Funky Frankenswitches

It was a few quick edits to a stock image :slightly_smiling_face:. It helps that there’s so many fruit-themed switches loll.

I have extra boba u4t stems, and I was thinking about putting them in moyu black housings. But i’m not so sure of the decision. Does anyone have any recommendations as far as housing choices go? I just want a nice switch to try out :smiley:

I tried this and liked it. It’s slightly more mild tactility-wise than a stock Moyu Black, but still a high-tactility switch. Nice and smooth. Higher-pitched sound-signature and harder bottom-out than a stock Boba U4T. Not different enough from the Moyu Black to suggest buying parts specifically to do this but if you already have them on-hand, hey, why not?

Ohh gotcha, Well I only have the stems on me (after making some sake switches). I’m trying to chase that deep sound profile, do you know of any housings that would get down and dirty (sound wise of course)

Off the top of my head, you might try something like a black nylon Cherry or Gateron bottom with either a Boba or Cream top. (Thinking of Deadpools, and also of some discussion I’ve seen about deepening sound with Cream tops.) Specifically chasing the deep sound isn’t something I’ve experimented with yet, personally - but Boba U4Ts are already pretty up there.

Generally, softer plastics tend to make deeper sounds, (definitely excluding UHMWPE tho) so see what you’ve got that seems on the softer side. The Moyu housings are some of the harder ones with the unusual choice of PBT as the material.

Soft plates like polycarb help too - and all my deepest keeb sound tests involve ABS MT3 caps. The blend they use appears to be softer than Signature Plastics’ that shows up in SA, giving them a nice, deep thock.

How’s ā€œthe less tactilityā€ explained? I’ve thought tactility is defined by the stem (and its legs) ?

The leaf also affects tactility as it can provide more or less resistance. Boba housings have particularly strong leaves.

Not OP, but I can tell you that the leaf (metal part inside the housing) also contributes significantly to how tactile a switch feels. That’s why a U4T stem has less tactility in an MX Brown housing, and an MX Brown stem gains more in a Boba housing, for example.

@iaman @Deadeye thanks for sharing :+1:t6:. New thing learned today.

I did try the brown stem in boba housing, it sounds kinda ā€˜wet’ to me. Also looks like tapiocaļ½ž

I’m actually going to try and build a few this week!

Wow, so I guess this thread is where all the fun stuff has been happening over the past week.

I’ve been trying to make ā€˜better Browns,’ because that’s where my efforts led recently, and one of the better recipes has been putting stock Pewter stems into a lubed Taro Ball housing.

I’ve only had limited use of my Taro Ball samples, but this seems to be the best one so far.

I used a 57 G 14mm TX spring and it made a really smooth Brown, although maybe it’s more like a tiny T1. Because the Pewter stem isn’t like MX Brown. More of a ā€˜bump and cliff’ than the more progressive Cherry stem.

I didn’t like stock Pewter switches, but Taro Ball seems to be a good housing for them. Prohibitively expensive switch here in Canada [Pewter gets hit with mad duties]. The Taro Ball housing remains extremely tight with Pewter stems, of course, so there’s no wobble.

So I actually made a couple of these just now.

This is indeed less tactile and obnoxious than regular BOX Silent Brown!

I’m so impressed by the stock BOX Cream switches, though! They’re smooth and punchy, and just the right weight, coming from Browns.

However, the BOX Creams make a high-pitched clacky noise on my cheap board.

The Cookies n’ Cream are much quieter, of course. A more-acceptable bottom-out than BOX Silent Brown, you’re not slamming as hard. Not as quiet as U4 Boba, though.

Kailh should make something like Cookies n’ Cream from the factory. Only weakness is spring crunch - I didn’t add any lube.

Hey Mr Frank. Just wanted to dubbel check with you. For the same feel in Heisenberg u could use Yellows or Kangaroos?

Afraid not - both have a leaf that isn’t as strong in terms of tactility. You’ll get a smooth, clacky switch - but it won’t be as tactile. The Blue Inks use a leaf meant for clickies, which also make for strong tactiles.

Ye, I suspected that. Thanks for the info. :+1:

We have a new tactility king, with a 90-120gf tactile bump (seems to vary) - NK Blueberry stems in Gazzew Boba housings:

Sample 1 (made with a 110gf Cherry MX Grey spring)

Sample 2 (made with a another Boba bottom, and a 90gf Cherry MX Clear spring - returned originally, but after disassembly and reassembly failed to return. The ā€œCopreā€ graph below was made with this one)

Note that this will likely kill the leaf from fatigue really quickly, since the size of the tactile bump is 3-4x the size on a Boba U4 (what it’s designed for), and the forces on the leaf are much higher as a result. Inconsistency and leaf damage are also pretty likely, as Sample #2 returned originally, but after taking it apart and reassembling it it no longer returned with the same spring, and the actuation moved down around 0.2mm than originally measured. That one also only had an ~90gf tactile bump compared to the ~120gf bump on sample 1.

With a TG3 ā€œCopreā€ rubber dome over it, over Sample 2 (~130gf tactile bump)

Hello again after a while. So, I got my dragonfruits and stem swapped them with the u4t stem, and it is way better than the original stem. It does make for a very odd switch, but there is way less spring ping and scratchiness. The odd part is that its very short travel and quite different from the original, but I really like it for gaming. It is a pretty good option when you are in a similar situation like me where you don’t like the dragonfruit switches and have some u4t/other long-legged stems you don’t use.

Wow! Very helpful.

I was about to take a Dragonfruit apart yesterday, so now I know what to put in it.

EDIT: BTW, Dragonfruit looks amazing when lit up on something like a smoky transparent KBD67 Lite. It would be a perfect switch for a hypothetical smoky KBD8X Lite.

Indeed! JWK bottom / U4T stem is probably the shortest travel full size MX combo I’ve tried so far. I have a small page dedicated to this combo on my website.
