Hi geekhack,
I’m Windeh, a relative new member
of the community.
After a few frustrating attempts at
sniper-submitting google forms & raffling GB spot from
popular designers and failing, I asked myself, why not just
design a keyboard myself?
I thought about what would make MY perfect keyboard?
With a few ideas in mind, I set about downloading Fusion
360.
.
.
.
A couple of YouTube Tutorials
later, shapes resembling a rectangular block started to
form
First, let me highlight some of the more unique
features of my design;
Mounting.
As per the title of this IC, the plate is Sandwiched
between O-Rings, with no part of the plate in contact with
either the casing or the screw, creating a true Floating
design. I call this mounting method O-ring-Sandwich-Floating
mount. You heard it here first.
Unlike traditional
“Gasket” mount, where most contact between the gasket &
the plate is desired together with high clamping force to
dampen all vibrations, this mounting method more closely
resembles a xylophone, with minimal contact surface and
added isolation between the plate and the rest of the
keyboard. The design when tightened, does not clamp directly
onto the plate through the O-Ring, but stops when the O-Ring
posts on the top & bottom of the case meet. Depending on
the Durometer (hardness) of the O-Ring, the plate will
experience a stronger or lighter clamping force, therefore
change the way it is allowed to resonates (and to a smaller
degree, feel). By simply changing the hardness of the
O-Ring, you can easily tune the resonance & tone of the
plate.
Why the O-Ring Cutout?
Proper application of O-Rings requires that they are
supported on both sides perpendicular to the force exerted.
Without the support of the side wall created by the cutout,
the O-Ring would be easily squashed, causing rapid
deformation & deterioration of the material, while not
providing enough pressure onto the plate. The O-Ring would
start to harden & crack, altering the acoustics &
feel of the keyboard with time, and possibly cause looseness
of the plate.
There is, in my opinion, no alternative
method to apply the O-Ring in this application.
Floating?
There is a minimum of 0.5mm gap between the plate
& any hard surface of the case.
Spacebar MEME cut.
The first time finished building my TX60, I
immediately noticed that with such a rigid sandwich mount,
the spacebar makes a loud KUNK every time it bottoms out. I
know there are mods out there that addresses this feature,
however I wanted to try to address this from the keyboard
design side, and tried to reduce the rigidity of the
mounting post closest to the spacebar, to give it some flex
where it is needed the most.
ANSI layout only.
After having to deal with a wonky \ key on an
universal layout, I said No more.
Compatibility with existing PCBs on the market.
Not gonna lie. I have no knowledge on PCB design and
no friends with that skill set. I don’t want to be tied to a
proprietary PCB that youre SOL when it dies down the road. I
will not force RGB, Hot Swap Sockets, Bluetooth, or JigOn
down your throat. You choose your poison.
Hate tall fronts?
This one is under 20mm.
Two Very different chassis designs and focus, same plate
& top.
Because choices.
I think I have gone on long
enough
Let me introduce the Reflex and Paradox 60%
Keyboards;
Reflex : The name refers to
the reflex port on a speaker system. I heard people in the
community are big on sounds, so I took a literal approach,
and thought of the PCB & Plate as the diaphragm on a
loudspeaker, then proceeded to designed a reflex port for
all that juicy auditory goodness to escape out the bottom of
the case. And the weight. You can’t forget about the
weight.
Next up, its the Paradox :
The
MK Community is a hard place to be an enthusiast. You want
to throw your money at something, but it is thrown back at
your face in 41 seconds.
Not gonna pretend that the Paradox didnt take
inspiration from other keyboards. But with the 60% layout,
plate mounting method, weight quantity & design,
material and all of the above, I believe there are enough
uniqueness that there is a place for the Paradox to exist in
the MK community.
Now, some details.
-
Case: Standard configuration in 6063 aluminium, optional upgrade to 7075-T6 aluminium
-
Weight: Sandblasted/Polished Brass finish options. Clear coating option for sandblasted only, as coating does not adhere well to polished brass
-
Screws: YFS Grade 12.9 Alloy Steel Hex Screw
-
O-Rings: Will include a few different hardness/material O-Rings
-
Colour: For 6063 Aluminium - Normal Anodizing in Black, Dark Grey, Deep Red, Royal Blue, Silver, Rose Gold (maybe). For 7075-T6 Aluminium - Hard Anodize in Black only. All anodizing in Matt finish only.
-
Plate: Standard kit with Brass plate, optional Aluminium & Brass Plate extras, Sandblasted
-
Layout: 60% ANSI WK/WKL with split right shift and optional split backspace & stepped caps lock
-
Quantity: 30 total spots
-
Timeline: Aiming at December / January GB
-
Design: Both Paradox & Reflex will be made, 15 sets of each
-
GB Pricing (All pricing in USD):*
-
NO PCB INCLUDED IN THIS GB!
-
$490 for base kit includes 6063 Case Top (Standard or WKL) & Case Bottom in normal anodizing, Clear Coated / Raw Sandblasted Brass Weight and Raw Sandblasted Brass Plate
-
Optional extras:*
-
$35 for upgrading to 7075-T6 Case Top & Bottom in Matt Black Hard Coat Anodizing.
-
$20 for Polished Brass Weight (Polished on exterior sides only, Raw).
-
Extra Plates in Raw Sandblasted Brass ($50) / Sandblasted Aluminium (Anodized Deep Red - $60)
As I said at the beginning of the GB, the keyboard is mainly designed to be MY endgame. If a group buy is happening, it will be a very small quantity to dip my toe in the water and have a feel of what I’m getting myself into.
Feel free to leave comments below, and I will reply when I can.
