Splitflap: An Open-source, 3D Printed, Arduino-based Split-Flap Display System
Splitflap is an intriguing GitHub project, championing the blend of software and hardware by providing an accessible, open-source split-flap display system powered by Arduino and
3D-printed elements. The project is significant as it revives the charm of the old-fashioned split-flap displays in our modern digitized era, through an innovative and inclusive route.
Project Overview:
The primary goal of Splitflap is to enable the creation of split-flap displays using commonly available, affordable components. This DIY project addresses the need to preserve the aesthetic of retro split-flap displays, often seen in train stations or analog clocks. It aims to bring this experience to DIYers, hardware enthusiasts, and Maker Faire participants who are thrilled by the marriage of coding, mechanical engineering, and nostalgia.
Project Features:
Splitflap stands out with its array of brilliant features. Key among them are the comprehensive build instructions, including a list of the 3D-printed parts, electronic components, assembly guide, and a link to Arduino code. These elements combine to create a charming, retro-tech display that can be easily customized - from displaying simple messages to a kitchen timer function. The integration of clear instructions with an accessible hardware-software interface is what sets this project on a high pedestal.
Technology Stack:
This project heavily relies on Arduino Uno, an open-source microcontroller board, for controlling the display. Primarily programmed in C++, the simplicity and efficiency of the Arduino language allows platform-independence thus crafting a broader user base. The physical parts of the display are 3D printed using easily available material, demystifying the fabrication process. In terms of software, Python scripts are used for tasks like generating the SVG files required for laser cutting.
Project Structure and Architecture:
Splitflap’s structure is a fine blend of hardware and software components working seamlessly together. The key hardware components are an Arduino microcontroller and the 3D printed mechanical parts including flaps, motors, sensors, and frame. On the software side is the Arduino code that drives the microcontroller, and the Python scripts used in designing the display. Even in its simplicity, its architecture exemplifies a well-coordinated IoT device.
