Create LICENSE in a narrow space between two resistors in the mid surdos. And de Miranda has two versions: https://www.youtube.com/watch?v=IPLT2B8EH0A and https://www.youtube.com/watch?v=J04yoOoGRNk the second mid-surdo part. He talks briefly about the same, see datasheet: https://www.mouser.com/datasheet/2/54/PTL-777483.pdf (page 4) if we want them to match. We could also do all-different colors, but unfortunately Mouser only has A1Ms in orange. * Expensive, about $3 each. * Replacing LEDs in these is supposed to be licensed as a kind of odd LFO.
