Sunday Electronics Workshop
This workshop series is a **follow-up to the ESP32 Robotics workshop**, but with a different concept. Here, there will be no subject set in advance, instead **all participants are welcome to join at any point and at any level, from beginner to expert**. Beginners will be guided though the basics (C programming, how to use measurement tools, soldering, PCB design, etc…) and can get advice on what tools and kits to start with, others can come with their own projects to get help or share some knowledge.
## Requirements
* Bring your own laptop (Windows, Linux or Mac)
* Any microcontroller/dev kit to develop your project(s). If you are a beginner and don’t know what to buy, come and we’ll find the best starter kit for you !
* A strong desire to learn stuff, good mood and some patience !
Liberate Your Voice: A Shamanic Workshop
\* Do you feel blocked in your vocal expression?
\* Are you too shy or self-conscious when singing?
\* Would you like to have a strong, uninhibited, naturally-flowing voice?
\* Are you interested in learning how the voice can be a healing tool?
✨Join our workshop to awaken your true voice, the one that comes from deep within your body, and not from your limiting mind. We'll use shamanic tools to guide you to release the voice hiding inside you.
🕧 Sunday, 31st May 2026, 1-5 pm.
📍Merci Brussels, Place Julien Dillens 1, St. Gilles.
🎟️ Participation: 80 euros

UNO #476
Let's continue the tradition and play UNO, everybody is welcome :)
If you're on the waitlist please check your messages, especially on Sunday. If people drop off last minute I tend to message people on the waitlist to see who can come.
We'll be playing at the lobby of Radisson RED, Brussels. The address of the hotel is:
Rue d'Idalie 35, 1050 Bruxelles
My number is 0471 45 55 02. Feel free to call if you cannot solve a physics question, cannot find the place or simply need a hug.
I have quickly written a set of rules on how we play. It is assumed that the reader has a basic concept of the game.
***
Setup:
* Each player starts with 6 or 7 cards each (depending on total number of players)
* A card is shown in play in the middle of everyone, this is known as the top card.
Goal:
* The goal of the game for each player is to get rid of all cards in your hand
Rules:
* Whenever you go from two cards to one card, you have to say "UNO".
* Each player takes his turn one by one, initially going in the clock-wise direction
* A card may be played if it matches the same colour or same number or same type as the top card in play
* The two black cards (Draw 4 and Wild) can be played regardless of the top card in play.
* Interruption rule: You may interrupt the general flow of the game (clockwise or counter-clockwise) if you have the EXACT same card as the top card in play. If you manage to play the card prior to the person whose turn it's supposed to be, then the game continues on from you in the same direction it was previously. (Unless the reverse card was interrupted, then the direction changes).
* Draw2 or Draw4 cards can be played in accordance to the interruption rule. The following person after the interrupt has to take the accumulated number of cards. If however, cards have already been drawn AND seen by the person who was supposed to take the cards, then only the remainder of cards has to be drawn.
* Once someone has no cards remaining in his hand, play stops and we start counting points.
Points:
* Number cards have the face value as the number of points. i.e. number 6 is worth 6 points, number 0 is worth 0 points, number 4 is worth 4 points.
* Skip, reverse and Draw2 are worth 20 points each
* Wild and draw4 are worth 50 points each

Deep Conversation - Question Chosen in Session
Welcome to our weekly event in the upstairs room of The Sister Café, rue Chair et Pain 3, one block from the Grand Place. Please get there early enough to order your drink at the bar first. Thank you!
After introductions we will collect questions from the group participants, choose one by voting then discuss it for an hour. Then most of us stay for drinks and bizarre conversations.
Past questions have been wide and not confined to academic philosophy:
What is a genuine friend?
Is social media turning us into emotional zombies?
Do we lose some of the experience of things by defining them?
Are we driven by sex?
Is loneliness a personal failure?
Is morality relative?
**Crucially, be kind and respectful and generous** in your disagreements; remember how much you personally enjoy someone else proving you wrong before celebrating your cutting counterexamples.
Badminton Sunday Advanced
First time comers
Please make sure to read the rules and contact the organizer before! Otherwise you will be moved to waiting list. Apologies for inconvenience but we have to do it to avoid no-shows.
New and Interested in being part of our group? Join here, https://chat.whatsapp.com/KqdVhyuBhFz1d56lv4WVVi
Please Direct Message the Organizer with your level. Approval is required before your first RSVP.
Games format.
95% are double games (unless someone needs a break), typically 4 people play together 2 sets and then mix with players from other fields. We play with plastic shuttles - Yonex Mavis 2000 (which are provided).
Registration
If it's your first time, please send a private message to the host to confirm. No-shows are taken quite seriously because they unbalance the games a lot. Also once you register please keep an eye on you private messages, in case we need to contact you.
Players level
Having players with much less experience often unbalances the game making it much less interesting for more experienced players. We still try to be welcoming.
As a rule of thumb, if you know what a "clear" is, you are welcome to join.
Otherwise, feel free to get in touch with me (John) and we can see if we can arrange so you and existing players can have good experience playing.
Price and payments
The price of participation is EUR 9. Payment is on-site in cash, or via online. Info provided during or shortly after the event in the WhatsApp group.
Cancelations and no-shows
Switches and cancellations are free of charge if done more than 50 hours before the start of the matches
If you cancel within the 50-hour window before the event starts, you will be placed on the wait-list for the next week's event, whether or not a replacement is found. If no replacement is secured, you'll still need to cover your share of the costs.
Contact
Questions or first-time approval requests? DM the Organizer with your playing level and availability.
Badminton Sunday Social
Join us for some friendly Badminton games- all levels welcome!
IMPORTANT- in order to secure your place you’ll need to both book a spot on Meetup AND pay €8 by Friday morning. This is to make sure we can cancel courts if demand isn’t there, and make sure we’re being fair to people on the waitlist.

20k of Brussels? Nah, 15k of Peace & Quiet
🏃♂️ Missed the 20k Registration? Get Your Adrenaline Fix Here! 🌲
Sold out? No bib? No problem. While 40,000 runners are pounding the hot asphalt on the road, we are taking the FOMO to the forest. Welcome to the Alternative 20k (But Make It 15k & Beautiful).
Skip the massive crowds and the concrete, and join us for a stunning, shaded, and high-energy cruise through the best trails Brussels has to offer. You’ll still get that race-day buzz without the entry fee!
📅 The Game Plan
Date: Sunday, May 31, 2026 (Official 20k Day)
Meet-up Time: 09:45 AM (Sharp! We move shortly after)
Meeting Point: In front of the Main Tribune / Stands at the Hippodrome de Boitsfort (Drohme)
Distance: 15 km
Pace: Cruisy, steady 6:00 min/km
Terrain: Light, wide trails in the gorgeous Forêt de Soignes (smooth dirt paths, manageable elevation, completely under the tree canopy)
📍 Route & Vibe
Starting from the historic Hippodrome, we will dive straight into the green lung of Brussels. We will trace a beautiful 15k loop through the Forêt de Soignes, keeping the pace locked at a social but solid 6:00/km. Expect fresh air, zero traffic, great conversations, and a massive hit of endorphins.
🎒 What to Bring
Trail or standard running shoes (The light trails are very forgiving, so regular road shoes work just fine if it’s dry!)
Your own hydration/gels if you need them (there are no official SPA water stations out here, folks!).
Post-run vibes: We can grab a coffee or a cold drink at the Drohme melting pot right after we finish.
Summer Jam at Parc de Forest
Bring your instrument for a chill afternoon in the sun. We usually set up a blanket on the hill near Bar du Matin. See the geo-location pin of the event :)

How to Take Control of YOUR Mental Health
It’s time to take control of your mental health. How do you get rid of stress, anxiety and uncertainty? These emotions are buried deep in your reactive mind.
Find out what the reactive mind is, and in the process find yourself.
Here is the secret of being positive and free:
Thinking positively is not enough.
You also have to get rid of the negative thinking.
Your mind is like a garden.
You can plant many beautiful flowers in it, but if you don't get rid of the weeds when you plant your flowers, the weeds will soon take over the whole garden.
A positive thought is like a flower in your mental garden, and a negative thought is like a weed.
You cannot expect to have a positive mindset if you continue to have negative thoughts dwelling and growing there.
So, how do you get rid of the negative thoughts? That's what this Meetup is all about. Attend this local meeting and find out!
The Meetup event will be led by a consultant who had helped many people live happier in life.
Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there.
This group is created by the Dianetics & Scientology life improvement center.

No pressure and no experience required—just an interest in learning and building.
