Frusta Fundamental
Modularized 65% keyboard with multiple mounting systems
Designed by G14D from PicoLab, Hong Kong

Background

Almond! Almond! This is G14D from Hong Kong!
Frusta is a project that I started since June 2020, I designed a number pad (Frusta Experimental) with the idea of assembling six frustums together, the same design language is now implemented to a 65% keyboard.

Frusta Experimental
As I encountered several issues with the original design, the development of the number pad was suspended. The major problem of the number pad is that it requires extremely high CNC accuracy, else there will be a significant gap between the frustums. The difficulty in developing this project will be mentioned later.
The IC of Frusta Experimental I posted in September last year

Design Inspirations
The appearance of the current top frustum is inspired by NZXT H1, and the modularization design is inspired by the Cool Master Mastercase series.

Features

  • 65% layout by default, but can change to 60% by replacing the top frustum, plate and PCB only, cost less than $100

  • Support gasket mount, top mount and plateless tray mount

  • Switch between different mounting systems smoothly, no extra part is required

  • Comes with 7-degree typing angle by default, bottom frustum with different typing angles will be manufactured in the future

  • The PCB supports QMK, VIA and also support firmware and GUI editor developed by PicoLab

  • Top cover(frustums) are sold separately, down to $40 for each

  • No weight, it’s under the bottom, you cannot see sh!t when typing, it’s useless

  • Well-known project in the Hong Kong Mechanical Keyboard community

  • Modulazation*
    I often found inspirations from PC cases, the MasterCase series made by Cooler Master is the first PC case of mine, I bought it when I was 16. The reason that I’m mentioned it is that the MasterCase series provide a noticeable modularization experience. Buyers get a lot of freedoms to modify the position of different components inside the case. I would like to provide the same modularization experience to you guys using Frusta and I believe that will be the future of DIY mechanical keyboards.

    I want to design a keyboard that can be modified, can be upgraded using as fewer parts as it needs.
    So one of the signatures of Frusta Fundamental is that it switches smoothly between multiple mounting systems and no additional parts are needed during this process. I designed some removable mounting columns which make the keyboard compatible with tray mount. Besides, a tiny square was cut out on the right-up corner of the middle frame, It’s reserved for an encoder.

  • Kitting*
    Although the design had slightly changed, the middle frame is no longer assembled by 4 frustums. The concept of modulization remains. To achieve modulization, different parts of the keyboard are sold separately.

  • There will be 50-100 instock unit worldwide in early March Mid April 2021*
    b] The store of PicoLab will be within MAY 2021. However, the ISS units will be delayed for a while as we must ensure the quality
    There’re some spot reversed for PicoLab, and will sell in April
    Other vendors have the right to open pre-orders for these instock units.
    The Estimated GB date is after the instock sales[/size][/color][/b]

  • Prototypes*
    At the moment you saw this IC, I had make 3 rounds of prototypes for Frusta Fundamental already If prototypes for Frusta Experimental is counted as well, I made 5 rounds of prototypes in total.
    /No filters are added on the photos/

  • Frusta Fundamental Prototpye R1*

  • Difference between this and Fursta Experimental prototype: The middle frame merged together

  • manufacture date: Nov 2020

  • Mouting systems: top mount, tray mount

  • Material: full brass, heavy AF

  • Surface finishing: Cerakote, clear coat on top and bottom, midnight bronze on middle

  • Apperance: Poor

  • Issues: The cut out for USB is too tight

  • Status: abandoned, issue fixed



    Also Fundamental R1, anodized and with some prototypes from Experimental R2

  • The middle frame of this one is Dark grey*

  • Frusta Fundamental Prototype R2*

  • Difference between this and the last prototype: the USB hole becomes bigger

  • manufacture date: Dec 2020

  • Mouting systems: top mount, tray mount

  • Material: Aluminium case, brass plate

  • Surface finishing: Cerakote, sunflower on top and bottom, snow-white on middle

  • Apperance: average, but I don’t think is good enough

  • Issues: the CNC tolerance is poor, it use 3-axis CNC, there are still gaps between parts, the sound can get better too

  • Status: abandoned, issue fiexed


  • The gap between bottom and middle has been FIXED in R3 already*
    (Photo credits to Bokkey)

  • Frusta Fundamental Prototype R3*

  • Difference between this and the last prototype:

  • Add gasket mount support

  • Reduced the hollow sound

  • Changed to 4-axis CNC

  • Changed the tray mounting columns from fixed to removable which makes the board compatible with gasket

  • manufacture date: Jan 2021

  • Mouting systems: gasket mount top mount, tray mount

  • Questions You May Ask*
    Quote So…you guys may get confused why did I choose to work alone for such a long period?
    Well, there are different sort of people in this world. I’m that sort of person who works hard in the corner, focus on my target, and expose my work to the community only when I feel that I’m well prepared. let’s use League of Legends as an example, I’m that sort of top laner who play Nasus and farm till 30 mins, with over 1k stacks and win the game in one go.

  • Altho I main Jax and Swain, and seldom play Nasus lmao*
    Anyway, this is not a rush sh!t, I prepare this project for over half a year. I made 3 rounds of prototypes, calculates all the costs, dealt with vendors, started manufacturing the instock units and finally starts this IC thread. I didn’t gain attention during the early stages of this project, from the moment I started an IC thread, I take responsibilities. Not saying that I don’t like to carry responsibilities, I simply hate the feeling of working under pressure.
    If anything goes unexpected during the early stage (There’re lots of issues found in the prototype phase indeed), then I must work harder to fix it and try to complete the task ASAP, I don’t like that. On the other hand, if unfortunately, things get wrong the GB will be delayed, I don’t like delays, the community don’t like delays.
    So…That’s the way how I work comfortably. When everything is done, I open an IC thread,…feeling great.
    Believe it or not, I prepare this IC thread for over two weeks.
    (More questions will be answered once you ask.)

The Spirit of DIY
As the boundaries between DIY keyboards and mass-produced keyboards get blur in late years, I consider Frusta not only a keyboard project, it’s also the reflection of the spirit of DIY. Let’s be honest, I gain all the knowledge and resources that are used to develop this project from the internet, from the mechanical keyboard. PCB design tutorials by ai03 and Hadi, VIA tutorials by Merlin, PCB libraries, Plate generator, Firmware support by the QMK team and VIA team, keycaps models for rendering and tones of other resources. It’s not being humble, I’m just telling the truth that this project won’t even exist without this community.

And that’s why I promise you I will open-source all the files of Frusta project, both case and PCBs. I hope the community goes better, and I do encourage you to learn how to develop your own mechanical keyboard, as long as you do not copy my work or use it for commercial purpose.
(I’ll upload the files to GitHub when I’m free, most likely after the GB)
