Amélie (2023)
↗
Amélie is an open-source selfie printer that uses a Raspberry Pi and a thermal receipt printer to produce instant photos on fade-able paper.
It shows how inexpensive, off-the-shelf parts can be combined to create an interactive photo booth without ink. Engineers can view the project as a reference design for low-cost, temporary imaging systems that balance immediacy with limited longevity.

Images are formed on thermal paper that darkens when heated and then fades to white over time.
Version 3 runs on a Raspberry Pi 4 with a Camera Module V3, a LED-ring button, and a transparent plexiglass enclosure that reveals the internal modules.
Earlier versions (v1 and v2) used a Raspberry Pi 3 B+, a smaller camera, and were housed in a wall-taped or shoebox setup with optional USB storage and config-file adjustments.

The move from the first two iterations to version 3 introduced several hardware upgrades.
The main computer changed from a Raspberry Pi 3 B+ to a Raspberry Pi 4, providing more processing power.
The camera was swapped from the older V2 module to the newer V3 module, which adds autofocus, faster live preview and better exposure measurement.
