Did the scouts Morse code activity yesterday, and I think it went pretty well. For the hands-on challenge part of the meeting, each patrol had a lock box with prizes inside, and to find out the combination to the lock they had to decipher three clues that were given to them in morse code.
For this part, I Claude-slopped together a small static page that was preloaded on an iPad that we gave to each patrol. Here's the one we gave to the Alpha patrol:

The takeaway is that some kids have real trouble telling all-dashes letters from all-dots letters (such as O/--- and S/...) when they don't see/hear them next to each other. This was surprising to me, because I've never really expected anyone to have any trouble with telling those apart, but then I've always had a musical ear.
Sharing this with others in case you want to run a similar activity and want to reuse my idea. Since the app was slopped together, it's in the public domain and you can use any number of online ROT13 translation sites to encode your own messages.
