Projects

BrickMachine
Unsere Vision ist es, den Klemmbausteinmarkt nachhaltiger und effizienter zu gestalten. Weltweit existieren über 1 Billion LEGO-Steine, von denen viele ungenutzt bleiben, da manuelles Sortieren zeit- und kostenintensiv ist. Nach über drei Jahren Entwicklungszeit haben wir einen vollfunktionsfähigen Prototyp einer automatisierten LEGO-Sortiermaschine entwickelt und erfolgreich getestet. Wir bieten nun unseren Service sowohl im B2C-Bereich für private LEGO-Sammlungen als auch im B2B-Umfeld für Händler, Wiederverkäufer und Organisationen an. Das Projekt begann während unseres letzten Schuljahres, als wir LEGO-Steine von Hand sortierten und weiterverkauften, um unser Taschengeld aufzubessern. Dadurch mussten wir schnell feststellen wie nervig und zeitaufwändig die Sortierung von gebrauchten Steinen wirklich ist....
BuildMeUp
Empowering students to pursue a career in STEM (MINT). I want to inspire gymnasium-level students to discover robotics as a tool for solving real-world problems. By building and experimenting, they develop a mindset that blends human adaptiveness with machine capabilities. They should gain confidence in their skills and notice opportunities around them where technology can make a difference. Just as importantly, I want to demystify engineering by showing that progress comes from simplifying intelligently. As a student, I believed real engineering would be dull and “crazy complicated” because high-school simplifications wouldn’t apply. Now the goal is to show that choosing the right simplifications is powerful - and often the most exciting part of engineering: knowing what matters and what can be left out of the model. All models are wrong, but some are useful....
EduForma
The Mission:EduForma is an AI co-pilot that automates the entire planning workflow for Swiss teachers—from high-level yearly roadmaps to granular lesson plans. By solving the complex mapping of Lehrplan 21, we eliminate administrative burnout and return the focus to high-quality teaching.The Tech & StatusI have developed a functional MVP (FastAPI/React) integrated with LLMs, hosted on a secure Azure (CH) infrastructure. The core engine is built to handle localized curriculum data and is currently undergoing internal testing.The GoalMy immediate priority is to gather direct user feedback from Swiss educators to refine the UX and functionality. The ultimate vision is to transform the Swiss education system by making compliant, high-standard lesson preparation an effortless, 5-minute task....
Fix Your Stuff: Student Repair Cafè Zürich
To create a culture of sustainability and self-repair within the student community, reducing waste and promoting resourcefulness by empowering students to fix their belongings instead of discarding them.Until now we carried out more than **10 Repair Cafés**, where we provide tools, assistance and support, coffee and snacks. We **fixed a lot of stuff**, such as: clothing items, small electronics, furniture.Our main goal is to keep empowering students to repair their belongings and host many more Repair Cafés.The Student Repair Café started organically with Roman (ETH alumnus) and Maxime (PhD student), who loved tinkering, fixing things, and taking on technical challenges. They soon brought in Serena, who worked at the SPH Makerspace and shared their passion for hands-on repairs. Together, they turned their idea into a community-driven initiative where students can repair, learn, and connect....
Kapda
How would you dress in the day humanity overcame climate collapse? We’re Kapda. In collaboration with local shops, artists, and designers, we’re bringing Zürich a vision of that future through a sustainable fashion show next fall.Our goal is to use the runway to promote local sustainable retail and make circular fashion more visible and accessible. We already have a venue, website, social media presence, and posters, and are currently looking for event partners. Every look will be created from upcycled garments or second-hand pieces sourced locally. The show will also give students and emerging creatives a space to experiment with sustainable design and present their work.Kapda began with a simple question: what if fashion could help imagine a brighter future? Our team came together through a shared passion for sustainability and the desire to turn that vision into something real and engaging. Kapda is now a small, friendly group of students working to show that second-hand and upcycled clothing can shape the future of fashion....
Orbiit
Orbiit is a compatibility-based matchmaking platform for both friends and partners. Users create a profile and complete a survey focused on values, communication style, needs, and goals. Instead of offering endless options, we provide curated matches designed for genuine alignment. When both people agree, we coordinate the logistics to help them meet in real life. Orbiit was created in response to growing swipe fatigue and superficial digital interactions. We noticed that many platforms optimize for engagement rather than real compatibility. Orbiit was built to shift the focus back to quality, clarity, and meaningful in-person connection. We’ve launched our first in-person matchmaking events and attracted over 100+ early users through word-of-mouth and campus outreach. Our main goal is to develop a research-backed dating app that offers compatibility-based matching and real-world meetups, creating a more intentional and emotionally intelligent way to date. The project started after a breakup, when one of the co-founders began dating again and realised the dating world felt disconnected and surface-level. She shared her experience with her best friend and now co-founder, and together they decided to create a platform that could offer something better. Fly into Orbiit with us....
Rachel AI
Rachel is a voice AI agent developed at the ETH Student Project House that answers inbound support calls in German and Swiss German — resolving routine inquiries autonomously and handing complex cases to humans with full context. We have built a working voice AI prototype and validated the problem in over a dozen discovery conversations with Swiss companies, supported by structured B2B outreach and a fully Swiss-hosted architecture as core differentiator. Our main goal now is to scale on the client side: converting conversations into pilot projects and building our first reference customers. The project started with Peter, who was already building a voice AI prototype on his own. He and Philip reconnected via email — they knew each other from previous ETH projects — and Philip was immediately drawn to the topic, having heard about exactly these challenges from customers in his B2B sales work. With Philip's sales background and Peter's machine learning expertise, one piece was still missing: Adrian, who was already running his own IT consulting business with clients....
Recycling 3D Printer Plastics
After finding out that SPH doesn't recycle its waste plastic from the 3D printers, I wanted to do something about that. Recycling these plastics is possible, and with enough care taken to sort them, they can be reused for 3D printing with results comparable to original filament. The extrusion is carried out with an Artme MK3. Most of the input material is failed 3D prints, design iterations, and support material. That needs to be sorted for a high quality result, removing impurities and other types of plastics. One difficulty for reaching a good quality result is polymer separation: PLA and PETG need to be reliably separated. After shredding into granules, the material is extruded into 1.75+/-0.03mm filament. This is comparable to Prusa's commercial PRUSAMENT at 1.75+/-0.02mm.Custom colours are then also possible.Polycarbonate from recycling the sides of Prusament spools is also possible to extrude into filament, but more difficult. ...
