Simple Infrared Wireless Headphone Circuit
Anyone can make personal wireless headphones by designing this circuit! In order to transfer the sound it uses infrared or invisible light signals rather than a cable. This enables users to move freely while listening and even control them remotely and also by adjusting the volume or switching tunes. What is a Infrared Headphones Receiver […]
Simple Stabilized Adjustable Power Supply 0-15V/5A Circuit
The construction of a unique power supply circuit that can give the output range of power voltages from 0 to 15V is explained in this article. Also it can power a lot of electrical devices because it has the 5 amp current capacity. Further because this power supply remains stable the voltage will not change […]
Simple Anti Corrosion Free Liquid Level Sensor Circuit
This circuit teaches how to construct a sensor that measures the level of liquid in a tank or other container. By delivering a small electrical signal it uses specific probes to detect whether liquid has touched them. This circuit design uses no harsh chemicals which helps avoid corrosion. Circuit Working: Parts List: Component Quantity Resistors […]
Capacitive Proximity Sensor Circuit
This sensor circuit functions similarly to a human electronic watchdog. It senses if someone is close by using electrical components. These circuits are often found in smart home appliances, automatic lighting and security systems. The circuit detects changes in its environment particularly those brought on by a person nearby. Based on this it then takes […]
Precision Electronic Rat Repellent Circuit
This device plugs in and produces high pitched noises that mice and rats dislike. The noises are too loud for humans and animals to hear. This is a great option if one is unable or unwilling to use poison. It simply shouts with sound waves causing rats to run away. What is an Electronic Rat […]
