Raspberry Pi First Impression

Raspberry Pi is a revolutionary piece of gadget that introduced to the computer arena back in 2006. Even though the concept was there from 2006, the actual commercial board was available from February 2012.

The board is little bit larger than a credit card. Currently there are two types of board available, Model A and Model B. Key differences of the two are as below:

Model AModel B
1 USB port2 USB ports
No EthernetOn Board Ethernet
200MA Power700MA

It contains an ARM11 processor that'll operate in 700MHz. A GPU (which shares memory from RAM) that capable of playing HD quality video. A HDMI port as VGA technology is getting old now ;).

Couple of my friends were doing a superb demonstration of WSO2's product stack running on a R-Pi cluster during the WSO2Con 2013 London. It was a cool project. That's the first day I saw R-Pi in action. I was so interested and wanted to get on hold of a one soon. After couple of months of WSO2Con, I went to Azeez and got one of the boards he used for the demo with a pre-installed SD card.

I did not have a USB Keyboard at that time. But the Pi's network were preconfigured by Azeez and I could see the IP of the Pi. Managed to ssh to it by connecting directly via a Cat 5 cable. By just doing a 'startx', I could start the graphical display too. Well, that was easy.

Then I managed to share the Inernet connection from my Laptop with the Pi with IP Forwarding and iptables. Then wondered around Raspberian OS. My first impression of this gadget was awesome!

I will be preparing another SD card from scratch to experience the process and see what more this tiny can do.
