monic part 3: towards a handheld

[Chr Yoko]

Very nice project !
Your chosen microcontroller looks very powerfull , why such choice instead of a 32bits Arduino such as a STM32 base ?

Hereby EEVblog that is showing how to get made a custom membrane keyboard :

From here :

(exemple @ about US$255 for 4 parts, with embossed keys , their stainless domes and 4 colors on the overlay)



OK, bit expensive and not as good as a real keyboard, but has a professionnal look to it.

Also I would be interrested by the software side of your project ;-)
