My first obstacle avoiding bot based on the tutorial by Community of robots. This is my first one and helped me learn a bit about sensors, feedback and servo operations.

I was fascinated by LASERs when I first went to IIT Kanpur during my school days. Since then I have been reading / playing a lot with LASERs. My first one was a LASER trip wire and then a LASER pattern generator. It all was around 10 years back. Having recently acquired an Arduino UNO a plethora of options have opened up. I have started to learn from the beginning and this time I have the power of a...

Arduino – 7 segment Dice

January 23, 2012

I have been waiting to play with embedded programming since and recently ordered an Arduino. I tested the spare LCD and displays with the normal tutorial commands and went step by step remeber the thing about slow and steady! I want to build a vector LASER projector and a quadrocopter someday but that is too far. It is kind of my VISION. My Mission is to learn embedded programming via arduino. It is one hell of a kit. My very first experiment was a 7 segment dice.

Why investors are not making returns in the stock market

January 4, 2012

In the last 10 years, sensex gas grown at 17.79% CAGR. That means, if someone could have invested Rs. 1 lac 10 years back, it could have grown to 5.14 lacs. In the last 10 years one third of diversified equity mutual funds have delivered a CAGR of more than 25%. That means if someone could have invested 10 years back in these mutual funds Rs.1lac, it could have grown to Rs.9.31 Lacs. But how many investors have REALLY got these kinds of returns…? In this context knowing about the...

Recently I was provoked by a thought of retweeting a tweet by some particular tweeter automatically, and thus begun my search for such a tool or web app. To my surprice I could not find any instead I stumbled upon how to use yahoo pipes to do that.
The way i did it was as follows
Instead of creating my own pipe from scratch I used clean twitter feed pipe and edited it to my convinience.

Firstly You need to have key word.
I took it as Guykawasaki
so for me the feed url would be
http://search.twitter.com/search.atom?q=guykawasaki as I wanted to retweet all posts by Guykawasaki

1. Add a fetch feed box and enter the url in it.

2. Next add a Regex boc to filter our the unwanted content based on regular expressions

3. Then add a filter funtion to perform filtering on basis of the above expressions

4. Connect the pipes and you are done.

Now we goto the properties of the pipe and click run it. Once we are on the results page which looks like this.

Here what is of important to us is the RSS of this pipe. Clicking it gives us the RSS link of the pipe and we are almost done.

Now what we need to do is just use twitterfeed to automatically post the updates to the required twitter account.
If unknown to twitterfeed see how to do it here.
