***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

We'll come together to talk about writing custom apps. Macoy Madson will show how he applied Handmade principles to creating a custom CAD application for a manufacturing company. He will go over the various features and his criteria for what he picked to build vs buy, as well as lessons learned from the shortcomings of his choices. If we have time, we'll also look at compiling native code to WebAssembly. **Agenda:** \- 2pm \- 3pm: Custom app presentation and WebAssembly \- 3pm \- 4pm: Open\-ended discussions\, presentations\, etc\. \- 4pm \- whenever: We'll go get food nearby\! **What we do** Presentations on lower-level, foundational programming topics, ethical software, knowledge sharing, mentoring, and discussion. **Who we are:** We are all about handmade software. Rather than focus on frameworks, heavy abstractions, and buzzwords - we typically create projects or research topics that build an understanding of foundational computing concepts, essential data structures, and hardware/software interaction. **What to bring?** Bring a laptop, project, or just a curious mind. If you're not sure you're ready to contribute, don't worry: we're all here to share our passions and hone our craft. **If you arrive late:** Please enter the room quietly as to not disrupt anyone that is presenting. You can take any empty seat.

This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD
