If you haven’t heard Raspberry Pi has released PIXEL the latest edition of Rasbian. It comes with a new look with new icons, wallpapers & user interface. Also included are some new additions to the software like Chromium web browser, RealVNC & senseHat emulator.
You can download PIXEL from the Raspberry Pi website and burn the entire image to your SD card following the instructions here.
However, if you have been using your Raspberry Pi for a while you probably have a lot of files like those awesome Scratch projects and Python scripts you have been writing. So an update is a likely choice for you. If you are going to update, I would highly recommend making a back up of your files first. You can make a full backup using the instructions here. Alternatively, you can drop and drop your files onto a flash drive.
Updating is as simple as opening up terminal and entering the following commands
sudo apt-get update
sudo apt-get dist-upgrade
If you are updating and not doing a new install, you will need to run these commands to install some of the new software packages included with PIXEL.
sudo apt-get install -y rpi-chromium-mods
sudo apt-get install -y python-sense-emu python3-sense-emu
sudo apt-get install -y python-sense-emu-doc realvnc-vnc-viewer
You will need to reboot for the update to take effect.
We can’t wait to hear what you think about the update.
Our next set of classes start this weekend. We are going to be using the newest version of Raspbian out nicknamed “Jessie” after the yodeling cowgirl from Toy Story. There are quite a few interesting features that we are itching to try such as the new version of Scratch which has a new GPIO server built right in!
Looking forward to playing with the new Java environments, Blue J & Greenfoot, the Libre Office Suite and the new screen capture feature to be able to share our work on the blog.
How do I get Raspbian?
How do I install Raspbian on my SD card? (mac)
It’s best to start with a clean image. Once the image file has been downloaded, plug in your SD card and open up Terminal
Identify the partition of your SD card
in this example my partition is on /dev/disk2
Unmount your SD card
diskutil unmountDisk /dev/disk2
Format your SD card (the SD card needs to be formatted in FAT32)
sudo newfs_msdos -F 16 /dev/disk2
start the copy (my disk image was named 2015-09-24-raspbian-jessie.img and is in the Desktop folder
sudo dd if=~/Desktop/2015-09-24-raspbian-jessie.img of=/dev/rdisk2 bs=5m
The process should take about 10 minutes, make sure you eject SD card properly before removing from your Mac.
Insert card into your Raspberry Pi and boot as normal.
Let me know how it worked for you.
