A calibration method for laser-triangulating 3D cameras (Electronics Project)

A laser-triangulating range camera uses a laser plane to light an object. If the position of the laser relative to the camera as well as certain properties of the camera is known, it is possible to

Digital Code Lock with LCD and Keypad using AT89C2051 (Electronics Project)

In this Project, ‘Digital Code Lock using AT89C2051′ LCD is used for display and a keyboard is used to input the keys. The project source code is written in C. Both the C files and hex files are given for … Read more »

Rotating Electromagnetic Field for Crack Detection in Railway Tracks (ECE/EEE Project)

The main problem about a railway analysis is detection of cracks in the structure. If these deficiencies are not controlled at early stages they might cause huge economical problems affecting the

Simple Automatic Water Level Controller (ECE/EEE Project)

Water-level controllers are common nowadays. The one described here is built around timer NE555 and inverter buffer CMOS IC CD4049. It uses readily-available, low-cost components, and is easy to build and install on the over-head tank (OHT) to prevent wastage … Read more »

Chaos-based Random Number Generator in Finite Precision Environment (ECE/EEE Project)

Yet having a very long history, how to generating good random number sequences still remains as a technical challenge. Although some mechanical ways, such as tossing a coin or rolling a dice, are commonly accepted as good random sources, they … Read more »

Simulation with VHDL and code generation (Electronic Project)

SyncSim is a simulator framework capable of loading different simulator modules. It is used today with a module that simulates hardware models described with Java. This simulator module is used together with a model of a MIPS processor core in … Read more »

Energy Efficient Virtual MIMO Communication for Wireless Sensor Networks

Virtual multiple input multiple output (MIMO) techniques are used for energy efficient communication in wireless sensor networks. We investigate virtual MIMO for fixed and variable rates. We propose energy efficient routing based on virtual MIMO. The simulation results show that virtual … Read more »

Simple Fire Alarm Circuit

Here is a simple fire alarm circuit based on a LDR and lamp pair for sensing the fire.The alarm works by sensing the smoke produced during fire.The circuit produces an audible alarm when the fire breaks out with
