nearly a decade ago I discovered a bug in my keyboard and it made me so angry that I had to get into mechanical keyboards and making my own keyboards to avoid it.
-
if you can't type a common english word in all caps while being a little fast and sloppy with your typing, your keyboard is broken. you should exchange it for one that is not broken
-
My laptop keyboard does this too, but only with certain letters... so M and Y didn't work, but most other letters do after M, but if I press Y first then L doesn't work but most other letters seem to.
Is that normal or is my keyboard supper broken?
-
technical shit: this is anti-ghosting. Keyboards without diodes have a matrix problem where holding multiple keys means it becomes impossible to determine what keys are pressed: to avoid incorrect keys being pressed, it just ignores both the incorrect and correct keypresses
-
the way you solve this is by either:
1. being clever with how your matrix works. this technically leaves anti-ghosting issues but you can at least limit how often they happen, and on one key combinations.
2. PUT FUCKING DIODES IN YOUR DESIGN YOU CHEAPASS PUNKS -
the thing is, there's several keyboard designs where they are not clever with their matrixes.
Here's a fucking hint: modifier keys like ctrl, alt, shift, windows? they will commonly be pressed ALONG WITH letter keys. PUT THEM ON DIFFERENT COLUMNS YOU PUNKS -
my whole deal is making BAD KEYBOARDS and even I am yelling at you for how bad this keyboard design is!
-
and it is shift that's the problem. If I do my keyboard test from above without shifting, I get "my" correctly.
-
do not get a dell latitude 7400 if you are planning to type on it
-
@adaliabooks that's normal if you have a badly designed keyboard, yes.
-
this is merely a fundamental problem with making keyboard matrixes and we've understood how to fix it basically since the first day we started making keyboard matrixes
-
diodes are about a cent each in bulk.
adding them to a keyboard increases the cost by about a dollar. it's required for them to work correctly, but apparently there's a large market for 1$ cheaper but broken keyboards -

@foone aside, everything I wanted / needed to know about keyboard matrices, ghosting and blocking, etc. I learned from Tiger-Heli's website on Mameworld from 2003: https://www.mameworld.info/net/emuadvice/keyhack2.html
THIS is a goddamn good website. they sure don't make em like this any more
-
I grabbed my nearest Bad Keyboard. I paid 2$ for this keyboard and another 9.95$ for the stickers.
But it lets me type MY and my built in one can't.
-
Well, not much I can do about it as it's attached to my laptop. Can't say I've ever noticed any issues when gaming, but then I do mostly use a controller for faster paced games anyway.
-
@adaliabooks for me it's not gaming, I never notice the problem there, it's just typing. I often want to type things like "MY GOD!" but half the time on this keyboard, it comes out as "M GOD!"

@foone can’t decide if I’m annoyed by shitty keyboard rollover or whether it’s my own fault for sloppy typing.
-
@ozeng bah. compuers are built for humans. if humans type sloppy, the computer should (and can) handle it
-
@foone MMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMYYYYYyyyyyy
