+## Power distribution
+
+The LEDs in the roof run on 5V power.
+
+Power to all LEDs is distributed using a set of speaker cables. The three PSUs
+share a common negative rail with a separate cable going between them. The cable
+between the LEDs is cut between the power distribution lines to separate the
