Playing With Raspberry Pi (Part 1) : How To Install an OS to Raspi

I know maybe it’s already too late for discussing raspberry pi (raspi) but hey, it’s my first time touching this little one and playing with it. I’m not gonna write the history behind or anything related but i’m gonna share my experience. Actually this is not my own raspi, my friend gave me. He has a project related with raspi and python, some kind of robot project. It’s because he doesn’t have python knowledge so he asked me to do some research with his raspi. So first we have to know what kind of model, how much memory and so on. I’m in hurry so my first target is to install raspi (yeay!) using operating system that available on the site. How about the models?, how much memory this raspi have ?. We’ll talk about it later.

Okay my choice is Arch Linux. Why ?, Smaller size than Raspbian. Actually there is another one like RISC OS but i’m afraid some packages are unavailable to download or modify or there is too much dependencies but the choice is yours. The other reason is because I have slow internet connection :). That’s all. Remember, raspi using SD Card for installation. So prepare your SD Card, Image OS (choose your own OS and download from http://www.raspberrypi.org/downloads/) and Win32 Disk Imager (download from http://sourceforge.net/projects/win32diskimager/).

Ok here is my raspi from Element 14. Figure 1 in the box and Figure 2.

 Installing OS to raspi is very simple. First, we have to format SD Card and injecting the image. Insert the SD Card into your notebook (assuming your notebook has SD Card slot) then open the win32diskimager like this Figure 3.

Browse your downloaded image and don’t forget to point into the right device. BEWARE !, WRONG POINTING DEVICE can ruined your notebook drive. After that push the “Write” button and wait until the process is done. If the format successfull we can forward to the next step. Insert the SD Card into the back of your raspi like Figure 4 here.

There are 2 ways to display your raspi on a monitor or TV. We can use RCA cable to connect to TV or we can use HDMI connector. Because I don’t have any HDMI cable so I choose RCA cable. The RCA cable are the most common cable so I hope you can find it in the general store or any store that sell electrical appliances. The RCA cable is like this in Figure 5.

The cable has 3 connectors, i’m using the yellow one. Plug in into your TV (find the the yellow hole in front or back). Prepare your USB keyboard and mouse to configure. I only use USB keyboard though :). Okay the last one we plug the power cord. And here is the alarmpi (Arch Linux Arm) in Figure 6.

Login to the shell using root and password root. Tada !, congratulation. That’s all for now.
