Diffuji is a diffusion powered instant camera made in 36 hours at Treehacks 2026.
Built with a raspberry pi zero 2w, a thermal printer, and a small camera housed in a custom case, Diffuji snaps a picture, filters it using AI, and prints it out immediately.

The Case
I designed the camera case in Fusion360 and 3D printed it at Stanford’s Product Realization Lab.
The case is designed in two parts that can be printed with no supports. After printing, the two halves of the case are screwed together.
Features:
- Grip to capture the charm of retro Kodak instant cameras
- Mounting shelves to securely mount the battery pack to the case
- Openings for the USB port, LCD screen, shutter button, dial, and power switch
- Open back to easily slide in and secure the thermal printer
