Note: The warehouse location is in the alley behind 1502 Mt Vernon Ave. Enter through the gray door next to a roll-down garage door. If you drive to the location, be sure to park in the street, not in the alleys or parking lots surrounding the warehouse. And wear clothes you don't mind getting dirty with bicycle grease! Please be aware that volunteers under 18 need a parent or guardian to accompany them to their first volunteer experience and sign a liability waiver, while volunteers under 16 need a parent or guardian to accompany them at all times while volunteering with Vélocity.

**THE POWER OF THE SUBCONSCIOUS OVER YOU** You are welcome to arrive 15 minutes early for refreshments! At the lecture "The Power of the Subconscious", the speaker will clearly and understandably explain topics such as: What is the exact definition of the Subconscious Mind? How does it inflict unwanted feelings and anxiety in you? What determines how much pressure it exerts on a person? What exactly is the goal of the subconscious? This is not just a lecture where you sit quietly and listen. It's interactive and LIVE, so you can ask questions at any time. And the most important topic: **HOW DO YOU TAKE CONTROL OF YOUR SUBCOUNSCIOUS!** This group is sponsored by the Dianetics Life Improvement Center. CALL 202-797-9826 FOR FURTHER INFORMATION AND REGISTRATION

We will be open ONLY for volunteers who want to work on our donated bicycles OR if you have your own bike to work on. Everyone else will be turned away. Sorry but we want to reserve this time for fixing up bikes for our various upcoming community programs. Some help and guidance will be offered but be prepared to work mostly on your own. We want to give time back to all our hard-working volunteers who have been so essential.

Use the door labeled **“Arlington Cultural Affairs – Main Entrance.”** Ring the doorbell to be buzzed in.

I’ll be in the room about 20 minutes early to set up and meet folks as they arrive. If you can, please come a few minutes before the scheduled start time so we can kick things off together. *** Looking forward to laughing with you!

This is an opportunity for volunteers to support a professional mechanic as he guides customers working on their own bikes. If you know how to do some basic repairs, that's a plus, but even if you don't, you can greet customers and manage who gets helped next. Feel free to attend for only a portion of the time if you can't be there the whole three hours. Please note that this event is not usually an opportunity to learn about bicycle repair, since the mechanic tends to be very busy helping customers, especially during the warmer months. But it's a great way to contribute to Velocity, since almost all the funding for the volunteer program comes from the work done at the shops.

Come out if you just want to do a drop-in! All are welcome! Come out and be someone different than who you are everyday in life. Breaking out and discovering new ways of expression and interaction. And as always, drop-ins are at 10$/hr.

Want to mess with some electronics? Or perhaps contribute to HacDC's main group project? HacDC's latest event brings hardware projects to the community. We will focus primarily on the main project (Space Blimp!) but please feel free to bring some of your own projects to show off and work on!

12:45-345 in the Meeting Room, Library lowest level by the drinking fountain. Bring your yarn projects, meet new friends. Plenty of parking in the lot, in the overflow lot across the street, and on the street. See you there!

Whether you've never done improv before, or you've done it for so long you were quoted in *Truth in Comedy*, or anywhere in between, come join us! Swing by *Gresso's* for the **Columbus Improv Comedy Meetup**! The idea behind improvised comedy is to create entire scenes from scratch. A suggestion is taken from the audience and laughter is built on the spot. This can be done in game form, like *Whose Line Is It Anyway, Make Some Noise,* or *Wild 'n Out*; it can also be done in a longer way, to tell a complicated story, like *TJ & Dave*. Our meetup, which is central Ohio's longest running (and FREE!) weekly comedy event, brings the games for you to play in a safe, supportive, and compassionate environment. Afterward, many members will hang out in *Gresso's* itself and get to know each other. Not only is this a lot of fun, but you get to work on thinking faster on your feet, your public speaking, plus it's an excellent way to meet new people and build relationships that will last a lifetime, and you do that while laughing your butt off! Ask yourself if you want to join the **Columbus Improv Comedy Meetup**, and say "*Yes, And*" that you'll have a blast!

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.

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.
