FEATURES

- Eclipse lip lowers front height even more and adds comfort for thumbs.
- Seamless side with minimal thickness bezels. Deep edge chamfer enhances the appearance without being too thin and affecting sound.
- Multi-directional alignment sections for easy assembly.
- Magnetic, swappable emblems are enamel filled and hand-finished.
- Built in TAP authentication microchip. Ownership can be registered and transferred.

PERFORMANCE

- Integrated 8 point silicone force-break to prevent unwanted resonance.
- Maximized internal mass while maintaining plate flex and low front height. Provides sound diffusion helping isolate second reflections.
- Optimized plate mounts for uniformal flex at home row. No mounts under the spacebar for best typing feel.
- Distance between the bottom of switches to case is equal across the board.
- Sound travels uninterrupted between PCB and bottom aluminum case. No weights, daughter board, foam, or screws are exposed to the bottom of PCB. Producing a uniform and bright sound-signature. JST cable is routed from the back of the chassis.

ASSEMBLY

- Convenient mountable magnetic weight. Can be removed while fully assembled with the included KEY tool.
- Cable Shield allows the use of a longer JST cable to make install easier and prevents wire damage. Cut from polycarbonate so you can see if the cable is pinched.
- Most popular 60% stabilizers can be removed without removing all switches. (Left shift, spacebar, enter)
- Pressure fitted feet that do not need to be removed for disassembly.
- Tadpoles and gummy o-ring can be customized to different harnesses.
- T10 Magnetic hardware for the entire build, can be built with the single included Torx bit.


V Status

Several rounds of 3D prints have concluded. Metal proto has been cut and currently in anodizing. For most update-to-date info please see Discord.

Release type, quantity, and colorways are still in development. Be sure to join discord to cast your vote on the remaining details.

Target price is $399.

I see. I like.

Would you like my card info now?

[Rafa_n]

Not a fan of the front lip thing, but everything else looks really cool.

Can we get some actual images of the board thought, without the book thing?

[POMChamp]

Looking forward to proto shots.

[_rubik]

The lookbook is clean. Are you planning to circulate a printed copy with the board?

Looking forward to seeing the protos

This presentation is a red flag. GL to the buyers.

[Keeaboo]

This presentation is a red flag. GL to the buyers.

IV Works has run many successful group buys with almost guaranteed weekly updates on the state of manufacturing and shipping. What's the red flag?

[StefanVoda]

The presentation + talking about sound design without an actual proto in hand. 3/5 points in the "performance" presentation are about sound, resonance, etc.

[_rubik]

The presentation + talking about sound design without an actual proto in hand. 3/5 points in the "performance" presentation are about sound, resonance, etc.

And that's why 3 of the first 4 comments are "this is interesting, now let's see the real thing". Also they've prototyped and are happy with the results. No reason to bash this soon

[xhxzzh]

Love the design, pls consider adding HHKB layout.

[Alvi]

After owning an AV4 and enjoying it immensely, this is an interesting project that I have been following via the discord. Would be interested in hearing what it sounds like!

This brand is a red flag for your wallet. GL to mine.

Definitely something I'll be looking forward to seeing some build vids of leading up to the GB

So, I guess 3D printed plastics have the same acoustic properties as alu.

[marshmellohs]

Looks interesting. Will echo that it would be nice to see the renders/photos outside of the photobook.

[Kokaloo]

i can't read what do the pictures say

[datAintFalc0]

OH WE'RE SO BACK. so sick as always, joe!

[spacegrey]

ok that's nice and all but can we actually see the "design student artbook" renders in non-book pictures please, i have hypermetropy and this does a good job in making my eyes hurt

[tactilesbad]

can we have actual renders in which we see the board in full please

[kollusions]

would love a solder and plateless option! looks sick

[Nuap]

Please consider HHKB top

[POMChamp]

Thanks for the renders! This is looking gooooood

[Keeaboo]

Waiting to see all the color options.

[IV]

Thank you for taking the time to comment, complete the IC, and/or join Discord. Has been a happy week finally getting to share this and talking with new people. I will do my best to implement the feedback you provided. I am also committed to the weekly updates as I do with all my projects.

The top request was more renders. Please see the updated first post for new looks of the Nox colorway. Also the proto PCB has arrived and I am very happy with the quality. Working now on finalizing the art and developing the firmware.

[NixieType]

This design is great. I think my only complaint is the lack of HHKB to help highlight the front lip (worked well on derivative). Aside from this, will we get WK renders soon?

[audax989]

watching this.

[vhaarr]

I think my only complaint is the lack of HHKB to help highlight the front lip (worked well on derivative).

HHKB doesn't only highlight the lip, it also allows the surface treatment to shine - especially along with a set of well-matching keycaps :-)

damn. it looks so good.

Update day!

I wanted to thank everyone again for their great feedback on the IC form. I have read over all the submission and starting to implement suggestions.

Last week I received the PCB prototype and have been putting it through its paces. I am pleased to share a first look at the PCB in the SPECS section of the first post!

[POCO Estudio]

pcb is so cool

[bombay.duck]

The 2x 3u bottom row is not easy to kit with existing sets unless one has purchased spacebar kits. And even then, a lot of spacebar kits don't provide 3u support.

The 2x 3u bottom row is not easy to kit with existing sets unless one has purchased spacebar kits. And even then, a lot of spacebar kits don't provide 3u support.

What do you recommend?

[Zouabee]

Love the lookbook! looks neat

[vhaarr]

What do you recommend?

I suggest you keep 3+1+3. Type K has 2x3u, and other recent boards like AKB Vero R2 (6/3+3) and goks Lily (3+1+3) have it as well. There are probably others.

3u is coming into vogue right now, and I like it. It looks so much better.

[stomaha]

Absolutely keep 3:1:3
