This is pretty interesting, but it'd be great if the author explained their reason for building such a large keyboard... even if it's just "for reasons".
this was also posted on r/MechanicalKeyboards and the reason behind it was something like “I made a 128 keys keyboard, someone else made a bigger keyboard so I had to retaliate”
That's exactly why I made Ginny (the small red keyboard in OP)! It's an exercise in insanity, but it does work as a fully functional keyboard powered by ASETNOIP. I could never daily it (too attached to my 36key GergoPlex) but some users are above 130WPM on 10keys!
