Nice Project! I think I have over half these items in my basement after my Aquaponics project. I wonder if there are cocktail competitions in Canada.

Aluminum to steel is subject to https://en.wikipedia.org/wiki/Galvanic_corrosion. I suggest plastic washers to separate the metals.

Nice build. I've been using the SparkFun ESP8266 for my solar projects. It includes a LiPo charge circuit that works without any programming. It's $2 cheaper that the Adafruit charger board but quite basic. https://www.sparkfun.com/products/13231

Nice comprehensive project. I would suggest skip the LCD and use the bluetooth. I really like http://appinventor.mit.edu/explore/ for doing Android apps and remote monitor temperature and voltage on other Arduino projects I've done. I've also sprouted plants by a window and used NeoPixels to supplement in the evenings. I'm not sure what spectrum I end up with but generally full R and less G and B. Sounds like I should go full B and half or less G

Pin 2 and 3 are TTL serial. I believe a standard RS232-C cable you can get for USB will damage the inputs. You really need a Arduino Uno to program since it already does the USB to TTL conversion plus the Arduino IDE has all the functions to load the bootloader and program the chip.
Z80 and CP/M. Those were the fun days.
