In addition to a Raspberry Pi to run reef-pi, we'll need a controllable power strip and some ancillary electronics for the control circuit. The control circuit will be built on top of a PermaProto HAT and will be connected to different connectors using jumper wires. The PermaProto HAT and all the connectors will be mounted on the plastic enclosure using standoffs.
