got a keyboard here with 170cN of force needed to actuate the keys.
anyone beat me?
-
Proof? As in RipOMeter test. And what keyboard is it? You could certainly be lying... I might as well say, "I have a keyboard which requires 500cN of force to actuate...
-
what kind of measurement is c in cN?
you weird americans, still measuring in body parts
-
Centinewtons.

Likely many ATM tamper-proof keyboards.
-
centinewtons.
omg
-
centinewton=gram
-
centinewton=gram
Hahah.
I read too fast from the phone.
I interpreted it as centi-new-tons. (so i thought to some obscure imperial unit).
I hope next time gravity will be discovered by John Smith:happy:
-
Then it would be called centi-smith :bump2:
I still wait for the OP to disclose his keyboard model.
The heaviest key I tested where MX black with end-force of 80g
-
centinewton=gram
If only the meter had been chosen to make g = 10 m/s².
-
More like "if only the almighty had made the Earth such that g = 10 m/s²".
-

Yes, less misunderstandable...

The stiffer I tried (other than the tamper proof ones) is the BL82 with the silicon membrane installed I haven't measured it but should be more than 100g, i tested the switches w/o the coiled spring and the keyboard was still usable.
-

I haven't wrote it, as I've been accused of being pedantic...
-
Pah, that's only details and rounding erros.
centi newton = gram is ok for this thread, we don't make keyboard science (I leave that to Ripster)
-
Here you can calculate your personal G

just click on start GIS

And 1 atm=1 bar...
-
What is ATM?? automated teller machine?
I know that ATÜ is an old unit equal to n+1 Bar.
And there is hPa = mBar
-
What is ATM?? automated teller machine?
Yes, at least in Italy we call them Bancomat (just noticed I managed to use the same acronym with two different meaning in the same thread :) )
Intended as a pressure unit, 1 atmosphere=1.01325 bar, or as you said 101,325 Pascal
or
1 bar = 100 Pascal = 0.98692 atm
-
what.
SI units are superior to americans however
-
Grams and Newtons are both SI units
-
This? http://www.nicomatic.com/_uk-145.htm

Just an American unit for atmospheric pressure
1ATM=760mmHG=760torr

Not really an american unit, just an old international one.
-
I've typed on vintage terminal keyboards where the set-up buttons used a stiffer switch than the normal keys to prevent accidental presses. Probably in the 100g+ region.
-
1 atm = average atmospheric pressure at average sea level = 101,325 Pa = 1.01325 bar = 760 mm Hg = 760mm Torr = 14.696 pounds per square inch
STP = 1 atm at 273 K
-

Oh okay, thought it was something like how we use inches/centimeters whereas the rest of the world uses meters.
-
Torr is totally new for me.
-
Torr is totally new for me.
Torr a unit is dedicated to Evangelista Torricelli the Italian who invented the mercury barometer.
Is still widely used as unit of the human blood pressure although not part of SI
1 Torr = 1mm of mercury (at sea level) on the one meter long Torricelli's tube, as you may remember from the school time the normal pressure is worth about 76cm of mercury on such tube.
So 760 Torr

I put a spring from a ball point pen in my Caps Lock once. (Using Cherry MX Browns) I didn't measure how much force it took to press it down, but I would think it was well over a kilogram.
First time I pressed it I thought it wasn't going to budge, but sure enough I just really needed to lean on it. It did the job of preventing any accidental presses, but I thought maybe it did too good of a job.
I ended up using an MX Gray in my Caps Lock and an MX Clear on my space bar. I don't like the Gray switch in my space bar. It should be much lighter than that, IMO.
-
I have an "ergo gray" on my spacebar (gray stem, clear spring) in other words it's just a clear, but grey

Interesting how the OP hasn't posted at all yet... But those metal domes look pretty awesome :)

Imagine the 500g version... ouch
"Already tested in a diameter of 5.5mm and 280g activation force (2.8 N) or 5mm and 170g force (1.7 N), the product is customized upon request with forces ranging from 100g to 500g and more!"
-
What is the point of a button that you actually have to attack to actuate it? I mean... there's vandal-proof and then there's daring the vandal to blow **** up.
-
The 500g is perfect for him
EDIT: and watch till the end.

It can only be a razer blackwidow the way the keycaps just fall off like nothing

He won't. At least, not in a serious or helpful way. It's the same guy who popped in a while ago and started the largest troll thread (http://geekhack.org/showthread.php?18454-You-re-are-all-gullible-fools-who-are-easily-parted-with-their-money.&p=352504#post352504) I've ever seen.

He wants you to eat your melted ****. True story.

Hey, perfect translation
But you forgot to mention he calls you 12x sonofa*****.
And 8x "I'll kill you all".
So far

German hissies are scary.
Five years of german were not wasted ;)

...but my 5 years of French were, definetely!
