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 […]

Industrial Valve Switching Detector Indicator Circuit
In this post I have explained a circuit idea which can be used for identifying the switching pattern of set of valves from a remote location, using just two wire from the valve sets to the indicator circuit at the distant location. The idea was requested by Mr. Andreas. Technical Specifications Here is another circuit […]
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 […]
Differential Temperature Detector/Controller Circuit
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 […]
Very Low Frequency (VLF) Detector Circuit
Low frequencies predominantly cover our earth’s atmosphere. This range of frequency may be created by many different sources which may be quite unknown and strange. A VLF sensor equipment can be made to trace these frequencies for investigating the intriguing secrets hidden behind it. Mr. Steven Chiverton investigates. VLF Receiver for Sensing Lightening and other […]
Deep Soil Metal Detector Circuit – Ground Scanner
In this post I have explained a simple deep under soil metal detector circuit for evaluating hidden metals such as gold, iron, tin, brass etc by detecting change in the resistance of the relevant soil layers. Bigger physical objects which might be buried within the topsoil could be unveiled through a modification in the electrical […]
