Wiimote RC-Car Control

Here in Austria the Wii is available since december 8th. At the same time the website www.wiili.org started to create a documentation about the bluetooth protocol between the wiimote and wii. It was also found out that you can bind a wiimote to a normal pc with bluetooth. All you need seams to be a different bluetooth stack than the original windows bluetooth stack. So I just purchased the BlueSoleil Stack which works perfect for me (its cheap, around 10 Eur).

To connect the wiimote you just have to press the "1" and "2" buttons at the same time. Then the wiimote is discoverable. You just have to click on the icon which appears in BlueSoleil and refresh the services. You can then connect to the new found service.

The rest was rather simple. I found some sourcecode for accessing HID devices - there I just had to make some modifications that the wiimote accellerator output was enabled.

The rest was simple. The accellerator data is computed a bit, so that it fits the needs for my PC-RC-Car Controller board (no english doc yet) which has to be connected to the serial port. This hardware creates the PPM Signal for a normal Radio transmitter (Graupner DX6 Works at 2.4Ghz.). See the video and enjoy ;-)
