In this video I build a fun “breathing” LED sign using IC Station’s “Breathing Lamp Kits” (see link below). Here I’m building a friend’s Ham radio callsign, but you could use these kits to build all sorts of signs. The case that I used will handle up to six letters/numbers. Of course, you might have your own ideas for how to mount these boards. It took me about 6 hours to assemble this sign.
