Fortress Mode: Arduino Motion Gates (CHM)

Step into engineer mode and build your own automatic security gate using an Arduino, a motion sensor, and a servo motor! In this hands-on class, you’ll create a mini “fortress gate” that springs open whenever someone approaches. Along the way, you’ll learn: * How motion sensors detect movement * How servo motors create controlled motion * Basic Arduino programming and wiring * How real-world smart security systems work By the end of the class, you’ll have a working motion-activated gate and the skills to customize it with lights, alarms, or secret fortress upgrades. No experience needed — just bring your curiosity and prepare to defend the kingdom. 🏰🤖 **If you have a laptop, please bring it — but come anyway if you don’t!**

Match Point Brewing: One Last Game Night!

EBBG East Bay Board Game Convention and Protospiel

East Bay Board Game Convention returns for its third year! Coming to Oakland July 17-19 to Oakland Marriot City Center. Convention features include: 24 hour access to gaming rooms Library of over 1,000 board games Play-to-win games Flea Market Hot Games Room Dedicated TTRPG space Seminars Protospiel board game playtesting **[Convention Website](https://tabletop.events/conventions/ebbg26)** **Location:** Oakland Marriot Center, 1001 Broadway, Oakland, CA 94607 (2 mintue walk from 12th Street Oakland City Center BART) **Hours:** While the con is open nonstop from Friday morning til Sunday night, the Protospiel board game playtesting area will be officially open during the following hours: Friday: 9am - 10pm Saturday: 9am - 11pm Sunday: 9am - 4pm **Cost:** You must purchase a badge online or in person at the convention to enter the venue. Protospiel playtesting is included as a free event as part of the convention. **Protospiel Participation:** One of the many awesome things to do at the con is playtest board games at the convention's own Protospiel event! Play prototype tabletop games, meet local designers, and learn about the board game industry in a casual friendly environment. The Protospiel is a playtesting area where designers run their prototype tabletop games looking for feedback. Prototypes can be any kind of physical / analog game and in any stage of development. Anyone can join in as a designer and/or player, no experience needed! The Protospiel will be a combination of scheduled playtests, which you can submit throught the convention website in advance and describe it as "playtest", and mostly open unreserved drop in testing. Open tables are not reserved and not exclusive - designers are expected to share table access throughout the con and play each others prototypes. Playtesting is the focus, don't run games that are finished or not open to changes. Staff reserves the right to exclude prototypes that are deemed inappropriate or offensive. We'll be giving out a prize to a random participant every hour til late, so the more you hang out the more you can win! The Protospiel is co-run by Golden Gate Gamemakers. **Protospiel Team:** Velgus, Chaz Glassmaker, Andrew DiLullo.

Spec-Driven Development: The Rise of Builder PMs

**Code got cheap. Clarity hasn't.** AI coding agents can now build almost anything you describe. The old bottle neck of writing code is gone. The new one is saying what to build clearly enough that an agent builds the right thing. This is the shift behind spec-driven development. Instead of prompting an agent and hoping, teams write a spec first: the behavior, the constraints, and what "good" looks like. The agent builds against it. In a world of disposable code, a long-lived spec becomes the artifact that matters most. Product managers have always turned ambiguity into something a team can ship. The PRD is used to align people. The **spec** **aligns** **people** ***and*** **agents**. This is the rise of the **Builder PM**: a product leader whose judgment is precise enough to direct a fleet of agents. Join ProductTank SF and Workato for a panel on spec-driven development and how it works inside real teams. **Key Takeaways** * How **spec-driven development** works * Why the PM role changes when **clarity** is **scarcer** than **code** * **PRD → Spec** and what that means for how you write requirements **The Panelists** * **Chris Butler** is Director of Product Operations on GitHub's Synapse team, where he leads experimentation in AI-powered process automation. He has held product roles at Microsoft, Waze, KAYAK, and Facebook Reality Labs. * **Swetha Sridharan** is a Principal Product Manager at Workato, the automation and integration platform. She builds AI-driven products that orchestrate work across an organization's apps, data, and agents. * **Albert Collell** is a Senior AI Product Leader at Qurrent and teaches product management at Stanford. He uses AI to raise decision quality and turn complexity into clarity at scale. **Special Thanks to our Generous Sponsor** **Workato**: the AI-powered automation and integration platform that lets teams orchestrate work across their apps, data, and agents. Thank you to Workato for hosting us and providing food and drinks. *Attendance will be first-come, first-served. We will close doors once we reach capacity; arrive early to secure a spot.*
