Looking for an engineer who will work for beer

At any given time I usually have three beers and one non-alcoholic selection on tap in my basement kegerator, and it can be hard to keep track of how much is left in each. I've looked into various options for monitoring the levels but the best I found (the Keg-Meter) would run $400 for four kegs. Ouch.

Well, the other day I came across plans for this: a tweeting kegerator! Basically, you buy four 100-lb. force sensors and hook it up to an Arduino Ethernet Shield which sends the info to a webpage. You then use a software script to send updates to a twitter account. It seems that it would cost somewhere between $150 and $200 for everything, but how cool is that??!! Now, the problem... Even though the website gives detailed instructions for everything, I still have no idea what the hell they're talking about.

Sooooo... any engineers out there who are willing to work for beer? ;-)
