Engineers Without Borders

Interested? Contact Preston Moore k.preston.moore@gmail.com 614-300-5989 ———————————— Engaging in men’s work is the new way to forge friendships while being open-minded to personal growth. Many men experience healthier relationships, personally and professionally, by engaging in this work. Open Men’s Group is a container for men to share vulnerably without receiving judgment or feedback. We believe that emotionally mature, powerful, compassionate, and purpose-driven men will help heal some of society’s deepest wounds. We support the powerful brilliance of men and we are willing to look at, and take full responsibility for, the pain we are also capable of creating – and suffering. We care deeply about men, our families, communities, and the planet. Visit ManKind Project USA to discover more. https://mkpusa.org/

Most people use LLMs by feel: ask a question, read the answer, decide whether it “seems good,” and move on. That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable. In this talk, we’ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. We’ll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork. This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it. We’ll cover: * Why “it looks good” is not enough * How to improve prompts by changing the input, context, and constraints * How to compare LLM outputs more systematically * Basic evaluation techniques for accuracy, consistency, and usefulness * How embeddings, cosine similarity, and scoring can help evaluate results * Where automated evaluation works — and where humans still need to stay in the loop By the end, you’ll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve. 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.

Some trained COUNT volunteers work together once a month at RMH (http://www.rmhc-centralohio.org/volunteer.php) as Housewarmers (usually on the 1st Sunday from 1 – 5 PM). Some schedule other shifts at their convenience. You may try this out with less fuss by following a "Fast track" or go through the normal process. Fast track • Arrange a time to shadow a COUNT volunteer. Call Dave Nohle at 614-268-9558 (cell). • Show up and try it out. • Complete application, etc. later. Normal process • Complete an online application (http://rmhc-centralohio.org/volunteer/). • Attend orientation in advance. • At orientation you will complete forms agreeing to keep family/patient info private and allowing a background check and tour the facility. • Complete one training shift. Daily shifts are: morning 9 AM - 1 PM, afternoon 1 - 5 PM and evening 5 - 9 PM. • Schedule shifts online using the on the RMH scheduling system (http://www.volgistics.com/ex/portal.dll/?FROM=32895). The Ronald McDonald House (RMH) provides housing and meals for families with sick children. The Columbus RMH is the largest in the world with 137 rooms. COUNT has been volunteering there since May 2014. Housewarmers work with RMH guests to provide a home-like environment - greet, assist with family needs, answer phones, give tours, assist with checkin/checkout, prepare guest rooms after checkout, clean facility, laundry, restock supplies and staff the front desk. RMH Housewarmers volunteer at least one four-hour shift a month. All Housewarmers must complete an application and agree to a background check before they can be full fledged volunteers.

Open Shelter has teamed up again with Red White and Boom! Friday, July 3rd & we are looking for volunteers to run the event’s alcohol booths. Proceeds from sales go to the Open Shelter’s organization. There are two available shifts: 12-6p & 5-11p. There will be an ipad-like device to process transactions in addition to cash. Everything will be in bottles or cans, so transactions should be very easy. Must be 21+. There are multiple beverage stations along the Civic Center Bridge. The stations are covered and also have beverage trucks next to them, so volunteers can cool off in the trucks. As far as parking, it is suggested those who are coming from the east use the Columbus Commons Garage, and those from the west use the Belle Street Garage. Harry from the Open Shelter will be your contact.

Gardening for Butterflies Talk and Walk with Butterfly Ridge Saturday, July 18, 2026 Join Chris Kline from Butterfly Ridge for a presentation on gardening for butterflies and a walking tour of Infirmary Mound Park, looking for butterflies, discussing their importance, and how to make butterfly-friendly improvements to residential landscapes. Meet at the James Bradley Center. Christopher Kline’s interest in butterflies began in 1997 when he began tagging Monarch butterflies in Indiana. Since 1997, he has tagged thousands of Monarchs, co-founded the Central Arizona Butterfly Association, and founded the Southwest Monarch Study. He has also served as the Butterfly Specialist at the Franklin Park Conservatory and Botanical Gardens in Columbus, Ohio. He now is the Director of Butterfly Ridge Butterfly Conservation Center in Rockbridge, Ohio where he and his wife have converted 21 acres of fields and forests into butterfly friendly habitats and have quintupled the butterfly population in the process. He has authored several books including A Field Guide to Tropical Butterflies of American Conservatories, Butterfly Gardening with Native Plants, Butterfly Rider, Moths of Butterfly Ridge, and the Beginner’s Guide to Mothing.

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.
