Beam: A simple LED matrix for notifications

Hey everyone,

We wanted to share something we built. Meet Beam:

It’s a 120 LED grid (5x20) that lets you scroll text, create animations, or simply use it as a basic display. We wanted to build long LED matrices and using multiple 8x8 matrices was quite painful. We wanted to simplify that and so we built Beam.

Using it with Photon + IFTTT makes it quite powerful!

A few examples:
Bus schedule updates:
Notification center:

Some of the main features:

  • Easily chainable. You can attach up to 4 Beams in a row and make a super long display. Beam has 90 degree headers so that you can easily chain them together – no soldering required.
  • Simple library. We designed it so that you can do something like beam.print(“hello world”) and it would show up right away. We’re finalizing the library for Photon and will post it asap.

Let us know what you think!
