A while ago I made "Infrared Super Switches" by replacing the springs in key switches with springs meant for ballpoint pens, resulting in switches with an actuation force of around 600gf (where a normal, sane key switch is like 40-60gf). Later I made a 2% Milk macropad with a couple of those in, but I decided to try making an entire keyboard with these ridiculous things.
The result is what I call the Corne From Hell. EVERY switch has the springs swapped to one of the novelty ultra-heavy ones. I used Akko CS Radiant Red switches, which were rated at 53gf before I got to them. It takes around 28lbs. of force to push down all of the keys on one side of the keyboard at once. If you use this thing, you will probably get amazingly strong fingers, which I assume would be useful for something.
Also features:
* A USB-C port
* A terrible set of random Pudding keycaps plus a 3D printed yellow skull keycap and outlet one of my Lego keycaps
* 3D printed plates/covers in bright red PLA, with cartoon demon decorations (also 3D printed)
* Mysterious stickers on the bottoms
* A slightly disconcerting bag containing extra keycaps, a keycap pulling tool, a USB-C/USB-A cable, a TRRS cable, and some extra regular strength key springs.
