Hamming is an x86-processor based VIA EPIA based system donated by [[User:Aden]]. It is old and was once doorbot. It ideally could be replaced with a modern Raspberry Pi 2 or Beaglebone Black.

We're hoping to use a PoE power adapter for remote power management of Hamming-Replacement but retain the powered USB hub for the various serial devices. This will be a much more flexible, power efficient system with less moving parts.

Documentation on the 'moving bits' will be forthcoming.
