Overview
LP-63 is a compact 60% Hall-effect keyboard from Ziprime.
The core idea: keep full 4mm travel while lowering the front height and rethinking the bottom-out feel. Many Hall-effect boards already focus heavily on input features. LP-63 starts from a different question — can the physical experience of a Hall-effect keyboard feel more complete?
This is still a pre-production project. We're currently in the IC phase, collecting feedback while refining the design.

What Makes LP-63 Different
LP-63 is designed around a few specific structural priorities, not a feature checklist.
Lower front height without going low-profile
The ~13.8mm front height target is achieved by simplifying the internal stack and mounting switches directly to the PCB — not by using low-profile switches. Full 4mm travel is retained. The result is a lower desk presence and a cleaner wrist angle, without giving up the keystroke depth most mechanical keyboard users are used to.

Plastic stem bottom-out
The custom Hall-effect switch in LP-63 is designed around plastic stem bottom-out. The end of the keystroke is shaped by plastic-on-housing contact, not the harder magnetic stop found in many Hall-effect switches. The result is a less harsh, more familiar finish — closer to what traditional mechanical keyboards feel like at bottom-out.

Plateless O-ring mount
The rigid plate layer found in many keyboards is removed entirely. Switches mount directly to the PCB, and the assembly is suspended on O-rings within the aluminum chassis. Impact energy from bottom-out is not transmitted through a rigid plate into the case, so the keystroke resolves in a softer, more controlled way.

Tuned internal damping
Inside the aluminum chassis: targeted CLD strips, acoustic Poron layer, tuned internal clearance, and flexible support behavior. The goal is not maximum damping — it's managed resonance. Less sharp, less hollow, less metallic, but not dead silent.

Prototype Validation
We built an early engineering prototype to validate the core structural direction before committing to production tooling.
What was validated:

Front height direction (~12.6mm achievable with full travel)
Full 4mm travel retention confirmed
Plateless O-ring mount behavior tested
Basic acoustic character confirmed

What is not yet validated:

Final outer industrial design
Final acoustic tuning with production materials
Display integration
Final weight and dimensions

The prototype is an engineering validation unit, not the final product. Current product visuals are high-fidelity renders. Real photography will be added when production samples are ready.

FAQ
Is LP-63 wired or wireless?
Wired USB-C for the launch version. Wireless may be explored later, but only if it can be done without compromising the core experience.
Is this a low-profile keyboard?
No. LP-63 keeps a full 4mm keystroke. The lower front height comes from internal stack simplification, not low-profile switches.
Does LP-63 support Rapid Trigger or SOCD?
Yes. RT and SOCD-style input features are supported as part of the Hall-effect platform. These are included but are not the primary design focus of LP-63.
Are the specifications final?
No. Current figures are pre-production design targets and may change during engineering validation and production tuning.
Are these images renders or real photos?
Current visuals are high-fidelity design renders. Earlier engineering prototypes were built to validate the structural direction. Final design photography will be added when physical production samples are ready.

Feedback

This is still an early IC, and feedback will directly shape what comes next.

If you have a few minutes, we’d really appreciate responses through the IC form.


A few things we’re especially trying to understand:
   •   Does the full-travel + lower-front-height direction make sense to you?
   •   How important is plastic stem bottom-out / bottom-out feel in this category?
   •   What price range would feel reasonable for this project?
   •   Would you want more features, or do you care more about overall feel / structure?
   •   Are there any aspects of the appearance, layout, or color direction you would want changed?
   •   What would you need to see before feeling confident about the project?

Thanks for reading — all feedback is genuinely useful at this stage.[/color]
