CHM - Soldering practice and circuit testing with an oscilloscope

Build a function generator and practice soldering at the same time. With a soldering kit that we provide, you will assemble a circuit that generates sine-waves, triangle-waves, and square-waves. Then you will test the circuit with an oscilloscope. This kit is a little above the beginner level, so we plan to extend this project into a second week. Once your function generator is working, you can pair up with another workshop participant and observe two function generators sending waves to an oscilloscope in "X-Y" mode. This pattern is called a Lissajoues Figure.

This group was created to bring together people who share a passion for cybersecurity and a curiosity about how things work. The goal is simple — to connect with other humans who enjoy meaningful, inspiring, and sometimes unexpected security conversations more than just once a year. Many of us have returned from security conferences feeling both inspired and overwhelmed — full of new ideas and projects to explore, only to have life pull us in other directions. Maybe a demanding client, a new sprint, or even a new baby shifted priorities away from that funny blinky badge project sitting on a shelf. If that sounds familiar, you’re not alone. This meetup offers a space for like-minded individuals to gather once a month, share what’s captured their attention, discuss recent exploits or discoveries, and showcase projects born from curiosity or necessity. Whether it’s a half-finished experiment, a new idea sparked by a problem, or something ready for collaboration, this is a place to share and grow together. Most of all, this group encourages rediscovering that spark of curiosity — dusting off those badges, boards, and brainstorms — and diving once again into the spirit of exploration that brought us all here.

Agrivoltaics in California: Growing Food & Generating Clean Energy

California is working to meet ambitious clean energy goals while protecting productive farmland and managing increasingly scarce water resources. Could agrivoltaics—combining solar energy generation with agriculture—help address all three? Join us for a conversation with **Michelle Cox, Program Manager at HARVEST California**, exploring the rapidly evolving agrivoltaics landscape in California. Moderated by **Emmet Murphy**, the discussion will look at how dual-use solar can support farming, water resilience, and California’s clean energy transition. We’ll explore: * What current research tells us about impacts on crops, water use, biodiversity, and farm resilience. * Lessons from California research and commercial projects, as well as experience elsewhere in the U.S. and internationally. * How agrivoltaics could help California navigate the intersection of **food, energy, and water**. * Policy, economic, and practical barriers to adoption—and what it will take to responsibly scale. Whether you work in agriculture, energy, climate technology, research, policy, or investing—or are simply curious about innovative climate solutions—join us to explore the potential of producing renewable energy while keeping California farms productive and resilient. **Agenda** * 5:00 - 5:30 Check-in and networking * 5:30 - 6:30 Presentation and Q/A * 6:30 - 7:00 Open networking ​**About 9Zero:** We’re a members-only community of founders, investors, scientists, and innovators accelerating climate solutions through meaningful relationships.

Circuit Hacking Monday – Open Electronics Workshop

Need some motivation to finish that electronics project? Join us for an open workshop where everyone brings something they're working on. We'll have soldering stations, test equipment, and a room full of people interested in electronics, programming, robotics, and embedded systems. Whether you're debugging a circuit, writing code, or designing your next gadget, you're welcome here. No lectures. No pressure. Just making things together.

Open House / Open Build / Open Repair Projects Workshop

Our monthly Circuit Launch Oakland "Open House" evening for everyone, fun for the whole family! Join us every third Friday evening of the month: **○ Robot, AI and Electronics Projects:** Start a project, continue a project or discover one here: we provide the space, tools and peer learning – you bring your project and enthusiasm! **○ Repair Projects:** Fixit Clinic's monthly residency at Circuit Launch: bring your repair projects – electronic gadgets, appliances, computers, toys, etc.– for consultation, assessment, disassembly, and possible repair. We’ll provide workspace, specialty tools, and guidance to help you disassemble and troubleshoot your item. First-time repairers and “Fixing Families” are heartily invited. Learn more at [https://www.fixitclinic.org/](https://www.fixitclinic.org/) **○ Tech Topic Discussions and Practice:** join the AI thought leadership practise group for lively conversation: Come share your knowledge -- or your lack thereof: all experience levels welcome. It's definitely worth a visit if you've never been here: tour Circuit Launch and see all the exciting companies and projects in progress. – U18s heartily welcome with a participating adult. – Equipment use outside of the soldering and debugging gear requires certification.
