The circuit identifies and detects the temperature difference between two sensors and activates a relay when the temperature is not identical on these differently positioned sensors. By: Manisha Patel It’ll also enable you to detect a difference in temperature, although the temperature sensing devices can be set are discretely, using a potentiometer. Operational Details To […]

Tuned Infrared (IR) Detector Circuit
The article is a continuation of the earlier post where we tried to find a solution for creating unique infrared IDs for trains in a model locomotive system. Here I have explained the application in detail and learn how it may be possible to successfully implement the idea using tuned IR detector circuits. The idea […]
Make this Insect Wing Signal Detector Circuit
In this article I have explained a VLF receiver circuit used for detecting insect wing beat signals, the idea was investigated and built by Mr. Steven Chiverton. Insect Wing Triggered ELF An incredibly fascinating electrical outcome successfully identified with the VLF are wing sounds triggered when bugs like bees, flies, and mosquitoes fly within a […]
Thunder Lightning Detector Circuit – LED Blinking in Response to Thunder
This simple circuit will enable you to visualize distant thunder lightning through a correspondingly choreographed LED flashes, exactly in accordance with the lightning that may be taking place somewhere in the distant sky, the response will be simultaneous and thus much prior to the sound that may reach your ears after a few seconds. RF […]
Wheel Rotation Detector Circuit
In this post I have explained a simple wheel rotation identifier or detector circuit which can be used for ensuring a continuous rotating movement of a concerned wheel through an LED, photodiode arrangement. The circuit was requested by nzb109. Technical Specifications I want to generate a trigger circuit to detect that a WHEEL is stationary. […]
Lamp Outage Detector Circuit for Car Turn Signal
The O.E.M. turn signal flashing units installed in automobiles have two basic functions i.e. Flasher and Lamp outage detection. These flashers are usually built with an 8-pin IC like U2044B, U6432B etc. which are specifically made for automotive flashers. Designed and Written By Abu-Hafss Circuit Operation NORMAL OPERATION: -input = Square wave between 11.89V – […]
