What we’re about

This group is for all people interested in DIY projects, prototypes, electronics, hardware/software, and a community of technologists.
Find out more about us at: http://www.mocomakers.com

We meet in person once a week - every Thursday night - so look out for those events in particular. The topics rotate.

  • Building a Scanning Tunneling Microscope - Signal Analysis and Next Steps

    Building a Scanning Tunneling Microscope - Signal Analysis and Next Steps

    Rockville Memorial Library, Rockville Town Square Plaza, 21 Maryland Ave, Rockville, MD, US

    In Person Location: Rockville Library, second floor meeting room (Meeting Room 3).

    We are experimenting with a new virtual join link - https://meet.jit.si/mocomakers
    If you can make it in person, that's always recommended!

    Group member Oleksii designed two new pre-amps for us, and we tested both designs. The noise issue looks resolved with some caveats; when you hold the board with your fingers the noise is reduced. If we can ground and shield it, it should be good to go. Join us for this session where we continue progress and get deeper into signals analysis and design improvements.

    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, to launching products, winning grants, 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/ - 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

    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.

    In Person Location: Rockville Library, second floor meeting room (Meeting Room 3).
