Title: [IC] Ellipsis - 40% ortho split case inpired by The Ave

Interest Check Form 1: https://forms.gle/Em7S5jEDpfpcRJpt9 (https://forms.gle/Em7S5jEDpfpcRJpt9)
Form 1 closed. Form 2 will open as soon as I manage to work all the feedback into the next prototype.

The Ellipsis is my homage to The_Royal's The Ave (https://geekhack.org/index.php?topic=101236.0) adapted to a Let's Split / Levinson form factor.

Most recent renders
Individualism: Screws, weight and removable plate

Case versions
There will be two versions (individualism and minimalism) for the top case and for the bottom case each:
Each top case will be compatible with each bottom case.

Exchangeable switch plate, screwable bottom with brass weight

(Final versions still missing - will fix eventually!)

Link me on Instagram or Reddit if you make one yourself, I wanna see! (@rutomoda or /u/rutomoda)z

Due to several requests I designed an insert housing for a 32x128px OLED display. First prototype (will be improved):

I know I really want it, but I don't know if I want to pay for it to be aluminium.
The 3d printed proto is really cute, pls offer that?  ;D

Added the repo link to the main post, so anyone who wants to make one for themselves can do so.

Love the design. I'm going to think about the IC questions before answering. I feel like I could go for both a low-end and high-end version of this.

Did a prototype for an insert housing for a 32x128px OLED (see main post). I am listening to suggestions if possible! That said, IC form 1 will be closed end of tomorrow (Saturday), so make your voices heard! (This thread will of course remain open until the GB.)

This is the coolest dang thing I have seen in a loooong while. Really excited to see where this goes, this project is amazing!

Little Work-In-Progress update. Working hard on a polycarbonate version with separate plate, weight and screwable bottom.

First of all: Thank you guys for the compliments! Much appreciated!

There will be a custom PCB as this was heavily requested in the IC.

Please give us the option to buy just one (half? Idk). I would like one as a macro pad. Specially with the screen and the rotary encoder.

Thirded. Would absolutely be down for this. Also two 2u spacebars?

I also hope to use this as a macropad.

Just much more useful that most macro pads, SOAP looks cool, but this with display and rotary would be ace.

I finally got the design for the exchangeable switch plate done and finished! See main post!

Single side / macro pad option will be a thing!

Current to-do's (no particular order):

I currently have a lot of private things to take care of, so progress will be kind of slow. I would love to start the GB around the end of this year, but can make no promises. I will do my best!

Thank you again for all the positive feedback! This really helps me stay motivated!

In your most recent renders, what are the 3 holes at the bottom of the case? I can't seem to figure it out.

Probably cutouts to show the brass weight.

This exactly. I will add a render to make it clearer.

Ohhhh dang! I just realized it creates an ellipsis. That's super cool!

Yeah, trying to stay on theme as much as possible. Currently only the plate mounting screws are off, but those look weird with the spacer.


Renders added for minimalism version as well as an assembled bottom view.

Just a little update to keep you guys in the loop.

There is quite a lot of private stuff going on with me right now, so development is super slow. But I think I have the PCB schematic now where I want it to be. I had a **** ton to learn about ESD and EMI management I had not payed attention to so far, but I want to deliver the best product possible so I read through a wealth of forum posts and company white papers.

PSA: if my research is correct, most split keyboards are NOT ESD SAFE!

An ESD is a high voltage and therefore high energy pulse shocking a system due to electro static discharge. It is the same as touching a door handle and getting shocked. The Let's Split, Levinson Rev2 and Corne PCB all do not have ESD protection on the TRRS jack. Touching the contacts of the TRRS plug can easily raise the voltage level to several thousand volts and fry the circuits on the PCB.
Disclaimer: I think this should only be possible if the PCB has an active ground connection, meaning the USB is plugged in or there is another connection to ground, and if a TRRS contact other than the ground (usually sleeve) receives the ESD. Also I am a novice regarding this topic and have not done any actual ESD testing so far. I will however install the recommended measures to the Ellipsis PCB, since that boils down to just adding appropiate TVS ICs between signal path and ground.

Besides that figuring out how to connect the main cluster PCB to the PCB for the angled part took some tinkering and digging around. Since the angled PCB is not symmetrical but mirrored between sides I wanted to have it be flippable. I think I have a solution which should work, but I will have to see during actual layout if I have the space.

Speaking of space, there needs to be another revision for the top parts of the case to add more space for the angled PCB, which is currently to small for Kailh hotswap sockets.

And last but not least the angled part should support an encoder in any of the three positions and there might even be up to 8 different encoders available in the main cluster. This depends on a new QMK feature and I am not 100% certain that this will work as I currently understand. Fingers crossed that everything works out.

@Ruto

If you use serial and not I2C for the halves, it only takes 3 wires, you can then dedicate the 4th conductor in the TRRS for ESD to connect to the chassis/shield of both halves.
