This is a small Raspberry Pi with a battery pack that I've tied to a cat collar.
It's fairly light but much too bukly. It's impossible to see anything when the cats move.
The Pi saves video to its memory card, which I then transfer over to my desktop over wifi. The battery is strong enough to keep going for hours and hours.
- A Raspberry Pi Zero 2 W
- A Pi Camera
- An official Pi Zero case with the camera cover
- A 4,000 mAh battery pack
- Velcro straps or zip-ties to bind the setup on a cat collar.
I was curious to see whether stabilization could recover the overly shaky footage, but it turns out that it doesn't really. I think stabilization is better for removing slight shaking. This is too extreme.

Desoldering a Pi
I had been using my Pi Zero for my plants. I had to get rid of the GPIO pins so that the board can fit in the case.
