How to Update Your Raspberry Pi

login

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.

Meet Jessica

You may have noticed a new face at the Raspberry Heights Workshop.

“For the past few months, Ron Callahan has given me the opportunity of my life, because I have been able to be part of a fabulous team teaching technology.
This is one of my passions that I always wanted to accomplish, being able to teach kids is a reward that cannot be explained, just to see their faces when they see the result of their work it’s amazing.
For me being at Raspberry Heights is a great experience. Since I love technology it gives me the tools to teach the next generation and also help boys and girls to be more involved in tech.”

We are so happy to have Jessica on the Raspberry Heights team. Her nurturing manner lets the students become comfortable with the material, making it easier to learn.

Thanks for all you do, Jessica!

Make Your Own Arcade With Raspberry Pi

A few weeks ago, I was attending a political rally for Bernie Sanders at Bohemian Hall in Astoria with my daughter. We missed most of the rally, but, we had dinner and spent some quality time together. In the basement they had a Ms. Pac-Man machine and we had a blast playing together. It got me thinking about MAME and how it was so much fun setting that up on my Mac many moons ago. Of course, I realized it was time to get MAME set up on a Raspberry Pi. Not only would it be a fun excuse to play the games of my youth, but, it would be a great learning experience to use GPIO to wire up a joystick and some arcade style buttons.

For this project we wanted to use a Raspberry Pi2 model B so we could take advantage of the 1GB of RAM. Downloading the Raspicade system took a long time, but, is a great interface.

Make sure you get the correct version of Raspicade for your system. The version I had would not work on Model B, fortunately, I have a small arsenal of Raspberry Pi in my studio and found a Raspberry Pi2 model B that was free.

Most of the documentation available was for older Raspberry Pi models. I found a great article that explains how to update retraced to work with the newer Raspberry Pi2 here.

Once the software was set up, I began testing the buttons. You can find a great diagram for the pin out on Ian57’s Github page.

It was a great project and very challenging to get all the pieces together. After a few nights of research I got everything prepped and two of my students were able to wire it up  within an hour.

“Howdy Jessie” New Classes, New OS

Yee Haw!

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!

jessie

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?

download here.

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

diskutil list

diskutil list

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.

Some useful items USB micro SD card reader, Micro SD card adapter and of course the micro SD card.

World Maker Faire 2015

Thanks to everyone that stopped by our Maker Faire booth to say hi!

kids

Our second year at Maker Faire was a total blast. We had visits from current students, alumni and a couple special visits from Matt and Phillip from Raspberry Pi Foundation. We met teachers, droids, craftspeople, technologists, drone pilots, multimedia artists and makers of all agesscratch class

We had the opportunity to teach a scratch project to dozens of young makers all weekend long.

This is the droid we were looking for.

This is the droid we were looking for. R2D2

FYI – November classes are filling up. Second class added for beginners.
