This project makes a great little key, but how much harder is it to make a paddle key? One that has dit and dah depending on which side you press. If you hold one side down all you hear is dits and if you hold the other side down all you hear is dahs.
How hard is it to make something like that?
Thanks

how about using a 556 timer set up as 2 different sounding oscillators ?
1 trigger going to each side of the paddle ?
