On my quest for a better understanding of the hardware involved with learning CW, I started finding come cool homebrew keys. The one that really stuck out for me was The Hackey. It not only shows how simple a key can be, but it’s made from found stuff. Perfect!
The center post/screw is the common ground and the 2 halves of the hacksaw blade are the contacts. The long screws toward the front adjust the distance of action and the screws in the back just hold the contacts in place and connect the dit and dah wires.
This is a simple, fun and satisfying afternoon project.
