Hi,
the Diydrohes project is testing the new   MPU6000 sensors http://www.diydrones.com/profiles/blogs/apm-2-0-release.
This Autopilot is offered  for 199$.
They have also a new version (V3) of  the ADRUIMU with this sensor:.https://store.diydrones.com/ArduIMU_V3_p/kt-arduimu-30.htm
They write that  the sensor fusion inside the sensor is working much better than the DCM.
Next year they will sell a arm autopilot.
What is about the code range  for the ST Processor ?
Ollimex has a low cost 24 Euro  PCB: http://www.watterott.com/de/OLIMEXINO-STM32-MAPLE. With the  invensense  sensor shield it seems to be possible to make the autopilot  below 50 Euro.

Yeah, let's hope it won't take as long as for the MPU6000...

Also the Aspirin2 uses the MPU6000 and the driver is already written (by
Christophe DeWagter) and already in the dev branch...

Cheers, Felix

Just posting a link to new Invensense IMU chip. 3 axis mag, accel, and
gyro in 4x4 mm package. Seems promising for lower cost future
autopilots.

Apparently will be available 4/16/12

It looks like they basically took their previous 6000 series (gyro +
accel only) and stacked a magnetometer on top of it (package is a bit
taller but otherwise the same, pin compatible).

Considering the cost of the 6000 series is about $13-$15 this could
significantly bring down the costs of autopilots in the future if the
9000 series is priced similarly.


I've played with the a microquad that uses the 6000 series and it
seems very stable.

I hope to get a paparazzi driver up for the MPU-6000 within the next
month or so, will forward any progress I make.

Andre.
