Brushless motors have much more satisfying results as compared to brushed motors. The basic difference between them is that in a brushless motor, the rotor itself contains the permanent magnets and the electromagnets move to the stator which is quite opposite as seen in a brushed motors. It's more precise and can also factor the speed of the motor into the equation. This makes brushless motors more efficient. There is no sparking and much less electrical noise. There are no brushes to wear out. With the electromagnets on the stator, they are very easy to cool. You can have a lot of electromagnets on the stator for more precise control. The only disadvantage of a brushless motor is its higher initial cost, but you can often recover that cost through the greater efficiency over the life of the motor.

In today’s secure world biometric safety is on the top. Unlike other techniques which make use of passwords and numbers, that are needed to be remembered, biometric techniques make use of human body parts like fingerprints or even iris of your eyes and as we know that these things are unique to all thus it makes biometric systems the most effective over others. In this project I have interfaced a very popular fingerprint scanner R305 with AtMega 16 microcontroller. This module communicates over UART protocol with microcontroller i.e. it makes use of Rx and Tx pin of microcontroller to interact with it.

This tutorial explains how to make your own power supply unit for all your electronics and embedded system experiments. It also has a backup battery which will be used in case of power cuts and a display.
