Pi auto IR cut camera case 3d printer

Last crawled date: 4 years, 2 months ago

Hi,
I made this pi camera case because there wasn't any case that would fit a raspberry pi cam with the auto IR cut filter. This camera is more usefull then others because with the auto IR cut you don't have a pink picture at daylight.
The case fits perfectly, it also has place for 3 heat sinks (14.2mmx14.2mm heatsinks) , the cam and the IR lights can now easily loose their warmth.
All the parts will set you back 19 dollars/euro. (except for the t-slot nuts, but you should have them at stock anyway for all kinds of mods)
To mount the camera i made a straight and a 90 degree camera mount and a 2020 profile mount. To extend it i used https://www.thingiverse.com/thing:1079807 his nuts and balls. Print as much as you need.
A little side note, i changed the z-axis leadscrews (8mm lead to 4 mm lead) and didn't cut them at the right length yet, that's why the leadscrew is in front of the cam view.
Settings,
You need to edit octopi.txt, search for the line #camera="raspi" and change the source to "raspi" instead of "auto" or "usb". Also remove the # before the line.
Then for the cam settings scroll down to: "Additional options to supply to MJPG Streamer for the RasPi Cam" and add the folowing line.
camera_raspi_options="-x 1280 -y 1024 -fps 20 -quality 15 -hf -vf"
these settings seem to work best and gives the right FOV and screen ratio.
As you can see i have set a low (15) quality, i did this because i saw no difference between a high and a low quality setting, only thing that did changed was the bitrate that would go skyhigh, so i leave it at 15 for now.
Also i added -hf and -vf to my settings, it stands for vertical flip and horizontal flip. I did this because i have the cam upside down.
