BeagleBoard Contest

The first ever BeagleBoard design contest has ended. The top 2 winners recieved a BeagleBoard Rev C1 as their prize. The BeagleBoard revision C1 has a working USB HOST and the newest OMAP3 silicon revision. The winners are recieving their boards 2 month before it is made publically available by DigiKey, in March of 2009.

The winning design was the BeagleBot, which essentially dodged walls and obstacles. The projects entered into the contest can be found at This cite also provides information on the contest, judging criteria, and judging results.

The second contest's dates have not yet been decided on, but it is said that the deadline will be no earlier than February 12th, 2009. We encourage everybody to enter a project in the next contest. I look forward to seeing all of your creative and innovative designs.
