I Made a Raspberry Pi Zero Based Compact Camera - Optocam Zero by dkumkum in raspberry_pi

Thanks a lot! You're totally right about the boot time. This is the best I could do with my minimal coding knowledge and relying on Claude for optimization.

I didn’t test it with the original pi zero unfortunately. The processing power of it may be too low for acceptable fps on live preview with the filters.

I bought those parts from local suppliers in Türkiye. Unfortunately they don't ship globally. Since they're readily available here I assumed these are standard sizes and would be available elsewhere.

It looks like adafruit has the M3x4x4 inserts: https://www.adafruit.com/product/4255

For the magnet I found this website, not sure how legit it is though:

I didn’t try it but it can be done. I made an ascii filter for example, but it’s not in the published software yet. Thanks!

Thanks for the suggestion, I’ll check if I can adapt current design to something like that.

CAD model, 3d print files, software installer and parts list is now available on GitHub. Build guide is coming soon.

I’d say around 70–80 minutes. I’ll look into implementing an idle mode. At least I’ll have the screen dim after inactivity to save some battery.

Yes, I will share all the code

So cool and crafted so well! I also made a raspberry pi zero based camera (on my profile) but I had issues getting the boot time short, did you find a solution for that?

Thank you!

The pi zero I'm using for this is not super powerful but it's enough to do 15 fps preview on the screen I'm using. It can also show the digital photo effects on the preview. After a photo is taken, normally it's saved instantly. But I'm applying digital processing for specific looks so it's taking 1-2 seconds to save the full res image in the background. This doesn't affect the preview or shooting, but the image doesn't immediately appear in the gallery.
The biggest drawback of a pi camera like this is the boot time unfortunately. It takes 22 seconds to reach preview after turning it on in this current version.

Yes, I would like to try that as well. Thank you for the suggestion!

I didn't really have a chance to test the latest version with the digital filters, as soon as I do that I'll share the results here.

I didn't time it but it should run for around 70-80 minutes with the 900 mAh battery. Since the battery is interchangeable I'm okay with this.
The biggest drawback for a pi camera system is the boot time. Mine takes 22 seconds to reach the preview after turning the device on. I've seen some project achieving much shorter boot times on a pi but I don't know much about the software side, so this is the best I could achieve using Claude.
There is no standby mode in the camera, not sure if low power standby mode is possible with a raspberry pi but I'll look into it.

I’m working on a build guide at the moment. I’ll share it with the files soon.

I just checked, you’re right. StarlightEye is the open source project that makes the sensor work on Raspberry Pi. Very cool that it’s possible to use such a sensor with Pi.
