The Morse Machine - for Morse code demonstration, learning and practice

thingiverse

Morse code remains an enthralling phenomenon that continues to captivate people of all ages. This entry outlines a setup designed for practicing and demonstrating Morse code, with the intention of making it both easy and affordable to build using 3D printed components and widely available parts. The Morse Machine can be constructed with either a straight key or paddles, as seen in the accompanying images. While this device can undoubtedly be used for transmitting signals through a transmitter, its primary purpose has been to teach and demonstrate Morse code, particularly to promote amateur radio. A detailed schematic, comprehensive assembly instructions, and OpenSCAD source code are provided below for the electronics component of the Morse Machine and its cabinet. These instructions also include links to the firmware and 3D printable Morse key designs. The most recent iteration of this design is available on GitHub at https://github.com/tskauli/MorseMachine. The paddles can be found on Thingiverse here: https://www.thingiverse.com/thing:3168497. For those who prefer a manual key, it can be located on Thingiverse here: https://www.thingiverse.com/thing:3167343. The Arduino Firmware has been modified from the widely popular K3NG keyer software and resides on GitHub at this location: https://github.com/tskauli/Morse-Machine-K3NG-keyer.
