Have any used an Arduino for logging information?

Have any of you used an Arduino to log information from multiple sources? 

I am thinking something like logging the 5V output on the tach and the 5V output on an A/F gauge, and any other 5V outputs one might include.

It seems to me this might be a very inexpensive alternative to some other ways to tackle this.

Any help will be greatly appreciated.

I have not thought about using one for data logging - although I use them for some other small projects. I bought a whole mess of thumbnail sized Arduinos specifically for adding features to my cars.

Thanks.  I still need to get the power set up for the Arduino (something lost in shipping).  I will let you know whether I manage to make it work. I haven't done anything with it yet....
