This Anti Corrosion Free Liquid Level Sensor Circuit show how to make sensor for checking water level in tank or container, as it send small electric signal and uses some metal pins to know if water touches them or not. Also, this circuit does not use strong chemicals, so it does not rust or damage […]
Capacitive Proximity Sensor Circuit
This Capacitive Proximity Sensor Circuit works like an electronic watchdog that detects when someone comes nearby using electronic components. Also, these kinds of circuits work in smart home devices, automatic lights and security systems; the circuit detects changes around it, especially when a person comes near and then it blinks a light or sounds an […]
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. Also, humans and most animals cannot hear this noise because of its very high frequency, hence, this device is a good choice if we do not want to use poison, as it produces […]
Xenon Tube Stroboscope Circuit
Xenon Tube Stroboscope Circuit show how to make flashing light using special xenon tube stroboscope, as this circuit uses only few parts and can plug in normal 220V power socket to make light flash very bright! WARNING: This circuit uses high voltage, which can be dangerous, so we should seek help from an expert electrician. […]
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, as this circuit is also very powerful. Here, the circuit uses a special chip called TDA2030 in a different configuration to produce double the power output and make the speaker sound louder. Hence, be careful circuit uses high […]
Cable TV Amplifier Circuit
Cable TV Amplifier Circuit uses small wire to send signal, but when signal goes far it become weak; like small radio, cable TV amplifier make signal strong again. Also, this circuit helps people get better and clear picture. Circuit Working: Parts List: Components Quantity Resistors (All resistors are 1/4 watt) 680Ω 1 820Ω 1 75Ω […]
