Listing Hackathons

As the name suggests, TOMfoolery brings a lighthearted and welcoming atmosphere; perfect for freshmen and students who may not yet be deeply familiar with modern technology. But don’t be fooled by the playful name :) The challenges participants will tackle are rooted in real-world issues, focusing on topics that impact both our local campus ecosystem and the broader regional environment.

Europe is at a turning point: The need for faster, bolder defense innovation has never been greater. That’s why we’re bringing together 100+ hackers, builders, and visionaries from across Europe and beyond for a three-day hackathon in Switzerland. This isn’t just another hackathon—it’s the launchpad for the next generation of dual-use and defense technology! Visitors To give teams space to focus, there will be no visitors during the hackathon itself. If you want to see the results, join us for Demo Day on Sunday, October 26, where teams will showcase their prototypes and solutions.

Hacken bis der Arzt kommt!

Hacking Smart Cities: How to Defend European Critical Infrastructure Roundtable, Simulation, Strategic Dialogue This exclusive event brings together executives, top experts, political decision-makers, industry representatives, and media stakeholders at the intersection of technology, security, infrastructure, and geopolitics. The program provides a high-level forum to assess the accelerating evolution of cyber-physical threats and to discuss strategic approaches to strengthening Europe’s resilience and critical infrastructure. Strategic Focus Europe is undergoing a profound structural transformation. Machines, vehicles, buildings, transportation networks, and supply systems are converging into cyber-physical ecosystems that are interconnected, automated, and increasingly governed by real-time AI. This integrated operational landscape enables unprecedented efficiency and innovation, but also introduces systemic risks that extend far beyond traditional IT and cloud environments. At the center of this shift are connected buildings and smart cities: multilayered environments where energy, data, automation, mobility, and human interaction intersect. Their growing reliance on AI-driven control systems and digital operational layers makes them both strategic assets and strategic vulnerabilities in modern threat scenarios.

Time to Solve Real Problems 🚀 Join us and 90+ hackers from all across Europe for the BuildArena Hackathon on Feb 11-12 in Stockholm, Sweden! This hackathon is co-organized by Techarena, Lovable, Project Europe, European Defence Tech Hub and Inflection Fund. Goal This is a special 12h (+11h without sleep) hackathon with 3 different tracks. Teams will be working in parallell in different tracks, representing different problems to solve.

An open-ended session to explore and play with the Gemini Live API together. No fixed agenda, no predefined outcomes. We’ll have time and space to tinker, try things, and see what emerges when working with real-time AI systems. Some people may hack, some may observe, some may jump in midway. That’s all fine. Notes There’s a small React starter for Gemini Live available if useful: https://github.com/loffloff/gemini-live-react A small side project in a similar spirit exists here: https://www.deflectionrate.com/

REVEL and NVIDIA are hosting the world's largest Physical AI hackathon with over $100K in prizes, including GPUs, dev kits, and a full humanoid robot. The multi-month event, running from December 15, 2025, to the end of February 2026, is structured to attract talent from all corners of the robotics world. With Pro, Amateur, and Junior tracks, everyone from seasoned industry teams to high school clubs can compete. The entire competition is built on NVIDIA’s formidable robotics stack, with challenges designed to be tackled first in NVIDIA Isaac Sim, a simulation platform built on Omniverse, before real-world validation. The challenges will cover everything from manipulation and perception to “agentic control,” and will even feature modular tasks from The LEGO Group and LEGO Education, presumably to ensure the next generation of roboticists knows their way around a brick separator. Beyond the headline-grabbing humanoid, the prize list is a robotics engineer’s dream. Top winners can expect to snag RTX 6000 Blackwell GPUs, Jetson Thor developer kits, and various robotic manipulators. The winning teams will also be flown to San Jose, California, for a prize ceremony just before NVIDIA’s GTC conference in March 2026.
