Re: 65% Model F – Open Group Build

I finally found my cheat sheet with post position measurements on it. There is about 1 mm between caps, so the actual caps are about 1 mm smaller than this. It is marked to .001 precision, but don't believe that. If you are off by 0.1, everything will work fine and no one will notice. I would not be...

Re: 65% Model F – Open Group Build

i think it is worth trying - make the bottom row pads slightly wide to accommodate as many different layouts as we can. We would need one more pin for a new column, though. Any suggestions as to what pin to use? And what pins to use for the TP option - with consideration for routing? Though i sugges...

Re: 65% Model F – Open Group Build

My fault for not explaining it well. The key cap "value" is not so much a problem - it is possition. Right now, there are 3 possible configurations; ISO Enter and the cap left of that, ANSI Enter and the cap above that, or 1u + 1.25u + 1.5u on the row above. I could "free up" one pad by saying that ...

Re: 65% Model F – Open Group Build

Right now, Enter plus back-slash are using 3 pads; Enter covers two pads, but only uses one (same) pad for sensing in ISO and ANSI config, the second for stabilization, and the third for back-slash - second and third swap depending on ISO or ANSI. Hypothetically, i could use the same column and row ...

Re: 65% Model F – Open Group Build

Split spacebar was seriously considered. It was not selected for 2.5 reasons; Code key caps are rare (you can't order them from Unicomp); the "small" spacebar is 5.75u wide (could not fill this space with just Code key caps); and we have exactly 70 pads already (5x14 matrix - so would need to activa...

Re: 65% Model F – Open Group Build

It may be possible, but it would probably have to be flat. Most keyboards mount the switches flat and use different key cap profiles on each row to give contour. Buckling spring key caps all have the same profile and they mount the switches on a curved plate to give contour. I also don't think that ...

Re: 65% Model F – Open Group Build

The pad card PCB would be 0.8 mm thick - how brittle this is - is worth learning. The bottom plate would be 3d printed, so non-conductive. The smaller footprint for capacitive pads is good to know - i am also working on an MF re-design to take advantage of CommonSense larger matrix support (6x20 mat...

The testing discussed here was done on two layer PCBs. Four layer PCBs are not much more expensive - and could benefit from more development. The top two layers of 4 layer board are 1/10 the thickness of 2 layer board, so signal strength should be much better. The third layer is well placed for a gr...

It is not about one or the other, it is about options. Our plan is to design "keyboards" (not "a keyboard"). But some features - such as "controller on pad card" and "bezel-less layout" will be very difficult or impossible with a curved back-plate. It is possible to make a buckling spring HHKB (abou...

Re: (Model MF) Remodeling the Model M (aka.. the Mara)

As for the pin or buttress debate, i like to use neither. The purpose of the pin or buttress is to prevent the barrel (and key cap) from rotating around the "chimney". What works just as well and i think is more aesthetically pleasing is to use something under the top plate that prevents the rectang...

Half holes at the back is good, but might impact lateral stability of the pivot plate. How about immediately forward of the fulcrum? Change in capacitance is generated by change in distance between the pivot plate and card pad. So it should be that the most impactful bit of the pivot plate is the bi...

Re: (Model MF) Remodeling the Model M (aka.. the Mara)

if the rows are offset by a half unit (as they are for most of of a "standard" 60%) do the quarter-rounds form round holes? It kinda looks like this would work for non-stagger and quarter-stagger but half-stagger maybe not.

Model M barrels are the same as Model F barrels - so the barrel frame and case of any Model M can be used. You just need a new pad card, pivot plates, and controller. The discrete barrels of the AT, XT, and 122 allows rearranging the switches into ... pretty much any layout (just like Cherry/Alps) l...
