Electronics Projects San Francisco

From San Francisco Kirtan Connection

## 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.

The collective had its debut concert in 2020 in San Francisco, led by core members **Divya Purohit Vyas** and **Jun Ishimuro** (of Qb Moda Jazz). Initially, their work centered around blending South Asian raga-based music with the soulful textures of jazz, R&B, and Black musical traditions. With a flexible and evolving lineup of collaborating artists, Anhad Naad Collective has performed at notable Bay Area venues including **Bird & Beckett**, **Integral Yoga Institute**, the **Golden Gate Park Bandstand**, and events such as **San Francisco’s Summer of Music** hosted by Noise Pop and the **Civic Joy Fund**. In 2023, the group expanded its focus to delve deeper into South Asian spiritual music, with a special emphasis on **Sufi Qawwali** traditions. Anhad Naad treats the spiritual dimension of Sufi poetry and music with deep reverence, often seeking guidance from poets and experts from Pakistan and India. Lead vocalist **Divya Purohit Vyas** has previously been a part of **Bay Dervish** in Alameda, a spiritual music collective associated with *Sufi Way*, led by the late **Kiran Rana** and **Jeanne Rana**. **Anhad Naad Collective Current Members:** * **Divya Purohit Vyas** – Vocals * **Irum Aftab** – Vocals * **Vivek Anand** – Vocals, Harmonium * **Rajnish Kamat** – Vocals * **Rishi D** \- vocal * **Jun Ishimuro** – Flute, Digital Audio Workstation (DAW * **Craig Reiter-** Upright Electric Bass, Cello and Oud * **Abhay Shankar Anand** – Tabla, percussions, Sound Engineering

Fortress Mode: Arduino Motion Gates (CHM)

Tue, Jun 9, 2:00 AM

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!**

DC415

Fri, Jun 12, 2:30 AM

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.

Each will share their literary product with a hacker, who will respond with a device/app/gadget/doohickey inspired by the writing. On the night of the event, audience members will vote for the device that best complements the assigned writer's piece. The winning hacker will receive a prize of dubious value! Expect delicious snackies, and other fun additions: in the past we've included a fun raffle!

Introduction to 3D Printing ($20)

Sun, Jun 7, 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.
