Re: [Done] CommonSense controller - better capsense!

This is not xwhatsit which has custom hardware - this is a Lego set of standard bricks. You can build, like, WORLDS from those - but it requires imagination, skill, and some thinking. Great analogy. Might i suggest that the part of the keyboard community that can do this - help create more document...

Re: Alternative capsense patterns testing

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...

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

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...

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

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...

An XT has 83 keys, 83 barrels, and 83 flippers. The barrel under the space bar is different though, so should be replaced. You are correct that extra barrels are needed for Backspace, Enter, shifts, and Win keys.

Curving the top plate is easy if your fabricator/machine shop has a slip roller. Controlling the XTant was fiddly because the xwhatsit sets a single threshold for the entire board. DMA's CommonSense controller has per-key threshold and costs much less at just $10. This is the way to go. The XTant la...
