## What it is
An open-source DIY split-flap display project based on ESP32, including mechanical designs (OpenSCAD), electronics (KiCad), and firmware (Arduino/PlatformIO). It is optimized for easy home assembly in small quantities while scaling to large multi-module displays.

## Use cases
- build a diy split-flap display at home
- make a retro airport departure board
- create a large mechanical letter display
- laser cut and 3d print a splitflap module
- control a split-flap display over wifi with esp32
- learn open-source hardware design with kicad and openscad

## When to choose
- you want a proven, community-supported open-source hardware design with stable releases
- you need a display scalable from a single module to 100+ modules
- you want complete mechanical, electronic, and firmware files in one project

## When to avoid
- you need a plug-and-play commercial product with no assembly
- you have no access to laser cutting or 3D printing for the mechanical parts
- you need a software-only simulation of a split-flap display

## Facets
- artifact type: application
- maturity: active
- function: embedded, graphics, developer-tools, documentation
- domain: hardware, embedded-systems, cross-platform
- platform: embedded, iot, cross-platform
- tags: split-flap-display, diy-hardware, openscad, kicad, laser-cutting, esp32, 3d-printing, maker, automation
