Building a Scanning Tunneling Microscope - Systems Testing
***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. 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.

Meetup #16: API Design & Single-Header Libraries
This month, we'll have a recorded talk, followed by discussion, on API design and single-header libraries.

**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.

Be aware that this time of year where segments along the river can be muddy and there are some rocky areas we must maneuver around.
Bring a mascot! The park is dog-friendly, but must be on a leash.

Code Anywhere by Talking to your Phone
Drake Lundstrom is presenting:
Code Anywhere by Talking to your Phone
Abstract:
Have you heard the trend of people deploying code anywhere from checkout lines to doctors' offices? In this talk, you will learn how to talk to your phone and have an app on Azure to show your friend 5 minutes later. The basic DevOps tools you already know, plus a little bit of AI magic, are all you need!
If you want to follow along, the demo will be in Azure with GitHub Actions and GitHub Copilot, and you can have it set up on your phone by the end of the session. Just come in with an Azure account and a GitHub repo.
Join us for pizza, drinks, and networking @ Improving's office. Doors open at 5:45.
