Edgar implemented capacitive touch sensing using an ATTiny4 to create a touch paddle for Morse code: Like many no-code operators, after being on the air for a while, I developed an interest and appreciation for Morse Code [..] I purchased a cheap paddle, but I found the clicking noise a little bit annoying.
