Muramasa - The Ultimate Longboi / XT-FRL+Numpad



Since getting into prebuilt mechanical keyboards, I have always had a fondness for big boi keyboards - such as full sizes or TKLs.

Coming into the hobby, I have had my fair share of big boards - tons of TKLs - but I always thought: Can I go even bigger?

Introducing the Muramasa - a XT-FRL + numpad longboi.
^{(PS this is also part of an attempt to get my colleague into mech keyboards, since he won't shut up about how he "needs a numpad".)}

IC FORM

Specs
- 8 degree angle
- Adjusted front height of 20mm
- Materials: 6063 Aluminum (top&bottom case), Brass/SS(weight)
- Top mount, two piece plate (considering 5052 Aluminum / PC / FR4)
- Three piece brass weight (will look into SS weights)
- 3333g unbuilt
- Bezels: 8mm(top/down), 5mm(left/right)

Layout
- Supports: full/split backspace, full/split right shift, full/split left shift, ISO, ANSI, 7u/6.25u bottom row, and different numpads




Gallery
- Only renders for now
- Am still deciding between two versions of the side profile (one with elliptical cut/one without)














Mounting method
- Top mount with separate plates for the 60%+XT area and nav cluster+numpad.
- I wanted a softer typing experience & inspired by the glare, I thought this would be an interesting mounting method.
- Leaf spring / Half plate / Connected(as opposed to the aforementioned split) plate are things that I want to try as well.






What's next?
- This post is used to gauge the interest of the community, but either way I will be getting prototypes made. Expect updates to come in the future.
- I plan to open source this project at some point, after I make the prototype and make sure I iron out the details.
- Going forward, a GB maybe possible, or even an internals(PCB+plate) GB (for people who want to machine their own)
- I've done some preliminary budgeting for this project. If there is a GB, I'm aiming for something like $480 @ 100MOQ / $650 @ 25MOQ.

Thank you!


Update
- Thanks for all the kind words, including keyboard friends who have filled out the IC form.
- It seems like the original quote I received for 100MOQ is not viable(which I thought was a stretch from the beginning anyways giggle)
- Hence I will be looking at other manufacturers, hopefully ones that can do 25MOQ/50MOQ at a reasonable price. If y'all know anybody, do please hit me up
- When I open source the project, I will also include version with no weights to hopefully help with cost saving.

Very cool! Have you considered making the board longer?

Fantastic! I was curious what could become longer than my W1 or Calliope, and now I finally have an answer! Lovely design

For some reason, I have an intense urge to join this when it goes to GB ^^

cool! why?

What a happy ending and fitting for pride month. 

Very cool! Have you considered making the board longer?

Yes

This board is a perfect excuse to get a bigger desk. I cannot wait to see the protos!

I’m hyped as well!!! Thinking of ways to bring cost down atm, for the benefit of people who might wanna machine themselves as well.

Now this is what I call long boi, interesting project.

This project is so good, especially open sourcing the project, very cool GLWIC!

It's been a while since a new board IC has drawn my attention, WELL DONE! 
PS: Please consider long spacebar support (10u) for this long boi

oh this is incredible, 10/10 for l o n g b o i

This is freaking awesome

This looks awesome! WKL would seal the deal for me! GLWIC 

Thanks for all the kind words! BTW, WKL is coming……

this brings all the big pp's to the yard. i'm in. wkl a must. you're a wizard.
