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.
