"I doubt that having a GPS will improve heading accuracy much since it is a pretty low frequency and accuracy source of heading.. but I'm not really very experienced in GPS to say much about it."
"Yeah, some residual drift is expected. Also note that with time it will stabilize if you held the board still.
In theory we could get rid of it by better gyro calibration with thermal compensation but that's not something I'm very interested in…"

"Alpha version of the calibration GUI released. See http://www.varesano.net/blog/fabio/freeimu-magnetometer-and-acceler...
Windows executables available."

"I've been also contacted by another ArduIMU user who also ported the FreeIMU code to the ArduIMU.
He provided me his code at http://dl.dropbox.com/u/15226597/libraries.zip
His approach has been different from Al. He modified the I2Cdev bus access…"

"Congratulations on your boards.. I obviously like purple."
"If you look at the code for the IMU fusion board, it's pretty easy to understand how the accelerometer is handled. It should be pretty straight forward to change that code to support the Kionix accelerometer. Just change the initialization to match…"
"Yeah.. I'm working on testing it just right now.. Stay tuned on my website for any updates. Meanwhile you can read this for seeing the current tests results."
"65 FreeIMU v0.3.5_MS available for shopping tomorrow!"
"Guys, thanks for the interest in the project. I only had a very limited number of prototypes available which is now out of stock. Please follow my blog I'll announce availability and progresses there. Thanks!"
"Dimitar, not problems at all! I actually appreciate you guys interest in the project!"
"John, I can't elaborate much.. the BMA180 is a very well known and good quality accelerometer, used by other projects too (FreeFlight IMU).. same for the ITG3200. The MPU6050 which will be featured on FreeIMU v0.4 is still not available so I can't…"
"Hey, that's my work! You find all the details of the board on http://www.varesano.net/projects/hardware/FreeIMU#0.3.5 .. I'm following this thread if you have any questions."
"Thanks guys for mentioning my FreeIMU project. FreeIMU is a truly libre hardware project, released under CC-BY-SA and even developed with KiCAD, a libre PCB editing software, so that you don't have to rely on proprietary software to study or modify…"
"If anyone is interested, I'm organizing a new group buy from invensense. See http://diydrones.com/forum/topics/group-buy-from-invensensecom"
Hi everybody, In the first weeks of January I plan to submit an order to invensense.com. They sells great chips like the ITG-3200 (3 axis gyro) and IMU-3000 (3 axis gyro + 3 axis accelerometer interface). For a full list and details see:…
UPDATE: project page available at http://www.varesano.net/projects/hardware/FreeIMU In the past months I worked a lot on accelerometers, gyroscopes and digital compasses. I'm now pretty intimate with the ADXL345, the ITG3200 and the HMC5843. I've…
