​This meetup is for anyone building with OpenClaw (& Claude Code) or experimenting with other AI tools to create agents that can act and make decisions on their own. If you haven’t tried these yet, come hang out, ask questions, and see what others are building. We’ll trade notes, troubleshoot setups, and explore what it takes to run these systems openly on the web instead of inside closed platforms. Bring your laptop, grab some power, and jump into a night that feels part LAN party, part live build session, where people test ideas and show what their agents can actually do. 👉 [RSVP on LUMA](https://luma.com/53dx7no1) We’ll also have some fun by running a live test to see if a few of our agents can send Bitcoin back and forth and talk about why that’s a meaningful step for autonomous AI. It’s a chance to connect the dots between open AI tools, Bitcoin, and the wider goal of creating technology that no one can turn off. 👉 [RSVP on LUMA](https://luma.com/53dx7no1)

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.

***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
