just put the finishing touch on my draft system: a touchscreen status display above the tap.

its running on a rasperry pi, with a PiTFT screen from adafruit:

the bezel is black acryllic cut with a hole for the screen. im thinking of redoing that with a router to recess the screen cleaner, but for now this is working really nicely.

That is great. What are the graphs indicating? and how did you interface them? Love your rocketry too.

Thanks! the graphs are showing my 4 temp sensors over time. Ive also got pages for realtime temp displays, and im working on adding a page with beer logos fullscreen.

I posed my full build on this thread:

Basically there is an arduino on the kegerator, which controls fan speed, and has 4 temp sensors. It sends temp data over USB to a rasperry pi, which serves the web UI. the new screen is just another rasperry pi, with a small touchscreen running a fullscreen browser. Its really slow to load the google chart based pages, so i may get rid of those and go to all text.
