http://www.ebay.com/itm/Electrostatic-Capacitive-Rubber-Dome-Sheet-35g-45g-55g/112137004390
Seems these are always in demand. Weights of 35g, 45g, and 55g. Plan on ordering a couple tomorrow :thumb:
Mod Edit: Changed title to reflect that this is technically for Topre clone, but may work for Topre products

Bummer

Could still pick one up, cut out the domes and see if they will work.

This is what I was thinking, seeing as for instance the HHKB already has domes that are cut already.
-
I wonder if this fits in the noppo full size board....mine is currently already in pieces so....
-
mostly curious to if they feel any different because of a slight difference in material/composition. might get a 55g sheet and cut it up for my hhkb!
cool find indeed
-
Granted they are cheap, but you will have to cut them up quite a bit to sit properly in the sliders. I'm not sure if it makes much of a difference, but if the air channels aren't there it may alter the feel and actuation.

I would just like to provide a little more context , the item is listed because I made a request to the seller , the original item is here
http://www.monsterlabs.co.kr/shop/product_detail.html?pd_no=13285
I am also looking into getting these

The gameplan is to get a topre clone like this 62g variant
http://item2.gmarket.co.kr/English/detailview/item.aspx?goodscode=709867469
mix and match springs and different rubber sheets and see what works best

Having those external topre springs would be awesome to play around with and so much easier than swapping rubber sheets.
-
Spring can give weight but are linear the tactility comes only from the rubber.
-
IIRC the Hansung capacitive keyboards are part of the Royal Kludge / PLUM / Noppoo family, so there's a semi-decent chance this will be compatible with those.
Hm...maybe I'll consider trying to swap my RK down to 45g. It's kinda glitchy anyway (and therefore lives in its box), so I don't really have anything to lose...
-
it work with rc930
-
I just ordered a sheet of the 55g, will try a dome swap on my HHKB and report back!
-
Having taken apart a Topre clone (Plum 84) and examined and tested the naked dome sheet, my personal evaluation is that they are noticeably worse quality than a Topre dome sheet. Don't expect a Topre type feel if you put this into your Realforce, HHKB, or Leopold. They don't replicate the feel or have the same type of tactility as a Topre keyboard.

Having tried all the Realforce boards and most of the Plum I'll stick with Plum.
Realforce hurts my hands after about 30 min to an hour of constant typing. Perhaps due to a thicker "higher quality" plate? I don't know.
I'm not an engineer - I don't know what is considered "high quality" inside a keyboard, but IMHO Plum doesn't feel like Topre: It feels better.

Do you find yourself bottoming out when you typed on the Realforce? It could be the metal plate. I'm not sure if the Plum boards are plastic or metal plate, but the plastic plates are more forgiving when it comes to bottoming out.
-
I bottom out. It's never been a problem for me until I started using Realforce keyboards.
I will say however I have not tried the HHKB mostly because of the layout. There is a good chance if it came in a tenkeyless 80% format I wouldn't have any problems.

I thought I'd post back here with the results of an experiment I did:
I got the 55g sheet in the mail a few days ago and swapped half of the domes in my HHKB.
I can't tell if the 55 domes are actually heavier. They DO feel FASTER.... and when I put on my headphones and loud music, I would say in a certain sense they have "more" tactility, I'm not sure I prefer it.
The "butteriness" of the stock HHKB domes isn't present, and it feel a bit more like my Cherry MX browns I'm typing on right now.
Perhaps most surprisingly, the sound COMPLETELY changed. On these 55 g domes, I now have a LOUD clack on the downstroke (upstroke already modded with hypersphere rings). I took of a couple of caps to see if it was the cap hitting the case or the slider hitting the PCB, and I think it is most likely the sound of the cap hitting the case.
I'm really stumped by the sound. It's present on every key I swapped. If the sound was similar, I might consider swapping the whole board - but it's a dealbreaker for me, and without the butter feeling of the topre keys I'm not sure I'd recommend buying these sheets.

I think this is because the replacement domes have holes cut out on the diagonal - below where the legs of the slider are. They usually are stopped by the rubber sheet when the key is pressed. With those cutouts, maybe the slider leg is going past the sheet and hitting the PCB, or the travel is increased far enough for the keycap to hit the plate.
-
That looks like the type of rubber that will eventually crack when under constant pressure. idk :-\

Looks like someone bought the 35g domes and did a swap on an HHKB

Nice to know this, o that I can update my PLUM 84 to 45g or 55g.
It's way too light for my taste now at 35g.

She was fun to make. Harvested the sliders my self and threw on hypersphere rings. I just like the Topre PBT caps better

Could these potentially be used in making a scissor switch keyboard? There are no tenkeyless 87 scissor switch boards and I'm curious if this would be one of the secret ingredients?

I think these would be way too tall to be good for a scissor switch.

Have you guys seen those 10g springs?
Can these be bought somewhere?

The only place I've seen them is with Plum keyboards. I got a bag of them (at least enough to put under all modifiers on my TKL, and then some extra) with my Plum87. I assume the same is true for any capacitive switch Plum board. I haven't tried putting them under alpha keys though. Were you looking for packets of them, or just the one? Since I'm also in Scotland I could send you one if you paid the postage.

I just ordered the plum 84 from aliexpress, should be on its way, but I was a little concerned about the weight (35g). Did you end up doing a 55g swap with one of the cheap ebay ones, and if you did, how did it go? Was it worth it? currently using a ducky cherry blue which is okay, but not super comfortable over long periods.
Thanks!

Not sure who you're responding to, but in my case yes: a I swapped the 35g sheet for a 55g sheet from eBay (S. Korean supplier, if memory serves). It wasn't very difficult (just remember to keep everything horizontal when screwing it back together) and was definitely worth it. The 35g sheet is so weak it is linear, the 55g sheet adds tactility. This can be heightened by removing the dental bands, though it will obviously change the sound.
-
Did anyone buy a set of the 55g domes and never use them? The seller on eBay says they are temporarily out of stock.
-
I wish the seller would get some 62g sheets in.

I was trying to source some 62g sheets to try, but looks like it's impossible to find. I think that they don't make them anymore.
Don't get me wrong, I love my 55g domes, and they feel amazing, but I would also like to try a 62g domes, just to compare the tactility.
-
I asked the seller when he thought he might have them back in stock. I'll post here when/if I get an update.
-
Not only are these back in stock but the seller now has a 65g option (!!)

Niceee, I don't know if I'd go that heavy. 55g already "feels" lot heavier than blues/blacks even tho they're pretty similar in weight.
65 would be tactile as ****, but probably very tiring for log typing.
-
i bought some of these a while back, i'm not really a fan. swaped them back out after about 10 minutes of typing.
they lack the "spring back" of the stock hhkb domes. i bought the 55g. almost mushier than stock.
but that being said, i had cut the sheets, and modified them to work inside the hhkb.
i'm sure they are great on the board they are intended for.

First of all, sorry for necroing this old thread.
This is a total misinformation. Either you misaligned the springs, or didn't cut the silicone sheet correctly.
I purchased two 55g silicone sheets. They are very slippery, totally not recommended for the inexperienced.
I had to reinstall and reopened my hhkb 5x, also screws and unscrews a couple more before all the keys feel uniform and tactile.
The "spring back" is very fast and powerful, about two or three times the power of the stock hhkb domes (it's SILICONE for christ's sake!) but definitely not as sharp and powerful as them BKE domes.
Installing the silicone sheet on RF87u took me 2x tries after cutting a new one, no real difficulties here. I'm surprised at how easy it is, perhaps due to its heavy plate.
Installing the silicone sheet on Novatouch, however, is a nightmare. First, the big holes between Function row and alphas. I have to cut it again since I reused the sheet from the previous RF87u. Next is the really difficult part. Novatouch pcb doesn't have holes to align with / for inserting the front case, unlike hhkb and RF. Since the silicone sheet itself is very slippery, a little 'nudge' can ruin the sheet alignment. Not to mention the amount of black and silver pcb screws, unscrewing and reinstalling is a real pain in the ***. Took me almost 20x before the 'perfect' uniformity, and I ended up spending all night reopening and reinstalling it.
The fun part is, while the stock lubed Nova 45g dome feels too weak for SA, this silicone 55g dome lifts those SA keycaps like a champ. The spring back is very satisfying (especially the spacebar), I highly recommend it for SA keycaps.
