Digital Signal Processing

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.

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.

This is a casual gathering, and we know that people might only be able to stay a little while -- drop in, and stay, as long as you are having fun, and as your day allows. **Note: about RSVP's, please respect the RSVP process. If you RSVP YES, you are commited and we are all looking to seeing you. If your plans change however, that's OK, but please be courteous and change your RSVP to NO. We are reaching the headcount limit regularly now and it is rude to take a spot and not relinquish it if your plans change... Respect others; don't be rude. Thank you for your cooperation**. All skill levels are welcome -- this is not a competition. This Group and all its Events are intended to be in equal parts, Drawing/Art AND Socializing. As such, conversation is expected and encouraged. ***However, in all cases, please refrain from discussion of Political topics.*** Our goal is enjoyment, in the form of drawing together while socializing, and political conversation is too polarizing for that to happen. We are looking forward to seeing you there! **Note (in parting): Be aware, and keep in mind that our group, meeting as it does at Starbucks, depends on this business's generosity for the space it allows us. As such, please make a point of purchasing something from the business to express our appreciation as a group using their facility. If you are experiencing hardship and can't afford a modest purchase, get my attention discreetly, and arrangements will be made with no judgment whatsoever. Thank you for your understanding...

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
