Open source datalogger for video sync

This is a device that I put a lot of effort into, and it is still a work in progress. I spent months assembling hardware, and almost a year writing the program. After launching an instructable on how to assemble it, as well as publishing a github repository to share the code and invite collaboration, I’ve gotten considerable interest in the project. So what is this thing?

An Arduino based datalogger for the purpose of syncing data with video to create an on screen display.

In other words, you are riding your (bike, sled, trike, car, feet, board, etc.) and you have a portable action camera such as a gopro hero, and you want to put a dashboard of gauges on the video that tell you all relevant information about your ride.
