Greetings guys, this is Creatkeebs,
After completing
the romantic Thera75 in the Mediterranean and the biting
Glacier80 in the North Atlantic, this time we set our eyes
on the Chinese land: among countless images that represent
the profound and long-standing Chinese culture, we finally
chose the Great Wall as the theme this time. Here is the IC
of our next creation, the Greatwall 65.
Introduction
The Great Wall is the masterpiece of the Qin Dynasty, which
was used as the base to develop the Silk Road during the Han
Dynasty, and now the Great Wall is known worldwide as one of
the wonders of Chinese civilization.
For more than a
thousand years, the Great Wall has been perched on mountains
and lands. This time we have incorporated the elements of
the Great Wall into the work：The outermost layer of the kit
is carved out in the shape of a battlement, which spreads
along with the alignment of the bottom weight and rises at
the two corners, creating the imagery of two beacon towers.
At the bottom of the board, the weight extends to
occupy the upper space and still retaining the curvature of
the mountains in the division with the bottom case. In the
middle of the bottom case, the words “長城” in Chinese Qin
dynasty character reside on the weight and the bottom shell
respectively, indicating the era when the Great Wall was
formally built.
Internal Structure
On Greatwall 65, we continue to use the same pcb-leaf-spring
structure that we have been using to support plate-less
structures and have made some improvements over the previous
ones.
We changed the PCB cutting method, through the
horizontal and vertical flex-cuts to divide each switch into
a unit. At the same time, we use black core material for the
PCB, which is tougher to improve the typing consistency and
sound performance, and can ensure sufficient service life
when the PCB is substantially deformed, even in plate-less
build 1.2mm thickness will be able to meet the strength
requirements.
We also changed the material of the poron
gaskets to rubber socket, which can greatly facilitate the
installation process and also avoid the problems caused by
the stretching poron gaskets during installation. We still
retain the design of compatible with the installation
without steel and steel, you can decide to build this
plate-less or plated by replacing the 1.5mm poron foam and
1.5mm plate.

Color options
We provide 8 different colors with a variety of weights this time, from the classic black, white, gray to the ancient Chinese flavor of vine green and ochre brown and so on. Except e-white case, all the others are anodized color. The weight includes e-lucency brass, PVD frosted gray stainless steel, laser engraving and chroma PVD.
Wrist rest and Keycaps
The wrist rest has two versions: PC + Alu and Walnut wood + Alu, the appearance continues the design style of the board, retaining the winding Great Wall arc and “昌盛” (Prosperity) engraved on the top of the hand rest, and insert Alu strip with Chinese traditional pattern.
The keycaps, of course, can not be left behind.
Inspired by the Great Wall, we integrated a variety of
elements of the Great Wall, such as beacon, gatehouse, etc.
into the keycaps design, and the classic black and red color
scheme. We also communicate with the OEM and strive to a
more affordable price for the whole set keycaps.
