Baby Spectrum

This is the case of my portable tiny ZX Spectrum 48K (emulator) using a Wemos Mini :)

Has a fully functional 40-key qwerty keyboard just like the real one, so it's fully programmable just like the real one too, as well as run virtually any game made for the original; the built-in kempston joystick also helps. :)

Update:
Added two new, retro 80s TV set style screen covers, one for 2.8" display, the other for 3.2". Note that they are rotated 180 degrees compared to the old display case, but i also have it flipped in the latest version of the software.
