Hello Bruce W8BH,
That is very educational. Nice work.
I am looking forward to the microcontroller part.

Attached are photos of a Morse Tutor prototype I built. Some features:
Handheld: 110 x 60 x 20 mm (roughly)
Li-poly battery or USB powered, with built-in battery charger
Larger 3.2" display.
Built-in speaker + External audio out jack
Runs the same code-base at the Blue Pill.
The construction is mainly SMD. The "enclosure" is a PCB sandwich.
It is a work in progress so I don't have many details. But if anyone wants a great way NOT to make a power supply, I can help.
