I mean, sure, this is pretty neat, but par for the course with the excellent projects posted every day at sites like deskthority.net and geekhack.org. I'm surprised this one made the front page. It's neat but not the first of its kind.

There are folks on these sites who are re-creating IBM capacitive buckling spring keyboards "from scratch": new molds for all the components. Also, keyboard.io is a keyboard project complete from scratch (except for the switches) from some friends.

Kudos to the OP for building a keyboard! It's great fun and very instructive. Head to the forums I linked above if you'd like to see more.
