Micro LED Matrix

So I was looking for a distraction when I was stuck on a project last week, and decided to throw together a variant of the "64 pixels are enough" project by Alex at Tinkerlog...

I really did nothing with his code besides change up some of the sayings. Differences hardware-wise are a smaller LED matrix I had from Seeedstudio's store and the use of a CR2032 coin cell for power. It seems to run for about 2 days on that vs. the 2 weeks Alex gets from 2xAA cells, but it's more compact. Some of the folks interested in wearable items may find it of interest.

I'm happy with how it turned out, and have a video below. Apologies for the poor quality, done with a phone camera, and it seems an interaction between the refresh rate of the camera and that of the the device caused double frames to show in much of the video.

  1. Neat Joe - Chris A here. How do you go about creating a logic board for something like that?
