Generally that won't work because most hall effect sensors for keyboards utilize threshold detection inside the sensor rather than the MCU. So all you're getting is on/off signals.

These switches were provided to me by Jesse from keyboard.io, so he'll have more info than me. He also works fairly closely with Matias so I think he'll have the best analysis at this point (though I can tell you what's going on in the force curve). Basically, between the different versions there ha...

I think the contacts may not have been working, I'll see if I can remeasure it.

I think that uses the 4th gen Fujitsu leaf spring switches, which have a single piece housing for the whole keyboard (like a model m) and uses a mylar sheet for contacts ( also like the model m).

I do have some force sensors that have a higher rating (not as precise though). The calibration takes quite a while so I'll probably need to hold off on that for the time being.

Haha, the force gauge is safe up to 600 gf (and is critical around 1200 gf). So I wasn't super worried with this one, lol.

Yeah, it feels a lot heavier than it actually is. I think this may have to do with the amount of momentum your finger has when pressing a linear switch. For a linear switch your finger knows to keep pressing even harder to go down. But for a switch like this (as well as the later half of parabolic s...

It feels like your flicking something when you press it. Quite smooth too.

Honeywell Microswitch 1KST3-T (Metal Keyswitches)

Well, these are interesting. Cast metal (likely aluminium) keyswitches! They have small microswitches inside of them, along with rubber gaskets (probably ultra extreme environments). Going from the pins, likely hotswap as well. https://farm5.staticflickr.com/4599/25305994098_ed258a3656_h.jpg IMG_201...

At least from my understanding, I'd say it's mostly On/Off. In theory, if you could ramp up/down the magnetic field as you pressed the slider in a similar range to the magnetic field generated by the pulse, you could measure the output current (or voltage). But this is pretty tricky (calibration nig...

My rule of thumb. If you like MX Clears more than MX Browns, you'll like the Halo Clears. It has more of a feeling like an MX style switch with awesome tactility. Otherwise Halo True is for you. The Halo True has a gentle and smooth lead-in (due to lower preload) and higher final resistance to help ...

I'm running around today (with it being the launch and all), so this will be a bit shorter than I'd usually do for something like this. Really, it came down to reducing the number of SKUs.

Basically, we had to make a trade-off on the pcb in order to support hotswap and RGB at the same time.
