Flip-Dot Sign Generator

Flip-dot signs โ€” buses, old stadiums, hacker spaces โ€” have a fizzier, more electronic personality than full split-flap boards. FlipLetters simulates the dots directly, so anything you type becomes dot-matrix lettering.

TL;DR

Text typed into the Flip-Dot board is rasterized into an 84ร—28 dot matrix โ€” white dots flipping on black with a fizzy click, like a bus destination sign. It also accepts painted dot grids and imported images, at densities up to 168 columns.

How it works

  1. 01Open the Flip-Dot board and type your message.
  2. 02Pick a density preset (low retro to high resolution) and the fizz sound.
  3. 03Export, or switch to paint mode and draw the dots yourself.

Questions

Can it show images?

Yes โ€” import an image and it's rasterized to dots; simple, high-contrast art reads best on the dot grid.
