    Design Concept

    The designers of CKW studio want to create a keyboard with more customize possibilities, simple and elegant looking, so they bring us

    Three mounting ways in one keyboard

    CKW 80 can be made with 3 mounting ways: Plateless/ Gasket/ Top Mount.

     The method to realize it is to use a specially designed middle frame. Turn over the middle frame to clamp PCB or plate with gaskets, so that we are able to switch between plateless and plate gasket. If you like top mount, you can even change it into top mount. We designed the screw holes for the top on plates, and add additional gaskets for the top mount. 
    【Note: For Gasket Mount/Top Mount, the PCB ear needs to be removed (it’s irreversible)】

    (1)Plateless → Gasket (By turning over the middle frame), below shows how it works.

    (2)Top mount (The plates have screws holes for top mount)

    Interchangeable type-c connector and decoration

    Someone like left type-c and someone like right one, so we designed a type-c connector which can place left or right as you like. Interchangeable type-c enables you to design your desk layout freer. 

    Appearance Design

    As the studio manager's name is Chain Smoker, and we want to make the keyboard more distinctive, so we add some cigarette elements on it.

    There are some cigarette elements on the back, and we use diamond cut to indicate a lit cigarette, which makes the back simple and exquisite. What’s more, we change the "CKW" letters on the top case to light bar which resembles a cigarette after many modifications. In order to keep consistent with the lit cigarette on the back, we made a sinking treatment on the light bar top to imitate the ash after igniting.  

     Although we used some cigarette elements, we do not encourage smoking, so we engraved “ Smoking is harmful to health” inside the bottom case for reminding.

    Design details:

    (1) We engrave a border in order to make the gap distances below look same 

    (2)The corners are made with G2 curvature round angle ( similar to iPhone’s angle) for more comfortable and smooth touch feeling.

    Upgraded PCB Specifications

    In order to provide more customize possibilities to you, we think a lot about PCB design: 

    • Hotswap PCB with various layouts: TKL/WKL, both support ANSI / ISO
    • Leave the solder place for knob on F13 considering lots of people like the knob
    • Upgrade to Flex-cut black core Bluetooth Hotswap/ Solder PCB, which is better in quality than the ordinary one

    Elegant Desgin and Silky Touching Feel

    Just like the name of the keyboard, its design inspiration comes from the streamlined shape of the dolphin's forehead bulge and the gradual shrinking shape of the tail. The special curve design makes the keyboard look simple and elegant.

    Besides, it provides you the smooth silky touching feel with better case craft, feel like touching the dolphin skin. 

    As lovely dolphins are friends of human beings and always accompany us at sea, we want to make Dolphins75 more user-friendly in daily life, just like the dolphin accompany you all the time.

    Better Typing Consistency

    In order to improve the typing consistency for all keys, we use the gasket - foam instead of gasket to keep every single key the same typing feel.

    What's more, it makes the build process simpler and easier by conbining the gaskets and foam.

    Add on Dolphin Badge

    Here we have two colors of lovely dolphin PVD badge to add on for F13 key.
