Article summary

The article describes a project to build a large interactive wall art using flipdiscs, a display type that utilizes electromagnetic pulses to flip small discs between two colors. The author chose flipdiscs for their high readability, long lifespan, and unique sound. The project involved designing and building a custom board, powering the display, and creating software to control the flipdiscs. The author also developed a library for using flipdisc screens in Node.js and created various visualizations for the display.

What commenters say

  • The cost of flipdiscs is prohibitively expensive, with prices ranging from $3-5 per pixel, making them inaccessible to hobbyists.
  • The mechanical nature of flipdiscs makes them more satisfying to watch and easier to read than modern LED or LCD displays.
  • The replacement of flipdisc displays with LED or LCD panels in public spaces is likely due to the lower maintenance costs and increased reliability of the newer technology.
  • The unique characteristics of flipdiscs make them well-suited for certain types of visualizations, such as low-frame-rate animations or text displays.
  • The sound produced by flipdiscs is a significant part of their appeal, and could potentially be used to create music or other audio effects.
  • The development of custom hardware and software for flipdiscs is necessary to fully utilize their potential and make them more accessible to a wider range of users.
