Build A Gas Guzzler Meter
Pain at the pump continues to reach new levels of misery every day. While most of us can’t afford to trade our current gas guzzler for a more fuel economical model, it would be nice to adopt some new driving skills that will translate into greater fuel economy. But where do you start? How do you know if your current jitney is a fuel sipper or a gas guzzler?

Here's a page with pics: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1223765576/0#0 The code is a little clumsy though; it's a bit slow (maybe if it used a 20Mhz crystal it would be faster...?), and the readings are REALLY off...It's neat though, and to some extent pretty cool; I still think the code could use some revising though...
