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
-
First hardware integration test of the force curve tester.
-
OK, I can read the force tester
-
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.
