Wireless Audio Transmitter

A Do-it-yourself Wireless Audio Transmitter to sync multiple audio systems for a wire free world.


In most of our day to day life we come across situation where we need a connect our iPod,mobile,laptop…..etc. to our sound system,but the major limitation is the cable that we need to connect.This probably happens if your sound system doesn’t have a wireless connectivity option.i too had the same problem so i decided yo solve it…:-)Basically its a adjustable FM transmitter that is designed to transmit sound waves to the radio receiver. This way you can easily create a small range FM transmitter of your own and sync multiple sound systems. Add in few more receivers and you’ll get a DIY wireless audio sync device.

We connect the transmitter to our source device and use a old phone or FM receiver to connect to our other sound system.This might seem odd as we are kinda broadcasting our-self but the range of the transmitter is limited to few meters only.The reason choosing this option is that it is very very CHEAP ..!!Also u can connect multiple sound systems at a time without any worries of sync.Hope this project helps you.!

Brain Computer Interface

“A presentation on BCI technology and it’s applications”

This was a college presentation. I and my nerdy friend Chirag Palesha decided to enter this paper presentation competition with something interesting and state-of-the-art. So we opted Brain-Computer-interface. The technology promises to be the future of computer interface. It sounds more or less like the movie where one can read one’s mind, instead this tech. would allow one to exchange thoughts with computers and maybe read some data from computer to our brains. It seems more of a next genertation of superhero power.

Gyro-Controlled Robot

A gyro sensor based control system for robotic vehicles.

This is one of my first robots that i had build using a micro-controller.ADXL 335 based gyro control system designed to eliminate the complexity of button based control. Its a simple system having a gyro-sensor being read by a atmel controller and send to the receiver at the other end.The receiver system then drives a motor controller which in turn drives the motor. I’ve used a simple high-pass filter to reduce the adxl335’s noise.

Omnidirectional Utility vehicle

A D.I.Y. Omni-Directional mobility platfrom.

Its a utility vehicle designed to move in tight space with the advantage of not needing any turning radius. Its simple. Works on omni-directional wheel a.k.a. castor wheels and fun to play with.

Line Follower Project

A simple easy-to-make Do it yourself line following robot. One of the first robots i made.

This is one of my first robots that i had build using a micro-controller. While most of the previous projects i made were mostly mechanical and were either controlled by some manual switch controlled motor or some spring loaded mechanism. Well when in the first year my diploma of Computer engineering at Cusrow Wadia Institute of technology, i was really motivated by few final year degree students back at our hostel, making there final year project. Them called them selves “cybr freaks”, and later on, i happened to joined them. They exposed me to the world of microcontrollers and processors and other cool electronics. It was like having a solution to my every question, building my projects. I digged out a whole lot of material from internet and started learning about the small smart world of electronics.While i was learning computer engineering academically, by night time i ended up learning electronics. This gave me the best of both worlds, the perfect blend of hardware and software.

The very first microcontroller i learned about was Atmels Atmega-16L. Back then when i was new to this it all seem’d state-of-the-art tech. Later on as i explored the world of Atmels i came to know, i was bearly sctraching the surface.

The Line follower i made is build using a atmel atmega16l microcontroller. It was programmed in a pretty basic code. (later i used PID algorithm to control the robot). It used a off-the-shelf IR-Color sensor array. You’ll find a a whole bunch of material on ebay and also some ready to build kits for all Diy’ers.
