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 positive power rail from the different PSUs.

The power from the PSU is made as follows.
