Power supplies / controller Mk3

With the addition of the singing faces this year, an extra power supply is needed. Therefore for 2017 I am using a 500W, a 400W and a 350W PC power supply as can be seen in the first picture. These power supplies connect to a bank of blade fuses which are then wired to the power strip connectors. On this panel you can also see two RonP modified 16 universe pixel controllers (1 on top of the other) and to the right of this is a wifi ethernet router.

Image 2 shows the other half of my controller setup. The Raspberry Pi connects to relays which can then switch different sections of the mains sockets. The PSUs, FM radio/speakers and the inflatables can all be remotely controlled via the FPP software. Another relay controlls the polar bear inflatable on the roof so that it can be remotely turned off in high winds.

To make better use of these PC supplies, a lot more power comes from the 12v rails and is then dropped to 5v via individual buck converters. Many of the display elements are powered from a single run of 6mm twin-and-earth for 12v and 2.5mm twin-and-earth for 5v. Image 3 shows the idea - the red line is the 2.5mm T&E (5v) and 6mm T&E (12v) with lines coming off for power to each element. The blue blobs indicate where 1 or more 5v buck converters are used.

This box of bits is basically all that is needed to power the whole show. This is placed in a weatherproof box on my garage roof.
