Art installation uses a Raspberry Pi to show how stupid people can be with their data

Martin Hertig from Switzerland has created an art installation called “Sensible Data” that shows just how easily people give up personal data, and what the pitfalls of that are. You use an iPad to take your photograph and give your email address. The photograph is scanned by a Raspberry Pi to work out your age, gender, ‘beauty’ and mood and this information is then printed onto a faux “passport” for you to take away. The printing is triggered by holding an unidentified button for three seconds… which grabs your fingerprint… To hammer home the point of the lack of control of personal data, you are then emailed the details of a previous participant. You can read more about the installation here and see it in action below:

Pyrite sun discs used to create music on the Raspberry Pi

Dmitry Morozov is a Russian “media artist” and has created this wonderful piece of artwork. Using a custom laser set-up, he scans the discs of pyrite, produced on this planet seemingly only in Illinois, and then sends the data through to the Raspberry Pi which filters and transforms it into a sound wave, which is played through a speaker. You can hear the output and see the apparatus which controls speed and direction below:

Cannybots Kickstarter launched today – includes Raspberry Pi support

Cannybots, who are a regular at the Cambridge Raspberry Jam, have been working on their product for 18 months now. During that time, they’ve gone through several iterations of the product and introduced it to several schools in prototype form. The Cannybot is a motorised car that comes in a plastic body and is packed with features, the major one of which is line follower sensors allowing it to zip around courses at high speed. It is programmable via Bluetooth and supports a whole range of modes allowing you to use it to drive speed courses, take part in sumo and jousting, navigate mazes, among others.

Today, they have launched their Kickstarter campaign. I won’t go into all the pledge levels here, but they start from $89 for a single Cannybot (Earlybird price) and go up into the lower stratosphere for the larger and more customised packages. Here is their campaign video:

There is a wealth of information on Cannybots on the Kickstarter page so head over there to read all about it. Most importantly for us lovers of the Raspberry Pi, they have developed support for the Pi so that it can be programmed from any language that has ‘sockets’. This includes Scratch, Python and even Sonic Pi. They have created a Python library for programming the robot and all you need is a Bluetooth dongle to connect to the Cannybot. More information on how it ties into the Pi can be found here.

They’ve clearly worked very hard on this product so, if you’d like to have motorised cars driving all over your living room or classroom, take a look!

New version of Raspbian for the Raspberry Pi – moves to “Jessie”

Exciting news on the operating system front this morning.

Raspbian, the standard OS for the Raspberry Pi, now uses the Jessie version of Debian as a base. This has introduced several new improvements, chiefly among which are:

  • sudo-less GPIO access
  • User interface improvements, including the replacement of raspi-config with a GUI version
  • Two new Java programming environments
  • Inclusion of LibreOffice as standard (for better or worse!)

More information on the improvements can be found on the Foundation’s blog.

The 4.3GB image is available as a download from the Raspberry Pi Foundation.

It is recommended that you start with a new install (i.e. overwrite the SD card completely) as the upgrade path isn’t all that stable. This could prove a problem for some users, who already have stuff on their SD cards they don’t want to lose, but I’m sure the benefits outweigh the effort of transferring your stuff elsewhere first (for instance to GitHub).
