It's always cool to help showcase a Canadian keyboard
:D

Some of my collection made it into this book :D

@obra @ktemkin Last I checked Linux doesn't even have code for this (I had started to make some patches but then got sidetracked with the pandemic).

I actually need to go through this exercise pretty soon for my new rust firmware.

[Jacob Alexander @kiibohd]

@obra @ktemkin I'd like this too, haha. For HID a large part is actually verifying what the OS does with the HID descriptors. As your well aware, it doesn't matter if you're compliant with the spec, if the OS doesn't implement that corner case correctly.

It's been a while since I talked about keyboards!

@obra I think I've been on nightly since 2015.

[Jacob Alexander @kiibohd]

@obra I don't believe so. An end user can get in trouble of they use the device outside of the labeled function (though you might have to add some extra labels). I haven't looked too deeply on this though.

[Jacob Alexander @kiibohd]

@PhillipWitz @lunasorcery Yep, putting some tape can work. Or switches with tighter tolerances.

[Jacob Alexander @kiibohd]

Interesting looking diodes too.

This is only the 2nd Alps Magnetic Reed Switch keyboard that I've seen! What's even more interesting is that the switches are slightly different (more modern). So these were used enough such that Alps made at least 2 models!

Not 100% on this yet, but I suspect this is where the keyboard matrix is encoded (using a "table" of resistors) https://t.co/R5Q7j5RtPJ

[Jacob Alexander @kiibohd]

Notice how this switch has the diode built into the switches (some variants of Cherry MX and other mechanical switches were designed this way to simplify pcbs).

1975 Alps Magnet Reed (https://t.co/ovNfa1qdt8)

[Jacob Alexander @kiibohd]

https://t.co/aOCGJjUZhb the first one (circa 1973'ish) apparently came from a box that said "first computer at UCLA" (though I don't have any way of validating that).

[Jacob Alexander @kiibohd]

It's only taken 7 years, but I've finally found another one. Full dismantle soon!

@TubeTimeUS @mcedeveloper Early optical switches actually used lamps. Burroughs experimented a lot with optical switches.

[Jacob Alexander @kiibohd]

@TubeTimeUS There's a theory floating around that ferrites used to be quite cheap, and then a crash of sorts happened in the Soviet Union and then ferrites became a lot more expensive and thus couldn't compete with increasingly cheaper switch options.

@oulasvirta @yichiliao @cherrymx @AaltoResearch @sunjun_kim @byungjoolee85 Very cool! I really like the iterative compensation approach to compensate for error sources.
I wonder if it would be possible to integrate the vibration into the Moticont linear force actuator? This would likely require a more powerful MCU (possibly DSP) though.
