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.

It is running the daemons for the notification board , Orange_led_strips and National Rail clock - these are all connected to a powered USB hub.

It's also connected to some speakers so it can do the doorbot-sounds (historically GLaDOS voices) as well but this has been broken and out of use for a long time.

Hamming has 2 x hard drives in RAID1 - it has had the 'ticking drive sound of death' so this is likely a very good thing.

Useful note for crashes / restarts etc - run

 export AUDIODEV=hw:0,0

before rebooting or PulseAudio won't work.


Yvan was kind enough to purchase a Raspberry Pi 2 as a replacement for Hamming. It is running Ubuntu MATE (a nice prepackaged spin) and we installed almost all of the same packages from Hamming onto Hamming-Replacement.

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.
