Open Source Data Logger Project Using the Arduino?

Hi! I'm new to this forum, so I apologize if anything I say is out of context. As a mechanical engineer at a product design company, I'm very interested in a cheap data logger.

Is there a way that we can all put our minds together to create a "Product Requirements" document? There seems to be a significant amount of knowledge and ideas, and it would great if we can compile them. I'm not sure if this is the forum to make a collaborative document, but I'm willing to give it a shot!

From my brief skimming of the posts, I think that as requirements we have the following:

PRODUCT REQUIREMENTS

  1. Completely Open-Source, running off of the Arduino Hardware
  2. Portable, to record data "in the field"
  3. Able to store data to some sort of mass storage (SD, USB, etc.)
  4. Read inputs from a variety of instruments, most importantly:
  • temperature
  • GPS
  • fluid pressure
  • air speed
  • light
  • electrical inputs (voltage, current, etc.)
  1. Interface with a GUI/graphing software

I know this is a couple steps back from what some people have done, but it would be nice to have a "common goal" in our collaborative efforts!
