[Jason Kridner] is a member of the i3 Detroit hackerspace and during the Hackaday meet-up we were able to spend a few minutes talking about what’s going on with BeagleBoard right now. For those of you that don’t know, BeagleBoard is a non-profit foundation which guides the open hardware initiative of the same name. This includes BeagleBone which is the third iteration of the platform. [Jason’s] a good guy to talk to about this as he co-founded the organization and has been the driving force in the community ever since.
Right now the organization is participating in the Google Summer of Code. This initiative allows students to propose open source coding projects which will help move the community forward. Students with accepted proposals were paired with mentors and are paid for the quality code which is produced. One of the projects this year is a 100 Megahertz, 14-channel Logic Analyzer which [Jason] is waving around in the video. It’s the GSoC project of [Kumar Abhishek] and you can learn more from his proposal.
Also of interest in the video is a discussion about the power of the BeagleBone’s PRUs, or Programmable Real-Time Units. They’re basically unused microcontrollers that have direct access to a lot of the processor’s features and are just waiting for you to bend them to your will. Having these is a huge boon for hardware hackers. If you haven’t played with them before, check out our earlier article on what PRUs are all about and then give it a whirl yourself.
After the break there’s a brief table of contents which maps the topics in the video above.

[Matlo] wrote in to share his USB sniffing project using the BeagleBoard-xM. It builds on the Google Summer of Code project from 2010 that used the non-xM version of the hardware to build a pass through USB sniffer. [Matlo] couldn’t get it to work back then, but recently revisited the project. He’s cleaned up some scripts and generally made it a bit easier for others to pull off as well.
The ARM-based BeagleBoard seen above acts as man-in-the-middle. You connect your target USB device to the board and the board to a computer. The board emulates the target device, passing packets in either direction while also logging them. The captured data is in the correct format for display using WireShark, the de facto standard for making sense of captured communication packets.
This is great for figuring out how to use USB devices on non-standard systems, or vice versa.
Imagine a tiny little device that you velcro to the back of your TV that delivers all of the media found on your home network. We’ve been dreaming about that since we saw early working examples of XBMC running on a Beagleboard. We’ve heard little about it since then but now there’s cause for hope. XBMC optimization for the Beagleboard has been approved as a Google Summer of Code project. The fruits of these projects tend to take a year or so to ripen, but we don’t mind the wait.
[Topfs2] is the student coder on the project and will be posting weekly updates as well as idling in IRC so if you’re interested in lending a hand with testing or words of support you should drop him a line.
