DC-DC converter

The DC-DC converter from Carnetix should be here any day. I'm using this to power the Mac mini from R2's on-board 12V batteries. It's a device that is used to power PCs that have been installed in cars. It provides filtered power to the Mac, and allows for orderly startup and shutdown/sleep when power is removed. It even provides a secondary power output that is delayed on power up for audio amps and USB bus power.
