The Dummy's Guide to Power Supplies
Power supplies -- they're probably the most overlooked components in any PC, until they break. A failed power supply is one of the easiest problems to diagnose, but a failing or inadequate one is much more subtle and difficult to catch. This article is designed to give you a better understanding of what power supplies do, how they work and how to select the right one for different types of computer set-ups.

DC Motor Controlling System
Now a days DC motors plays a vital role in most of the industrial areas, it can be seen in most of the electronic devices. Many methods evolved to control the revolution of a motor. DC motors can be controlled either by software or directly by hardware. Software controlling needs computers which are bulky and common man cannot afford for it, so hardware controls are in use. Even in hardware if it is programmable device then it is preferred because it can be modeled according to the requirements of the user.

Robotic Car using microcontoller 8051
Robotic Car is a miniature prototype car powered by batteries whose various movements can be control either manually or automatically, or the combination of both. Here the command is given through keyboard; it would have been better if we used IR remote control or something of that kind rather than using keyboard for commanding. However, by realizing the complexities we have made simple using keyboard.

Intelligent Train Engines
The idea is whenever any engine observes a red signal on its track it will start decreasing its speed gradually and stops automatically at some distance from the signal pole. After then when it gets green signal the driver can manually start the train and go on. In the mean time when train has not stopped yet and a red signal becomes green then it crosses the signal pole with low speed and then driver can slowly increase the speed.

Dc motor control using IR data communication
Current generation moves into wireless technology. Every one wishes to use remote controls. In this way, the speed of the DC motor is controlled by IR rays. IR rays get modulated with combination of data signal and carrier wave of 38 kHz. At the received end, the modulated signal is demodulated which is given to another controller, connected to the Dc motor driving circuit.

Digital IC Tester using microcontroller
IC tester is used to test Integrated Circuits (ICs). This IC tester is constructed using 8951 microcontroller along with a keyboard and a display unit. Since it is programmable, any number of ICs can be tested within the constraint of the memory available. This IC tester can be used to test a wide variety of ICs which includes simple logic gates and also sequential and combinational ICs like flip-flops, counters, shift registers etc. It is portable and easy to use.

Standards and Specs: RoHS Bureaucracy Runs Amok
The EU has adopted a set of governmental standards for reduction of the use of hazardous materials in electrical and electronic equipment. This standard is called RoHS, and when the ex cathedra RoHS Directive came down, it was missing a little crucial piece of information -- how manufacturers, distributors, and purchasers of parts could communicate to each other the RoHS status of every part.
