Motion Activated Camera Trap Trigger

Capture wildlife or unsuspecting visitors with your DSLR using this PIR-based camera trigger. https://diyodemag.com/projects/camera_trap We created an enclosure in Fusion360 and will share the working files so you can modify the design as needed. To mount the camera, we chose the GoPro system because it has numerous official options and custom styles available on Thingiverse to suit different needs. If you want a custom mount, simply search for "GoPro mount" on Thingiverse and find a wide range of custom mounting options that save time designing and modeling your own. We wanted the device to attach directly to the camera, so before designing the hotshoe mount, we searched for it on Thingiverse and found that user Shantmeg had already designed the exact part (https://www.thingiverse.com/thing:98700). Therefore, we didn't need to create our own design. The front part of the enclosure was printed at 300-microns on our Flashforge Creator Pro using translucent red PLA. The design requires support under the mounting bracket and switch housing, taking around 1 hour to print. Note that the hole for the lead to exit the enclosure is 3mm in diameter. You may want to increase this depending on the wire you use, which can be done using the working files or by importing the STL file into Tinkercad and making the modification there. The rear of the case was printed at the same 300-micron layer height on our Flashforge Creator Pro, also using translucent red PLA. It takes around 30 minutes to print without support material. The enclosure simply presses together after all components have been installed. The GoPro type hot shoe mount (Credit to Shantmeg on Thingiverse) has a small raft and supports included. Our print was made at 100-micron layer height on our Flashforge Creator Pro in translucent red PLA, taking about 45 minutes to print in this orientation.
