Today we are Steve's Lab. RSVP and you'll be sent the location. It's in Silver Spring. ***Join us for an evening in an electronics lab where we will attempt to run clean scans of graphene and gold samples, and then clean up that data with post processing.*** This is a high sensitivity experiment, and we do not plan on being successful so early. But we've had promising results lately - so we will be putting in the time. We are NOT meeting at our usual location, but rather at Steve's house/lab. If you RSVP, you will get a DM with the address but it's located in Silver Spring. We will attempt full, clean lab - clean tip repeated scanning tests to see what we can learn and improve. We will experiment with online attendees, but if all possible showing up in person is strongly encouraged. Online join link is: - [https://meet.jit.si/mocomakers](https://meet.jit.si/mocomakers) Our community is building (and documenting for other teams) how to build a scanning tunneling microscope using a mix of common and 3D printed parts. This will allow us to scan and visualize a single atom - an ambitious we are doing over the course of a few months. The MoCo Makers community is one of the most innovative and competent groups in Maryland, and we've done everything from [publishing cancer research](https://pubmed.ncbi.nlm.nih.gov/38136356/), to [launching products](https://www.kickstarter.com/projects/gotim/cozy-curvy-multi-contour-pillow), [winning grants](https://covidinfocommons.datascience.columbia.edu/awards/2014255), and inspiring thousands. Now our biggest challenge yet has appeared. We are building a Scanning Tunneling Microscope, that will allow us to scan and visualize single atoms. To get a better idea of what we are doing, see our reference project here: [https://www.youtube.com/watch?v=7N3OqTEq08g](https://www.youtube.com/watch?v=7N3OqTEq08g) All starting CAD, code, and reference files should exist. However, let's be the first Maker community to document the build process and share it with learners around the world. We will be publishing our work here -[ https://hackaday.io/project/202816-qt-panda](https://hackaday.io/project/202816-qt-panda) If you need a ride, let us know.

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!

We will answer your questions about Zen practice, how to find support, and how to create a daily home practice.** ***When we start Zen, we "empty the bowl" and become open and free; we become "teachable." In Zen, we practice simple awareness and mindfulness of actions. We become responsible to our lives, to live a path of goodness and truth. Any faith tradition can practice Zen.*** **After the class, you will join us for our group meditation at 7 pm for one 25-minute period --or until we end at 8:30 pm.** **The class will be held in our Zendo, lower level entrance at the back door of the church.

Socrates Café meets twice a month. Though this may be considered a "philosophical" group, there are no rules as to what is discussed. Usually, the topics revolve around social concerns, morality, and the first principles of things. Prior to each meeting we vote online for the questions we will discuss. That way, we will have enough time to ruminate on them and have more in-depth conversations. If you RSVP to a meeting, you may post your question in the event comments section below. I'll send out a survey for voting a few days prior to the meetup. We discuss two questions each night. So you will get to cast two votes in the survey. When we meet, we break into smaller groups of five to seven to discuss the top two vote-getters. Each group discusses one question for around 45-50 minutes, and we then take a short break. After reconvening, each group moves on to its second question. Hope to see you there! -Brian

NFT's are here to stay folks!

**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.

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.

You can sleep in on the Sesquicentennial (observed), we’re shifting to the following Friday. But join the local UX community for a chat and some biscuits to catch up. If you were in CA for Figma Config, tell us all the lines and you can tell me how I can animate an SVG without coding it by hand, and why I’d even want to. Thanks to the team at Nationwide of supporting the group.
