Here's just a quick and dirty update on what's been going on lately with the controller. I did some rethinking about the enclosure scheme and decide to fit as much as possible into one box. All the new schematics, parts lists, and such have been uploaded. I'm currently waiting on a few parts to prototype the dimming and especially the pH circuits. I've also started working the UI, focusing on low level controls i.e. buttons.

Here's what I've got so far. This is the general layout of the main "overview" screen, obviously missing a lot of components.
