keg tracker

I've ordered all of the parts for the control circuit for an as-yet-unnamed addition to a kegerator that will use RFID-enabled mugs and a flow meter to track how much each person drinks, and continually update a leaderboard online.  This will be based on a Raspberry Pi instead of my usual arduino core because it's significantly cheaper and easier to hook up to the internet, and because it will only need a few output pins but (compared with normal arduino code) a lot of processing power to make requests to an external server.  In addition, this should be a pretty simple introduction to using the Pi, which will make it easier to use in future projects where its increased power is absolutely needed.
I was tempted to add a touchscreen, as well, but I decided against that as it'd singlehandedly double the cost of the controls.  I'll probably come up with an excuse to use one sometime soon, though.
I still need to build the actual kegerator, as well.  I'm working on tracking down the parts for it on the cheap and I'll post pictures of it as I make it.
