Description

Modulus

Hi everyone. I started designing this keyboard over a year ago to achieve a specific side profile I wanted. I’m a big fan of the basic wedge design in keyboards but I also wanted just a bit of added flair to still keep my design unique. After a lot of testing and redesigning I’m happy enough with the second prototype to revive this IC.

Form:https://forms.gle/LCLxwDDpfosoev1e6

Details

- Top Mount Aluminum Case
- 6 Degree Typing Angle
- ≈17.8mm front height
- Brass weight

The board was designed to use PCBs with ports centered between the “esc” and “1” keys such as the ANC-60 and WT60.

Renders

The plate is top-mounted with 4 mounting points. The cutout around the spacebar is inspired by Windeh's Omega 60 and has been further stylized to look like a linked list.

Prototype Photos

The second prototype features revisions to the port and seam to better achieve the aesthetic I was aiming for. The underside has also been changed to an engraving (infilled) paired with a through weight which depicts a binary search tree where the root node is accented by the brass. The final board design currently differs slightly from this proto by featuring 4 case screws and the redesigned plate shown in the renders. The PCB in the build is an ANC-60 from Cannonkeys.

Group Buy Plans

- Price is TBD but my target is ≈350 USD at a decently sized MOQ (≈80 units) with vendor involvement
- I'm leaning towards offering WK and WKL layout options based on current IC feedback
- I'm quite happy with the gray and red anodization on my prototypes so they will likely be the options for the group buy. Feel free to suggest colors on the form since I may change my mind or find it feasible to add more color options. Pictures of the gray ano on prototype 1: https://imgur.com/a/FcqEoeV
- I plan on including a PCB in the kit

Extra Info

Inspiration

The Modulus is a programming-themed keyboard. The binary search tree and linked list are both common data structures and the name of the board is a reference to modulo operations.

Fitment and Design

The board is designed with a tiny bit of extra tolerance in the two rear corners of the board between the top and bottom halves of the case. This is to ensure that there is only one plane of contact between the halves when they are fitted together. Besides the complexity of the seam, the design of this board follows a simple top-mounted wedge.
