Raspberry Pi

Ok you heard about a $35 computer. Well depends on how many spare parts you have lying around. So technically, its $35 and some parts.


  • Identify how you are going to use it. You may need a 32 GB Class 10 SDHC. The SD card is your hard drive (HDD), unless you mount an external via USB.
  • You will have to understand another operating system (OS). This is not Windows or Ubuntu. You will have to use command line interface.
  • You may have to install the OS more than once. Persistance wins. This is a do it yourself project.

Parts for Model B:

  • The raspberry pi. I bought the Raspberry Pi Model B Programmers Kit from Micro Center, If they were in stock I would have bought the Raspberry Pi Model B Starter Kit. Both are above the $35 but you will need a power supply and a SDHC card.
  • SD card. Don't buy any 8GB, use this list. You will want a Class 10 and I recommend 16GB.
  • Power supply, make sure it is at least 700mA at 5V.
  • USB wired keyboard. You can go wireless, results may vary.
  • USB wired mouse. You can go wireless, results may vary.
  • Display / monitor.
  • Cable to connect your display to the HDMI input on the pi.
  • Speakers, if you need sound.
  • Cable to connect your speakers to the 3.5mm input on the pi.
  • Network cable.
  • If you do not have all of these parts lying around, then you may want to consider Raspberry Pi HDMI Cable Accessory Kit
  • USB Powered Hub, depending on what you are going to plug into it. You may wnat to use this list.

What to do:

  • Don't plug it in, not yet.
  • Skip this step if you have a SDHC card with the OS on it. Install OS on the SD card using a non-pi computer. I was unable to get their formatting tool to work, so I used Microsoft's. I chose NOOBS Lite.
  • Assemble the parts.
  • Plug it in.
  • I chose Raspbian. The install will take a while.
  • Once you get to the configuration screen
    I recommend leaving the Boot to Desktop alone.
    Set the time zone in internationalisation options.
    Set the hostname in Advanced Options.
  • Default username and password.
  • Should be at command line.


  • startx
    This starts your graphical user interface (GUI).
  • sudo fdisk -c /dev/mmcblk0
    This displays how your SD card is formatted.
    For example: Disk /dev/mmcblk0: 4012 MB, 4012900352 bytes. Pi thinks this a 4GB card.
  • df -h
    Show in human readable format my disk usage.
  • sudo shutdown now
    A proper way to turn it off.
