I've just done a first trial run at custom fit "grip frame" that could substitute for the kingpost style frame that appears to be the current dominant chordite...
That's brilliant, John! Other than the procedure you describe I'm slightly stuck on how to fabricate the back brace and get your hand back out. I've been ...
I've recently been playing a lot of WarioWare Twisted! for the GBA. It uses a gyro sensor for controlling dozens of minigames. Here is a video I made(with...
Very cool. This makes me think of one of my dimmer ideas; the self-illuminating flag. Woven into the flag's fabric are long cylindrical piezoelectric threads....
One way to achieve a wireless, wearable, chording keyboard might be to hack a wireless qwerty as follows. Suppose you have a commercial, wireless qwerty...
I've been poking around some of the "Small Business Innovation Research Program (SBIR)" sites [1], checking out what Uncle Sugar might do for the cause of...
David, Thanks for the heads-up, it just took mouser 12 days to tell me they couldn't get me the AT90S2313-4PC. My question is how does the 4PC differ from the...
Hi Jarod, According to Atmel's parts code decoder (http://www.atmel.com/general/ resources/doc0538.pdf) the part number suffix contains the speed (10 vs 4),...
You can load a .hex file such as my kbm06.hex into the chip with a "chip programmer" program such as avrdude [1] or Ponyprog [2] that runs on your PC and works...
Well, I built myself a little programmer and tried it out with avrdude and some ATtiny2313s under Linux and Windows. Avrdude 5.0 seemed to like it at first....
Some opinions voiced at Ask Metafilter [1] on wearable keyboards mentioned the Frogpad, Twiddler and chordite-style keyboards. As usual people seem to see...
Hmmm.... I notice that the chordite version on the front page could be implemented using the poker chip indexing system (mentioned somewhere on chordite.com,...
FYI Russell refers here to the chips that have little gear teeth around their rims, top and bottom, that lock when you stack them. You might have seen them...
I notice that the requirement for adjustability adds considerable mechanical complexity to chordite keyboards. I wonder if, instead, it's possible to make a...
First, I don't know. You might be right. But my prejudice is that adjustability and foldability are best viewed as NRE issues --- more a cost of design than a...
Russell, you might be underestimating the "poor user" :-) But I'd be tickled pink if we could all buy standard-sized, non-adjustable units. It might come down...
Since PS/2 is going away (and gone already for the computers of most interest), all commercial keyboards have to migrate. Atmel has been selling keyboard...
Hmmm.... I've found some nice Marquardt keymodule switches[1], and have gotten some samples. They are actuated using a linear rather than curved movement...
Russell, you're right in saying my configurations to date involve the fingers being less curled than what you're calling the neutral position. Your relaxed...
If I wanted to build a one-hander and didn't want to do it precisely as described at chordite.com (using the middle and distal phalanges), I'd put the two...
... This is true for me. Unfortunately, the dog ate my keyboard, so I can't test keying. Sigh. I was planning to re-make it from scratch anyway, but I would...
