Fortress Mode: Arduino Motion Gates (CHM)
Tue, May 26, 2:00 AMStep 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!**

East Bay Chronic Pain & Illness Peer Support Group Meetup
Wed, Jun 3, 12:30 AM**About us:** The Bay Area Chronic Pain & Illness Peer Support Group is a friendly, unstructured, in-person peer support group for anybody 18+ who lives with chronic pain, illness(es), invisible disabilities, and any type of mental health experiences. The group is a casual safe space to hang out, talk about our lives, share coping strategies, form friendships, create community, and get support. **Location:** 2727 California Street, Berkeley, CA 94703 Look for a corner gallery in a residential neighborhood! **Accessibility Info:** * The meeting space is in a wheelchair accessible gallery. * There are bathrooms accessible via ramp within the gallery. * The lighting is relatively gentle, though of course feel free to bring hats, sunglasses to adjust! * Seating provided by the gallery are wooden, foldout chairs. If a metal foldout chair would be preferable, let me know, and I'll try to procure some! * Feel free to bring heating pads, yoga mats, cooling pads, to make yourself as comfortable as possible! \*\*\*Please refrain from wearing anything scented, including lotion, dry-cleaned clothes, etc. This is to ensure that the group is safe for people with chemical sensitivities.\*\*\* **Scheduling Info: While this group runs every other week, there are a few dates when the space will not be available. Those dates are: 4/7, 5/5, 6/2, and 11/3! To play it safe, check on the meetup page to be sure that we are meeting!** **COVID Safety:** * We are asking folks to mask!

Introduction to 3D Printing ($20)
Sun, May 24, 7:00 PM**$5 is charged to hold a spot for this class. You can pay the remaining $15 in person with PayPal, credit cards, or cash.** *All instructors at Noisebridge are volunteers. 100% of your donation is tax-deductible and supports Noisebridge directly.* This class is meant to get you from 0 to your first 3D print. In this class the full workflow from design to printed object will be demonstrated. Topics covered: * Where and how to design or download objects (TinkerCAD/Printables/MakerWorld) * Filament types, when to use which, and how to handle them * How to convert your design into a file that's able to be printed * How to print with supports, make objects stronger, and adjust quality * How to load and unload filament and general print prep * How to send your design to the printer and watch it go! If you are interested you can use one of our 3D printers after the class to apply what you have learned. It's recommended to bring a laptop if you plan to do your own prints. There are no guarantees that a printer will be available. They are first-come-first-serve and are used for many different Noisebridge projects.

(SF) Discuss life with chronic pain, illness, invisible disabilities, & anxiety
Thu, May 28, 1:00 AM**About us:** The Bay Area Chronic Pain & Illness Peer Support Group is a friendly, unstructured, in-person peer support group for anybody 18+ who lives with chronic pain, illness(es), invisible disabilities, or any type of mental health experiences. The group is a casual safe space to hang out, talk about our lives, share coping strategies, form friendships, create community, and get support. The group is part of [Better Because Collective](https://betterbecausecollective.org/), a mental health nonprofit that supports people as they navigate difficult life experiences. We also offer an online platform where people can [share their stories](https://betterbecausecollective.org/stories/) of growth and healing. Our goal is simple: to offer connection, kindness, and hope. **Location:** 54 Iris Avenue, San Francisco, California 94118 Look for a blue residential building with silver banding and palm trees in the front with an open garage door. In the garage, a bunch of folding chairs will be set up in a circle with people sitting together and socializing. **Accessibility Info:** * The meeting space is in a private residential garage that is wheelchair accessible. * There are wheelchair accessible bathrooms a block away at Starbucks and Peet's. * The garage is scent-free. * The garage is not low-light, so bring sunglasses if you need them. * There is street parking on the same block and a free-of-charge parking lot a block away. * The meeting space is nestled between the #1 MUNI and the 38 MUNI. \*\*\*Please refrain from wearing anything scented, including lotion, dry-cleaned clothes, etc. This is to ensure that the group is safe for people with chemical sensitivities.\*\*\* **COVID Safety:** * The garage door is left open for ventilation. * Masking is optional at this time. * Wear warm clothes and bring a throw blanket since the garage door remains open for ventilation/COVID safety. If you have any questions about the event, feel free to email Rebecca at [rebecca@betterbecausecollective.org](mailto:info@betterbecausecollective.org)

Session 3: Breadboarding the Op-Amp
Sat, Jun 6, 8:00 PM## Session 3: Breadboarding the Op-Amp If the transistor is the building block of analog electronics, the **op-amp** is the Swiss Army knife. Op-amps show up everywhere in guitar pedals — as clean boosts, buffers, tone stacks, and the gain stages at the heart of overdrive circuits. The Tube Screamer, the RAT, the LM308-based fuzz variants — all built around op-amps. In this session we'll get hands-on with the op-amp on a breadboard and learn how to put it to work. We'll cover: * **What an op-amp is** — and how it differs from a transistor amplifier * **Biasing** — setting up the op-amp to work with a single-supply voltage, like a 9V battery * **Setting the gain** — using feedback resistors to dial in exactly how much amplification you want * **Building a boost or buffer circuit** — and hearing the difference it makes No prior experience with op-amps needed. If you've been following the series, you already have all the foundation you need — but newcomers are welcome too. Already working on a pedal project? Bring it! Whether you have questions, need a second pair of eyes, or just want to solder alongside others, you're welcome to work on your own build.
