Summary

Bare bones night vision camera using a Raspberry pi zero with noir camera V1/V2, a IR Infrared 36 Led ring, tripod attachment, HC-SR501 motion sensor, LM2596 DC to DC Buck Converter as a power supply for the raspberry pi zero and a 12V AA battery holder with switch.

I made this as quick and dirty frame to hold a raspberry pi zero with noir camera to act as a camera trap. I have also uploaded a version without the motion sensor in case you want to use camera based motion detection such as motionEyeOS https://github.com/ccrisan/motioneyeos

I kind of threw this on thingiverse in case anyone found it useful. Personally I'm done with this design and have disassembled the version I built.

Basically the battery goes in the groove on the base. The camera attaches to the the ir-led ring via the adaptor. The ir-ring screws into the large hole. The motion sensor goes into the smaller hole above the leds. Then there are mounting holes beneath the led ring for a raspberry pi zero, the 5 volt regulator and a small pcb for additional electronics such as a transistor to control when the leds are switched on by the pi.
