<p>This is a simple, minimal hardware, side swiper Morse code key. Otherwise known as a "cootie" key.</p> <p>NOTE: You will want to print the arm on a raft to prevent the leaf spring parts from warping off the bed.</p> <p>This design only needs five screws, two nuts and one thin washer for assembly. Small solid copper wire will slide through the channels for a cleaner looking result. The printed PLA leaf springs work very well for returning to center. Operation is quite smooth.</p> Category: Electronics
