***UPDATE: Meet us in the Rockville Library, Collaboration room #4*** ***Join us for an evening in an electronics lab where we will attempt to run clean scans of 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 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) Meet us in the Rockville Library, Collaboration room #4

Treat your children to GALita’s ***Séneca, ratón de biblioteca (Séneca, The Library Mouse)***, a bilingual play by Chilean playwright Jorge Díaz with original music by Iván Navas. Directed by Elena Velasco, this fun-filled play touches on the importance of reading and respecting differences, and runs March 14 through March 28, 2026. When a brainy library mouse meets a swaggering crew of street mice, sparks fly and stories take off—spilling from the shelves into a world of comic chases and big laughs. Along the way, unlikely friendships form and lessons unfold about listening, learning, and belonging. Brought to life through imaginative puppets and original music, ***Séneca, The Library Mouse*** invites young audiences to celebrate difference, delight in the joy of books, and discover confidence and pride in who they are—proving that brains, creativity, and curiosity can be just as powerful as bravado. **PERFORMANCES:** Weekdays from March 16-20 and March 23-27 at 10:30 am, and Saturday, March 14, 21, and 28 at 3 pm.

[Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **“Digital Device Detox,”** a guide to breaking free from the addictive and destructive powers of social media and apps, with Jillian Tucker, licensed clinical social worker in private practice, adjunct professor of clinical social work at Columbia University and New York University, and therapist with nearly 15 years of experience in addiction treatment and behavioral change. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/northern-virginia-digital-detox](https://events.ticketleap.com/tickets/profsandpints/northern-virginia-digital-detox) .] Many of us have had the same experience: We’re trying to get things done and stay focused on the positive in our lives, but we can’t stop looking at a cell phone that tells us that we live in troubled times, that everyone else is better looking and having more fun, and that escape awaits in the worlds of Candy Crush or Pokémon Go. Maybe it’s time to find effective ways to loosen the grip of that cell phone and rediscover the happiness that comes with using digital devices less. Join Jillian Tucker, who previously has given several excellent Profs and Pints talks related to mental health, for a crash course on how to restore balance in your relationship with digital devices to ensure they’re simply tools you use rather than instruments through which other people use you. She’ll start by discussing social and mental-health trends connected to the use of digital devices. We’ll delve into the specific ways that their overuse can be biologically and psychologically harmful and leads to division, depression, anxiety and anguish on an individual and societal level. Professor Tucker also will look at why digital habits are hard to break, citing neuroscience and what we know about behavioral addiction. You’ll learn the many ways in which devices and apps are deliberately designed to be hard to stop using. You won’t be urged to just chuck your cell phone, though. After all, such devices can keep you socially connected, be sources of joy and learning, and even save your life if you need to summon help in an emergency. Instead, we’ll look at effective strategies for reducing digital device use, considering approaches that treat the overuse of such devices as “addiction” but moving beyond them to consider more nuanced ones as well. We’ll explore how to find our core motivation to change and how to carry out a change plan. We’ll consider how those who failed in past attempts to reduce digital-device use can overcome impasses in their effort to change their behavior. We’ll discuss ways to minimize the feelings of inconvenience and withdrawal that might come with reducing digital-device use, and we’ll discuss strategies for regaining the social skills and reviving the in-person strategies that our device use had compromised. You’ll learn how the same conditioning and power of habit that got us using our devices so much more also can be harnessed to help us use them much less. You’ll learn how to curate and enhance the positive aspects of digital devices, to help maintain them as a source of connection, joy, humor and learning and keep them from causing you unhappiness or stress.

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 **Abstract** Web Forms gave .NET developers a powerful abstraction for building reusable UI controls long before design systems were a thing. Web Components finally bring that same idea to the browser natively. This session explores how the Web Forms mindset translates into Custom Elements, Shadow DOM, and HTML templates. We’ll examine how Web Components enable design systems that work across frameworks, how they differ from server‑driven controls, and why they’re becoming a foundational layer for modern UI. Whether you’re maintaining legacy apps or building greenfield projects, you’ll leave with a practical understanding of how to apply familiar patterns in a modern, standards‑based way. **YouTube Link** TBA
