Tell me how many nickels it takes to depress the keys on your keyboard! - Page 15

post #141 of 267
Thread Starter 
Webwit, I swear all you do is argue over the internet. I'm starting to wonder how your relationships go outside of keyboard sections on the internet.

The thread "IS" called "Tell me how many nickels it takes to depress the keys on your keyboard!". Which means exactly that.

This may come surprising to you, but I did not get this idea from ripster, I had a bunch of change on my desk and dimes were too light, and quarters were too heavy, so I chose nickels. (And after some time on Google I found out nickels were the only coin type that had a rounded number besides a penny which was too light.)

I decided to do this when I first became interested in Cherry switches because I was curious as to how much force was required to push them down in relation to the graphs I saw in the mechanical keyboard sticky.

Inaccuracy or not, it's all about nickels and only nickels.

Thank god for the OP gettting this thread back on track.

It took me these number of nickels on these Cherry MX switches.




I think on one of them I cheated and used a 50g weight.

Notice that the Cherry Clear bottoms out much lower than the official Cherry Force diagrams. Bad day at the spring factory?, new batch of Hanzo Steel?, different gravitational pull in Munich?

I dunno. Science is sometimes hard.

Once again Nickels To The Rescue. They have the same activation point.


They ARE different though. Details here.

Nickels are great for getting things ballparked and making switch and mod choices. They obviously don't replace feeling the tiny differences in switches (although I doubt Human Fingers have 1g accuracy).

Man argues on-topic mechanical keyboard issue on keyboard forum. Surely that is totally out of line.

+-3, which was the point, and no one managed to prove otherwise. It's curious you don't want to try to listen, but wanted to reply to it anyway.

FWIW, 1983-2009 pennies should weigh in at about 2.5 grams (the mint says the ones after that do too but I don't believe 'em), which is half of a nickel. Using one of them at the end would allow for half-nickel measurements.

So when the last nickel is added that depresses the switch, it can then be removed and replaced with a penny to see if it is less than or more than .5 of a nickel.

I recommend dithering to get +/-3g precision. Tap your keyboard tray or desk with your index finger three times saying, "Rip" - "O" - "Meter".

From wikipedia

Quote:
…one of the earliest [applications] of dither came in World War II. Airplane bombers used mechanical computers to perform navigation and bomb trajectory calculations. Curiously, these computers (boxes filled with hundreds of gears and cogs) performed more accurately when flying on board the aircraft, and less well on ground. Engineers realized that the vibration from the aircraft reduced the error from sticky moving parts. Instead of moving in short jerks, they moved more continuously. Small vibrating motors were built into the computers, and their vibration was called dither from the Middle English verb "didderen," meaning "to tremble." Today, when you tap a mechanical meter to increase its accuracy, you are applying dither, and modern dictionaries define dither as a highly nervous, confused, or agitated state. In minute quantities, dither successfully makes a digitization system a little more analog in the good sense of the word.
Trying to get more precise than that is just dithering yourself into a highly nervous, confused or agitated state.


Or if you have a Yen for false precision.

65 Yen.

I've just realised i have a load of 5G weights in my desk drawer.

Edit: I can't stack enough to press a key down
