Unfortunately the video linked on the page is not working. It would have been nice to hear the difference.

It looks like a pretty good idea if you're into stealth typing.  From what I understand, part of the mystique of the Topre 'boards is the "thock" sound of the keys bottoming out.  I guess there wasn't much mystique in the sound for this guy.  I wanted to try something like this for my Evolution, but I decided not to when I figured out the the clacking of the bottom/top out was inherent (and intentional) in the switch itself.

To me it's more of a soft knocking sound. I don't really like the way it feels or sounds to bottom out.

I was using my MX11800 recently and noticed that it was a lot easier to not bottom out on the Cherry browns than it is on the Alps.  I think the level of tactility plays a part in the ability to bottom out or not.  It seems that the more tactile a switch is, the more likely one is to bottom out. I believe this is due to the amount pressure needed to get to/through the tactile portion, then the necessary pressure dropping considerably past the tactility point.  I'm not too sure where I was going with this, but I just felt the need to share. :)

I find it easier to not bottom out on Cherries too. I think it's the extra 0.5mm or so travel, and they feel more bouncy after the point of actuation.

The bump in the Topre is stretched but the end of it seems so close to the bottom it seems encourage bottoming out. Cherry blacks seem to be the opposite, their springiness helps not bottoming out.

I noticed this, too.  They seem to bounce back more so than other switches.

It's all subjective, of course, although, I completely understand your point.  I guess the best analogy I can come up with is playing tug-o-war.  If you are pulling as hard as you can (or decently hard, anyway) against an opponent who then lets go of the rope suddenly, you are probably going to fall on your a*s (this would represent very tactile switches like the black Alps in the ABS).  If your opponent were to gradually let the rope go, not only would your opponent get a bad case of rope burn on their hands, but you would have an easier time maintaining a consistent pull and stay balanced (e.g. brown Cherrys).  I hope this makes at least some kind of sense, but it does seem to against the idea of having tactility in a switch.

I sort of accomplished this same effect when I painted my endurapro mounting plate with a few coats of plasti-dip. I think painting plasti-dip is easier than the rubber sheet cut outs.

why do pictures vanish in google translation pages?

Hotlink protection. It's seeing the image get loaded from somewhere other than the site that the image is hosted on, and not letting it load.

Hmmm, I guess you can look at it that way. To each its own of course. Sometimes BS fans complain that they bash right through the Browns, almost like they are linear. While I don't have that problem, I do feel its easier to slam them down.

I takes a little while (like 10-15 minutes) for me to get used to the lighter switches.  I don't have as much of a problem with bottoming out the black Alps on the Dell, but the ABS has a different feel, and I bottom those out all the time.  The Cherry browns I have no issues with.

I'm not sure I really understand the concerns with bottoming out.  I guess I type pretty hard, because I seem to bottom out the switches I use (white alps, black alps, and blue cherries), but I don't mind it at all.  

Maybe once I get a brown cherry board, I will see it differently.  I also still have to get a buckling spring keyboard, because I haven't typed on one of those since I was a kid...

I'm not sure I really understand the concerns with bottoming out.

For some, it's speed.  For others, it's the trauma to the hands of the abrupt stop (this is especially true for rubber dome 'boards where you pretty much have to bottom out to activate the key).  I'm sure there are other reasons like noise, for instance.  I, for one, have never really minded bottoming out.  I do notice an increase in typing speed if I lighten my touch and not bottom out.  It's a little quieter with the Alps-based 'boards I use, too.

Yeah, that makes sense.  I probably am used to bottoming out due to my use of rubber dome keyboards for so long.  I'm going to work on making my typing lighter to see if that improves my speed and hand trauma.

Title: HHKB pro silencing by melamine foam
Post by: hasu on Sun, 14 November 2010, 06:27:16

I did silencing on my HHKB pro by rings made from kitchen melamine foam.
Making rings is cumbersome. I used kitchen slicer and two leather punches(9mm, 12mm) to make rings.

55g Realforce keyboards are quieter than variable force...

...just sayin.

Good thing HHKB isn't variable force.

I know that, I was just mentioning that fact for anyone interested. Hence "just sayin".
