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.

**LOCATION CHANGE as of APRIL 1, 2026:** **Body Grace has moved to 133 Maple Avenue East, 3rd Floor, above the Bear Branch Tavern.** Whether you're new to Insight meditation or an advanced practitioner looking for like-minded people to sit with, you're welcome to join us at our Sunday morning drop-in group, sponsored by the Insight Meditation Community of Washington. Insight meditation cultivates our natural wisdom and compassion. Meditation practice develops concentration, which allows us to calm and steady the mind. This class includes a 30-minute lightly-guided meditation, followed by a short talk and time for questions and discussion. The size of the group usually runs somewhere between 25-40 people in-person and between 12-25 online. Chairs are provided, or you may bring a sitting cushion or bench. You may also use the blankets and bolsters offered by the yoga studio. **We offer both in-person and online attendance.** To learn more about our topics and teachers, view our videos or **get the Zoom link**, visit our [class page](https://imcw.org/event/?eventId=735&utm_source=MeetUp&utm_medium=referral&utm_campaign=vienna-drop-in).

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...
