From the project
Two Types of Touch Keyers (Paddles) for CW (Morse Code), Tested on the QMX+
Implemented for use with the QMX+ HF transceiver. PCBs designed in KiCAD v9.
The first keyer is a capacitive touch keyer, based on "Penny Paddles", https://www.thingiverse.com/thing:7049323.
The second keyer is a pressure paddle, based on https://vk3il.net/pressure-paddle-v2/.
The capacitive touch paddle is based on KD9AIE's Penny Paddles schematic. It has been slightly modified:
