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.
