Recorded run 2

Today was the day of our second recording. We started the day by setting the Arduino to trigger at 1 cm and 8 cm, however, that resulted in almost no change from the previous recorded run. The previous had been set to 2 cm and 9 cm. This is just another problem stemming from the sensor readings, which we don't have a solution ready for.

To correct for this problem, we reset the triggers to be at 0.5 cm and 7 cm. This resulted in nearly 2.5 cm of difference at the high head in real life, and a slight change int he low head. That's not great, but at least it's different from the last experiment.

I spent the remainder of the day putting assembling the frames from the last experiment into a dramatically sped up video, set at a rate of 1 minute per second. It looks nice, but I have started recompiling the video, as the video player included with Windows is bad, and won't play it. We'll see if that's sorted out now tomorrow.

Ethan spent the day working on a Matlab program to read the water level off of each frame of the video footage we have. It's a formidable task, and will take time. Related to that task, I put more thought and work into how to detect and represent the parts of the sand that turn red from each frame of the footage we have.

I'm not sure if we'll have enough time to complete either program before we present on Friday (our last day), but we'll see.

I'm not completely certain about what Sheiny did today. She kept busy, but is currently at her job, so she is unavailable to ask.
