I've rebuilt keyboards before. Liking/wanting thin and split keyboards necessitates doing that, there are none ready to buy. Lately I've wondered about minimizing the number of keys as well. Suddenly I got the urge to try it out, and that lead to a new experimental PZ1-keyboard!

It communicates via standard serial, not USB or PS/2 connection. This makes it a LOT less bothersome to receive data from :)

Now I only have to figure out a good way to make some keycaps or overlay. It is definitely much smaller than the real keyboard I've used so far. We'll just see which I prefer down the line.
