Vehicle tracking system based on GPS and GSM
Presented here is an Arduino-based system for vehicle tracking using global positioning system (GPS) and global system for mobile communication (GSM) modules. GSM modem with a SIM card used here uses the communication technique of a regular cellphone. The system can be installed or hidden in your vehicle at a suitable location. After installing this circuit, you can easily track your stolen vehicle using a mobile phone.

Light animations using Arduino and MATLAB
Light animations are visually appealing and hence widely used for advertising purposes. In this project, we present a MATLAB-based graphical user interface (GUI) approach to control the glowing pattern of a number of light-emitting diodes (LEDs). Use of GUI is advantageous since the user can control illumination patterns while performing other tasks in the PC.

Signal generator and inverter using NE555 timers
Often we require a squarewave signal generator with adjustable frequency, almost equal high and low output pulses and adjustable amplitudes. Here we present a simple, useful and low-cost signal generator built around NE555 timers. Using external switches, you can control or select frequency ranges as per your requirements. However, use of frequencies below 30kHz is recommended.
Voltage regulator as audio amplifier
LM338 voltage regulator can also be used as an audio amplifier. The output voltage can be controlled by varying the IC’s reference voltage (pin 1), which is reflected as the output signal in the speaker. The IC can handle up to 5amp current.
5-Watt audio amplifier using TA7222
Here is a simple 5-watt mono audio amplifier using IC TA7222 that drives a 4-ohm speaker using a 9V battery or a 9V DC adaptor. You can also make a stereo amplifier by using two identical circuits.
Mini fridge with Peltier modules
It was in the middle of 1821 when J.T. Seebeck discovered that if two dissimilar metals connected at two different points are held at different temperatures, a microvoltage develops. This phenomenon is called Seebeck effect. Some years later, Peltier discovered that if a voltage is applied to a thermocouple, one junction of the thermocouple heats up while the other cools down. Opposite of the Seebeck effect is called the Peltier effect.
Automatic certificate generation using MATLAB
MATLAB is a versatile tool that can automate many tasks. Presented here is a MATLAB code to generate certificates for workshops, conferences, symposiums, etc. Conventionally, educational institutions and companies use specialised tools for report cards and certificates generation on a large scale. This MATLAB code can be extended to generate analysis reports for large data sets as well.

ISRO plans igloos on the moon
Hoping to eliminate the need for International Space Station, researchers in India are discovering innovative ways to create livable spaces on the moon—the Earth’s very own natural satellite. The moon is a wasteland with extreme temperature variations and few resources. The Indian Space Research Organisation (ISRO) researchers plan to build lunar habitats on the moon with an aesthetic very similar to an igloo. These igloos will be constructed using a blend of lunar soil and assorted smart materials that will then be fed into a 3D printer. This is an innovative approach to building structures in space, as it eliminates the need for materials to be boosted out of Earth’s gravitational field with costly rockets.

Virtual Assistants For Your Home
Exercising regularly to stay fit is the topmost New Year’s resolution for many. However, every year, most of us fail miserably at following it. This year, however, has been quite different for me. Siri, my personal assistant (courtesy iPhone), seems to have made its personal goal that I achieve my fitness target. It does everything for me—wake me up early, play the right music for me while guiding me with my workout schedule and then keep a calorie count for everything that I eat. Life with Siri is bliss!
