Your New Favorite Camera Is a Raspberry Pi

Backlash against smartphone photography has entered the mainstream. Store shelves are now stocked with dedicated digital cameras inspired by classic designs. Beyond offering a refreshing alternative to the familiar black slab of a phone, these cameras also shift the mindset away from disposable, rapid-fire photography. Rather than taking dozens of shots in the hope that one turns out well, they encourage a slower approach where each photo is taken with purpose.

This trend has also hit the maker scene in a big way in recent years. The latest example of a dedicated DIY camera comes to us from Doruk Kumkumoğlu. Called Optocam Zero, it was built entirely from off-the-shelf components and 3D-printed parts. Inspired by the KODAK Charmera keychain camera, it is meant to be fun, portable, and enjoyable to use. It also takes some pretty nice pictures for a homebrew camera.

Optocam Zero is powered by a Raspberry Pi Zero, transforming a tiny single-board computer into a fully functional digital camera. The device emphasizes simplicity and accessibility, both in how it’s used and how it’s built. Kumkumoğlu has released a complete set of resources — including a bill of materials, CAD files, and a detailed build guide — making it possible for hobbyists to recreate or customize the camera themselves.

The device uses an autofocus camera module capable of capturing square 2592×2592-pixel JPEG images, while maintaining a smooth live preview at 15 to 20 frames per second on its 1.4-inch, 240×240 display. Image processing happens in the background, allowing users to continue framing their next shot without interruption.

Controls are designed to be intuitive, reinforcing the idea that photography should be simple and fun. Eight built-in photo filters add a creative touch that brings to mind the aesthetic experimentation that made early digital cameras so engaging.

Power comes from a replaceable 14500 lithium-ion battery, providing roughly 70 to 80 minutes of use per charge. USB-C charging adds convenience, and the camera can operate while plugged in. The entire unit measures just 51×71×18 millimeters, making it comfortably pocketable.

Optocam Zero has a fully 3D-printed enclosure. Builders can print the case themselves, experiment with materials like PETG or carbon fiber blends, and add optional accessories such as a TPU protective sleeve or lanyard.
