After lots of requests from folks wanting to use Loki's code and hardware designs with Arduino, I have converted Loki's sensor interface from a PIC processor board to Arduino Mega 2560.
Check out the new interface shield schematic and source code at:

This might also be useful for anyone wanting to create a PC application that needs to controls external hardware and get sensor feedback.
Hope this is helpful for folks!
