The high voltage LM317HV series of ICs will allow to go beyond the traditional voltage limits of an LM317 IC and enable controlling supplies that may be as high as 60V. 0-60V Regulation with a Single IC LM317 Therefore now you can build a universal 0-60V regulated power supply circuit loaded with all the essential […]
Newly Updated Circuit Projects:
Recover Energy from Induction Cooktop
The idea of acquiring free energy from induction cookwares using an external bifilar coil was suggested by one of the keen enthusiasts and a regular visitor of this blog. I have explained more regarding the details of this interesting radiant energy device, as explained by the author himself. WARNING: THIS CONCEPT ATTEMPTS TO VIOLATE THE […]
Making a Thermoelectric Generator (TEG) Circuit
A thermoelectric generator (TEG) is a kind of “radiant energy device” which has the property of converting temperature into electricity. In this post I have explained a little about this concept and find out how we can use it to generate electricity from heat and cold. What’s TEG In one of my earlier articles I […]
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 […]
Arduino IR Remote Control Circuit
In this post I will show how to construct a customizable Arduino based IR (infrared) based wireless remote control switch, which consists of IR remote and a receiver, you may modify according to your needs. In the later part of the article I have explained about an upgraded foolproof version of an IR remote control […]
Natural Mosquito Repellent Using High Watt Resistor
As the name suggests, to build this simple natural mosquito repellent circuit you will just require a high watt resistor, a few drops of lemon eucalyptus oil and mains supply input. Chemical Based Mosquito Repellent are Harmful for Health You might be already familiar with these popular ready made mosquito repellent units which come in […]
