Man, you rule!

CF is really the way to go being compared to plywood and acrylic. And it's still relatively cheap.

Tap/hold keys - some questions/problems

Guys with 100+ keys on their boards may just stop reading this right now. The idea of using tap/hold keys is here for a while already. Short introduction: tapping on a key results in a Tab keycode being sent, while holding is acting like Ctrl. This allows two logical keys on a single physical button...

Cherry keycaps from a rubberdome

I just got two old packard bell keyboards, 5130 and 5131C, PS/2, both rubber domes.
What's interesting, the keycaps fit very nice to a cherry switch.
Can post some photos.

This is a very cheap source of cherry keycaps.

These two are pretty awesome and evolutional over original BlueCube. DSA's look way better on that type of keyboard. Have you dropped trackpoint completely or are going to add it somewhere on the case later? Or tmk's mouse pointer thing does its job well? Both variants look like you don't need tenti...

That's a problem. People buy ALPS/Matias and have the same problem. Pretty sure if we make a group buy we can order caps for it. I would go for spherical.

Looks extremely nice! I've made a case from bent 1.5mm laser cut acrylic plate, but i feel that plywood would be better, since it's less brittle. The bad thing here is that you would need to desolder the switches, mount them to the top case plate and then solder again. I went through this. Probably ...
