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

HAL Diagram


References

HAL's name comes from the movie 2001: A Space Odyssey. It stood for Heuristically programmed ALgorithmic Computer. At MAG Laboratory, we know it as HAL is Always Lying as both a reference to the movie and to the bleak reality which surrounds us.

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.

Maintenance Notes

HAL Enclosure

Written 2023-10-04. The new HAL enclosure with the screen requires the entire raspberry pi be removed before maintenance. This is because of a design oversight and may be resolved by the time another internal electronics mounting board is developed.

Additionally, not all standoffs inside HAL are threaded with loctite or any other thread locking compound, so removing things from the standoffs may not be advised. This is also to be fixed by the time another internal electronics update is completed.

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
