Here is some results and comments on the first overnight deployment.

Details and findings:

• 1 minute interval time-lapse was set
• Pipecam was rested on a small reef on the edge of a kelp forest .
  • ~2m depth
  • Resting with a 3kg weight belt
• Cronjob set up to operate only between day light hours which is roughly 07:00 - 19:00 at the moment, which looks like this: 

  * 7-19 * * * script.py >> output.txt

• Was recovered with no damage or leaks
• The pipecam ran for about 25 hours before running out of power. 
• The timezone of the pi was not the same as the cron, leading to a 2hour discrepancy
• About 2.7 Gb of photos was recorded, which in this case was about 660 photos
• At least two groups of divers found the camera at the location
• Fish are very interested for about the first hour of deployment

And here is a video of the results:

Some conclusions:

• Needs better identification signage for passing divers
• Add STATUS Led to easily see that the project is still alive
• Check timezone and sunrise/sunset times with pi timezone
• Project is way more power hungry than anticipated (probably the USB hub adding more power than expected)
• Kelp forests are pretty, but they make for VERY busy time lapses and is better suited for video
• A night time deep sleep will score another ~12 hours on the current setup

Now for some bench tests before we put it in the water again.
