HMKB - 60BW

PCB
Promenade

I love the Boardwalk. It is still my favorite keyboard concept after 10 years in this hobby, and one of the major reasons I got into ortholinear. One of the reasons I made copy was that I had ordered so many PCBs from MKUltra that at some point it would become more cost effective for me to just manufacture my own for personal use, but I also wanted some additional features. I prefer 1.5u center mods, so I would end up mill-maxing the solder version instead of using the Professional 2 version of the Boardwalk. I also found that I prefer 3u spacebars to 2u and wanted stab holes instead of making custom plates. With all of these gummy o-ring 60% boards, it seemed logical to add o-ring cuts to the board, along with a JST connector. So I made all these changes and called it the Promenade as a nod to the Boardwalk.

Let me know what you think!

I am also in the middle of designing a solder version that would have way more layouts and a bunch of encoder support.

*Solder version layouts (still being designed)

GB Details
Estimated run window: Late September~October
Estimated delivery: Q1 2024
Estimated price: $50~$60
*The solder version is still being designed, and will likely not be ready for GB until end of the year.


For years now, MKUltra has kept the Boardwalk in stock and available, but as he is closing shop and the Boardwalk PCBs are no longer in stock, the future of the Boardwalk is currently unknown (at least to me). So I have decide to run this IC to see if there is enough demand for me to order a batch as a GB. Assuming there is interest, I will run it alongside the TKL version, the Kousa TKL.

i'm in. let's go!

Definitely in. Can't wait!

Great. I am in for one.
Will be a good add-on for the Heavy Metal Keyboard.

I'm in as well. My only wish is for a better MCU than in the original Boardwalk. It didn't have enough memory. RP2040?

I am currently working on the design for the solder version, which will use an RP2040. As the pictured hotswap version is already finished, I really don't want to take the time to remake it with a different MCU.

It seems that people are pretty divided on 1u vs 1.5u center column, so I will offer both. Please be aware that if you are using 5 pin switches with the 1u version you will need to clip a leg on two of the switches.

Details on GB coming soon.

Hi everyone,


I would like to give a small update on the status of the IC and GB now that we have reached the end of October. My initial plan was to start the GB at the beginning of October, but my employer informed me in September that I would probably be sent overseas for about a month sometime between October and March. The dates were finally decided, and I will be traveling for most of November and the first half of December. I didn’t want to run into a situation where I wouldn’t have time to deal with GB related tasks while in another country, so I have held off on doing anything. I am still working on the RP2040 solder version, and will continue to do so while I am on my business trip, time permitting. I plan to adjust the gerbers to make the current hotswap version Bakeneko v3 compatible over the next few weeks. The plan for now is to run a GB for the current hotswap version with 1u and 1.5u center columns offered and a Bakeneko V3 compatible version offered as options. It will probably be a few months before the solder version is ready for production, but I am hoping to run that one around February 2024.


Thanks to the IC I have a more accurate headcount, so I will work on getting more definitive pricing. Hopefully I will have another update before I leave on my trip. Thank you for your patience.

I have never posted to GH before, I honestly had forgotten that I even had an account, as I almost always just lurk.

But I just have to express how unbelievably excited this makes me.  My daily driver is a Boardwalk and I had always planned to get a second one at some point, and then MKUltra shut down and I thought I was **** outa luck.

This is honestly so amazing, I really, really, REALLY hope that this comes to fruition.

Thank you for the enthusiasm! I too love the Boardwalk and bought probably 5 Boardwalk pcbs from MKUltra over the years. I am planning to open the groupbuy before the end of the year.

It's been a while since I logged in on Geekhack as well. I had purchased one or two ergo keycap kits with boardwalk in mind but postponed the project until I realised mkultra is closing. This is what I've been waiting for. Thanks Narf!

I'm looking for 1u center column, preferably with hotswap sockets. Hoping EU shipping (Poland) won't be a problem. Rest of the things don't matter that much to me.

Keep us posted!

I was always intrigued by the boardwalk but never got round to getting one. This is very tempting. Anyone got any recommendations for some reasonably priced Cherry profile caps? I can always take the alphas from one of my sets but I'm not sure where to get the mods...

I love this,  I need this, this is a perfect layout, please make it happen (In for a tsangan bottom row to use with o-ring inside a unikorn-like case)
