Overview
For timelapses 1-3, I had multiple headaches dealing with the weak-sauce ribbon-cable Pi camera. I dumped it for a more hefty, webcam-style USB camera. Photo:
This camera is 1/2 inch in diameter.
Timelapse 4 Plan
First, let's start with what we like, and what we've accomplished:
- Several things were accomplished with RaspberryPi/Timelapse3 (example: we were able to control the LED).
- Can resurrect idea bucket, continue working on the weatherproofing ideas, now that the bottleneck has been removed (better camera)
Plan for weatherproof camera mount:
- KISS
- Mount it, use the cap that came with it, put a rubber gasket around it to protect from rain further
- Don't worry about making it bomb-proof your first time. Just get the parts working in sync.
Stuff List
Hardware list:
- raspberry pi 3
- usb jump drive (for photo storage)
- usb camera
Software list:
- script to operate camera
- necessary Python bindings for taking photos
- motion server/fwcapture?
Modifications
Modifications to the Pelican case are covered at the RaspberryPi/Weatherproof Camera Case page.
Pelican Case Modification (Success)
Successfully modified the Pelican case. The camera lens was about 0.55 inches in diameter, and fits into the hole with very little clearance. I have more notes on the specifics of the case modification over at RaspberryPi/Weatherproof Camera Case. This is Stage 1 of the Pelican modifications. Eventually this will be full-on waterproof, but the goal for Timelapse 4 was to keep it simple, stupid.
Upgrading Image Software
I needed to upgrade the way I was grabbing images from the camera. I decided to bite the bullet and go with SimpleCV, which would provide access to more high-power image processing applications - exactly what I'm looking for.
Installing SimpleCV
To install SimpleCV on the Raspberry Pi, you will need to install scipy, and that's gonna take a while:
$ sudo apt-get install python-scipy
(Note: I don't recommend doing pip install scipy, as that does not install the proper linear algebra headers, and now you're going to spend your evening in Dependency Hell.)
