If you are want to look at these switches before buying, you can go to radio shack and check out part #275-017A. These radio shack switches are almost...
Currently, I'm experimenting with mounting the switches. I've made several trips to Radio Shack, Orchard Supply Hardware and Home Depot looking for materials...
Check out the "minibox" project here: http://w1.132.telia.com/~u13205992/buttonbox/index.htm It looks like the author has written code for the Atmel that lets ...
Good idea. One thing I should probably say here is that, IMHO, it's very important to select the switches and key caps carefully. There is a huge difference...
This updates and replaces a previous note. Here are _two_ approaches to adjustability, offered not as serious designs but merely as an argument that...
Here are 2 adjustable strategies I've been considering: 1) Telescoping arms. 2 thin tubes(one slightly thinner than the other) and a tiny clamp(to freeze the...
For a while I played with (fiberglass) perf board. I figured that since (a) it has a 1/10 inch grid of holes and (b) you can buy switches whose connectors are...
I've been playing with OpenOffice and have produced some more crude figures: http://www.chordite.com/garage.htm These might resemble what a product would look...
Dang. Somehow checking the relative address box in Composer in Mozilla 1.2.1 doesn't seem to be having the right effect. So I edited it by hand. Please try...
I've just fired up another kingpin-style prototype, this time using Omron D2F-FL switches (p823 in Digi-key cat. T031). They're smaller and lighter than the...
Lately I've been thinking idly about exactly how one should scan a hand to get the dimensions that would enable a miniature milling machine to carve a keyboard...
Hiya everyone, i've been following this board and the site for a while now, and really want to have a go at building my own keyboard. My problem is that i live...
Hi Zak, Digi-Key, www.digikey.com , seems to work in the UK. There's a little Union Jack at the top of their home page. Just click on that and off you go to...
I checked Uk.Digikey.com, and.... £25 for one chip if you include shipping and handling :( So back to my original idea, could anybody send me the chip, just...
Hi Joseph, The main issue is how to get the keyboard software (firmware) into the chip, i.e., how to program the chip with the free downloadable keyboard...
OK, I think I've got most of my confusions cleared up. Ignore everything I said before. (1) Of course John Tokash is quite right, PonyProg is free: ...
[I swear, I feel like I've already posted this before, but can't find the post... Ah, well.] Ah, yes. The idea for a thumb "mouse" - or at least some sort of ...
Once upon a time, somewhere, I saw a guy using a pointing device that looked like a ball-point pen with a half-inch ball and a cord out the top. You held it...
Well, I finally got all the parts together for the simplest programmer I could find, it was basically 4 resistors. I can not get it to work with Ponyprog...
First I have to say that I am _very_ impressed with John's innovative design. Secondly, I am _very_ impressed that he has made the design available to...
