Code Practice Oscillator
I decided to make a CW practice board for Morse Code training for my local HAM club. I have donated all 10 boards to the club. It was a simple process to use KiCad 7.0 to design the board.
I am not going to explain how to use KiCad in this wiki page since I have other wiki pages explaining how to use KiCad. This project uses a NE555 timer SMD SOIC-8 Chip that produces a square wave that can be adjusted between 300Hz and 1KHz
RV4 is a 200K ohm variable resistor that control the tone between 300Hz to 1KHz. It is made to be adjustable for the user to change to the tone they prefer. RV3 is a 100 Ohm variable resistor that controls the volume.
The CW key is connected to a Terminal block that is label CW Key
