What if your keyboard pushed back when you smashed it — and charged itself when you did?

Imagine key switches with magnetic resistance:

Type softly → light, smooth, effortless

Slam keys → resistance increases automatically

The harder/faster you type, the more energy you generate

No gimmicks.

This is just physics.

Moving a magnet through a coil creates:

Electromagnetic drag (speed-dependent resistance)

Electrical energy (regenerative braking, but for fingers)

Same principle as EV regen — scaled down to millimeters.

The result:

Softer typing when you’re precise

Natural anti-smash protection when you’re not

Trickle-charging the keyboard while you work

Battery lasts longer because you’re working

Not “active haptics”.

Not “AI”.

Just elegant electromechanics.

Typing becomes: Input + feedback + energy recovery

instead of dumb plastic switches wasting force.

This is the kind of hardware we should be building when we stop shipping toys.
