So Glad to heard that I have been selected for "Google summer of code 2013" as a Student this year again, yeap for the second time! :-) This year it was very amazing and much more competitive than last year. To mention a lil wow fact: I have been selected for *two* open source organizations this time!! In-fact those are two great organizations:"Raxa" and "OpenMRS" both are related to Healthcare informatics. (Sometimes we need to take some crucial decisions in our life.) So finally I chose OpenMRS as my organization, because of my love towards this awesome open source community which I have been with over year now,
Lastly I wanna thank Lord Budhdha who were always blessed me to get through this big achievement! නමෝ බුද්ධාය.
Congratz everyone! Looking forward for a great summer with OpenMRS!
If you are interested, My Project details can be found here:
I will be developing a "User-driven healthcare" system by integrating OpenMRS-core as the base.

Raspberry PI is an awesome mini Linux Computer. I was totally amazed with the computing power it bears and the inbuilt GPIO pins make it even more awesome! I am pretty sure this cute lil linux box opens unlimited possibilities for a creative tech person because of this Computing and Electronics prototyping features it bears. So thats it a lil intro about RasPi and here we go, my 1st project using it! xD
I have used Raspbian Wheezy Linux distro installed to my Sandisk SDHC 8GB class 10 microSD card. My monitor has no HDMI port, So I had to use home Sony TV for it. Plugged everything, powered on, And booyah!the PI booted successfully!
Small issue was noticed after few mins, its only about colors! the colors were only black and white. So I googled about it and found that some TVs display like this and i need to edit a conf at PI O/S. If you need more info can be found here: (Simply the fix is change to: "sdtvmode=2" at "/boot/config.txt" file, and do a sudo reboot, Voila! colors will come up!)
Despite blinking LEDs xD I have tried a new tutorial to stream video from a Web Cam attached to PI to Web server, So the video stream can be accessed by the LAN network. I have used my router for this connected to PI.
RaspberryPI is awesome for electronics-computer-mobile combinated projects. And while surfing I found theirs another product called beagle board similar to RaspberyPI. : http://beagleboard.org/
Since the highly marketing strategies of RasPI we dont aware much about this gadget, But I think it can do more stuff than RasPI though the cost it lil bit larger. RaspPi is 35$ and BeagleBrd is 89$ A nice comparison between both those two credit card size Linux Computers can be found here:
And finally i wanna thank my friend "Harsha Kumara" who provided me his awesome gadget to play with it for couple of days! Thanks harsha!

Finally i was able to blink a LED on my Arduino through an Android app. Well! it was a really glad moment for me. :-D
I have used a cheap Bluetooth module called RS232 BT Module even you could use this one as well.
On bluetooth, Pair them-- default password is: 1234
My BT device name was recognized as : "Linode"
