A 3D Printed “Cootie” Key for CW/Morse Code #3dThursday #3Dprinting
WiskeyTangoHotel builds a Morse Code “Cootie” key using a 3D printed base and handle.
CW or Morse Code is a way ham radio operators send messages with a simple tone of two durations. It was a must before the days of wireless voice communications and still remains popular because it is a fun challenge. Also, due to its efficiency messages can get through with limited power or in poor conditions.
There are no shortage of morse code key designs, but in general they fall into a few categories that are discussed here. We decided to DIY a “cootie” or “sideswiper” key and used our 3D printer to produce this design from Thingiverse.
The result was surprisingly fantastic in both look and feel. Now, to practice.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
