Currently I have the following:

Pi Zero W in DIN enclosure

Wemos D1 in DIN enclosure w/oled display and relay shield

DIN on/off switch

Currently on order awaiting delivery:

DIN power supply

DIN rail

DIN brackets

In order to make this iteration of the Aquariumatic look the absolute balls I'm going to mount a rail in a small flight case on some angled brackets. This will look great for presentation and also will allow it to be really transportable.
