In this edition i will demonstrate how to assemble your own Ubuntu Orange Matchbox: Ubuntu Branded Pibow for Raspberry Pi 2 & PiGlow. As shown below.

Ubuntu Orange Matchbox: Ubuntu Branded Pibow for Raspberry Pi 2 & PiGlow.

Basically, at the end of this blog i will demonstrate how to assemble your own Ubuntu Orange Matchbox: Ubuntu Branded Pibow for Raspberry Pi 2 & PiGlow. Flash it with latest Snappy Ubuntu Core, which has support for  Raspberry Pi 2’s GPIO & I2C. I will also managing Snap packages from Ubuntu Phone Browser & Snappy Scope (Beta). I will also share tips & tricks to enable WiFi on Snappy Ubuntu Core. At the end, i will demonstrate Snappy Ubuntu Core + Raspberry Pi 2 + PiGLow in action. PiGlow will blink LEDs, as per the CPU Resource Utilization by  Snappy Ubuntu Core.

We have divided this post in four different part:

  • Make In India: Ubuntu Orange Matchbox: Ubuntu Branded Pibow for Raspberry Pi 2 & PiGlow
  • Install Snappy Ubuntu Core @ Ubuntu Orange Matchbox: Ubuntu Branded Pibow for Raspberry Pi 2 & PiGlow
  • Tips & Tricks to enable WiFi @ Snappy Ubuntu Core
  • CPU Resource Utilization Demonstration @Snappy Ubuntu Core

Make In India: Ubuntu Orange Matchbox: Ubuntu Branded Pibow for Raspberry Pi 2 & PiGlow:

Here are the list of ingredients which i have used to cook my own Ubuntu Orange Matchbox. I have also share the link from where you can procure those stuffs in India.

  1. Raspberry Pi 2 with USB WiFi Dongle  & 5V, 2A USB Power Adapter
  2. Tangerine Pibow for Raspberry Pi 2
  3. PiGlow, It is small add on for Raspbeery Pi that provides 18 Individually controllable LEDs.
  4. Mixed Ubuntu Stickers

Assemble Raspberry Pi 2 with Tangerine Pibow.  Remove white laminate plastic sheet of closing cover of Tangerine Pibow.  This actions will give you transparent Pibow for Raspberry Pi 2.

 

Now, it’s time to give Ubuntu Branding. Just stick transparent Ubuntu Logo sticker on  transparent Pibow closing cover. You can also install PiGlow before closing the cover.  If you know any laser engraving service provider for metal / plastic, consult them and get your Ubuntu Branding engraving on transparent Pibow closing cover. But my trick will give you Ubuntu Orange Logo 😉

 

Final Version:

 

Install Snappy Ubuntu Core @ Ubuntu Orange Matchbox: Ubuntu Branded Pibow for Raspberry Pi 2 & PiGlow:

Recently, Snappy Ubuntu Core get latest updated for Raspberry Pi 2, which has latest updates & upgrades. Please follow this page Getting Started with Snappy Ubuntu Core for Raspberry Pi 2. It is having latest info and procedure to play with Snappy Ubuntu Core @ Raspberry Pi 2. You can even build your own image.

Here is sort summary to do the same. Get 4 Gb Class 10 micro SDHC Card. Format it and flash it with latest Snappy Ubuntu Core image.

# Note: replace /dev/sdX with the device name of your SD card (e.g. /dev/mmcblk0, /dev/sdg1 ...)
wget http://people.canonical.com/~platform/snappy/raspberrypi2/ubuntu-15.04-snappy-armhf-rpi2.img.xz
xzcat ubuntu-15.04-snappy-armhf-rpi2.img.xz | sudo dd of=/dev/sdX bs=32M
sync

Now, boot your Ubuntu Orange Matchbox with Snappy Ubuntu Core. Default Username / Password is ubuntu / ubuntu. You can manage Snappy Ubuntu Core web store through Webdm, by pointing your browser to Ubuntu Orange Matchbox IP:4200 or webdm.local. Make sure that you are connected to LAN.

Tips & Tricks to enable WiFi @ Snappy Ubuntu Core:

Snappy Ubuntu Core has inbuilt support for Ethernet port, So, connecting your Raspberry Pi 2 to LAN will get LAN IP from Router. Since, this is headless device, you can always do SSH from your host machine if you do not want to connect it with separate monitor.

It does not have support for WiFi. Here are the steps to enable WiFi and add support for USB wi-fi adapter, having Ralink RA5370 chipset. I got this with my Raspberry Pi 2 kit, please check chipset for your USB wi-fi Adapter, you may need different firmware.

Please follow this solution @ Enable WiFi with Snappy Ubuntu Core. You may need to get below package instead of  – wpasupplicant_0.7.3-6ubuntu2.3_armhf.deb

wget -c http://ports.ubuntu.com/pool/main/w/wpasupplicant/wpasupplicant_0.7.3-6ubuntu2.4_armhf.deb

I would also prefer to install nano for better modification of WiFi SSID configuration in future. Get it from here.

http://ports.ubuntu.com/pool/main/n/nano/nano-udeb_2.2.6-3_armhf.udeb

 

CPU Resource Utilization Demonstration @ Snappy Ubuntu Core:

Now, it’s time to demonstrate CPU Resource Utilization through PiGlow.  It is small add on for Raspbeery Pi that provides 18 Individually controllable LEDs. We will feed CPU Resource Utilization such a way that it will glow more when we have more CPU Resource Utilization. As i said erlier, recently we got GPIO & I2C support on Snappy Ubuntu Core, it is possible to do the same. And we have snap package available from the same, called PiGlow Top.

Access your Snappy Ubuntu Core from WebDM or CLI through SSH and install PiGlow Top snap available from Snappy Ubuntu Core Web Store. After installation, we need to grant access to I2C hardware, do the same over SSH.

sudo snappy hw-assign piglowtop.kyrofa /dev/i2c-1

Now it’s time for the demonstration, grab your Ubuntu Phone, access the Snappy Ubuntu Core Webdm from your Ubuntu Phone Browser, Do some activity to increase CPU Utilization, for example Install / Remove any snap from Snappy Ubuntu Core Web Store. I have prepared small video Demonstration for your reference.
