Beautifully documented, modular, and completely open-source, this split flap display project by [JON-A-TRON] uses 3D printing, laser cutting and engraving, and parts anyone can find online to make a device that looks as sharp as it is brilliantly designed. Also, it appears to be a commentary on our modern culture since this beautifully engineered, highly complex device is limited to communicating via three-letter combos and cat pictures (or cat video, if you hold the button down!) As [JON-A-TRON] puts it, “Why use high-resolution, multi-functional devices when you can get back to your industrial revolution roots?” Video is embedded below.
The only limitation is that the device has no way of knowing the state of individual displays, so it’s unable to spell out specific messages – an operator simply holds a button to scroll through letters, and stops when the correct letter is displayed. For a similar project that has serious control hardware (but none of the cheeky commentary) check out this scratch-built alphanumeric split flap display.
