Move over Hall Effect keyboards, hello TMR!
Fairly recently, Akko/Monsgeek released the "FUN60" line of budget 60% keyboards, and while there are a bunch of variants of this keyboard, the highest end version of this keyboard uses a technology called "TMR" or "Tunneling MagnetoResistance". Allegro systems which makes these kinds of sensors has a great little video on how this works: https://www.allegromicro.com/en/products/emerging-technologies/tmr What's cool about the keyboard itself is that Akko also built a chip and PCB that not only will process data from the TMR sensors, but can also process data from normal mechanical switches allowing you to put Magnetic switches OR mechanical switches into the keyboard. The TMR sensors are 10x more adjustable than the Hall Effect switches allowing you to adjust actuation points in 0.01mm increments, which is absolutely ludicrous since you'd never be able to detect that small of a movement with your fingers, but it does make for a very consistent an...
