			HAL's name comes from the movie ''2001: A Space Odyssey''. It stood for '''H'''euristically programmed '''AL'''gorithmic Computer. At MAG Laboratory, we know it as '''H'''AL is '''A'''lways '''L'''ying as both a reference to the movie and to the bleak reality which surrounds us.

	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.		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.
