Nice job, Doug. I have a K3NG keyer that I built using an Arduino Nano. I power mine using the USB, which also allows it to be controlled by programs on the PC, such as N1MM contesting software. Unfortunately, because the Nano doesn't have much memory, I can't use all the features. I've been thinking of doing another version using a Mega. I'd also like to put a display on mine.
