If you don’t already have your tickets to Hackaday Europe, pick them up now. The clock is ticking! Today, we’d like to announce our keynote speaker, the remainder of our featured talks, and two more workshops. (And if you want workshop tickets, which always go fast, get those soon!)Hackaday Europe is super excited to welcome back Hackaday Superfriend [Sprite_tm] to kick off the event with a keynote talk on how he made a retrogaming PC from bare silicon. Don’t miss it.Jeroen DomburgBuilding a retro-PC…From ComponentsWhat if you could build a retro-gaming PC from bare chips? No emulation. No ancient hardware. Jeroen walks through designing a compact 486 SBC with modern amenities, starting from the silicon up. Edwin HwuPlayStation 4 to Psychometer: Skin Nanotexture BiometricsTurn a PlayStation 4 optical pickup into a high-speed dermal atomic force microscope. Edwin shows how hardware hacking and deep learning combine to assess skin conditions and potentially detect stress non-invasively.Erin KennedyOutdoors with Robots: Adventures and Lessons LearnedTen years of taking robots into the real outdoors, through sand, mud, and wildfire zones. Erin shares what happens when nature-inspired machines meet nature itself, and what she’s learned building them.Stephen CoyleMaking physically intuitive electronic instrumentsOur physical intuitions about inertia, momentum, and gravity shape how we play instruments. Stephen explores what happens when digital instruments simulate these properties and what new musical possibilities emerge.Sylvain HuetBare metal made easyAs tech grows more opaque, there’s an urgent need to return to simple, hackable systems. Sylvain presents an ambient computing vision; devices that blend into life rather than dominate it.Alex RenHack Club: How to get 2000 teenagers hacking their own hardware projectsA 3D printer made of Lego. DOOM running in a PDF. These are Hack Club projects built by teenagers. Alex shares the tools, culture, and community behind hardware hacking at scale for young makers.Michael WiebuschBuild a Cable Modem for your Arduino. For 2 Euros. But it’s not a Modem.Electric signals travel in two directions in a coaxial cable, and they don’t mix on the way. Michael explains transmission line theory and demonstrates why it matters for RF and high-speed digital design.Anders NielsenHigh Performance SDR on the cheapRF, high-speed USB, analog chaos. Building a 20MHz continuous bandwidth, 3GHz-capable SDR without breaking a $50 BOM, achievable with a single FPGA on a carrier board.Federico TerraneoFluid kernels and how to optimize C++ for microcontrollersA 20-minute tour of the fluid kernel architecture, the Miosix RTOS as a practical implementation, and 18 years of hard-won tips for writing efficient C++ on microcontrollers.Benjaminas SulcasFault injection 101A hands-on workshop covering the basics of hardware fault injection, power glitching, EMFI, and practical comparisons of tools available to hardware security researchers and curious makers.Davide GombaLet’s Mesh!A practical dive into mesh networking with Meshtastic and Reticulum; installing, configuring, and communicating across decentralized mesh programs. Leave with hands-on experience and a new view of off-grid connectivity.If you’re joining us and you’re not on the list above, you can still take the stage! We’ll have time for seven-minute Lightning Talks, hopefully enough for everyone. So bring your hack and bring a story. We want to hear it.[If you read this far, you probably want tickets. Just sayin’.]
