Description

BOOMERANG

8-degree split 60XT

IC FORM

INTRODUCTION

I always loved the FLX virgo but I knew I would not use the nav cluster if I got one, so I decided to make my own version of the layout. That is it. No introduction or drawn-out inspiration. I wanted something so I made it. If you also like what you see, then well fill in the IC. If you don't, thanks for reading this.

DETAILS AND TECHNICAL INFORMATION

Materials: Copper weight, aluminum top/bottom
Dedicated ANSI/ISO plates. Ansi shown below.
Hot-swap and solder PCBs
Typing angle: 6.5 degrees
Split angle: 8 degrees
Front height: ~18.1 adjusted at lowest point.
Weight: ~2.4 kg built
2 mm diameter o-ring
M3x10 front screws, M3x20 back screws
Fly DB, MOLEX-MOLEX. No daughterboard cutout on bottom of case
Through-weight design
WRIST REST WILL BE OFFERED
Mounting: o-ring wraps around the plate tabs, like F1 but self-aligning.

Assembly to be shown in detail when prototype arrives. In a nutshell the oring wraps around the plate tabs, like F1 but self-aligning.

ASSEMBLY

I have made 4 prototypes:

Fully F1 oring mount: Did not like it, assembly was horrible and it just did not work well.
Partial oring with screw underneath: It worked and was good but it was hard to show how much to tighten screw, so option 4 was made
Top mount: I went a bit crazy and made a top-mount version: It is amazing but in the end I made option 4
Fully F1 oring mount, fully wrapping: I made another board with this exact same mount and the experience was perfect, so I took the exact dimensions and translated them here. That is it.

ALIGNMENT

In the photo below, the blue highlighted area are the alignment and force-break orings. To be clear the force break aspect is an added bonus, not to fix any ping, there is no ping whatsoever. The only reason for the orings is to align the top-bottom cases without using pins or metal alignment tabs. I want as little metal-metal contact.

MOUNTING

The way the board is mounted is super simple. You take the oring, slot it into the cutouts on the tabs and you place it on top of the board. Because of how the board is designed this is self-aligning, meaning the plate will always be in the correct position. I will explain this when the prototype arrives, but you can see how in the up-down direction the oring is constrained by the plate and then once again by the channel underneath, so it cannot move up-down out of alignment. Side-side same thing, the oring has nowhere to go and will always stay in the channel.

Additionally, those with a keen eye can see that the leaf spring is shifted to the outside of the tab. This is because the inside of the tab is supported by the adjacent tab, but the extremes of the tabs (left and right bezels basically) those are supported only by 1 tab, so you have to make them stiffer for the board to feel homogeneous throughout.

WRIST REST INFORMATION

For those who did not pay attention and said that the wrist rest made out of aluminum is pointless, please refer to the silver render. While the wrist rest is indeed made out of aluminum, I added rubber stoppers to avoid metal on metal contact. I have added the render where this is shown below for reference:

I have tested this and due to the geometry of the bottom, with 2 feet, one on either side there is zero metal contact. However, due to popular demand I have also quoted PC for those who rather get that instead.
