Roan Jonker

Hello there! I am Roan Jonker, an engineering student who enjoys learning new skills above all else. This has turned me into somewhat of a polymath. Here, you can find some of my past work and what I am currently up to.

Taking Flight

In 2024, I obtained my pilot’s license while taking part in a drone-building competition—an experience that sparked a deeper interest in aviation and unmanned flight. Since then, I’ve continued exploring the field by flying a DJI drone to gain hands-on experience and experiment with aerial videography. This project page showcases the custom-built drone I worked on, along with a selection of my video footage captured from above.

Exploring the Power of Magnetism

Magnetism has long captivated my interest, beginning with a high school VWO exam project where I developed a method to charge a phone using a bicycle dynamo. That early experiment sparked a series of explorations into electromagnetic applications.


Currently, I’m working on two compact-scale engineering projects: a magnetic levitation platform with induction-powered LED lighting, and an electromagnetic accelerator. Both are designed as functional desk-sized models, combining physics, design, and innovation in a hands-on format.

The Bionic hand

For some time now, I’ve been developing the first prototype of a bionic hand. The idea originated from a search for a project that could combine several of my core interests: robotics, biology, and the desire to help people.

The project is currently a work in progress. To explore the full development journey so far, feel free to visit the project page.

Diving Into AI—From Curiosity to Capability

Since starting my minor course, I took a deep dive into the hype around AI. Implementing it in different ways while building a business was interesting—but there’s more to explore. So I decided to learn beyond the basics and work toward becoming efficient with the tools: from improving prompt-writing to setting up chats with specific parameters.
I also started working with generative AI, including computer vision, locally hosted workflows, and LoRa training.
This hands-on approach has helped me get up to speed quickly. I now see AI as a powerful tool that boosts my efficiency—especially when I need a third hand or a second opinion.
