Camera module with auto IR filter cut

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 print the nuts and balls as much as you need.

A little side note, i changed the z-axis leadscrews (8mm lead to 4 mm lead) on my ender 5 and didn't cut them at the right length yet, that's why the leadscrew is in front of the cam view. Sorry for that.

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.

You can ofcourse flip the horizontal and vertical in octoprint but, if you record your camera motions in synology surveillance station like i do, then flipping the image in octoprint won't affect the image outside octoprint.
