Build Guide
Update Sep 7: The Group Buy
The
GB launches on 9/20 at 8PM PST. It will run for one week, or
until we reach 40 units. I have no idea which will happen
first. Gonna set an MOQ of 25, though.
A full kit with
the TBR-Prime layout will go for $365 + PP fees and
shipping. Full kits with TBR-A and TBR-B layouts will run
for $390. If you instead choose to get a custom layout
(choosing a specific
left side,
top row, and
right side), that will be $465. You will also be able to order extra
PCBs and top cases - PCBs will be an extra $60, for the top
case it will be $150 for the Prime, $175 for the A or B, and
$250 for a custom.
I’ve already had
prototypes made for the TBR-A (top) and TBR-B (bottom)
layouts, but before we launch the GB, I wanted to do kind of a
second IC, so that I can nail down what exact configurations
would best suit most people. It’s just 4 questions, multiple
choice, should only take a minute. If you just want the
TBR-Prime layout, that’s locked in so you don’t need to
worry about filling this out.
IC Form 2
OP:
Keyboard design always
starts with the layout for me. For this board, I set out to
create something with the functionality of a 75% or TKL, but
with added features like a rotary encoder, numpad enter, and
macro keys, all in a tight and exceptionally usable package.
I ended up coming up with two primary approaches to this
goal, and I decided that I wanted both.
The Case
In the BattleTech universe, OmniMechs are unique for
their ability to quickly change their loadouts, with the
Timber Wolf being a fan favorite 75-tonner. This keyboard
follows a similar philosophy, with the ability to quickly
change between layouts on the same chassis.
To that
end, the Timber Wolf is top-mounted, allowing the entire top
piece and PCB to be quickly switched out with an alternate
layout. It is a plateless board, with the PCB affixed to the
top case in something reminiscent of a burger-mount, in an
attempt to foster a relaxed keyfeel with excellent
acoustics.
If quick-swapping doesn’t appeal to you (I
might be unique in wanting that feature), you may still be
interested in one of the possible layouts. The plan is to
allow people to pick any layout supported by the
PCB, and order a top case based on that layout. Hopefully
with no MOQs (though there will be downsides, such as added
cost). I also want to have a “Prime” configuration, though
(or maybe 2) based on what layout options are most popular
from this IC, and offer that layout at a lower price.
Hopefully this serves as the best of both worlds!
The
Timber Wolf will have an aluminum construction with no
weight, but it’s not exactly light - Fusion360 estimates it
at over 2.4KG for just the top and bottom case. It uses an
8° typing angle and 19.05mm switch spacing, and bumpon
strips.
Stylistically, I wanted to go for something in
the flavor of western mech designs, with an industrial look
and angular features rather than organic curves. I’m very
excited about how it turned out, and I hope you like the
look of the renders as much as I do, though colors are still
very TBD.
The Layouts
These four layouts are only a smattering of the
possibilities. Since I plan to allow people to choose their
own layout in the GB, I laid out the options in KLE, to give
you a preview of the ways you will be able to customize your
board. You can choose your own set-up for the
left-most column, the
top row & nav cluster, and the
right side. In total, there are 60 combinations (but much fewer that
I’d consider reasonable and expect people to actually use).
You can also make your own custom layout that builds on some
combination of those three sections and removes keys, but
you’d have to talk to me about that and we could design the
layout together (or throw something together and set it to
me).
While the layouts do all have their own flavor to
them, they mostly follow these tenants (most of it is
self-explanatory, but I love talking about this stuff).
-
1/3u Gaps: Having only a .25u gap between separate key areas never felt like quite enough to me, and I’ve kept the gaps between f-key clusters at a full .5u
-
Rotary Encoder: There are custom layout options that forgo this feature, but I truly love having one
-
Nav Cluster: Inventive nav cluster shapes are fun, but maintaining the original shape (more or less) will always be the best option
-
2u Delete: The PCB does support putting 2 1u keys in this area, but a 2u delete key (using a numpad + keycap) really feels great
-
Numpad Enter: Easily my favorite key on a keyboard, and I think its loss is the glaring issue I’ve had with TKLs - hitting numpad enter with my thumb has been a habit ingrained in me for my whole life, and I’ve talked to some others who feel the same way
-
Macro Column: Too useful for my workflow to give up dedicated macro keys, and this way all the artisan fans have a place to flex.
In addition to these wild customization options, the 60% block supports other, more normal options - both ISO and ANSI layouts, as well as split backspace, stepped caps, and a few bottom row options - focusing around compact versions of the standard bottom row, Tsangan, and WKL. -
