Easter Monday carries a different kind of energy — somewhere between a long weekend, a fresh start, and the feeling that spring is finally here. This Social Butterfly Club Meetup brings that energy into a relaxed Monday evening. A space to connect, share conversations, and start the week with a bit more lightness and curiosity. 🌷 There might be a few small Easter surprises hidden around — nothing too serious, just a playful excuse to look around, smile, and maybe start a conversation with someone new. 🐣 Whether you’ve spent the weekend with people, by yourself, or somewhere in between — this is a chance to step back into the city and connect. ✨ Suggested Ice Breaker Question: “What has been a highlight of your long weekend?” Orga This meetup is donation based.

Hallo Zusammen, bei trockenem und schönem Wetter können wir die Runde um den Müggelsee machen. Der Winter ist vorbei, Zeit, sich wieder auf die Kufen zu wagen. Beginn in S-Bahn Friedrichshagen, ca. 15:20, ich fahre ca. um 15:00 in Ostkreuz los. (Eis-)Bademöglichkeiten gibt es nach ca. 15 km am Strandbad oder nach ca. 9 km am kleinen Müggelsee. Getränke solltet Ihr in diesem Fall dabei haben. Ausstiegsmöglichkeiten gibt es nach ca. 15 km in Rahnsdorf oder bei Erkner - dann verpasst Ihr aber das beste Stück. Wenn wir über Köpenick zurückfahren, dann sparen wir und den Spreetunnel. Grundlegende Skate- und Bassibremskenntnisse werden erwartet. Jeder ist für seine eigene Sicherheit verantwortlich. Wer es nicht schafft - die Müggelseerunde ist eine der besten Berlins, ich plane sie noch öfters dieses Jahr.

Come play Magic's most accessible competitive format! We meet every Tuesday at 18:30 at RuDi-Das Stralauer Kultur- und Nachbarschaftszentrum in Friedrichshain, \~10 minutes by foot from Warschauer Str. and Ostkreuz. **The best way to get in touch is to join the WhatsApp group:** https://unlock.ly/I7IhAbb *Even if Meetup has only 1 or 2 RSVPs, we are normally 20-30 people every week!* **FAQ:** **Do I need my own deck?** No, people that come bring extra decks, and you are free to borrow one if you want to test the format before buying into it! **Casual or Competitive?** We play casually to allow people to come late and leave early. Feel free to stay for any amount of time between 18:30 and 22:30. To this end, feel free to bring proxies, as long as it is clear what card you are proxying! **Why do you charge an entry fee?** Our 2 euro entry fee is a donation to the community center that we use to host our event.

Bring your Raspberry Pi, Arduino, microcontroller, or any other electronic project and join fellow electronics makers for a night of creativity and collaboration! This session is open forum to share your current projects—whether complete or in progress, it’s all interesting! Whether you’re deep into embedded systems, exploring new ideas, or just getting started, you’ll find a welcoming space to collaborate, share, and get inspired. **New to electronics or curious about tinkering?** You’re absolutely welcome. If you’re a beginner and want to experiment, I’ll have a couple of starter kits available so you can try things out—whether that’s blinking your first LED, putting something on a display, or experimenting with simple sensors. No pressure and no experience required—just an interest in learning and building. While we continue to pursue a more permanent venue for this Meetup, we’ll be using public library facilities based on availability. This session will be at the Worthington Park Library in the Olentangy Meeting Room.
