Building a single-panel JUMBOTRON using HACKERBOXES 0036

This month’s Hackerbox #0036 I found very interesting. In the box was a single RGB LED Matrix with 64×32 pixels! It’s one of the panels that is used for making those massive retro arcade classics that you see at Dave & Busters, Stars and Strikes, etc. I’ve always wanted to see what these panels look like and work with one, Hackerbox delivered! Let’s check it out!
