I do a lot of projection installations, in unique locations, usually with about zero setup time. When I looked into buying a professional 10’x7’ “fast-fold” screen, I was blown away by how much they cost. Instead, I decided to design my own, using easy to find materials. The Challenge: 1. Fast to set-up 2. Fits in a cab 3.
Alex took his original idea of the programmable LED and made it even cooler. He took 25 of his LED’s and put them together on 1 board. Each LED reacts to the others.
One of the first lessons that an electronics student learns is that an LED provides light from current flow. But, did you know that an LED put in backwards provides current flow from light? Yes! It’s true.
