Gentoo and Kernel 3.0
I upgraded to Linux kernel version 3.0.3 today and it works!
There were some things to think about but almost everything worked like kernel 2.6.39. The main problem was the Nvidia driver which must be the newest version available. The "stable" version for 2.6 doesn't compile. I added the following to /etc/portage/package.keywords to get things run:
=sys-kernel/vanilla-sources-3.0.3 ~x86x11-drivers/nvidia-drivers ~x86
VirtualBox modules compiled without any problems and is running like before...
Just upgrade! Ask me if you need help... ;)

HP 5082-7433 7 Segment LED Display
Rafael and I found this 7 segment LED display tonight while tinkering a bit. We didn't knew what it is at first but after searching around the web we found out that it was a very vintage 7 segment LED display with 3 digits... ;) It is a HP 5082-7433.

Arduino Motion Sensor Server
I tinkered a little bit this evening and I have added a motion sensor to the Arduino platform. After that I added a network shield and have coded a small HTTP server... This server provides just a 0 or an 1. 0 if I don't have moved around; 1 if I am dancing on the desk... ;) The sensor works with a radius of about 5 to 7 meters and it is really a lot of fun. You could get such sensors very cheap at ebay, just search for "arduino motion sensor".
I am getting the status every second using wget and are displaying the output in xterm. It looks nice to see how much I am moving when writing this Blog post:
