The Code Buddy was a Morse
Code practice oscillator that we use to make from
1996 to 2002. It actually appeared as a simple
construction project in the July 1996 issue of Nuts
& Volts magazine! We present the schematic here
for those who would like to use this diagram to
make their own. It is quite simple and easy to
make. A perf board can be used to wire it up.
Enjoy!
