Hardware Engineering

Want to mess with some electronics? Or perhaps contribute to HacDC's main group project? HacDC's latest event brings hardware projects to the community. We will focus primarily on the main project (Space Blimp!) but please feel free to bring some of your own projects to show off and work on!

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 graphene and 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.

📚 Do you love reading, but wish you had a structure and a community to share your insights with? Join our small circle of curious minds (just 4 members per gathering) as we come together for an hour of focused reading—in the calm setting of a library or the cozy atmosphere of a café. Here’s how it works: First part: Quiet reading on your own—bring a book you’re exploring, whether it’s philosophy, history, psychology, literature, or anything meaningful to you. Second part: We regroup and each person shares key takeaways, insights, or questions sparked by their reading. This sparks a structured yet free-flowing conversation around ideas, perspectives, and personal reflections. Why join? Add structure to your reading habit. Discover new books, authors, and ideas through others’ choices. Build real connections by sharing and listening deeply. Socialize around something meaningful instead of small talk.

Title: Quantum Computing for Business (Exploring Opportunities Available Today) Date: June 27 2026 Saturday Noon - 14:00 EDT Summary: Big media reports that current quantum computers are not able to attack business problems at scale. In Ron's experience, this is only about 95% true. He has found that certain types of quantum computers, specifically quantum annealers, are very good at solving constraint based optimization problems at business scale. This presentation will answer the question “What is quantum computing?” by comparing quantum computers to classical computers and describing the various types of quantum qubits. Ron 'll introduce what quantum computers can be used for and what they shouldn't be used for. Next, Ron will look at a number of quantum computing use cases that are currently available to businesses today. Finally, Ron ’ll present conclusions with a brief discussion of future hardware. There will be time for Q & A. Speaker: Ron has been fortunate to have worked in a broad range of technical disciplines during his career. Areas in which he developed expertise and innovative results include, digital hardware design, silicon functional architecture (chips), computer language compiler development, and medical software. Ron has recently immersed himself in quantum computing technologies and has obtained more than a dozen certificates across the quantum spectrum. These technologies include various hardware platforms, numerous quantum programming frameworks and quantum sensors. As a co-founder and CQTO of B2Quantum, Inc, Ron has served as a quantum computing Subject Matter Expert (SME) for a large pharma company. As a SME, he performed quantum computing use case analysis, strategic planning, budget guidance and risk analysis. Outside of the technical arena, Ron is a licensed pilot, certified open water SCUBA diver, bicyclist, wood worker and a once in a while artist.

We play a variety of games with a focus on high interaction Euros. Events will start with quick games while people arrive and eat lunch. We will start longer games between 1:30pm and 2pm. While the official end time is 5pm, people are welcome to continue playing games afterwards. Western Market closes at 7pm on Sundays.

Styled after a 'pitch competition', this event is for entrepreneurs, and the entrepreneurial-curious. Learn about on-going initiatives from local area founders, and there will be ample time for networking. This event will bring together start-up founders and enthusiasts in the DMV area for an exciting opportunity to hear about a fellow founder, and give feedback on their pitch and product, and get to network around founders from the area. ## Details **Location:** 4200 Campbell Avenue Arlington, Virginia 22206 **Our Agenda:** 1\. Basic group introductions 2\. First "Pitch" Presentation \(\~10 minutes\) 3\. Community Q&A 4\. Second "Pitch" Presentation \(\~10 minutes\) 5\. Community Q&A 6\. Third "Pitch" Presentaton \(\~10 minutes\) 7\. Community Q&A 8\. Break out sessions & general networking **Speakers** Chelsea Acheampong (Nova Hospitality): Nova Hospitality is a consumer travel platform connecting conscious travelers directly with verified eco-lodges and community-run properties, redirecting tourism revenue back into local communities through transparent impact verification and direct booking Cameron Peltz (Caldarium): Caldarium is a health admin tech company building software solutions for medical practices, to automate prior authorization paperwork and detect errors in reimbursement claims, to ensure compliance and reduce their rate of rejection by Medicare and insurance payers, getting patients the medicine and surgeries they need more quickly and reliably, and doctor's offices paid for their properly documented procedures correctly the first time and therefore in consistent better financial health. Achinth Murali (Open Judgement Engineering): The Open Judgment Engine (OJE) is an open-source methodology and AI-assisted platform that captures the reasoning behind non-routine engineering decisions — when a judgment applies, when it doesn’t, what the expert does, why it works, and what failure it guards against — as structured, attributed artifacts called Judgment Primitives, embedded directly into the workflow gates where engineers already make those decisions. The goal is to make expert engineering judgment portable, searchable, and permanent — so that when a senior engineer retires, the reasoning behind their decisions doesn’t retire with them.​​​​​​​​​​​​​​​​ Join us for our monthly Pitch Labs meetup!

Extensions allow developers to customize the editor with new features, integrations, and workflow improvements tailored to their needs. In this session, we’ll cover what extensions are and the different types available, including full extensions written in TypeScript or JavaScript, along with lighter-weight extensions such as color themes, language packs, language support, code snippets, and keymaps. We’ll also look at practical reasons a developer might create an extension, from automating repetitive tasks to adding custom tooling. The session includes a hands-on walkthrough of creating a new extension, testing it locally, and understanding the basic project structure. We’ll close with a brief overview of how extensions are packaged and published to the Visual Studio Marketplace and other distribution options. **YouTube Link** TBD
