Ice Warning Circuit for Automobiles
Devices that react to variations in atmosphere or fluid heat are simple to construct due to the easy availability of thermistors. This car ice warning circuit explains how to implement a thermistor like a transducer in a circuit that continuously blinks a warning lamp as soon as the atmospheric temperature drops to around 0 °C. […]
Ultrasonic Fuel Level Indicator Circuit
An electronic device or circuit which detects and indicates the various fuel levels in a fuel tank without a physical contact, through ultrasonic waves, is called an ultrasonic fuel level sensor In this post I have explained how to build a simple fuel tank level indicator circuit using Arduino and ultrasonic sensors. In every vehicle […]
5 Best 40 Watt Amplifier Circuits Explored
In this post I will talk about 5 outstanding, easy to build, low distortion Hi-Fi 40 watt amplifier circuits that can be further upgraded to higher wattage through some minor tweaks. This article was contributed to me through email by a dedicated follower Although you may find several hybrid output modules available, hardly any of […]
Electronic Touch Organ Circuit
An electronic touch organ is an intriguing musical device which produces very pleasant musical notes in response to finger touches on special touch sensitive electronic pads or buttons. Modern day organs are, however, very costly which usually places these outside the reach of the majority of folks. Low cost options types lack performance, and are […]
Laughter Sound Simulator Circuit
As the name suggests, this device generates electronic sound, resembling human laughter. BASIC DESIGN To enable the circuit start the proposed operations, it must have a fundamental sound input or frequency for processing. This basic frequency is established through a simple oscillator operating at 1 kHz frequency. The next, requirement would be to process this […]
