TOG Watch Night: The Secret Life of Components (Tim Hunkin) We’re kicking off a new bi-weekly Monday Watch Night at TOG. We’ll watch an episode of Tim Hunkin’s “The Secret Life of Components” together, then have a relaxed Q&A and discussion afterwards. This is a friendly, low-pressure way to learn the kind of practical tips you normally only pick up through years of making, fixing, and building. Perfect for beginners, makers, repair folks, and engineers who enjoy the practical side of components and mechanisms. How it works \- Watch together \(one episode per night\) \- Q&A and chat after: questions\, examples\, tangents\, and “how would we do this at TOG?” \- If you miss a week\, no stress\. Watch it at home and come along to the next one First session \- Monday 26 January \- Episode 1: Chain \- Free and open to all \- TOG Hackerspace \(Dublin 12\, D12 CF6V\) Full details: https://www.tog.ie/2026/01/tog-watch-night-the-secret-life-of-components-tim-hunkin/

Join me for a swim on Monday 6th April at 1pm, Weather pending. All are welcome - newcomers and established members, swimmers, paddlers, and toe dippers. I recommend that you don't stay in too long, like me, this time of year, and stay within your dept. We look out for each other but we are not lifeguards. Bring warm clothes for after the swim as it's a bit cold this time of year. Meet in shelters in front of tower near sea Look forward to seeing you all there.

Join us on **Easter Monday, 6 April**, for a **Parks on the Air (POTA)** outing from **Ticknock** in the Dublin Mountains. If you have not come across POTA before, it is all about bringing amateur radio into the great outdoors, setting up in a qualifying park, and making contacts from the field. We did a quieter test run on Bull Island recently and it went well, so this time we are opening it up to the wider **TOG community and the public**. We will meet at **10:30am** at the **Ticknock café** and then head off to find a good place to set up and operate. We expect to be on air for around **two hours**. You are very welcome to come along, help out, and even have a go on the radio using the **club callsign EI0TOG**. Jeffrey Roe, **EI7IRB**, will be leading the activation. Jeffrey is planning to cycle out, but there is parking nearby too. If radio is not really your thing, or you do not want to stay for the whole activation, Ticknock has plenty of walks so you can still join us for part of the outing. After the POTA activation, there are also IRTS 2m and 70cm contests running, so anyone who wants to keep the radio fun going is welcome to do that too. As always, this one is weather dependent. If the conditions are awful, we will give it a miss rather than spend another Monday getting soaked. Read the full details here: https://www.tog.ie/2026/04/pota-on-easter-monday-from-ticknock/ We hope to see some of you there in person, or hear from you on the bands.

There is no workshop happening this bank holiday Monday (6th April), but we will be back next Monday (13th April) for more fun and games.

11 30 AM meet-up on top of hill. 🥾 Short uphill stroll (15–20 mins… spiritual growth disguised as mild suffering) At the top: • Glorious 360° views • Ancient stones & mysterious symbols • Deep meditation & possibly dramatic wind-blown hair • Profound insights (or at least a good excuse to sit down) Once suitably awakened, we descend and refuel like the grounded beings we are at Loughcrew Gardens. Bring comfy shoes, warm layers, and whatever level of enlightenment you currently possess. ✨ Side effects may include clarity, peace, and snack cravings ✨

***Introduction to Dublin Walking Tour! Join us on a history focused walking tour of Dublin city centre!*** Hi, my name is Marina Boyle and I'm a local tour guide and Dublin enthusiast! I hope to meet you on this special walking tour of our capital city. This tour is perfect for anyone new to Dublin, anyone living here and looking to make friends, or even locals who are just curious to learn more about where they live. Together we'll explore Dublin's main areas of historical significance, including O'Connell St, Trinity College, Dublin Castle, Christchurch Cathedral, and many more. I'll be taking you through all the historical facts and entertaining tales, with plenty of time to chat and make connections between stops as well. We'll start on O'Connell Street, easily accessible by public transport. Our meeting point is opposite the GPO and please note that we will start at 11:30 am sharp. The tour will last just under 2 hours. This event operates on a tip-based model, meaning that if you enjoy the tour, a tip of any amount is very appreciated. Please feel free to leave a comment if you have any questions! I am looking forward to meeting you :)

📚Reading books and discussing them are two distinct experiences! Conversations about books and sharing insights help us better appreciate literature and enrich our lives. Let's grab a drink (alcoholic or non-alcoholic) and discuss books we're currently reading or have recently enjoyed—whether poetry, fiction, or non-fiction. Bring your physical book or e-reader. There's no formal structure or agenda—just books and good conversation.💬 It's a perfect place to get book recommendations and rediscover your reading momentum if you've hit a slump. We welcome readers of all backgrounds and interests! ⚠️**Something Happened?** If something unpleasant happened to you, it may happen to others. Even if it seems minor, don't hesitate to reach out to me. 🔍 **How to find us?** * When I reach the venue, I'll leave a comment in the meetup where the group is seated. Normally, the booking is in my name, so you can ask the staff for the group. * If you're unable to find us, leave a comment in the meetup page. I'll be able to guide you. We highly encourage you to move between tables and strike up conversations with fellow book lovers. These discussions about literature and reading recommendations are often the highlight of the event! As an organizer, I'm always looking for feedback about the event and suggestions for new events, so feel free to suggest ideas to me. 💡 I look forward to seeing you all! 😊

Hello Everyone! Let's read something before coming to the event. It can be a few pages from a book, an article, a poem, an advertisement, a joke, a recipe, a quote, social media content - anything you find interesting. We meet and chat about it, as a starting point of conversation. Please feel free to bring books :)

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.

This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD

AI is changing how art is made. But when does it stop being your work and start being the machine’s? This month we're going to be doing a panel with with digital image, music, and written word artists, talking about at what point, while using AI in the creation process, does the work become not the artist creation? We encourage audience participation during this event that will be moderated by Chris Slee. Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus. Sponsored by [Transform Labs](https://www.transformlabs.com/services)
