Wow that's great! Obviously, great job on the code!!!

What sensor ICs is that using? Any plans to release schematics, gerbers, SW? More details please :-)

bcr,
For sensor details, you will have to contact Louis Legrand. He is a member of diydrones.
The DCM firmware that Louis is using to compute direction cosines is a port of the UAV DevBoard firmware. Visit the UAV Devboard tab, there are links to discussions, documentation, and firmware. The routine that does the calculations is called rmat.c.

Well, if Louis is reading this - is the IMUDOT (with DCM) being sold?

That is FANTASTIC! Everyone should check out that video. Bill, huge congrats on the adoption of your code!

The devices we develop at Intel Research are not typically sold. They are built to facilitate the various research project that we are working on here in the lab (unfortunately no UAV's). However we do occasionally share devices with other researchers. See for example http://seattle.intel-research.net/msp/ and http://www.seattle.intel-research.net/wisp/ for examples of this kind of collaboration. I am hopeful that we might do something similar with the IMUDOT some time in the future.

Hi, that board is fantastic!
What gyros are you using? It is good having them all on the same circuit board without having to mount vertical boards.

wow that was great...hope i will be able to get something like that working!

Louis, any plans to release schematics/board plans/source? It looks like an interesting thing to try out.

From what I can see here, the only edge the Intel gizmo has over Bill's UAVDev board is the added magnetometers. Ok, it transmits via Bluetooth, great for short range but not even an option for UAV ground stations. Sure magnetos will give you extra precision but with a proper GPS u-Blox binary capable receiver, directional data is accurate enough to use in UAV applications, update rate is fast, I think we can make do without magnetos (Bill, correct me if I am wrong.)
Sure it would be amazing to have such a capable board with all those sensors but I bet the budget is above $1000.00 each. With that budget, I could buy a few ArduPilots, a UAVDevboard and a Paparazzi!
Bill's board in my opinion is the only IMU so far that has the potential to work for multiple aircraft platforms (Plane, Heli, VTOLs, Gliders etc..) without braking the $500 barrier.
Regardless, it is nice to see Bill and Paul's effort in the hands of a giant like Intel. That speaks for itself!
Kudos to both of you for coming up with such monster code!
