HAL

HAL is MAG Laboratory's motion, door, and open status monitor.

Design

HAL is based on the raspberry-pi (one) model B and uses the PI's GPIO pins to interface with the outside world.

There is a hardware design document on Google Drive.

Problem Reports

HAL-1 : "Main Door" does not describe the door being monitored

HAL-2 : Haldor Board is not Sufficiently Skookum for Safety

HAL-3 : A synoptic view should be implemented

HAL-4 : An Auto Updating Feature Should be Implemented
