Show HN: I made a tiny camera with super long battery life

#1
Hey HN!

A few years ago someone kept trying to steal my motorcycle, so I decided to make a small camera with really long battery life to catch them.

The hardware/software is totally open source, but the companion app only supports macOS currently. (I'm a big fan of native apps, and didn't want to block releasing on Linux/Windows support.)

I wrote some blog posts about the process:

very cool, love the website design and the blog posts had a lot of interesting bits, like the backplate removal jig. I was kinda surprised to see an fpga in there but makes sense. Could that design be repurposed as a general image sensor -> sd card module or is it pretty specific to the sensor?

Cool project, here's a few comments after a quick glance over:

- There's no license on the code and design files in the Github repo, thus this currently isn't open source but rather "source-available". If you plan to allow others to modify the code and build their own cameras you should add an appropriate license.

- The Mac only support (and it's MacOS only, with no iPad/iPhone support) with a dedicated app to operate it seems to really limit the market for this device. Since all the app does is allow you to view/transfer photos and configure the device you probably could make do with a simple MTP interface for access to the photo files and have a second interface for configuration. Also if you do plan to release this under an OSS license and market it as a hackable + privacy friendly device Linux support is pretty much a requirement.

- Consider using automotive grade ICs to allow the device to function below freezing. The current stuff may be fine for Cali but people in northern states won't be able to use it outdoors in the winter.

so cool!

For your next trick, how about a super long battery life MP3 player? A friend asked if I knew of an MP3 player that would be good for a two-week hike with no access to electricity, and it really seems like there's nothing out there beyond carrying around a bunch of batteries.

The camera seems really cool. But given that the device has no way to get photos off it without physical access, it seems like this wouldn't be super useful for your original purpose. If someone just takes the camera (or manages to successfully steal your motorcycle), then then camera doesn't provide any value.
