The Adafruit.com site is both a good site for purchasing your Raspberry as well as a welth of components for any type of project.

There is as well a lot of very good tutorials, but this time I would like to hint of their Alpha-version of a very nice Python development environmen.

The Adafruid WebIDE installes on the Pi and then you access it via your browser. Key advantages:

  1. Source file editor via a browser. Not need to ssh into the device and use vi or nane. Works with Safari on the Mac, but is optimized for Firefox and Chrome.
  2. Run and debug from within the browser IDE.
  3. Integrated support for source-code handling via Bitbucket. All your files are saved and versioned with a free personal account at Bitbucket.org.

The IDE even has event management feature that allow you to schedule program snippets to run at specific intervals.

Raspberry Pi corrupt SD Card

Raspberry Pi with breadboard connected as well as hdmi out and the Pi Camera.

This afternoon there was a power outage in our area an consequently, the Pi was powered off without a proper shutdown command.

I thought this is not a problem, since I used the DiskTools on my Mac yesterday and make a disk image out of the SD Cards.

However, trying to restore from that image into the SD Card did not work :-(
