Transformerless Power Supply Circuit

http://circuitdigest.com

We can convert the High voltage AC into Low voltage DC without using the Transformer. This is known as Transformerless power supply. The main component of a Transformerless power supply is Voltage dropping capacitor or X-rated capacitor, which are specially designed for AC mains. This X rated capacitor is connected in series of Phase line of AC, to drop the voltage.

Cell Phone Controlled Robot using 8051 Microcontroller

http://circuitdigest.com

In this project we are going to build a cell phone controlled robot using 8051 microcontroller. Cell phone controlled robot runs over mobile DTMF technology. DTMF stands for Dual Tone Multiple Frequency. There are some frequencies that we use to create DTMF tones. In simple words by adding or mixing two or more frequencies we generate DTMF tone.

RFID Based Attendance System Project

http://circuitdigest.com

In this RFID based Attendance System project, we will explain you how can we count attendance automatically by using RFID cards. RFID Tecnology (Radio Frequency Identification and Detection) is commonly used in schools, colleges, office and stations for various purposes to automatically keep a track of people. Here we will count the attendance of an authorised person by using RFID.

The Engineer’s Guide To High-Quality PCB Design

http://electronicdesign.com

Virtually every electronic product is constructed with one or more printed-circuit boards (PCBs). The PCBs hold the ICs and other components and implement the interconnections between them. PCBs are created in abundance for portable electronics, computers, and entertainment equipment. They are also made for test equipment, manufacturing, and spacecraft.
