These are our regular Monday evening electronics nights. Everyone from absolute beginner to experienced is welcome. These evenings are not classes or tutorials, rather a very friendly informal evening. We have a wide range of people who come. Some are absolute beginners who do not even work or study electronics, but are interested to know more. Others have something that they are already working on. We almost always have some first time visitors and we always give them a tour of the space. Come in with your Pi, Arduino, or whatever you have. Bring your laptop. Maybe you want to make something, solder, breadboard or use our electronic gear. Maybe you have some vague ideas and just want to get started. Or maybe you’re just curious……if so, it’s fine to come along and just see what others are doing. If you would like to get even more involved and have the full use of our space, we would be delighted to have you as a full member. Membership brings many benefits. We are located behind Mr Price and the Bright Lights store on Kylemore Road. We have lots of free parking available.

**Do you like to make things? Would you like to use 3D software, lasercutter and 3D printing to help you make your idea?** TOG has an open evening to learn how CAD software and 3D fabrication tools can help you make your project. All you need to take part is your own laptop and some ideas on what you want to make. This is not a taught class, more like an informal working group of self-directed makers. We will be happy to help you explore how to use our 3D tools in designing and making your project whether you are a crafter, designer, engineer or hobbyist. Come and have a look at the tools in our space and get some ideas on how your project can be made.

Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs. This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context. We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!

**Total Eclipse of the Chart: School Redistricting Dashboards** In this presentation, we will explore the utilization of maps, sets, and SQL within a Tableau dashboard to help provide “what-if” analyses generated through the use of a mapped dashboard, providing different scenarios and the potential implications of these. While in this use case we are focused on a large school district, the concepts of utilizing existing data to explore the future impacts of modifying different geographic boundaries can be useful to many industries, balancing the mix of maps with visual analytics. **About Our Speaker** Robert Kramer is the Data Systems and State Reporting Coordinator at South Western City Schools in Grove City.

Join us for a practical, beginner-friendly guide to choosing the right large language model. We’ll compare major models like ChatGPT, Claude, Gemini, and Llama, talk about when to use hosted APIs versus local models, and break down the tradeoffs around cost, speed, quality, privacy, context windows, coding ability, and reliability. You’ll leave with a clearer mental model for picking an LLM based on your actual use case instead of hype, benchmarks, or brand names. No deep AI background required. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** TBD **YouTube Link** TBD
