Minor rant: You can't send morse code by tapping random objects, dammit.

Morse uses beeps of different lengths. If you can't send a dit that is distinct from a dah, it just isn't going to work. For example, R is di-dah-di. It might be tempting to think you could fudge that as tap-tap-(pause)-tap, but that doesn't work. You just sent 'ie' (di-di di) instead. Spacing is used to denote letter, word and sentence boundaries only. You might as well try to speak English without any consonants.

I know it's a very convenient plot tool to have people communicating between locked rooms by hitting a pipe with a wrench. But the only message they can send is "I'm hitting a pipe with a wrench!" Please, find a better solution.

I always figured it was a matter of timing. If you have good timing, you set a beat and then apply half-steps for the long beat, normal beats for the short. Just like over telegraph lines.

Of course, if you have lousy timing, you'll never figure out which are the long and which are the short, which is why some people can do it and others can't.
