[IC] Martingale

---------------------------------------------------------------------------------------------------------------------------------
The Martingale is a PCB top-mounted, 60-percent keyboard designed to be comfortable to type on and relatively affordable, and the aim is to maintain quality standards often found in much higher end boards in the hobby. The construction of the case is simple, and consists of three parts: Top and bottom case, and a daughterboard mounting accent. Nearly every single design element is functional in purpose, with the exception of the side profile and bezel sizes.

---------------------------------------------------------------------------------------------------------------------------------
Key features and specifications:

Please refer to the image below.
284834-1

---------------------------------------------------------------------------------------------------------------------------------
Prototyping:

As of now, the board has had four prototypes over two rounds of prototyping, with the fifth and final prototype on its way to me. All images of the prototypes can be found in the following Imgur link: https://imgur.com/a/1r6CReq (the green prototype is the most recent one). Also including three images below.
284740-2 284742-3 284738-4


---------------------------------------------------------------------------------------------------------------------------------
Inspirations:

1) The internal stepped geometry in the bottom case is inspired from the Bias TKL with the permission of the designer himself (Baionwave^TM lets go!). I found it useful to implement low typing angle and front height while also retaining some heft, leaving space for the pcb to flex without bottoming out.
2) The side profile is inspired from the now famous Matrix 8xv2.0 and 6xv2.0 series of boards.


---------------------------------------------------------------------------------------------------------------------------------
Group buy info: (Please scroll for latest updated GB info)

1) Price target: $250 + shipping and taxes (would be about $290-310 including VAT for most countries.). Will include carrying case.
Best case: sub 250 USD including carrying case. Worst case: sub 300 USD excluding carrying case. Looking at around 300 USD (slightly more with carrying case).
Please understand that these are only estimates from quotes I have received from manufacturers with some educated guesses made. The actual price could be less or more depending on number of units. I will update this when I have more information!


2) Vendors: None as of now. Will be approaching vendors soon! ClickClack.io will be the global vendor

3) GB Date: Depends on how talks with vendors go, but targeting Q3 2022. GB month will be December 2022


---------------------------------------------------------------------------------------------------------------------------------
Questions?

1) Why are you calling this the Martingale?
I have decided to name my boards on concepts from probability theory. Why? Those who know, know :simoneyes:

2) You say this is plateless, but will a plate be included anyway?
I plan to include an Alu 5052 plate by default.

3) What about plate files?
Any tray mount/gummy o-ring mount plate like the ones in your Tofus, Bakenekos, and Unikorns will be compatible with the board. So there is not much point in providing plate files since it has no mounting points,

4) Will the board be compatible with standard PCBs?
No. The pcb has mounting tabs which are specific to the Martingale, so no aftermarket pcb will be compatible. However, I will consider releasing gerber files of a modified Bakeneko pcb with the mounting tabs added and other minor modifications made (the GB itself will use a proprietary PCB, unless there is a change of plans for some unknown reason).

5) Do you have any experience running group buys before, or any manufacturing experience?
I have never run a group buy before, and this is my first Interest Check! However I have designed and manufactured many an engineering product back in undergrad (automotive suspensions, chassis, etc.). This my first time designing parts where aesthetics are as important as functionality, and it has been a learning experience!

---------------------------------------------------------------------------------------------------------------------------------
Thanks:

Maelk has been helping me with the pcb. Thanks Maelk!
This would not have been possible without the support of some of the lovely folk in the Indian Mechanical Keyboard Community (IMKC), and many more scattered across the world of overpriced rectangles. You guys know who you are! Thanks!

Would love to see a large rear weight given this is one of few pcb mount 60ís at least within recent memory, but either way looks like solid project. Good luck with it!

Thanks everyone for the support!

Also realized that Iím an idiot and didnt upload layouts. Will do it over the weekend, but you can expect the typical 60% fare. I really wanted to do the og HHKB layout with the larger right hand side blocker, but it likely wont happen. Will mostly include just the regular HHKB option along with WK and WKL.

Also regarding sound tests, they will take some time but I wanna make sure its a representative sound test. I personally do not have a recording setup of any sort, but will ask some friends to record it! Wont happen before end of month though.

Thanks again!!

I see you have poured a lot of effort into this. Everything looks great.
I don't see you mention which case colors will be available during the groupbuy, therefore I hope a nice, light shade of grey/blue/lilac makes it ;D
Hope there will be an Asia/South East Asia vendor.
GLWIC!

Looks really nice, I love that green. I much prefer ceneterd usb on 60%, i think having it on either side really messed up the symmetry.
I'm not really a topmount guy, I've also never tried plateless. At the target price i'd be down to try :thumb: GLWIC

You are right about no mention of colours, and its simply because I havent decided them yet. Its still an IC so the process of testing out colours with the manu is not yet done. I will be updating the IC soon with a form asking colour, layout preferences etc.

Also vendors TBD 😭. Everything is TBD and will update as soon as I have more information!

From the IC form, it seems like a lot of people like PP plates! Will likely try out a standard 60% PP plate and see what its like.

Not a 60% user but had to leave a comment for the awesome naming. Maybe consider a Supermartingale in TKL in the future.   :thumb:

So the keyboard is named after the guy who invented probability? I guess that makes sense.

not a fan of the big chamfers on the keycap side, but aside from this the specs are perfect imo, will watch and see how this project goes. GL!  :thumb:

Looking good so far and curious to see what the color choices end up being. I feel lighter colors would look good on this board for some reason.
