Default Arduino Based Keezer

Final Write-up: http://bit.ly/10Vc7wX

I decided to build a keezer, and then decided being an IT person/programmer that I should play with an Arduino and see what I could get it to do. I read a lot of threads around here to get ideas for my keezer / collar, so I figured I'd post what I've done so far (i'll post more as I progress, should be done in a couple weeks).

I plan to use the Arduino to measure how much beer is left in the keg with an LCD for each tap, as well as show the temp inside and outside of the keezer (I plan to put it on my deck for the summer). It has a webserver (ethernet shield) showing how much beer is left on each tap, and soon it will have a page where you set what beer is on each tap including name/capacity.

I know kegbot exists, but I wanted to do it all myself from scratch as a learning experience

Tonight I used a jigsaw to cut the LCD holes, then a router to make room for the PCB to fit and have the LCD be flush, drilled the holes for the shanks, and glued the whole thing together. Once the glue is dry i'll put blocks in the corners to help provide some stability.

Does anybody have any suggestions / ideas for other things I can do with the Arduino?

If you're doing it by weight, you might consider measuring how much c02 you have left - warn you that you're almost out. If you can get a pressure sensor of some sort, you could do automatically do the volume of CO2 calculation for each gas line you've got.

Maybe a warning email/text if the temp goes above or below your thresholds.

Cool project!

Measuring the power consumption of the freezer.

I like the email alerts for the temp, that's a great idea. I'm going to use flow sensors to measure the volume of liquid (it's all written, but the sensors aren't here yet.)

A buddy of mine suggested using a Kinect and the people recognition it has (part of the SDK) to identify who is pouring a beer. I don't know how accurate it would be outdoors in changing light (on the deck), but it might be worth a shot!

Thanks! I plan to do a write-up of it on my IT blog when I'm done, including the code I write.
