@kenneth C2 is a standard 0.01uF ceramic capacitor. They’re about 30 cents and you’d probably want to get want that handles a max of 25V.

Thanks for the plans btw. I’m planning on building this, but I will be adding some potentiometers for pitch and volume.

Awesome project. I’m looking forward to seeing this one. I haven’t taken up CW yet, but it is on my list. When I do, I plan on doing a mouse-keyer.

Great idea.
