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.

Thirsty Thursday is about trying a solid Medium Level ("B" group) ride in an encouraging, structured environment. We welcome strong Beginner Level riders that are willing to push themselves to become better cyclists. This is a NO DROP ride so you will not be left behind but you are expected to really try to keep pace. The lead will go no more than 16mph and other organizers/helpers will attempt to "fill the gaps" as we ride. This is a mostly flat ride from Jones Point to Fort Hunt. Of course the "price of admission" for this ride is a hill that presents itself as soon as we enter the neighborhood across the GW Parkway... we have named it "The PUNISHER". If you successfully climb that hill, you are officially a CBG "B" group rider. Once we get to Fort Hunt we will do laps (or you can rest) for a bit before heading back the way we came. If you normally ride faster than 15mph you are welcome to practice your "keeping pace" skills. If you've done this ride at least once before and have the route loaded on a Bike navigation computer (Garmin, Wahoo, Etc...) or the RidewithGPS app there is also an "A" group version that you can sign up for (aka Very Thirsty Thursday) that rides independently and faster. **+++++++++++++++++++++** **The Meeting Spot:** **+++++++++++++++++++++** Jones Point Park Jones Point Dr. Alexandria , VA 22314 GPS: [https://goo.gl/maps/kZ3zjBHHcQF2](https://goo.gl/maps/kZ3zjBHHcQF2) Gather under the bridge by the restrooms. **+++++++++++++++++++++** **The Ride After The Ride:** ***(This is the "Thirsty" part of the ride)*** **+++++++++++++++++++++** Southside 815 815 South Washington St. Alexandria, VA 22314 703.836.6222 [http://www.southside815.com/](http://www.southside815.com/) **+++++++++++++++++++++** **Ride Level Chart** **+++++++++++++++++++++** NoVA CBG tries to accommodate all levels of cyclists by offering different types/levels of rides. We just ask that you come to the ride that suits your current riding ability the best. * Introductory Level: If you haven't ridden a bike in a number of years (or are uncertain of your abilities on a bicycle). * Beginner Level: You can ride for 10+ miles at a pace of 10+ to 12+ mph with potentially minor hills involved. * Medium Level: You can ride for 20+ miles at a pace of 13+ to 15+ mph with potentially moderate hills involved. * Advanced Level: You can ride for 20++ miles at a pace of 15+ mph with potentially major hills involved. Both Medium and Advanced Levels might require handling various challenges such as reading cue sheets, using a Garmin or navigation app, night riding, out of town travel, or any other odd cycling situations. **+++++++++++++++++++++** **The Fine Print:** **+++++++++++++++++++++** An RSVP of 'YES' is your digital signature and means you have read and understood MEETUP.com's: * "Terms of Service : Section 6.

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.

Let's get together to play some competitive quads and doubles volleyball. **COST**: FREE **Court Type**: Outdoor grass **Minimum Skill Requirements**: Intermediate (click [here](https://docs.google.com/document/d/1PojSi4qdlRsv1msCHhvpQ43iDc4FfzQwpWCc3kafVMY/mobilebasic) for details) Attention: 1. This event is **NOT on a first come-first serve** basis and players with higher skill level and players who can bring a net/ball will get priority over others on the wait list. 2. Since skill levels are **self-reported**, some new attendees may not meet the expected level. For doubles, we encourage you to choose a partner you can enjoy the game with, and since this a competitive event, it is okay if you make a strong team and win all the games. 3. Each person must help set up and take down one net, leaving some nets unset for latecomers. 4. Please answer all questions, so it's helpful for us to organize the event. **Smiley Social documents:** 1.

Meet in the parking lot of the Handy Bikes Service Center. At the start of each ride, we'll go over introductions to have a sense of participants' cycling experience. Over the course of our rides, we'll address the following: group riding dynamics; safety (ABC check & trail hazards); gear shifting; hill climbing; audible and hand communication within the group, with other trail users, and automobile drivers; what to bring on each ride; etc... Bring your questions, water & a snack. When it starts getting dark earlier, we'll need lights as well. Helmets a MUST. If you can, and especially if you've had issues with your bike, come a bit early to have it looked at ahead of the ride. PS - all levels are welcome to join, however, be mindful that if you are an experienced rider, please be prepared to ride at the pace of the newest rider in the group. Each week, depending on who's in attendance, and participants' riding ability/comfort level, we may do skills practice as a group in the parking lot or at the west end of Wheeler Ave. Once everyone is comfortable, we'll go for a ride on local trails and neighborhood streets and finish back at the shop. Happy Pedaling !! \~Maya
