Hacker Camps & Maker Events in Europe

This is the culture-heavy corner of the European tech event calendar: hackerspaces, community congresses, outdoor hacker camps, and the maker-faire circuit. It traces a lineage back to the Chaos Computer Club and has grown into one of Europe's most distinctive community-event traditions. Equivalents exist elsewhere in the world, but few are as long-running or as well-attended as the European ones.

Anchor events include the CCC's annual Chaos Communication Congress and its outdoor counterpart Chaos Communication Camp, the regional CCC-family gatherings (GPN / Gulaschprogrammiernacht, FSCK, and friends), BornHack (Denmark), Electromagnetic Field / EMF Camp (UK), Fri3d Camp (Belgium), and past/future editions of May Contain Hackers (Netherlands) and Still Hacking Anyway. Around them runs the continent-wide circuit of hackerspace open days, maker faires, fab-lab workshops, repair cafés, and community digital-freedom events.

Content spans hardware hacking and reverse engineering, privacy and digital-rights activism, retrocomputing, art-and-code projects, lockpicking and physical security, amateur radio, embedded development, 3D printing, biohacking, and the unusually wide political and ethical conversation these communities sustain around technology. If "hacker" to you means curiosity and community rather than cybercrime, this is the scene. Brainberg keeps a hand-curated roster of the major camps and aggregates hackerspace events from across the continent, so the full European view shows up in one place.

Open Source night

Leiden, 🇳🇱 Netherlands

(english below) Vanavond gaan we aan de slag met den opensource projecten binnen de space! Wil jij werken aan onze deelnemer portal? Heb je een goed idee voor onze kiosk? Heb je een mening over hoe we dingen hosten? Kom je er vooral mee bemoeien we zien graag je merge requests tegemoet!

Naast de workshop is er ook ruimte om aan je eigen projecten te werken. Binnen Space Leiden is er onder meer een grote ruimte met werkplekken om alleen of samen met anderen verder te werken aan je project. Ook is er een houtbewerking lokaal met apparatuur voor als je meer praktisch aan de slag wilt gaan. Uiteraard staan de 3D printer en lasersnijder ook klaar voor gebruik.

Tonight we’re going to work on the open source projects within the Space! Do you want to work on our member portal? Do you have a great idea for our kiosk? Do you have an opinion on how we host things? Come and get involved — we look forward to seeing your merge requests!

In addition to the workshop, there’s also space to work on your own projects. Within Space Leiden you’ll find a large area with workstations where you can continue working on your project alone or together with others. There’s also a woodworking room equipped for those who want to get more hands‑on. Of course, the 3D printer and laser cutter are also ready for use.
