Hi Everyone, This is our weekly open hackerspace evening! Usually from 19:00 :-) Feel free to drop by, come and nerd with us! See this Tuesday! We're in room 126, ring the room number and we'll open the door. We're located on the first floor

Give your still good laptop a second life instead of ditching it because Windows 11 says it is no good... Or you heard Linux is cool. If you have a backup of your data, that is great, else indicate that you do not, so we can help you. Do so in an extra message or to m10@m10tech.nl, else I don't receive your information. Geef je laptop die het nog prima doet een tweede kans in plaats van hem af te schrijven omdat Window 11 dat zegt... Of omdat je hoorde dat Linux gaaf is. Als je al een backup van je data hebt gemaakt is dat perfect. Of verwacht je dat wij dat doen? In dat geval graag aangeven hoe vol je harde schijf nu is... Doe dat in een extra bericht of aan m10@m10tech.nl, want de info komt anders niet door.

Let us meet, have a coffee and code together, or just discuss :)! This Meetup is everyone that considers himself "Techie", in the broad sense and wants to socialize :). Join us and chat, ask your questions, or work on your own projects. The choice is yours! There is no agenda, this is simply a gathering of interested folks :). We're meeting at Lebkov right inside the Utrecht Centraal station. We're typically sitting at the large table. Search for the folks with the laptops in the back! You are very welcome to join whether you are an experienced developer, or simply interested and want to chat!

Geen (geplande) workshops of lezingen, maar mocht je iets leuks te melden of te leren hebben voel je vrij om dit te delen. Of kom gewoon gezellig langs om mede-bitcoiners te ontmoeten bij deze Eenentwinting Utrecht meetup bij dimS Eten en Drinken in Amersfoort (op loopafstand van Amersfoort Vathorst).

Ready for a scenic hike? We’re heading out for a beautiful 19 km hike around Lunteren, passing forests, sand drifts, and even the official geographical center of the Netherlands. Expect beautiful nature, good conversations, and a great way to meet new people! 19 km is also a perfect first training day for the [PLN charity walk](https://www.meetup.com/nijmegen-explore-and-more/events/313573496/). And you’re of course also absolutely welcome to come if you’re not joining the fundraiser. Come for the nature, the social vibe, or just because you enjoy a solid hike. **What to expect** 📍Distance: \~19 km 🌲Terrain: mostly forest paths, sandy sections and heathland (varied and scenic) 🚶**‍**Pace: relaxed but steady ☕Breaks: there are some nice spots for a couple of breaks **Times & places** ⏱️**12:15** Start at [Lunteren train station (Spoorstraat 4, 6741 DE Lunteren) ](https://maps.app.goo.gl/6uPDXGh8ATBDJJQe9) 🏁**17:00** Back at starting point (estimate depending on pace and breaks, flexibility helps) **Cost** 💰[A €7.50 donation](https://www.detikkendeklokchallenge.nl/fundraisers/sam/donate) (or more 😉) to the PLN fundraising walk. Prefer to donate via a payment link/iDeal, or cash? Just send me a message! 🎗️This event is free if you have already signed up for our team in the [PLN fundraising walk](https://www.meetup.com/nijmegen-explore-and-more/events/313573496/) ❤️‍🩹The brother and mother of one of my best friends have been diagnosed with PLN, a genetic heart condition. This disease still has no cure and crucial research is at risk of slowing down as international funding becomes uncertain due to the changed political climate. That's why we are trying to raise funds, so this very important research can continue. **Preparation** 🥾This is a friendly training distance, suitable if you’re comfortable walking longer routes. No speed needed, just a positive mindset. 🥪Bring water, snacks, weather-appropriate clothing, and comfortable shoes. ❓Questions? Send me a message, happy to help :-) **Event Policies** ⚠️ Disclaimer: Participants are responsible for their own safety. Please stay with the group and respect nature at all times. ⚠️ Cancellation: The event will be canceled in case of severe weather conditions (you’ll be notified in advance). A refund is not possible because this is a fundraiser, the money goes directly to a good cause. But I will try to reschedule a worthy replacement event :-) ⚠️ No-show might result in ban: Marking yourself as "going" takes a spot away from others for limited capacity events like this. If you are marked as going but don't show up, you might be banned from the *Nijmegen Explore & More* group

Join us on a 7km hike from Amersfoort Vathorst train station to Landgoed Hoevelaken and back. From Vathorst Station we'll walk through a residential area for around 15 minutes until we'll cross under the A28 highway and head into Landgoed Hoevelaken. Here we'll walk on a mixture of long forest lanes and smaller winding forest paths. After crossing the provincial road to Nijkerk we'll also walk through the Overbos forest. At the end we'll head back to Vathorst train station via Nijkerkerveen village, some meadows and along the railways. Utrecht Hiking Community is organising one hike per month. Our aim is not to hike fast, but to hike "gezellig". It's intended to be a mixture of being active in nature, exploring places in and around Utrecht and meeting fellow hiking enthusiasts. Everybody is welcome to join, no matter whether you are a beginner or a hiking pro, expat or a local, student or professional (or maybe even retired). Also you can come with friends, but alone as well. At our previous hikes there were always many people who didn't know any of the other hikers, so it's a perfect opportunity to get to know some fellow hiking enthusiasts. If you like this idea and want not only to participate but to support us as well, you can help us by making a small donation using this link: https://www.ing.nl/payreq/m/?trxid=L9Z0gDbAfY48ETP1VhKdTHId88RaaaDe We're using these to cover for our travel costs and MeetUp subscription (about €200 a year for event organisers). We'll start our hike at 10.30AM and will meet in the tunnel under Amersfoort Vathorst train station. Please try your best to arrive on time, since if you arrive later, we won't make the whole group wait for you. You can however send a message on WhatsApp to +31621177691, so we can send you our live location and you can try to catch up with the group. For those coming by car, there are a few parking places at the end of the Amendijk street in Hooglanderveen, which are directly next to the train station. At the nearby Vathorst shopping center there are many more free parking places. After the hike, after arriving back to Vathorst train station, we can go for a lunch with anybody who wants to in the nearby Vathorst shopping centre. What should you bring for this hike? Good hiking shoes (about half of the route is paved and the other half is unpaved), a bottle with water or anything else you'd like to drink on the way and of course a good mood are the only things really necessary. Also don't forget to put on some SPF. A few other practical things that are good to know: Dogs are allowed on this route, but need to be kept on a leash while we are not walking in Landgoed Hoevelaken. There is no toilet at Amersfoort Vathorst train station, so please make sure to visit a toilet before you depart to Amersfoort Vathorst. Alternatively you can go to the toilet in the library in the Vathorst shopping centre, but it's a 3 minute walk from the train station to get there. We will make some photos during the hike for on our social media (Instagram: @utrecht.hiking.community). If you don't want to be on any photos, you can still join, but please notify the organisers before the hike. And finally, in case of very bad weather we might postpone the hike to another date. Right now it doesn't look like we may expect that kind of bad weather, but just for in any case, please check this event for any updates on the evening before the hike. See you on Saturday!

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.

Feel free to work alone, pair up, attend one of our workshops/presentations, or mingle!

The only Metro Park with a fire tower! **History** [Scioto Grove Metro Park](https://www.metroparks.net/parks-and-trails/scioto-grove/) officially became the 19th park in the Columbus and Franklin County Metro Parks system when it opened to the public on May 6, 2016. Located along a scenic bend of the Scioto River in Grove City, just south of Columbus, the 620-acre park was designed to blend preservation with modern recreation. Long before it became a park, this river corridor served as a vital footpath and trade route for Indigenous communities. Decades later, the mature forests and dramatic river bluffs caught the eye of conservationists looking to expand regional green spaces. The grand opening was a major milestone, drawing over 19,000 visitors in its very first weekend. The creation of the park was made possible through a sequence of land acquisitions and strong community partnerships. In October 2009, Franklin County voters approved a critical property tax levy that funded the initial purchase of 66 acres. Shortly after, the City of Grove City generously donated nearly 193 acres of land, previously known as Talbot Park, to anchor the project. Additional parcels were acquired using state grants from the Clean Ohio Conservation Fund, successfully closing the gap between properties by December 2012. This collaborative funding model ensured that pristine wilderness areas remained completely protected from commercial development. From its inception, the park aimed to introduce innovative amenities to the regional park system, most notably the concept of "urban backpacking". Through a key partnership with the outdoor gear retailer REI Co-op, the park established the scenic REI River Trail. This trail features five rustic, reservation-only campsites along the river, specifically designed to give newcomers a safe place to practice backpacking close to home. Additionally, planners prioritized making the park fully pet-friendly, allowing leashed dogs across all trails and areas. This open-pet policy uniquely distinguished Scioto Grove from many other traditional Columbus Metro Parks. As the park grew in popularity, community members established special commemorative landmarks to honor local lives. In June 2019, a dedicated memorial garden was unveiled near the park entrance in memory of Reagan Tokes, an Ohio State University student. The serene space features a central pond bordered by bright blue flowers, representing her favorite color. A primary buckeye tree stands alongside a dedicated plaque, surrounded by four additional buckeye trees to represent her immediate family members. This addition transformed a portion of the park into a meaningful place for community reflection, healing, and peace. The historical depth of the park took a significant leap forward with the relocation of a massive piece of Ohio history. In August 2023, Metro Parks officially unveiled the Keystone Forest Lookout Tower, which had been carefully moved from Jackson County, Ohio. Originally constructed in 1942 by the Aermotor Windmill Company, the 82-foot-tall metal structure spent decades guarding southern Ohio’s vast forests from devastating wildfires. Workers painstakingly disassembled, re-galvanized, and reassembled the historic landmark at Scioto Grove. Today, visitors can climb its 111 steep steps to experience a panoramic view stretching all the way to the downtown Columbus skyline. **Map of the Park** Here is a [map of Scioto Grove](https://www.metroparks.net/wp-content/uploads/2026/05/SGR-map_1980px_2026.jpg). **Summary** We will hike around 5 miles on the Overlook, REI River, Mingo, and Arrowhead Trails. While the configuration of the trails can lead us to occasionally taking longer hikes than at other parks, Scioto Grove is not generally a very strenuous place to hike. If you use hiking poles and inadvertently forget them, this is not a park where you're likely to end up caring that much. That said, Scioto Grove is one of the better Metro Parks for hiking as well as other things. They are the only Metro Park with five camping areas where you can literally pitch a tent and sleep for the night. You must contact the park and reserve these in advance; they are however free. **Where We'll Meet** We'll meet at the Arrowhead Picnic Area, near the restrooms and playground. Arrowhead is the main picnic and parking area of the park, and it also has the only water fountain at Scioto Grove. **After the Hike** Afterward, we will head over to [Grove City Brewing](https://www.grovecitybrewery.com/) for [drinks and food](https://www.grovecitybrewery.com/menu). They have pretty good hamburgers. I was mortified to discover that I've never had their [Grove City Hooyah](https://www.beermenus.com/beers/486553-grove-city-hooyah) before, but I will correct that during this event. The actual address of the brewery is [3946 Broadway, Grove City, OH 43123](https://www.google.com/maps/place/3946+Broadway,+Grove+City,+OH+43123/@39.8836912,-83.0919635,16z/data=!3m1!4b1!4m6!3m5!1s0x88389b3a28d0f4ad:0x3d85c41f608406c6!8m2!3d39.8836912!4d-83.0919635!16s%2Fg%2F11g8dh6h1_?entry=ttu&g_ep=EgoyMDI0MTAwOS4wIKXMDSoASAFQAw%3D%3D). We should be there by 5 if you can't make the hike and just want to join us for drinks.

**Practical Curiosity: Learning from Everyday Data** How do we actually get better at utilizing our day-to-day data? Fancy dashboards and complex models might look nice and draw attention, but that’s not where most of us spend our time. In fact those shiny outputs frequently sit unused, while the real insights are drawn from the analyst’s daily practice. Sometimes it’s as simple and as powerful as noticing that a segment is shrinking, a channel is underused, or certain links keep getting all the clicks. There’s many different places that the spark of insight can come from, but you have to keep your head in the data and know where to look. In this session, we’ll explore real-world examples of how segmentation, testing, and click behavior can uncover practical digital marketing opportunities. You’ll leave with inspiration for your own use cases, along with a few simple ways to ask better questions, spot meaningful patterns, and make smarter decisions without overcomplicating it. **About Our Speaker:** [Elaine Armbruster](https://www.linkedin.com/in/elainearmbruster/) is a Director of Digital Experience at the [American Diabetes Association](https://diabetes.org/), where she focuses on using data and insights to create smarter, more effective digital experiences. A lifelong Columbus resident, she has built her career in email marketing and the broader digital user journey, and is finding she most enjoys working in the messy middle where systems, data, and big ideas don’t quite line up yet.
