These pages document a part of my project to create my version of the wearable PC. For more information about the project in general, go to the projrct's main page. This part of the project is both the computer's keyboard and its mouse (although I may add some other pointing device later). It is a Chordite keyboard as described by John McKown on his website, but I have made some improvements to the mechanical design (or at least I think they're improvements -- Mr. McKown and others are of course entitled to their own opinions on the matter).

Basically, I've replaced the kingpin from his design with a pair of offcuts of "deck track" meant for model yachts. This deck track is made by SAILSetc and is available from various hobby shops and the like. I got mine from Radio Yacht Supplies Australia, who were very nice to deal with, but their online ordering is a bit "primitive" with no secure credit card facilities. I still have each keyswitch on a piece of coat-hanger-type wire, but instead of these wires all being mounted on a single kingpin, each one is individually attached to the deck track via a U-shaped piece of unbent paperclip wire. The advantage of this is that it makes each switch's position individually adjustable without impacting the others' positions. It also means keyswitches can be added or removed at either end of the track without touching the other switches.

I'm getting sleepy now, so I'll have to finish this at the weekend, but here are some pictures to be going on with.

And links to more. These are all the "big" versions, about 300KB each.
