Nanotechnology is defined as fabrication of devices with atomic or molecular scale precision. Devices with minimum feature sizes less than 100 nanometers (nm) are considered to be products of nanotechnology. Fabrication of nanomachines, nanoelectronics and other nanodevices will undoubtedly solve an enormous amount of the problems faced by mankind today. Nanotechnology is currently in a [...]

Designing of Amplifier 2x30W with STK465
A amplifier of acoustic frequencies can be manufactured with discernible materials, despite is known so much the difficulties of finding of materials, what the problem of regulations. These difficulties are overcome relatively easily if we find amplifier in form completed. Completed STK465 is an amplifier of acoustic frequencies that offers qualitative output, using minimal exterior [...]
Designing of Electronics Attenuator
Circuit Diagram: Two low voltage, low power zeners are used to control electronically the level of an audio signal. The attenuation range is from 6 to 58dB for an input current from 0.042 to 77 mA corresponding to a control voltage from 2.7 to 7.5V. If control voltage is limited to 5V, the attenuation is [...]

Newly Discovered Species of Spider
A giant spider has been discovered in the dunes of the Sands Of Samar in the Southern Arava region in Israel by the tem of biologist in the University of Haifa- Oranim. The scientific name of this creature is Cerbalus aravensis. The spider found is an nocturnal animal. Its foot is nearly two foot long. [...]
Breathe like fish
After human beings have started swimming, they have been trying various techniques to breathe like fish. Till now they do this by taking the lightweight oxygen cylinders with them but that has the limitation. The oxygen cylinders can be used for the limited time period only. Then, Alan Izhar-Bodner, an Israeli inventor, has developed a [...]
Chicken Implants Would Warn of Avian Flu Fever
Digital Angel manufactured microchips using bio thermal RFID chips in chickens which would serve as the warning system for avian flu. It is made for implantation in the animals. Recently they introduced their BIO-Thermo which is a temperature sensing implantable RFID microchip and identity system. The ultimate goal of the researchers is to make poultry [...]
Basic Electronic Knowldge
All matter, whether solid, liquid, or gas are a collection of molecules, and each molecule is made up of atoms. Each atom consists of a nucleus, which is made up of protons and neutrons, and electrons which circle around the nucleus. Electricity flows when these electrons freely move outwards from their orbits. Some materials becomes [...]
