) 680Ω 1 820Ω 1 75Ω 1 100Ω 1 […]
