RaspberryPi/Timelapse3
From charlesreid1
Third Timelapse
Timelapse number 3: accomplish a few improvements in the timelapse process.
What's working:
- The camera is working and is able to capture images. There was a problem initially, but after trying to re-enable the camera several times, and rebooting several times, the camera started working.
- The script to dump images into a directory works great in concept. Easy to keep everything segregated.
What to do differently for this timelapse:
- 64 gb thumbdrive for space
- camera angles - better control mechanism
- case: improved housing for Pi and for Pi camera (integrated?)
Ideas In Progress
Weatherproof Case
To make my own weatherproof case: rather than designing a 3D printed case with the proper knobs and buttons and things for USB and etc., get a larger plastic weatherproof case. Obtain the proper screws, washers, o-rings, etc. to mount the Raspberry Pi into the case, then obtain the proper glass disks, screws, washers, o-rings, etc. to mount the Pi camera on the inside of the case.
Easy start, because we can drill holes in it.
How to mount hte camera?
- Does the O-ring rest directly on the camera? If so, there is not much field of vision and the size has to be matched perfectly with the camera. If not, the camera protrudes at least 1/8 of an inch, so you'd need a really fat o-ring, and one that wouldn't compress too much, and that just seems like a bad design.
- Does the glass disk rest directly on the camera? If so, would that affect field of vision? If not, what configuration?
- I think the glass disk rests directly on the camera.
Additional tripod mount screw hole would have to be added to the case - but again, much easier to do that with a larger case, than with a fitted-perfectly-for-the-Pi case.
Additional hole and rubber gasket for power cord would have to be added to the case.
Materials:
- Weatherproof plastic enclosure/case (tuperware? art supply case? Visit the hardware store.)
- Pi-to-case screws: 4-40 thread, 3/16", x4
- Camera-to-case screws: M2 size, 5 MM, x 4
- Camera-to-case seal: M 1.6 size, 4 mm (x4 for seal)
- O ring, 13 mm ID, 1.5 mm, for seal
- Glass lens: 17.9 mm x 1.2 mm
- Specifically look for PCB mounts/fasteners. Examples here: http://catalog.pemnet.com/category/fasteners-for-mounting-into-printed-circuit-boards
Attache Case
Mount camera to inside of attache case, can add foam mounting, 1-2 Raspberry Pis, wireless cards, radio antennas
Add physical controls: aggressive/attack mode, defensive/listening mode, etc.
