Any interest in developing an open source fuel economy gauge/computer?

Are there any people here who would be interested in developing an open source FE gauge/computer?

We see lots of inquiries about the SuperMID, which works by monitoring the vehicle speed sensor and a fuel injector signal. Unfortunately, Yoshi's a busy guy, so he hasn't been building too many. And the value of the US dollar relative to the Yen is making the MID more and more expensive.


The SuperMID in basjoos' AeroCivic

I don't know much about this stuff, but it seems to me the open source Arduino computing device ($35) would be an ideal platform. The cool thing about it is that it could also be connected to a laptop/palm if desired.



Arduino electronics prototyping platform

I know skewbe @ GS developed a quick 'n' dirty FE gauge that uses a laptop sound card & audio input to monitor injector cycles, but an Arduino based system seems like it would make more sense to more people.

Doing something like this is outside my experience. I could probably figure it out, but I've got enough projects as it is.

So I'm just putting it out there to see if anyone else would want to spearhead things.

Thoughts?
