This laptop could be the next educational gadget for your kids or students. You can use it to explain for them in action how computers work and what do they consist of. It will give them the chance to think deeper in the fields of electronics and programming while assembling the laptop for the  first time and if any trouble occurred  and they have to help in solving it. This educational benefits of TERES I could not be available unless the laptop is completely open source.

It is true that the specifications of this laptop may not be perfect, but no one can deny that the price tag is cool making this laptop a consumable choice for some usages. This DIY kit is out of stock now as mentioned on the website, but you can register your email on the product page to be notified once it is available.

TERES I is completely designed with KiCAD FOSS, also hardware and software source files are available on Github. Also check this file to know more details about the laptop and the building instructions.

A few months ago, Tsvetan Usunov the brain behind Olimex had conducted a talk at Hackaday Belgrade conference about his upcoming DIY laptop kit. Check it out!

Getting Started with Orange Pi PC 2

  1. You need to get these accessories to start using your Orange Pi:
    TF card (minimum 8 GB), HDMI to HDMI lead or HDMI to DVI lead (for monitors with DVI input), AV video lead, DC power adapter, keyboard and mouse, plus Ethernet cable/USB WiFi and Audio lead as an option.rms
  2. Prepare your TF card
    1. Insert your TF card into your computer. The size of TF should be larger than the OS image size, generally 8GB or greater.
    2. Format the TF card. (using this tool for Windows, and some commands for Linux)
      1. Run fdisk –l  /dev/sdx command to check the TF card node.
      2. Run umount /dev/sdxx to unmount all the partitions of the TF card.
      3. Run sudo fdisk /dev/sdx command to configure TF card. Use o command to delete all partition of TF card and use n command to add one new partition. Use w command to save change.
      4. Run sudo mkfs.vfat /dev/sdx1 command to format the new created partition of TF card as FAT32.
        (x should be replaced according to your TF card node)
    3. Download the OS image from the Downloads webpage.
    4. Unzip the download file to get the OS image
    5. Write the image file to the TF card using this software on Windows and this command on Linux: sudo dd bs=4M if=[path]/[imagename] of=/dev/sdx (x should be replaced according to your TF card node)
  3. Set up your Orange Pi PC following the steps in the diagram
    sketch_map_pipc_en
    Note : Avoid using the micro-usb power connector, because micro-usb power does not supply power.
  4. Shut down your board
    You can use the GUI to shut down the Orange Pi PC2 safely or just run this command in the terminal:  sudo halt or  sudo shutdown –h now
    This will shutdown the PI safely, (just use the power key to turn off might damage the TF-cards file system). After that you can press the power key for 5 seconds to turn it off. Full guide and any updates on the OS image will be available here.

This open source SBC (single board computer) is a great option to start building IoT devices, DIY projects and for development purposes. You can use it as a mini-computer, a wireless server, music and video player,etc. You should remember that the limit is the sky when it comes to open source boards.

The Orange Pi PC 2 is up for sale on AliExpress and you can get it now for $20. You can apply for free products from Orange Pi through this application by defining your purpose of using the product and following the steps mentioned here.
