Little circuit of a Morse Code Oscillator is presented here. Excellent for learning and teaching Morse code, this code practice oscillator – ideal solution to practice sending the code and improve ...

This project illustrates a working homemade Morse code oscillator that is constructed in an Altoids can while the paddles are constructed using copper board, eyeglass screwdriver, and rubber bumpons.

Morse code enthusiasts can be picky about their paddles. After all, they are the interface between the man and the machine, and experienced telegraphers can recognize each other by their “hands”. So ...
