***In Person Location:*** Rockville Library, second floor meeting room (Collaboration Room 4). 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! We've identified a flawed powerline component we, if it comes soon enough we will solder it in, and troubleshoot downstream electronics to see if any other components are busted (following a wiring mishap). We've had this component 'blow out' before and fixing it then we sufficient, so hopefully we get lucky again. The component however is currently very delayed, so until that comes we might need to focus on a backlog of documentation development. 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 4). To Join Virtually: https://meet.jit.si/mocomakers

[Profs and Pints DC](https://www.profsandpints.com/washingtondc) presents: **“Robert Frost’s Winter Poems,”** an exploration of a beloved poet’s thoughts on the season, with Michael Manson, former lecturer on literature at American University and past president of the Robert Frost Society. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://www.ticketleap.events/tickets/profsandpints/hill-center-frost-poems](https://www.ticketleap.events/tickets/profsandpints/hill-center-frost-poems) .] “Whose woods these are I think I know. His house is in the village though; He will not see me stopping here To watch his woods fill up with snow.” So begins “Stopping by Woods on a Snowy Evening,” which ranks as one of the most popular American poems of the 20th century and helped cement Robert Frost's status as of one of our nation’s most beloved poets. Come to the Hill Center on Capitol Hill as we approach the darkest evening of the year for a talk that will have you delighting in Frost and embracing the arrival of winter. Winter challenges modern urban Americans less immediately than it did Frost, who owned several New England farms. Yet the questions Frost raised through the metaphor of winter remain vital. Are humans meant to live and thrive on this planet, or is existence some cruel joke? How do we explain human resilience, the ability to keep pushing through despite the odds? Is there some force above us, in life itself, or some stubbornness at the heart of being human? What does it mean to thrive? Frost raised questions like these in his poetry without answering them. For him, the answers are to be found in the process of making. Whether we’re writing poems, keeping gardens, playing sports, building careers, or raising families, we are all turning chaos into order. In all pursuits, Frost said, “strongly spent is synonymous with kept,” and he is inspired by those times when humans spend their lives strongly and thus keep them. Be on hand as Michael Manson, a veteran scholar of Frost, reads and discusses Frost's poems on winter and other subjects. He’ll cover some of Frost’s best-known poems—“Stopping by Woods,” “Desert Places,” “The Wood-Pile”—as well as lesser-known works such as “Afterflakes,” “Questioning Faces,” and “Good-bye and Keep Cold.” The experience will be magical, and you’ll end up with a different perspective on the season ahead.

Mental Health, how do you understand it? How can you improve it? How do you get rid of stress, anxiety and uncertainty? These emotions are buried deep in your reactive mind. Find out what the reactive mind is, and in the process find yourself. Have you ever suffered from a traumatic experience, a deep loss or been through a painful breakup? Has your ability to communicate suffered as a result? And after that, even though you "moved on" did you find that things were never quite the same? Have you ever looked at childhood photos, or reminisced your early life and wondered where that happiness and spark went? Are your emotions out of your own control? Have you ever felt, even if you aren’t aware of it, that possibly you are getting in your own way of your happiness and success? How does this affect your self-confidence? Find out what is at the root of all stress, anxiety, depression and self-doubt. Find out how and why you hold yourself back from achieving your goals and having the life you have dreamed of. As soon as you learn what is at the root of these unwanted conditions, you’ll see it is something you can DO something about. You will not be labeled or categorized at this MeetUp. This group is hosted by the Dianetics and Scientology Life Improvement Center of Central Ohio.

Join us as we get the New Year started with one of the best films of the year: THE SECRET AGENT! This political thriller from Brazil is set in 1977 where a man flees from a mysterious past and returns to his hometown but soon finds the city is far from being the refuge he seeks. Here’s a description, trailer and plan for this event: DESCRIPTION: In 1977, a former professor flees from a mysterious past and returns to his hometown of Recife in search of peace. He soon realizes that the city is far from being the refuge he seeks. The film stars Wagner Moura, Carlos Francisco, Tânia Maria, Robério Diógenes, Maria Fernanda Cândido, Gabriel Leone and Udo Kier in his final film role. TRAILER: https://www.youtube.com/watch?v=9UfrzDKrhEc BUZZ & ACCLAIM: The Secret Agent was the most awarded film at the 2025 Cannes Film Festival where it won Best Actor for Wagner Moura, Best Director for Mendonça Filho, the Art House Cinema Award and the FIPRESCI Prize. At this year’s Golden Globes, it became Brazil’s first film ever to be nominated for Best Film (Drama)! It also received a Golden Globe nomination for Best Foreign Film, a Best Actor nomination for Wagner Moura and was selected as Brazil’s entry for Best International Film at this year’s Academy Awards. The film is receiving an incredible 99% positive rating on Rotten Tomatoes where critics say, its “compelling script, impeccable acting, and striking 1970s aesthetic” make it “impossible to look away!” Critics say The Secret Agent is “one of the few standout movies of the year” and the Chicago Tribune calls it a “masterpiece of a film” and “the best film of the year!” PARKING: Close, convenient parking is available in the nearby garage (located between 9th and 11th, just off High St). Bring your ticket with you and have it validated at the theater and for $2, you’re covered for the night! PLAN: We’ll plan for a 7pm-ish showing and will meet in the lobby area about 30 minutes before showtime! With this being a limited release film, we’ll tentatively plan to see it at the Gateway, but location may change based on where it is showing and the showtimes available. Once details are confirmed, advance ticket is advised. Once you have yours, please list your seat number in the Comments section of this event. Showtime, location and complete details will be confirmed and announced as the date gets closer. Happy New Year and look forward to seeing you there, Dan
