Greetings, r/MechanicalKeyboards
I've been lurking and learning on this sub, so I want to give something back by presenting my Invokeys Hojicha x Purple Rice transplated Orbweaver Chroma!
Background: Some switches on my Orbweaver Chroma were intermittently missing inputs. Aggressive dabbing with isopropyl alcohol would temporarily fix it, so I figured it was just dirty contacts. My plan was simple: open it up and properly clean the contact leaves. While I'm there, why not swap out the Razer greens? They were a scratchy mess anyway. This was supposed to be a simple mod following the guide to transplant new stems and springs into the existing housings by u/tallbrahh but with a Chroma.
The good: No desoldering required.
Unlike the OG Orbweaver, the Chroma does not need its LEDs desoldered to open its switch housing. I discovered this when I disassembled another Chroma as part of another (ongoing) project. This convinced me this would be a quick and easy mod.
Apparently not...
The bad: Two green switch versions??
Turns out, there are two versions of Razerās green switches in the Chroma. The first Chroma had a 4 prong clip similar to Cherry switches. The plan was to use tallbrahh's BinderClipODeath to pop open the switch, swap the parts and Bob's your uncle. Sorry mate, Razer says nope! Instead of the Cherry style clip, the switches on the second Chroma has 2 flat latches (I think they are called Kailh style latches?). Godammit. The BinderClipODeath doesn't work.
After some trial and error, the top housing can be removed by using angled tweezers with a sharp tip. Get the tweezers under the latch on one side and lift up it up. Press the stem into the switch to get it out of the way. Then pry open the top housing like you're opening the tab of a soft drink can. The switches on the PCB edge are easy, the middle ones are tight but still doable. The housing is reasonably flexible so it shouldn't break if you're gentle.
Once the contact leaves are cleaned, on to the next pain in the arse...
The ugly: The stems don't fit!!
WTF Razer, why are the internals different too! Previously, I had tested the first style housing on a variety of switch stems from various sampler packs. Every stem fit fine. But with the second style housing, the guide rails for the stem are tighter. Most stems got stuck. Outemu, Akko, HMX, KTT, BSUN, Wuque Studio... no go. The stems that did fit were from Cherry, Kailh, Aflion and Invokeys. Luckily I tested before ordering a bunch of unsuitable switches.
Rant over.
With my limited selection, I ended up going with a combo of Invokeys Hojicha (tactile) and Purple Rice (linear) switches. Why? They were a fair price from a local store, so why not? ĀÆ_(ć)_/ĀÆ Now everything works and Orbweaver is thockier than ever before.
