This is an Arduino Mega 9DOF Bluetooth Shield.
On http://benshobbycorner.nl you can find a small movie how it is working.
Have fun

Whoa, that looks impressive. I'm impressed it (presumably) all worked first time!
A lot of expensive kit on that shield.

45 dollar for the sensors (Sparkfun), 12 euro for the Bluetooth module (www.tme.eu). Board made at www.pcbcart.com And yes first time all working. C is not my native language so I am struggling with bluetooth to get that part working. Arduino 9DOF AHRS code from Sparkfun is working however.

That's not too expensive. Bravo on it. It looks great!
I can imagine the bluetooth code would be tricky but I have never used bluetooth with an arduino.

Code is on my weblog at this moment… 
We had to put some delay between the characters to get it working.
When the bluetooth module is programmed it takes a few seconds to pair…

Bluetooth working on the Arduino Mega 9DOF Bluetooth Shield. Had to put the BTM-112 in slave mode, and had it communicate on 57600 baud. Wrote a small program to put it as slave (ATR1), and with a ATL4 you put it on 57600 baud. And while I was busy with an ATN= I have changed it's name. After that you have to cycle the Arduino Mega power and the new settings are working. On your PC or Laptop do a discovery of Bluetooth devices and you will find your Arduino Mega 9DOF Bluetooth. If you have not changed the PIN-code, with a 1234 your will get a connection. An invisable wire? We bought the module at http://www.tme.eu , before they had only a class 1 and a class 2 module, but after a check today we have seen there are a lot of new modules. In the 9DOF AHRS Arduino software change all Serial.print into Serial1.print, make the bluetooth connection to your PC or Laptop, change the Python (IMU_Razor9DOF.py) lines to get the right COM-port on 57600 baud and of you go? Will make a new movie tomorrow?

Just reading your blog! Good stuff. Long time microcontroller user :)

Display working on the Arduino Mega 9DOF Bluetooth. A Nokia 6100 (Epson). 132 x 132 pixels. Had to make a small DC-DC step-up converter to make 9.5 volts for the backlight from the Arduino 5 volt.
