The 30mm pixels from Ray Wu at AliExpress arrived today!!! Now we can start ont the new Merry Christmas sign. Of course, first things first. Lets test them and make sure they work and see what we have gotten ourselves in to. Below is the first test. I created the letter "M" on a sheet of white coro and a sheet of black coro. Which one do YOU think looks better and why?
