• What we'll do On https://blackecon101.podbean.com/ Thursdays at 6 pm. discussing the economy....

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 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!

This game is located at the DC/Maryland Border in Silver Spring. We'll use the Tennis or Futsal Court, both at 300 Van Buren St NW where there are Night Lights shining on an enclosed arena. This area is enjoyable because it allows for more touches on the ball, with more movement around the field. THIS IS ON A TENNIS COURT. WE DO NOT WEAR CLEATS. WE WEAR FUTSAL SHOES, TENNIS SHOES; ANYTHING WITH NO SPIKES. Pinnies and goals will be provided. Bring a ball if you have one. We usually get 10+ more players not on meetup — we'll add those to whatever we get here and see if we can have a game. More than competitive, we all want to play good futsal and make it fun and entertaining for all. No warm sided matches here — new and advanced players are welcomed. Here, we want to get active and have fun in the evenings after work

Trivia!! Trivia starts promptly at 7, come earlier to get set up 630-645. Clear Sky's Meadery. 15201 Display Ct, Rockville, MD 20850

[Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **“Facing Fascism,”** on the history, hallmarks, and lingering power of a deadly ideology, with Kevin Matthews, professor of history at George Mason University and teacher of courses on early 20th century European history. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/nv-facing-fascism](https://events.ticketleap.com/tickets/profsandpints/nv-facing-fascism) .] Few political movements have aroused as much anger and fear as fascism. But despite its legacy of violence, persecution, and genocide, fascism continues to hold a strange attraction to many. Join historian Kevin Matthews for an in-depth look at an ideology that brought death to millions in Europe and yet continues to deeply influence our politics and culture. Dr. Matthews will start by discussing how the ideology of fascism arose in the aftermath of the First World War and took hold in Europe in the 1920s and 1930s. To give you a better grasp of what exactly fascism is, he’ll discuss its central themes: Anti-democracy. Extreme nationalism and anti-communism. The use, or threat, of violence in politics. Rejection of established values such as scientific objectivity. Denial of equal rights, especially for women. The assertion of power where a power vacuum exists. We’ll examine the rise and fall of two notorious fascist dictators, Adolf Hitler of Germany and Benito Mussolini of Italy. For a time it was believed that fascism died in the ashes of the Second World War, but it clearly didn’t, and we’ll look at where it remains a political force today. Finally, we’ll examine how fascism continues to permeate popular culture in ways that trivialize it, popping up in music from punk to Madonna, with its latent eroticism making it the subject of films such as *The Night Porter.* Having been called “the most self-consciously visual of all political forms,” it enlisted fashion leaders to produce uniforms and continues today to inspire a look known as “Nazi chic.” Dr. Matthews previously has given fantastic Profs and Pints talks on Ireland’s fight for independence and on World War II German submarine attacks off our coasts. He’s sure to leave you with a much better understanding of fascism and a recognition that is has hardly gone away. (Doors: $17, or $15 with a student ID. Listed time is for doors. Talk starts 30 minutes later.) Image: Benito Mussolini and Adolf Hitler during Mussolini's 1940 visit in Munich (photographer unknown / public domain).

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.
