Reinterpreted Commodore C64

I love the design of that classic computer... and I love the idea to add special chars on the front of the keycaps.

I used an old C64 as bluetooth keyboard, but... I love small keyboards, too! So, because I can add a nrf24 chip to an arduino 32u4 and a second one to a mega328p, I build my own cool small mini c64 wireless keyboard! But known bugs: pressing shift+Fn or +Alt or +Ctrl could not be identified in my code. DIY and make it better than me!

I do not publish everything here... feel free to build your very own simple c64 design interpretation!

PS: the zip file has 2 arduino projects but it uses some additional libs and wire/circuit instruction is missing. I add my .Xmodmap for e.g. alt+gr+; to get ö and a windows setup to get the same keymap. I love the US layout for programming... but sometimes you need the 4 german special keys.
