I’m prepping to do a 1024 LED sculpture, and the suggestion came up of scaling it from 2′ x 2′ to 4′ x 4′. I was concerned that this new size without an equivalent increase in LEDs (which I really am not prepared to do) so I built a sample square foot panel to try the spacing. Of course, I don’t have a square foot protoboard (does anyone?) so instead I built it on a piece of cork board. What I really liked about this method was that it allowed me to prototype it as a 2 layer board.

The larger scale actually works a lot better than I anticipated.
