How to use ADC and Microcontroller for Voice Recording

Create a voice recorder using a PIC or a microcontroller and ADC. Use some conditioning circuits to condition the microphone output and feed it to the ADC. The converted values can be stored in some kind of memory. Samsung has some nice memory chips that can be easily interfaced.

PIC Based Automatic Solar Radiation Tracker for Maximum Solar Energy

The following document details the research and evelopment of an Automatic Solar radiation tracker. Fossil fuels are a relatively short-term energy source; consequently, the uses of alternative sources such as solar energy are becoming more wide spread. To make solar energy more viable, the efficiency of solar array systems must be maximized.

Optimal Energy Management System of Plug-in Hybrid Electric Vehicle

Plug-in Hybrid Electric Vehicles (PHEV) are new generation Hybrid Electric Vehicles (HEV) with larger battery capacity compared to Hybrid Electric Vehicles. They can store electrical energy from a domestic power supply and can drive the vehicle alone inElectric Vehicle (EV) mode. According to the U.S. Department of Transportation 80 % of the American driving public on average drives under 50 miles per day.

Road Accident Reconstruction and Simulation

Road accident reconstruction and simulation investigates the accident causes, suggests improvements in vehicle design and investigates failures in vehicle control and safety systems such as the anti-lock brake system (ABS) and air-bag deployment. This project focuses on analysis of crash data from vehicles not equipped with collision warning systems. 

Development & Implementation of Direct Torque Control Scheme for Three Phase Induction Motor Drives using MATLAB

Induction Motors (IM) has always been preferred for its reliability, ruggedness and easier in maintenance. The IM drives controlled with the vector control method has found wide acceptance in the industry.  However, this control technique requires complex coordinate transformation, inner current control loop and accurate system parameters.

Electronic Notepad

The goal of our project was to design and build a portable electronic notepad.  The notepad would have a touchscreen for writing on and memory to store your drawings and notes in.  At your convenience
you should be able to transfer the data to a computer where a software program can read it and then
display it on the screen for you to see.  The notepad should have a fast sampling rate and high accuracy
so your images will appear as you drew them.

MotorCycle Computer Board with Nokia 6280 Lcd

In this project you will see how to use Nokia 6280 Lcd, connected with microcontroller PIC18F4550. MotorCycle Computer Board is implemented on Yamaha TDM850. This projects shows the current gear position (1-5) and neutral position on Nokia 6280 LCD. Please read more....

Thermometer using Nokia 3310 LCD

One useable part of a mobile phone is its LCD, which can be used in many applications where we need data visually presented. Nokia 3310 has a LCD with 84*48 dots, that isn’t that hard to get and can be very useful in DIY (do it yourself) electronics. 

Make Your Own PIC12F683 Microcontroller Development Board

This is a simple PIC12F683 Microcontroller Development Board designed by Rajendra Bhatt. This is a very low cost development board which you can redesign and use it to program your PIC12F683 microcontroller. Thanks to Chris of Pyroelectro.com for posting this project in his website.

Superconductivity and Levitating Bullet Trains

Do you know how the bullet train was possible. One firend of our facebook asked us about the bllet train. Thus, we have posted this article which describes the superconductivity theory. Acc. to Wikipedia superconductivity is "Superconductivity is a phenomenon of exactly zero electrical resistance occurring in certain materials below a characteristic temperature. It was discovered by Heike Kamerlingh Onnes on April 8, 1911 in Leiden. Like ferromagnetism and atomic spectral lines, superconductivity is a quantum mechanical phenomenon. It is characterized by the Meissner effect, the complete ejection of magnetic field lines from the interior of the superconductor as it transitions into the superconducting state. The occurrence of the Meissner effect indicates that superconductivity cannot be understood simply as the idealization of perfect conductivity in classical physics.".

Mobile incoming call indicator

This circuit can be used to escape from the nuissance of obile phone rings when you are at home.This circuit will give a visual indication if placed near a mobile phone even if the ringer is deactivated.
