Our monthly Music Synthesizer Meetup and Jam Session!
First jam of the year!
Bring something you can make noise on, plug in, and play along!
If you have more than one device, please bring your own mixer.
No matter what, please bring whatever cables you need for your setup.
If you need a modular clock, please bring a long wire to get it from across the table. We will do our best to accommodate everyone, but our outputs are limited. If you have splitters or can daisy chain gear, please be prepared to do so.
If you can provide modular clock and a drum beat, and maybe a simple bass line, you may end up driving the jam!
It's always going to be an odd mix of styles and hardware that don't always work together, but are usually interesting, so embrace the chaos and come on out!
While the jamming ends by 10pm out of courtesy for the neighbors, people are welcome to stay after and chat about synth related stuff, debug their gear, show off their toys, get an X-Hain tour, make new friends, and restore your faith in humanity.
All because you decided to come play synthesizers with a bunch of strangers... isn't that grand!

Work / Life Balance in the Age of AI Agents ☼
26/03/2026 - 19:00- 26/03/2026 - 20:30
This meetup serves as a discussion group and exchange for those already heavily utilizing AI tools who are concerned about burnout. It is also open to anyone interested in exploring strategies for maintaining a healthy work/life balance as AI agents become more prevalent.
We live in an era of unprecedented access to AI-powered tools that allow us to build software, hardware, and other projects at a pace unthinkable just a few years ago. Tasks that once required an entire team and several weeks or even months of work can now be completed by a single individual in a matter of days.
While multitasking across multiple agents - using tools like Claude Code, Codex, and OpenClaw - is incredibly empowering, it can also become addictive. The “I (feel like I) can build everything!” epiphany is exhilarating, but for many (especially those with ADHD), it can rapidly lead to overextension and the erosion of personal time.
This raises a vital question: What will mental health and work/life balance look like in the age of AI agents, both now and in the years to come? Let’s discuss and learn strategies and best practices.
Organized by Kitty (Glowingkitty/Marco).

Berlin Permacomputing Meetup ☼
19/04/2026 - 16:00- 19/04/2026 - 20:00
Can someone with access to the calendar adjust the text for the permacomputing event on apr 19?
Description:
Permacomputing is a term that combines “perma” — as in permaculture — with “computing,” signaling an effort to rethink digital technology not as a disposable commodity but as a domain that can be part of sustainable, cyclical, and regenerative practices. Instead of equating technological progress with ever-increasing performance, bigger infrastructures, and rapid replacement cycles, permacomputing asks how digital systems can exist within ecological and planetary limits and still remain meaningful and functional.
The topic of the meetup is going to be: L5 – A Creative Coding Response to Permacomputing
with https://leetusman.com/
L5 is a creative coding library in the family of Processing languages, implemented in Lua with LÖVE. It attempts to reckon seriously with principles of permacomputing, including design and documentation for offline use, suitability for older hardware, design for longevity, and exposing the underlying infrastructure. After a brief presentation and discussion of the project, we'll discuss where it aligns and where it strays from permacomputing.

Music Synthesizer Jam Meetup ☼
23/04/2026 - 18:00- 23/04/2026 - 22:00
Our monthly Music Synthesizer Meetup and Jam Session!
Bring something you can make noise on, plug in, and play along!
If you have more than one device, please bring your own mixer.
No matter what, please bring whatever cables you need for your setup.
If you need a modular clock, please bring a long wire to get it from across the table. We will do our best to accommodate everyone, but our outputs are limited. If you have splitters or can daisy chain gear, please be prepared to do so.
If you can provide modular clock and a drum beat, and maybe a simple bass line, you may end up driving the jam!
It's always going to be an odd mix of styles and hardware that don't always work together, but are usually interesting, so embrace the chaos and come on out!
While the jamming ends by 10pm out of courtesy for the neighbors, people are welcome to stay after and chat about synth related stuff, debug their gear, show off their toys, get an X-Hain tour, make new friends, and restore your faith in humanity.
All because you decided to come play synthesizers with a bunch of strangers... isn't that grand!

Every other Thursday, MakeHERspace takes over and xHain becomes a FLINTA-only space for the entire day, from noon to 7am the next day.
The mission of MakeHERspace is to turn xHain into a comfortable, safe space for women, and other members of the FLINTA community, free from masculine energy and attitudes.
FLINTA means Female, Lesbian, Intersex, Non-Binary, Transgender, and Agender. Sometimes this is referred to as ABCD; "All But Cis Dudes".
Our management includes cis and trans women, and our membership includes and enthusiastically welcomes most flavors of FLINTA, including a large number of trans women. People who object to that are not welcome (No TERFs).
If necessary men can grab/drop off urgent works and quickly leave the space with a low profile.
A more detailed policy can be found at https://wiki.x-hain.de/en/MakeHERspace .

OpenMates Meetup (Privacy & safety focused AI chabots/agents) ☼
19/05/2026 - 19:00- 19/05/2026 - 21:00
A lot of exciting new changes have happened in the recent months regarding OpenMates.org. To make it not just a more privacy & safety focused open source alternative to ChatGPT, Claude, OpenClaw etc., but to build AI team mates that are also more useful and reliable for everyday tasks like finding doctor appointments, apartments, events, flights and train connection, as well as planning and building projects and so much more.
Effectively building the next generation operating system for a wide range of daily tasks & learning. All while ensuring that user interests are put first in every architecture and design decision, NOT advertisers.
Now, with the first 200 active users, many more visitors, and close to 8000 git commits, let’s come together to talk about the next steps of OpenMate and to move OpenMates from a single person project to a team effort.
If you are a user, developer, designer, storyteller / marketing enthusiast or community builder or just are curious about the project - feel free to join the meetup and contribute in building a real alternative to big tech :)

Music Synthesizer Jam Meetup ☼
18/06/2026 - 18:00- 18/06/2026 - 22:00
Our monthly Music Synthesizer Meetup and Jam Session!
Bring something you can make noise on, plug in, and play along!
If you have more than one device, please bring your own mixer.
No matter what, please bring whatever cables you need for your setup.
If you need a modular clock, please bring a long wire to get it from across the table. We will do our best to accommodate everyone, but our outputs are limited. If you have splitters or can daisy chain gear, please be prepared to do so.
If you can provide modular clock and a drum beat, and maybe a simple bass line, you may end up driving the jam!
It's always going to be an odd mix of styles and hardware that don't always work together, but are usually interesting, so embrace the chaos and come on out!
While the jamming ends by 10pm out of courtesy for the neighbors, people are welcome to stay after and chat about synth related stuff, debug their gear, show off their toys, get an X-Hain tour, make new friends, and restore your faith in humanity.
All because you decided to come play synthesizers with a bunch of strangers... isn't that grand!

A short description of the event would be: "Reticulum is post-internet, unstoppable mesh networking for all. Whether you are curious or already running your own nodes, join an informal meetup to discuss all things Reticulum!"

Remote controlled ball pit for 40C3 (Brainstorming & orga) ☼
13/09/2026 - 15:00- 13/09/2026 - 17:00
Leipzig congress had a ball pit on wheels - which was a lot of fun to ride around in! With 40c3 going back to a space with lots of flat same level area (at Hamburger Messe), it's a great chance to revive the ball pit idea and upgrade it.
The core idea:
- building a ball pit, for 2-3 people (smaller than the Leizpiger version, but should be more practical to build and transport)
- motorized (using hoverboard motors?)
- remote controllable via a web app (including fun multi player modes. Because who said a ride should be straight forward? The trip is the goal :D) - with optional game controller input
- distance sensors and auto break functionality to prevent crashing into people, walls and objects
And ideally:
- autonomous driving
- incl. ride haling
If the project sounds fun & interesting to you - let's come together and brainstorm the technical details and realization (software, electronics, structural materials etc.) as well as how to organize the transport to 40c3.

3D Printing Introduction ☼
30/09/2026 - 18:30- 30/09/2026 - 19:30
ntroduction to 3D printer lab and processes. Includes information about the software used to prepare your model (~30 min), as well as information about printers and processes (~30 min).
This introduction is mostly oriented towards members (or soon-to-be members) with all levels of experience who want to be authorized to use the printers in the space. You must do this introduction before you are authorized to use the printers. It is not a great opportunity for intensive 1:1 help with projects (because there are too many participants).
NOTE: You cannot print at Xhain unless you are a member (https://x-hain.de/en/participate/#content)
No need to sign up - you can just show up in the lobby right as you enter the space at the start of the session!

Music Synthesizer Jam Meetup ☼
22/10/2026 - 18:00- 22/10/2026 - 22:00
Our monthly Music Synthesizer Meetup and Jam Session!
Bring something you can make noise on, plug in, and play along!
If you have more than one device, please bring your own mixer.
No matter what, please bring whatever cables you need for your setup.
If you need a modular clock, please bring a long wire to get it from across the table. We will do our best to accommodate everyone, but our outputs are limited. If you have splitters or can daisy chain gear, please be prepared to do so.
If you can provide modular clock and a drum beat, and maybe a simple bass line, you may end up driving the jam!
It's always going to be an odd mix of styles and hardware that don't always work together, but are usually interesting, so embrace the chaos and come on out!
While the jamming ends by 10pm out of courtesy for the neighbors, people are welcome to stay after and chat about synth related stuff, debug their gear, show off their toys, get an X-Hain tour, make new friends, and restore your faith in humanity.
All because you decided to come play synthesizers with a bunch of strangers... isn't that grand!

Remote controlled ball pit for 40C3 (Brainstorming & orga) ☼
31/10/2026 - 16:00- 31/10/2026 - 18:00
Leipzig congress had a ball pit on wheels - which was a lot of fun to ride around in! With 40c3 going back to a space with lots of flat same level area (at Hamburger Messe), it's a great chance to revive the ball pit idea and upgrade it.
The core idea:
- building a ball pit, for 2-3 people (smaller than the Leizpiger version, but should be more practical to build and transport)
- motorized (using hoverboard motors?)
- remote controllable via a web app (including fun multi player modes. Because who said a ride should be straight forward? The trip is the goal :D) - with optional game controller input
- distance sensors and auto break functionality to prevent crashing into people, walls and objects
And ideally:
- autonomous driving
- incl. ride haling
If the project sounds fun & interesting to you - let's come together and brainstorm the technical details and realization (software, electronics, structural materials etc.) as well as how to organize the transport to 40c3.

Virtual Meetup Link
Discord: Email neoluddite@victorgom.es for an invite!
If you’re joining for the first time, I’d suggest you read this before anything else for brief context: What the Luddites Really Fought Against by Richard Conniff.The only expectation is that you read the chapter(s) of the book that’s listed for that meeting. You’re still welcome to participate if you haven’t done the readings as long as you are mindful. For each chapter, I’ve also noted some optional readings for context, so I’d suggest checking those out rather than reading ahead in the book. And remember, if you ever find yourself struggling with any of the readings or concepts, reach out! Either directly to me over email or to the entire group over discord.

Neo-Luddite Reading Group ✫
10/12/2026 - 18:30- 10/12/2026 - 20:30
We’re reading the final third of the book for this month! Check out the full schedule at victorgom.es/neoluddite
Virtual Meetup Link
Discord: Email neoluddite@victorgom.es for an invite!
If you’re joining for the first time, I’d suggest you read this before anything else for brief context: What the Luddites Really Fought Against by Richard Conniff.The only expectation is that you read the chapter(s) of the book that’s listed for that meeting. You’re still welcome to participate if you haven’t done the readings as long as you are mindful. For each chapter, I’ve also noted some optional readings for context, so I’d suggest checking those out rather than reading ahead in the book. And remember, if you ever find yourself struggling with any of the readings or concepts, reach out! Either directly to me over email or to the entire group over discord.
