I think I have all the parts I need for a keyboard force curve tester. I still need to build a mounting bracket, reverse engineer the USB serial output from my force measuring tool, and build the integration between the measuring tool, gantry, and actuation test

And I can pull force data for a key switch.

Can anybody guess what switch this is from the data in the video?

Ok. Maybe this will make it easier. Anyone want to guess the switch from this chart?

Next steps involve some bulletproofing, key actuation detection, and something to automate graph plotting. but that will take this beyond the realm of the one afternoon hack.
