Raspberry Pi

The Raspberry Pi project is really interesting. It’s an attempt to make a low-cost, (mostly) fully-featured ARM box in a format roughly the size of an Arduino. The computer itself has some impressive specs:

  • 700 MHz ARM processor
  • 128 MB RAM
  • SD card reader
  • 2 USB ports
  • HDMI out
All this for $25 (another $10 doubles the RAM and adds an Ethernet port)! Here’s a video of the Raspberry Pi playing Quake 3:

I could see a device similar to this being used as a “clean computer,” deployed in situations where security is important and there is a risk of existing computer systems being compromised (such as voting, or maybe for test-taking, or computer forensics?). In addition, I would absolutely love to take one of these around with me to use as a swiss army knife (server, router, streaming radio, office, etc.) once it’s got a nice case. Perhaps 3D-printed for a buck?

The other thing that interests me about these computers is their low power consumption. They use less than a watt of power, and while they’re currently limited to an AC adapter (included with the device, I believe), I’m sure that in no time people will make battery packs for them. Include a wireless USB dongle, a Twiddler (currently USB, hopefully soon a Bluetooth version will come out), and some kind of display, and you’re looking at a wearable computer that might actually be wearable.

I’m getting excited just thinking about it.
