***In Person Location:*** Rockville Library, second floor meeting room (Collaboration Room 3). Will recreate our Preamp circuit board inside EasyEDA to make it shareable for others. This ideally will also allow us to finish up design enough to submit for a materials grant program. We are experimenting with a new virtual join link - [https://meet.jit.si/mocomakers](https://meet.jit.si/mocomakers) If you can make it in person, that's always recommended! Let's resume repeated full end-to-end testing cycles and continue to iterate our design and resolution. We are getting close. 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. Does it sound hard? Perhaps.. However! I have every confidence that we are now operating at a level were we can take on this mean, cross-functional project. We continue to build on our past successes, and a key technology we previously applied was increasing the signal of small voltages using OpAmps - which we did during our custom pH Probe project - [https://www.mocomakers.com/ph-probe/](https://www.mocomakers.com/ph-probe/) \- That technology is exactly what we need to get this machine working\, and at a high precision\! 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 have a bit over $2,000 in materials costs, so if you want to sponsor this project, and get banners at events with 20K attendees, and access to our email broadcast of 30K members, please contact matt@mocomakers.com We are also open to university, lab, or community partnerships so feel to reach out if you want to be part of this project. Together, we can do incredible things. ***In Person Location:*** Rockville Library, second floor meeting room (Meeting Room 3). To Join Virtually: https://meet.jit.si/mocomakers

Join us and become a founding member of this amazing community!** **Very limited seating. In-person only.** **Make sure to RSVP today to reserve your spot.** **When: April 16, 2026 @ 5:45pm-9pm EST** **Where: 11710 Plaza America Dr #710, Reston, VA 20190** The Cash-Flow Breakfast Club is NOT just a meet up. It’s the most unique Real Estate Investor Community of Mentors, Coaches & Masterminds. A community of growth oriented, abundance mindset, go-giver individuals with a BARE MINIMUM commitment to become financially free through real estate investing. We focus on providing education and building networks to help every member solve their cash-flow freedom equation, so they can have the time-freedom needed to follow their passions, make a lasting impact and even change the world! The unique format of this event, which consists of high-level education, gamified networking, mastermind breakout sessions, case studies, group deal analysis, market deep dives, and peer-to-peer coaching facilitation makes this the most impactful local real estate investor group a real estate investor can be a part of. The foundation of the group is built around the belief that everyone in the room has the potential to change the world… however most of us never have the time, energy or financial situation to even dare to dream big enough. Most of us have passions that will never be followed, amazing businesses or ideas that will never be pursued… unless we can solve the Cash-Flow Freedom Equation, which ultimately leads to Time-Freedom. Once that happens it is usually much easier for us to think bigger, dream bigger, be bigger. · 🤯 Learn more about the Cash-Flow Breakfast Club [HERE](https://cashflowbreakfastclub.com/) · 🥇 Get in the VIP List to be notified about the next event in your area [HERE](https://the.cashflowbreakfastclub.com/VIP) · 🤙🏼 Learn more about Launching your own Cash-Flow Breakfast Club Location [HERE](https://cashflowbreakfastclub.com/launch-your-own-club/) · 🤝🏼 Learn more about becoming an Affiliate-Sponsor at one of our club locations [HERE](https://cashflowbreakfastclub.com/affiliate-sponsors/) · 📷 View photos and videos of some of our recent events [HERE](https://cashflowbreakfastclub.com/about-the-cash-flow-breakfast-club/) · 😎 Looking to represent?

Welcoming back Kecia Deveney for our annual Creative Minds Summit! This mixed media journal is a place for fragments. For what was saved without knowing why. For scraps, thoughts, images, and moments that did not ask to be finished. Nothing here needs to make sense. Nothing here needs to be useful. These pages are allowed to change, to be returned to, or left behind. This book belongs to the act of keeping. In **A Place for Fragments**, you’ll learn how to create a soft, fabric-covered journal using scraps and remnants using cardboard as our substrate; simple, forgiving binding and stitching methods; ways to layer paper and fabric without planning or pressure; how to let materials guide decisions instead of rules; how to work intuitively and trust when something feels complete enough; simple ways to work on inside pages and making an image focal point using resin.

Title: Foundations of Localized Symmetry Mathematics Date: April 18 2026 Noon - 14:00 EST Summary: The moment you use Euclid’s definitions of points and distances in any of your mathematical axioms, all that follows is assured to produce some level of nonsensical results when applied to the foundations of physics. The reason is not complicated: Euclid’s definitions are deeply mired in accepting as a “given” the very concepts that emerge only in well-defined inertial frames, which in turn are local instances of symmetries that are always finite and context dependent. In this talk, Terry will discuss how reframing mathematics in terms of symmetries that, as in the real world, are finite, composite, and dependent on self-observation (acceleration), results in a richer and far stranger set of mathematics in absolute conservation of quantum numbers generate local and global symmetries — the opposite of Noether’s theorem — that in turn create the emergent classical phenomenal such a particles, fields, space, and time. Speaker: Terry Bollinger is a computer scientist with BS, MS, and professional degrees from the Missouri University of Science and Technology.

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. This session will be at the Worthington Park Library in the Olentangy Meeting Room.

The topic for April is "Water" Speak Easy: true stories, told live. The idea is simple: an audience, an open microphone, and great stories. Hilarious, gripping, poignant- it's up to you. Audiences are invited to come to listen or come to tell as folks from all corners of Columbus offer their stories live on stage! Held at Wild Goose Creative's warm, intimate space, this night of tales occurs on the 3rd Thursday of every month. Doors open at 6:30 pm, show starts at 7:00 pm. Please arrive early if you want to tell, as we generally only have room for a limited number of tellers, and the sign-up sheet has a tendency to fill up fast. Formed around the idea that people need stories--they're what hold and draw us together--SpeakEasy celebrates the strangeness and commonness of being human. And in a world of smartphones, Facebook, Twitter, and more . . . it gives people a real, breathing, in-person way to connect. The night is geared for true stories of all kinds, taking the best tales told around kitchen tables, in darkened pubs, on the street corner, and at late-night parties and giving them an audience. Speak Easy is also a great outlet for performers, writers, and artists looking to share their favorite stories and perfect their skills. We strongly encourage tellers to please tell the story rather than read it so we keep within the spirit of good storytelling and stay engaged with the audience. All are welcome. Hang around after the show for a drink and build community!
