made some cables to reduce internal cable clutter and supply power to everything. the power cable provides power to the pi through a USB plug and passes data lines through to a USB jack, basically a power injector/tee. the screen is powered through a 7805 with a voltage divider to make 8 volts, and with a laptop hinge screwed to it for a heatsink. the whole thing is fed by a 12/5 external hard drive power supply.

Howto: Compile ninepin for a 3.6.11+ kernel Assumes you already have wiringpi and whatever rt is.

cd /root

git clone git://github.com/FozzTexx/ninepin

cd /usr/src

git clone https://github.com/raspberrypi/linux.git

zcat /proc/config.gz > .config

error? Check dmesg. My issue was a missing, and then bad version of Module.symvers

BAD: [20289.345729] iec: no symbol version for module_layout
