Raspberry Pi
1/1/2013 Happy New Year!
Today I am thinking that this will be used as a car computer.
I got a heavy duty 7 port USB hub for it, a nice cast al box, and now I want to make it work with my Lilliput 7" DisplayLink monitor.
To do that I will need to compile a kernel (ugh! back to doing that again!)

Following Mitchtech kernel compile instructions with a few variations. I am using Linux Mint 14 as my build host. This installs the newest (4.7) compiler and creates symlinks. This step (building a working ARM tool chain) used to take days to figure out. Ah, progress! I love the Linux world I live in!
sudo apt-get install gcc-arm-linux-gnueabi git-core ncurses-dev

Zoom zoom away we go. Put SD card in Pi. Connect monitor and boot. Worked on first try for me! Fabulous.
