"Looks interesting too. I can make good guess about 3x magnetometer and 3x accelerometer
I'm wondering what gyro do they use? The IC looks quite big. Any idea ?"

Kind regards

Sergey replied to Caleb Chamberlain's discussion Best setup and pinout for 6-DOF IMU"Hi Caleb,
What is the progress with IMU? Is it ready ? :)"
Sergey commented on Tytouff's blog post IMU"Hi Tytouff,
What is your progress? Do you have something to share ?"
Sergey replied to Caleb Chamberlain's discussion Best setup and pinout for 6-DOF IMU"This is not really new - it is already on their site for several months :) ... and still not released, apparently they have some serious issues"
Sergey replied to Caleb Chamberlain's discussion Best setup and pinout for 6-DOF IMU"Ok, finish the first batch and sell it. I will buy 1 for testing.
I hope this is not the last batch you are planning to manufacture. In the next one you may use suggestions from guys from this forum."
Sergey replied to Caleb Chamberlain's discussion Best setup and pinout for 6-DOF IMU"1 - 1.5 month still not bad. I'm not in a hurry I can wait if you say you are going to make it :)"
Sergey replied to Caleb Chamberlain's discussion Best setup and pinout for 6-DOF IMU"Anyway most efforts anyway goes into software and filters tuning
I'm a software so I thought that replacing an IC is similar to putting a new dll :)
How much more time will it take you to use IDG gyros instead of ST?"
Sergey replied to Caleb Chamberlain's discussion Best setup and pinout for 6-DOF IMU"Why don't you use IDG gyros, they use high resonant frequency - 27 KHz and higher?
And I think price for them is comparable to ST"
Sergey replied to Caleb Chamberlain's discussion Best setup and pinout for 6-DOF IMU"That cool man. Exactly as I imagined.
To oversample and get extra 4 bits you would need to sample at the rate of 256 times the original rate.
You wrote that you plan to sample gyros at the rate of 250 Hz. So you have 64 KHz sampling per…"
Sergey commented on Tytouff's blog post IMU"Hi Guys,
I'm thinking of making IMU on stm32 too. I have development board + JTAG debugger for it
I'm using KEIL uVision 3.
I have a plan to use:
3x magnetometer - HMC5843 20$ on digikey (but 50$ for the breakout board from sparkfun :)
3x…"

Are you still busy ?
I have not heard from you since last week.
Sincerely,
Sergey"
Sergey left a comment for Todd Berk"Hi Todd,
Have you got my last comment?
I'm attaching picture of the concept I have in mind
Kind regards,
Sergey"
Sergey left a comment for Todd Berk"Hi Todd,
Thank you for you reply. I already though it is some sort of conspiracy against me.
I wrote to you a message last weekend from 2 forums
http://diydrones.com/ and
http://forum.sparkfun.com
Next day I could not log in to sparkfun forum - the…"

I've gotten your messages, I've not ignored you. My new job has halted progress on my projects, but I would love to share some information to help you out. I will reply via email this weekend at some point with more info. Thanks for being patient, I've got a wealth of code and information to share.
