A series of interactive Chrome Experiments made by Google

Weblab is announced at Google I/O Con which is one among many other amazing products, such as Android Jelly Bean and who can forget the Live Sky Diver’s hangout with the Google Glass.

Google Chrome launched the Web Lab at the London Science Museum, a year-long installation of five interactive experiments designed to tie the Internet’s otherworldly conceptual presence to something physical. Users can access the experiments while physically at the Science Museum or, and this is key to the installation’s concept, from wherever they are in the world via the Internet.

The experiments include a Universal Orchestra, Data Tracer, Lab Tag explorer, Sketch-bots, Teleporter.

The Sketch Bot experiment awesome’ness is that it right opens in your favorite browser (ofcourse all experiments do, Thanks to latest tech HTML5) it captures the image using webcam of your machine and applies a series of Basic Powerful Image Processing Algorithms.

The very first thing is it detects eye’s and subsequently Read More »


Ever thought of how education will be in Top Universities of the planet, but now you can also experience them. Yes, the world’s Top Universities are offering Online Education for free to the world.

Thanks to the Internet.

Of course , Online education is not new, MIT’s Open Courseware was established 11 years ago putting all the syllabi, lecture notes, problem sets and solutions, exams, reading lists, and event video lectures from more than 2,000 MIT courses online to be accessed by anyone.

Simply MIT OpenCourseWare (OCW) is a web-based publication of virtually all MIT course content. OCW is open and available to the world and is a permanent MIT activity.

Official Website

Following the same line , Some 6 years ago NPTEL(National Programme on Technology Enhanced Learning) was launched which is Joint venture of seven IIT’s and IISC ,Funded by Ministry of Human Resource Development (MHRD), Government of India.

The main motto is to provide learning materials, digitally taped classroom lectures, supplementary materials and links to state-of-the art research materials in every subject possible.

Youtube Channel

The Limitation of above said programmes are they are simply an publication of recorded Classroom lectures.

  • They Don’t provide any Certificate or Credential.
  • Don’t track or record the performance of the student accessing the content as NO evaluation tests are conducted.

Revolution in Education

Last fall i.e. Oct 2011 , a group of Stanford professors decided to offer a few courses online free of charge and were overwhelmed when hundreds of thousands of students signed up for their courses.

Introduction to Artificial Intelligence

Introduction to Databases

That experiment has spawned the growth of similar endeavors.

Here’s a guide to some of the newest free education sites and what they offer.


Founder :

Sebastian Thrun, Research professor at Stanford, a Google Fellow and Vice President.

Founder and head of Google X, which is home to projects like the Google self-driving car a.k.a Driver less Car and the recently announced Google Glass.

They do not operate under the auspices of a university, although some of their guest-lecturers do teach at other universities. Their course offerings are aimed at practical computer science skills, like how to build an app or search engine.

Udacity style is first solve style, it has lots of embedded quizzes , real time graded programming exercises and weekly Homework’s and Final exam

List of Udacity Courses

CERTIFICATIONStudents receive a certificate of completion at the end of the course signed by the instructor.

Human Controlled Robotic hand Using Gesture Recognition

Robotic Hand v2.0

Made the robotic hand more complex than previous one.

This time individual fingers actuation by five servos for five fingers.

Controlled by Glove with 5 Flex sensors from Sparkfun USA and 3-axis analog accelerometer with Atmega32 programmed by Arduino

Actuated by 7 servos with an ssc-32 from Lynxmotion taking commands through serial transfer from atmega32 (glove)

I feel sorry for having no recorded video in action only some images :p

ATMEGA Serial Programmer’s Circuit (Hardware) January 2010

Today saw the movies Short Circuit and Short Circuit-2

Its feeling ‘Alive’ by watching Johnny 5’s Action, his dialogues, his innocence

Ben Jahrvi character is cool with his really fuzzy Indian English and he speaks some Hindi words too in Short Circuit 2

The main line of Short Circuit is some what used by Shankar’s Robo.

The coolest thing is Most of the arm movements of Johnny 5 were controlled by a “telemetry suit,” a metallic skeleton carried on the puppeteer’s upper torso. Each joint in the suit had a separate sensor, allowing the puppeteer’s arm and hand movements to be transferred directly to the machine like my Robo hand and Robo Hand V2.0 (done long time ago but did n’t post it till nw)

Read That is Short Circuit is being remake with different plot is set to release in 2011

Johnny 5 and Ben’s accent is unforgettable

Hey Lynxmotion is selling Johnny 5 look alike robots with same brand name

Microsoft Kinect is released just this week and it is hacked for us.

jus like the Nintendo WII is ..!! which has been a part many diy projects and robotics

This guy Hector Martin

hacked kinect to capture data to custom platform (with in 3hrs after purchase of kinect from store -he says this in his video) no need of Xbox

this can be  now be used for DIY, robotics, art, science, education and more. For $150 it’s loaded with tons of great sensors and cameras – now it’s unlocked for creativity.

Adafruit industries had posted this challenge to hack kinect

Remeber AMP Suit from AVATAR

Human Controlled Robotic Hand Using Gesture Recognition

Inspired from AVATAR Amp Suit.


Right i had done only hand wrist..

it has 3 DOF wrist roll and pitch, fingers lock and release.

I liked Arduino Software for coding..

tried but could n’t put time and failed to modify the software for atmega 16/32

So took an atmega8 and made my Pavduino (arduino Board)

one more pic

if u want one ..make one for urself..

complete schematics and projects can be found at

one last thing ..pls lemme know if any of u use arduino software for coding atmega 16/32..

keep rocking..!!


i found the way to program atmega32 from Arduino IDE

Software support

SENSOR:  Linear + 10.0 mV/°C scale factor

ADC Resolution 10bit (1024)
reference voltage 5V
=> 5/1024 = 5mV approx
As ADC results are in factor of 5mV and for 1 degree C the output of LM35 is 10mV, So 2 units of ADC = 1 degree

So to get the temperature
temperature = adc_value/2
