I can haz data?

I finally managed to get my arduino to log data to a SD card. I've also previously read the value from a real time clock (RTC) module, and a temperature transistor. Now all I have to do is get all 3 working at the same time and I can log to a SD card the time and 2 temperature readings. The plan is to have a temperature reading in the capsule and outside it. I can take the time it was logged and match it up to the GPS data sent via aprs to tell what the temperature was at a specific altitude.

I also have a pressure sensor, but I have not yet tried to get that working with the arduino. Nobody has used this sensor with an arduino that I can find, so I'll have to figure out how to interface with it myself. If I can't get it working I'm fairly confident I can at least get temperature data.

My plan is to take the data from the SD card combined with the GPS data and edit the video to make said data appear like captions on the bottom of the video. That way as you watch the video it will display the GPS position, altitude, and 2 temperatures at the bottom of the screen.
