Quick O-Ring Installation

Just use a "Stabilo" pen cap (the hexagonal ones) to shove down the ring. Works way faster then shoving it down with something else, like a screwdriver.
Happy modding :).

Can you post a picture from the bottom side of the caps?
I ran some tests on making my own wooden caps some time ago. They are working but I should cut them to size and I fear, the stem-mount will break off some day.

For anybody who's wondering what the line does: it takes a screenshot of the whole screen, feeds it into imagemagick, calculates 100-mean% value of the image in greyscale and feeds it into xbacklight, which sets the led backlight brightness on my netbook.

You can get typos quite quick (i.e. triggered keys next to the pressed one), if you lower the sample rate in your controller. If I set the value for a detected keypress down to something like 6 successful scans, I get bogus keypresses due touching the other keys lightly. It's not only restricted to...

If you don't want to carry the board arround, installing a non-removable cable becomes an option. I'm quite happy with USB-B because the sockets can handle some abuse (and I didn't had any othe sockets around for testing the footprints). Using pure SMD sockets bears the problem to rip-off all connec...

I used a minimum spacing of 5mm. If you use 4mm, the keycaps will touch (they are 18^2mm). Feel free to use http://hannover.ccc.de/~imp/tasta-12mm.svg as starting point and http://hannover.ccc.de/~imp/tasta-12mm.nc (g-code) if you want to give it a try.

Since i own a freshly cleaned 1800 i'm very excited about your controller project. About the placement of the usb-ports: Hmm the 1800 has some very nice flat surfaces at the rear face, perfect for openings.

Thanks for the inspiration! :) I'm a little concerned about the 14mm^2 holes; as i'm using a mill, it's tough to get sharp corners on inside pockets, and the cherry's have most of the "lip" on the corner.

Based on the idea to make a working keyboard with it: use MX switches and magnet rings (such stuff really exists :)), so the "bump" on the lower side of the switches doesn't matter that much (maybe cutting it off is an alternative, if one removes a little bit of the stem too). Then it's all a questi...

Why USB 2.0, not 3.0? Because kicad doesn't make it easy at the moment to make impedance controlled tracks :/. So it would cost lots of time to make it right, or to screw it up in the end - that's why I went with 2.0 for this iteration. Oh, and I don't have any 3.0 devices around, so it doesn't bot...
