Hello everyone, We at ClickClack.io are thrilled to introduce our new brand, Kochi. Inspired by the joy of delicious roasted chicken wings, Kochi aims to create affordable computer products that bring simple pleasures to everyday life. Today, we proudly unveil Kochi’s debut product, the Hummingbird68. This keyboard harnesses the power of magnetic switches to emulate the speed of a hummingbird in typing experience. Offering unmatched value at the most competitive price among comparable products, the Hummingbird68 is designed to be "The Magnetic Keyboard for Everyone," combining exceptional performance with affordability.

Design

The Hummingbird68 pursues a futuristic design aesthetic, with overall lines cut like diamonds, exuding modernity. After several rounds of prototyping, we decided to use a single block of aluminum and employ CNC machining technology to ensure continuous and smooth overall lines. The edges of the entire machine are slightly chamfered, presenting and restoring the overall design perfectly.

On the bottom, features a hummingbird pattern engraved in the center, symbolizing agility and freedom. Kochi's first product chooses the hummingbird as its theme, designed specifically for Esports. The agility of the hummingbird and the high-speed triggering of the magnetic switch complement each other. The nimble characteristics of the hummingbird and the unique multi-stage triggering of the magnetic switch make the Hummingbird68 your most reliable companion in the gaming world.

Colorways

Kochi spared no expense in achieving the perfect appearance, opting for the silky smooth anodized finish (220-grade, compare to 150-grade mostly used), with a total of five anodized colors:

HE (Magnetic) Internal

The structure of this keyboard is centered around delivering best result from HE Switches. The mounting for securing the keyboard case takes into consideration structural aspects to avoid the phenomenon of accidental triggering caused by elastic deformation, especially in high-sensitivity usage scenarios. The pin of the switch is designed to be more firmly installed on the PCB.

We name this HE Switch "Elven Blink". We've gone the extra mile by redeveloping our magnetic switches to provide a tactile feel more akin to traditional mechanical switches, making it easier for adoption.

Specifications of Elven Blink HE Switch:

- Typing Style: Linear
- Initial Force: 37±5gf
- Bottom-out force: 50gf
- Total Travel: 3.85±0.2mm
- Pre Travel: Freely setting
- Pre-Lubed: Yes
- Spring: 18mm customized spring
- Lifetime: 100 million times keystrokes

PCB Design

The PCB adopts a high-performance RISC-V MCU with a clock frequency of up to 144MHz, enabling rapid key scanning and algorithm processing. The chip comes with a 480MHz high-speed USB PHY, capable of achieving up to an 8000Hz polling rate. This solution achieves a full key scan time as low as 250us. It offers 50+ RGB lighting effects, allowing customizable gaming lighting. It supports custom key mapping, advanced macro commands, and other functions. With an average accuracy of <0.05mm, the entire key travel can be adjusted from 0.1mm to 4.0mm. The PCB Management software provides comprehensive keyboard management, allowing users to configure key travel, lighting mode effects/brightness/speed, advanced functions with online firmware upgrades.
