What this is
This is an experimental side-project I did. It's a stick with a bunch of individually-addressable LEDs, with a microcontroller. You load an image onto it, drag it from left to right while taking a long exposure, and it displays the image in the end result.
Why I needed it
I didn't! It's just a fun idea.
How I made it
It took a while! I had a few unstarts, too. More details can be found in the build log!
These are also in the build log!
