Keypresses Registring Twice (MX Brown)

[impclaw]

I have a Filco Minila MX Brown, and when typing, about once or twice every paragraph, the keypress is registered twice. This makes funny words like "theye" or "heello". I have used blues for a year or two now and never had this problem. I tried putting my girlfriend in front of the computer and it happened for her as well.

Am I just typing wrong, or is there an actual problem with my keyboard? I live in the middle of nowhere, so sending it back is difficult and expensive.




Here is a gif animation to demonstrate the problem (the word yesterdaay end of third line):

(Sorry for the slow typing, I'm not 100% used to the English layout yet)

hhrrmm..... well... if it's all the keys it could be a solder problem next to the controller..

Or a faulty controller that has problem with debounce..

Did you check it on different computers?

Thanks for your reply!

I have now checked it on a different computer, and also with a different USB port. Neither works well. I don't know if it is all the keys. I mostly wonder if this will go away with usage...

It is a chattering switch. Send it back or replace the switches yourself.

I guess I have to send it back then.

I am finally able to reproduce the error. If I type on the switches very lightly (not bottoming out), it happens much more often. Is it possible that the actuation and reset point are so close, it is triggered multiple times? I just want to make sure this problem is not somehow my fault.

It's not you, it's the keyboard! Especially since you tried on more than one computer.

Keyboards shouldn't ever do this unless you double tap, or have some kind of crazy repeat rate.

Although I'm pretty sure something on the usb bus (sometimes usb 3 conflicts on older machines) and/or some software glitch could cause a similar issue but I believe in that case you would notice because the entire computer would have stuttering. I had that issues once I would be typing and the cursor would stop moving and then just type a bunch of the last character.

Is this a problem with tactile switches? I use cherry red but now I keep hearing about chatter on browns and blues.

You can also use a Autohotkey script to fix that:

$e::
{
Start:
Downkey := A_TickCount
sendInput {e}
KeyWait e
KeyWait e, d T0.2f
if (ErrorLevel = 0)
{
if (A_TickCount - Downkey < 500)
{
Send {F13}
}
Return
}
}

I made this script to fix the same problem on an Azio Levetron Mech 4 (Cherry MX Blacks) and works perfectly!

No its not a problem. They're defective and defective switches come in all flavours. The only time its a problem is when we're talking about blues and hysteresis.

That is a bandage for what should be right in the first place.

Yeah, but it's better than nothing, especially when you have no support or warranty whatsoever where you live at for the keyboard you own.

I hope this is not considered necromancy but I hate threads that end without a follow-up.

I sent my keyboard back to the company but they couldn't find any faults with it. Looking at the switch pressure graphs, it seems that the operating point and reset point are awfully close. My guess is that I type so lightly that the keys accidentally register twice sometimes. This is of course unbearable and I'm already looking to buy a new keyboard. Blues are my favourite but it is too loud for the workplace, so I'm pretty stuck.

Clears?

And your girlfriend is exactly the same when it comes to typing lightly? I would find that conclusion from the vendor very hard to accept if I were you.

You should lend the board to someone who types like a jackhammer and see if it still happens.

I guess you have a point.

I another funny thing today. I decided to switch around various usb cables, when I wiggle the cable (lightly) the keyboard leds flash, the keyboard disconnects and reconnects. Is it supposed to do this? Could this perhaps be the issue?

Sorry for asking all these questions. But I really, really like the layout.. heh.
