Ringing Filco Majestouch-2 Plus Expanding Polyurethane Foam

[alaricljs]

I've got 2 that don't do any more than the standard spring-ping, and I don't type hard enough in normal usage for it to be detectable at all.

I heard you giggle!
Obviously you realized how funny it is to do arpeggio on a numpad. :happy:

[The Solutor]

It's clearly not a soldering or a Cherry MX individual switch defect problem

Is clearly not a single switch problem, soldering could be still involved.

The only way to exclude it is resoldering all the switches, as i did.

[The Solutor]

I already did that. See the Kinesis Mod in my sig.

Ok

Rang before.

Rings still.

 
Its also strange that rings with blue switches, usually are the brown ones more prone to the problem.

BTW I found this video of Xarmor in the mod section altough not meant for this pourpose the owner pushes the keys pretty hard and no pinging is present, I used mine for just few hours before the switches change so I was unsure about the original sound, even with the original switches Xarmor's ound is still one of the better parts of this keyboard.

Actually if my hypothesis is correct and this is mainly spring sound amplified by a metal plate then the underlying switch should matter little.

 
I think your hypothesis is correct on this board and maybe on filcos.

I think the main variable should be the plate height.

Likely in those cases the plate has more clearance from the switch border so no matter how you push the switch the plate is still free to vibrate (and the switch too).


While in my case the switch (if correctly soldered) touches tightly the plate, and they dampen each other.

You ever heard of The Law Of The Instrument.

 
No never heard, looks like is aimed to the new continent

BTW exceptions (if any) are useful to confirm rules

[Dwipster]

Anyone had any further success on getting rid of the Filco ringing, except for that injectable-foam mod that I respect someone for having done but have no intention of doing? I just got a new FKBN87M/EB2 tenkeyless and it rings like crazy. My older FKBN87M/EB (note: original series, while new keyboard is series 2) has no ring at all. The new keyboard has some keys that ring a tremendous amount, especially the equals sign, space bar, x key, and backspace. Other keys have hardly any at all, such as the h key, v, c, e, and others.

It really is pretty annoying. Any success stories fixing it?

[litster]

I LOL'ed at your name, Dwipster!  Welcome to GH!

[keyboardlover]

Weird, I thought Ripster said only me and Redpill found the ringing annoying.

What exactly does the dental floss mod?
Do you wrap around the cherry mx stems? Like the o-ring mod?

[The Solutor]

In the exact moment you open a cherry switch, the ping is fixed, no need to add any dental floss.

[morethanless]

So, for dental floss you need to desolder the switch too. Because without that, you can't open it. Right?

[The Solutor]

Right.

BTW I'm not sure the dental floss will work nicely on springs meant to be compressed as happen on springs meant to be flexed.

Btw: how do I remove my left shift key? It rattles. I want to pull the keycap but I can't do it.
I already looked there http://geekhack.org/showwiki.php?title=Island:12649

SO I'm lost, without desoldering

[The Solutor]

just remove the neighbor keycaps and use your fingers, when the stem is freed, slide the keycap on one side until the stabilizer is disengaged, then slide in the opposite side to free the other half of the stabilizer.

[morethanless]

I can't do it. If I pull up, nothing happens. I can see the metal wire and part of the right stabilizer. on the left, the keyboard case does bother me.

PS: I added a smartphone camera picture.

PPS: gn8, I'll try again tomorrow. it is 1.30am

[The Solutor]

Remove also the CTRL and Capslock Keycaps, and use both hands if needed.

Surely you have a keycap little tighter or a switch stem slightly larger than normal, but other than exceptional cases nothing to worry about, just more force needed.

[morethanless]

One last question for today
Did I understand corectly that when the switch is up (neutral non-pressed position) I have to pull up, even though it feels like the metal stabilizer would hold it down?

[The Solutor]

No the stabilizer, being hinged, has enough clearance to let you free the keycap from the stem, half cm or so, try to remove th other shift or backspace, maybe they are less tightly coupled and you can practice with them.
