farmer friendly solar based electric fence system for rural agriculture with circuit diagram

Electric fences can be used to protect farmhouses, farmlands, forest bunglows, etc from animals. In a way, these simulate the job of a cowboy or forest guard. Already popular in countries where manpower is expensive, electric fences are slowly becoming popular in India as well. These control the animals by giving them a short, sharp but safe shock that teaches them to stay away from the fence. Thus electric fences are economical and practical solutions ....etc

current/voltage regulation or short-circuit protection. These chargers provide raw 6-12V DC for charging the battery pack. Most of the mobile phone battery packs have a rating of 3.6V, 650 mAh. For increasing the life of the battery, slow charging at low current is advisable. Six to ten hours of charging at 150-200mA current is a suitable option. This will prevent heating up of the battery and extend its life. The circuit described here provides around 180mA current at 5.6V and protects the mobile phone from unexpected voltage fluctuations that ....etc

piezoelectric mobile charger circuit mini project pdf

Description: When a piezoceramic trandsucer is stressed mechanically by a force, its electrodes receive a charge that tends to counteract the imposed strain. This charge may be collected, stored and delivered to power electrical circuits or processors.

The Piezo Bending Generator

When the Energy Harvesting Bender is flexed, one layer is compressed while the other is stretched, resulting in power generation. It may be excited by intermittent pulses or continuously from low frequency to res ....etc

Some materials have the ability to produce electricity when subjected to mechanical stress. This is called the piezoelectric effect. This stress can be caused by hitting or twisting the material just enough to deform its crystal lattice without fracturing it. The effect also works in the opposite way, with the material deforming slightly when a small electric current is applied. Piezoelectricity was discovered more than one hundred years ago and has many applications today. It is used in electronic clocks, gas ovens, inkjet printers, and many o ....etc

circuit for mobile phones charged by the power of speech

In the search for alternative energy sources there's one form of energy you don't hear much about, which is ironic because I'm referring to sound energy. Sound energy is the energy produced by sound vibrations as they travel through a specific medium. Speakers use electricity to generate sound waves and now scientists from Korea have used zinc oxide, the main ingredient of calamine lotion, to do the reverse - convert sound waves into electricity. They hope ultimately the technology could ....etc
