New 6dof from sparfun.

The new 6DOF from sparkfun has all surface mount so no gyros on daughter boards.

"Description: There's a lot of punch packed into this little IMU. The 6DOF Razor makes use of ST's LPR530AL (pitch and roll) and LY530ALH (yaw) gyros, as well as the popular ADXL335 triple-axis accelerometer, to give you six degrees of measurement on a single, flat board."

Wow that's really impressive.

Why can't $parky make these double sided & gyro only so they'd be real small? Autopilots haven't needed accelerometers for years.

Jack: that's news to me. Can you explain? Remember that these have to work outside of GPS reach, too.

For the wierdos who just care about flying in GPS range there should still be a 3DOF product. Obviously you'll get a lot of hate from the motion capture industry for not promoting The Standard IMU. VicaCopter used a 3DOF IMU algorithm & Neural Robotics probably did. It was more reliable than using compasses & accelerometers. The source code has always been available.

If you don't want to use the accelerometer,. then don't wire it up. This board gives one the flexibility.

I remember that a winner of a circuit cellar competition was a mortar shell that included a similar board. I can't remember whether it was guided but it was a cool project.

OK, now seriously...doesn't this just BEG to become part of an ArduPilot Shield?!?!

Don't worry--we're on it.

Some mention about ST gyro's problem with vibration due to low resonant frequency. How about this ? Has anyone tried ?

A somewhat off-topic question, but by using the LPR530, you get from 300 to 1200deg/sec angular speed, I thought about using the LPR510 which gives 100 to 400deg/sec. In your opinion and experience, what is the maximum speed one should target?

You read my mind :-)

Contests

Season Two of the Trust Time Trial (T3) Contest has now begun. The fourth round is an accuracy round for multicopters, which requires contestants to fly a cube. The deadline is April 14th.

A list of all T3 contests is here.
