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.
