WW9JD Arduino uMatic Memory Keyer

Update to the classic early 80s Heathkit keyer. I started this project learning PCBARTIST from Advanced Circuits, but they wanted $170. I cancelled, learned kicad (well enoigh), ordered my boards for $25 after a $5 coupon (shipping included from both fabricators), and received my boards from China faster than Advanced Circuits could refund my purchase payment.
