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...
Well, those hand-supported prior arts do obviously function, strictly speaking, so the PTO is satisfied. It's just that that mimimal, technical level of...
I'm now blogging my keyboard attempts. I'm up to the Mark V, and it's still not quite right. All suggestions gladly entertained. See below: -- --my blog is...
All I would say (there's always something :-) is (a) You maybe could cut some rectangles and slip them into the boxes (what are these more precisely called ---...
Microsoft is promoting a new, smaller type of tablet PC they call Origami. It looks like it has a stylus but no keyboard at all and will rely on hand writing...
John, The UMPC doesn't rely on hand+voice - MS has a thumb input system as pictured here: http://www.engadget.com/2006/03/08/cebit-web-site-shows-origami-ui/ ...
This is for the benefit of anyone who doesn't subscribe to the Wearable Hardware Discussion List [1]. Daniel Hengeveld supplied there a link to a very...
Hello, I'm sorta new to the chordic input device thing, although it blends nicely with some of my current interests. I came across this story in the back of...
