POLYGON 65% - Prototype update 06-16-2021 - Prototype 3 has arrived!

Long time no update

Almost 7 months has passed since i posted the initial IC here, and boy has things progressed. Time has been flying delays have been encountered, but Polygon has matured a lot in the meantime. The third prototype is on its way, all the colors have been revised, and the case has been completely redesigned from the bottom up between prototype 1 and 2, to meet my quality standards. It is now about time i show you the prototypes I have, my new website and some various other bits of information I'd like to share.

Description




1 – Custom knob

A custom knob for the rotary encoder. It has a diameter of 30 mm.
It'll be available in any of the available colors and as a brass version.



2 – The top

The top features a 3mm chamfer alle the way around the upper edge.
It has been given a slight fillet, to increase comfort.


3 – The mounting system

The mounting system uses four stainless steel dowel pins, and four linear low-friction bearings provide a precise fit of the plate in the case.
It also acts a rail allowing you to tune the typing feel by changing the gaskets for harder or softer ones or use thicker gaskets on one side or the other.


4 – The gaskets

The Polygon uses 12 molded gaskets. Not having the gasket surround the entire plate, will allow the plate to resonate slightly, and use the plate to create Polygons sounds signature.
The gaskets will be replaceable and cutting files will be made available if you want to experiment with gaskets.


5 – The bottom

The bottom houses the USB-C daughterboard and features a POLYGON engraving and my logo.
During assembly, the top and the bottom comes together to a form a single unit, the top and bottom is then fastened to the slope.
Six low-profile bolts are used to secure top-bottom unit to the slope.

6 – The weight

The weight is fastened to the slope, through the left and right acoustic chambers.
It weighs in at around 1.1 kg (2.86lbs). The sharp edges of the weight is what gives Polygon its name.


7 – The slope

The slope has 3 rectangular cutouts, used as acoustic chambers and will provide a unique sound signature.
The chambers can be foamed and tuned to your likings, using the provided cuttings-files. You will also have the option to choose my preferred dampening solution.
