【IC】Greatwall 65-Dragon lies high on hills, travels thousands miles long

Description

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.
