Robo-Tank Isolated PH Circuit

[jlysaght3]

I've got the USB cables covered. My desktop computer sits beside my aquarium (on the adjacent wall) and I have a pair of USB extension cables set up specifically for programming. The only thing that is a challenge is programming the display because I have it screwed to the hood plate over my tank (so any updates that require modifying the files on the SD card require me to unscrew the screws that hold that in place).

I have also thought about other placements for the controller (on top of my hood plate, mounted inside/under the stand, etc.) but am having difficulty committing to changing it because of how convenient it is to get to now and the built-in drip loops that result from this mounting configuration (especially on a saltwater system).

I'll post up some more pictures at some point :)
