Building & Renovation

This is an opportunity for volunteers to support a professional mechanic as he guides customers working on their own bikes. If you know how to do some basic repairs, that's a plus, but even if you don't, you can greet customers and manage who gets helped next. Feel free to attend for only a portion of the time if you can't be there the whole three hours. Please note that this event is not usually an opportunity to learn about bicycle repair, since the mechanic tends to be very busy helping customers, especially during the warmer months. But it's a great way to contribute to Velocity, since almost all the funding for the volunteer program comes from the work done at the shops.

Everyone is welcome to attend our weekly happy hour, at Tony & Joe's Waterfront Bar in Georgetown (3000 K. St, NW). The event goes from 7:15 to around 10:00 PM. Feel free to show up at any time. French speakers of all levels- from beginners to expats- are invited. We hope to see you there!

Everyone’s prompting. Few people are judging. This talk shows how a playwright uses multiple LLMs and vibe coding to build a custom evaluation loop: a digital dramaturg that checks scenes against an outline like a living spec. If you design, build, or eval AI systems, you’ll leave with a new mental model for using LLMs as QA, not just content engines. **Featured speaker:** * [Soo-Jin Lee](https://www.linkedin.com/in/soo-jinlee/)\, Gen AI Conversation Designer \| Prompt Engineer \| LLM\, NLU\, NLP \| Human in the Loop \| Former Teacher \| Playwright **Location:** AWS Skills Center, 1550-G Crystal Dr, Arlington, VA 22202 **Drinks and Networking After:** --> Alamo Drafthouse, 1660 Crystal Dr, Arlington, VA 22202 (2nd Floor) **Description:** Join us at AI Innovators Network for our upcoming meetup in the Mosaic, which is dedicated to exploring the latest trends in Artificial Intelligence.

***In Person Location:*** Rockville Library, second floor meeting room (Collaboration Room 3). 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. 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
