The code is set to take a photo every 5 seconds, but you can easily increase that value to take longer intervals. On line 24, you can change the value from 5000 (milliseconds) to whatever you want (too short of a value and it may not work).
Mounting to Tripods
The case doesn't have a built in way to mount it to a tripod, so I created a little 3D printed adapter that can connect to GoPro mounting accessories. It's a little "knuckle" that can be glued on the back side of the enclosure. Since I a lot of GoPro mounting bits, I thought I'd reuse them. This 1/4-20 GoPro adapter lets me easily mount it to any tripod. In this project, I'm using the standard GoPro tripod mount.
Creating Video Timelapses from Photos
The camera module simply takes photos and saves them to the microSD card. It can not generate a video from the image sequences, so you'll have to do that in a video editing software (or a website if such exists). I personally use Adobe Premiere, but you can use whatever you have access to. I won't cover it in this tutorial, but I'm sure there are other resources that can help you there.
Todd Treece mounted the camera to his husky/malamute k9 friends using a hardness and GoPro adapter. Fun idea to capture your walks :-)
The 100mAh lipo battery will power the circuit for about an hour. I know it's not a lot of time, but was suffice for me. I was able to capture 15 second timelapses using a 5 second interval. You could obviously add a bigger battery for longer time lapses, but that would require a bigger case. My main goal was to keep it small and make the smallest enclosure I possibly could. That's why I added a lipo backpack to the circuit so I could at least recharge the battery easily.
