CONVEX – Tenting Full Layout Keyboard Kit w/ LCD Calculator

Hi everyone,

After 12 years of thinking and testing, my idea finally takes shape.
As an engineer, I often need to make quick calculations during work.
Every time, I had to reach for a calculator or open an app on my computer or phone — it was a small but constant inconvenience.

So I thought:
> “What if the calculator was right on my keyboard?”

That idea stayed with me for over a decade.
At that time, I couldn’t design PCBs or solder properly — so it was just a dream.
Now, with experience and help from the community, that dream is becoming real.

🧠 Comfort First – The E.M. Series
───────────────────────────────

As time passed, I started designing my own ergonomic keyboards —
from **E.M.1 to E.M.7**, and later **E.M.8 (tenting structure)**.
Using **Mont Cervin**, which was built on that design, I finally felt what true comfort could be.

That’s when I became convinced — *tenting works.*

💡 The Challenge: Full Layout + Tenting
───────────────────────────────

One day, a friend said:
> “I can’t give up full layout… but my wrists hurt so much.”

That question triggered this project.
Could a **full layout keyboard** also be **ergonomic and tented**?

At first, I thought it was impossible — too large, too complex.
But after a simple test using my **TOMAK61** with a tenting angle, I was surprised:
**Even light tenting made a huge difference.**

That’s when **CONVEX** was born.

⚙️ Calculator Function + Large LCD Display
───────────────────────────────

This project finally brings the feature I wanted 12 years ago —
a **built-in calculator**.

The PCB is being co-developed with *Baram* from Keyfam (키팸).
It will feature a **large, high-visibility LCD** integrated into the keyboard.
The firmware is designed for future expandability beyond simple calculator functions.
