| The task at hand is to build a current and voltage data logger that will assist other students with their endeavors in the lab. Commercial, off the shelf data loggers exist but are often proprietary and closed source. We have a unique opportunity to build an open source data logging platform that can serve as an educational tool for other students in the future as well. | The task at hand is to build a current and voltage data logger that will assist other students with their endeavors in the lab.

| Think about how we can build something that will be of benefit to the most people. Someone should ultimately at the end find some use out of the tool - polishing of the tool, regardless of hardware or software can be accomplished after we have something that is done. | Think about how we can build something that will be of benefit to the most people.

The various block diagrams will also be used for the presentations. | Note that some of these things may overlap with each other.
