i am typing this post with my prototype chording glove

For the moment it's a winter glove, seven switches, fourteen long leads and a populated breadboard, so it sucks pretty badly for typing, but once I get it off the breadboard and into a pair of 28-pin wirewrap sockets it'll be much more convenient. Ergonomics seem pretty decent so far, although the current keymap is terrible and I plan to write a new one.

What about the Twiddler's keymap? Is that the same? If not, you might rip that off -- I've heard a lot of good reports about it.

Also, have you thought of adding a 3-axis accelerometer to the glove? Chorded mouse!

I was actually planning on having the mouse be a separate glove, because unless I want to do some hardcore multiplexing, it'd be a real pain to have both keyboard and mouse signals going over the same USB channel. (Yes, it's a USB keyboard. I laughed like a little girl when I got it working -- I've never been more excited to see the letter 'w' appear in a terminal window in my entire life.)

But yeah, I already have a couple of 2-axis accelerometers and an ATTiny that I think will work just fine for a mouse. (Unless you can think of a reason why I'd need or want a 3-axis accelerometer. 2-axis seems simpler, and it's a tiny little chip -- the ones I have are SMD.)

I haven't looked at the Twiddler keymap yet, but will have a look at it; I'm sure there are several options.

Oooh, can you mount the accelerometer dead-bug style between the pins of the ATTiny?

I could lay it on its back, sit it on top of the ATTiny, and either wirewrap the pins of the socket the Tiny sits in and (carefully, at as low a temperature as possible) solder the wire to the exposed flat bits on the accelerometer (it's SMD), or solder to both the Tiny and the accelerometer...
