Cerberus is the 3-screen display board currently located outside the clubroom by the door.

UCC Machine History

Cerberus is was donated to the clubroom in 2015 from the UWA Business School. It sat around outside before it was installed with it's previous setup by [BG3] and [TBB].

Since a reinstall done by [FVP] in February 2018 the machine now runs Linux using nodm (display manager) with matchbox (window manager) and Firefox to display a custom webpage for the content.

Current Machine Tasks
