↘THE JOURNEY OF AN IDEA
Connected worlds.
From hardware to interfaces to human experience. Scroll through three connected perspectives.
Then, working systems.
Analysis with MATLAB, communities on the web. The software layer that turns calculations and ideas into usable tools.
Try the 3D circuit ↗And a place in someone's day.
A clear weather forecast, a shared film discussion or a language learned together. The person using the product stays at the centre.

✳DISCOVERY STUDIO
Look closer. Interact. Understand.
Four little experiences, one shared curiosity. Models are illustrative; device screens come from real projects.

BEYOND THE PARTS
The parts that make a system.
Select a part or separate the assembly. This is an illustrative prototype explaining component relationships, not the research project's actual CAD model.
REAL SCREENS
The story inside the screen.
Switch projects and screens, and rotate the device. These are project screenshots rather than embedded live applications.
IDEAL SERIES RLSee the phasors and calculation ↓
Change values. See the response.
The same calculation as the phasor lab below. Moving dots illustrate flow; they are not a field or electron simulation.

A LITTLE CONNECTION GAME
Bring the robot to life.
Select two terminals in turn to complete three connections, then turn on the switch. You can also select terminals in the 3D scene.

Ideas, brought to life.
From platforms that connect communities to engineering tools. Projects I learn through building.
A community brought together by books, films and shared curiosity.
Bringing outdoor adventures, team spirit and competition into the digital world.
Weather across Türkiye, fluid charts and clear meteorological data.
Numerical analysis of medium transmission lines using T and Π models.
An exploration and atlas space for the Vizyon community’s shared pixel canvas.
Film tournaments, head-to-head duels and a community awards night.
A club combining Ottoman Turkish reading, learning and map exploration.
A system aiming to turn ESP32-CAM images into spoken descriptions through Firebase and an Android app.

Don't just look, give it a try.
A standalone demo inspired by my MATLAB work. Change two values and see how the circuit responds.

EYYÜPHAN ÇAKIRCURIOSITY → CREATION
An engineer's mind.
A builder's curiosity.
I'm Eyyüphan Çakır, an electrical and electronics engineering graduate of Karadeniz Technical University. In my graduate studies at Giresun University, I research smart glasses applications for visually impaired users and embedded systems.
As founder and lead developer of Vizyon Book and Film Club, I bring communities together online. Volunteer youth leadership, web platforms and Android apps are all part of my journey of building and sharing.
