People doing strange things with electricity!

Along with the usual freewheeling chaos, the quick talks continue this month with Zach Babb, presenting on: "Ripping Digital Identity through Magic: Multi-device Asynchronous Generic Input/output Consensus"

DorkbotPDX is a relaxed, informal show-and-tell for electronic artists, circuit designers, microcontroller programmers, retro computing enthusiasts, video game designers, digital archaeologists, and mod synth gearheads in Portland, Oregon.

Bring your electronic wonders, monsters, and works-in-progress for others to see, or come see what others have been working on! Whether it's code or circuits, electronic creativity of all sorts is welcome here.

Table space with power will be available for project show-and-tell; we'll have a table for drinks and snacks, feel free to contribute to the communal cache/BYOB. The Free cart is back, take or leave some components (don’t leave TOO much, if you have big stuff, maybe check the Discord/mailing list to see if anyone is interested in taking it first!)

People doing strange things with electricity! Along with the usual freewheeling chaos, the quick talks continue this month with Daniel Temkin, author of the new book "Forty-four Esolangs: The Art of Esoteric Code":

"Software art is widely accepted, but can programming languages themselves be art? The new book Forty-Four Esolangs makes this argument, collecting work by a single artist who poses code as prayer to the Greek gods, patterns of empty folders, or typed in tandem by two programmers, the rhythm and synchrony of their typing determining commands. Temkin will share projects from the book in the context of thirty plus years of esolangs, showing the poetic possibilities of this medium.”

Along with the variety of spooky DIY projects that are sure to show up this month, we're continuing our new series of quick talks in the midst of the usual free-flowing chaos. This month's talk is by Jonathan Moore:

"Half again as much means twice the fun!" - Up until the 20 nm process node—the end of the planar-transistor era—the cost per transistor was halving on a regular cadence. Historically, we’ve used that bounty to boost CPU capabilities, but it also meant we could design CPUs that cost half as much. This talk explores that path: what’s happened with cheap CPUs/MCUs and what it might mean for hackers and open hardware.

This talk covers his lessons learned (so far) during development of his Robo-Fetch project, where he is working to create a fully autonomous ball thrower for his dog. He is using this project to teach himself more about the latest digital twin tools for robotics, and to explore the pros and cons of various AI options for physical manipulation with visual feedback. He discusses the kinematic calculations specific to the OpenManipulator design, his efforts so far to build a digital twin of the setup in Blender with plans to transition to Omniverse IsaacSim, and his work-to-date on the AI ball detection.

Join us for our next Portland Area RoboTics Society (PARTS) meeting on February 2nd for a deeper dive into the software that powers longtime robotics enthusiast Dave Shinsel’s latest ROS-based robot, EB-6. Last time, Dave focused on EB-6’s mechanical and electrical design; this meeting will highlight the software stack—including conversational AI (ChatGPT) and advanced vision processing—that brings EB-6 to life. Standing two feet tall, EB-6 uses ChatGPT for conversational AI and sophisticated computer vision to interact with kids (and adults!) in a fun, engaging way

Let us know you're attending on Meetup if you use it! - https://www.meetup.com/ctrl-h/events/294552367/

I'm very happy to announce our next meetup is at the PDX Hackerspace in NW Portland. Its a really great space and perfect for the meetup group. They have a lot of interesting resources and free wifi!

For this meetup we're going to have a little more structure to it. First we're going to have a 'show and tell'. Bring your laptop or borrow someone else's and show everyone what cool new gadget you set up or automation. Or you can just talk about what-ever you want to that you've recently got working in Home Assistant. These will be limited to 5 mins per person

Next, we're going to go through the basics of getting started with Home Assistent. We'll talk about what to install it on, how to get it installed, and then maybe adding some simple device to start. If you have a Raspberry Pi or a device that you want to install Home Assistant on please bring it with you. Also if you have a monitor and keyboard that would be great. If not I believe there will be some monitors available. Those who already have Home Assistant running can help out those who are getting it installed

Last but not least, pizza will be provided. I'm asking that everyone bring their favorite beverage. Ideally beer and cider (I prefer cider!) to go with the pizza

Looking forward to seeing everyone!

Details Hey everybody. Got a bug you just can't land? Is there a recent CVE you've been eyeballing seductively? Just want to brush up on your APPSEC or OPSEC? Do none of the above questions make any sense, but you're interested in computer security?

PDX Exploit Workshop is the longest running security meetup in Portland (10 years!). It's an open, self driven event for people interested in computer security. Whether you're a novice or career professional, all are welcome. It's always a good time to learn about security!

We spend this dedicated time each week researching and exploring topics of software and hardware security as well as working on personal and group projects. Occasionally we have presentations on our findings. Bring a willingness to learn, a curiosity about security, and/or a specific area of interest to share with others.

This group meets in the PDX Hackerspace mainspace which has comfy seating, deluxe wifi (thanks Kyle!), Club Mate soda in the snack shack, and hackable LED displays to play around with.

p.s. This event is open to everyone! No ^H membership is required to attend. All are welcome. That means you!

Happy New Year! Welcome to our second ever OWASP PDX study night. Our January topic will be "Burp Suite Basics" presented by Sophia Anderson. Sophia is a security consultant for NetSPI performing web application penetration tests for Fortune 500 clients to discover vulnerabilities. Sorry no pizza unless you want to bring :).

Study Nights are smaller, bitesize, digestible, skill building mini lectures or workshops for those interested in learning new skills, tools, tricks, or new CTF challenges. It’s also meant for members to practice communication skills and teamwork in a supportive environment.

Study Nights meet the first Tuesday of each month at the ^H hackerspace in North Portland. Doors will be at 7pm, event will start at 7:30pm and wrap up by 8:30. Please bring your computer with Burp Suite installed and preferred note taking mechanisms.

Seating is limited

This class is meant to give each participant a decent introduction to Ableton Live. Class takes place in the crafts room @ Ctrl-H This is a 101 class, so no previous experience is necessary. Intended audience is anyone interested in using their computer for making music. But I'm happy to adjust the class to participants need or take more in depth questions after the introduction during Q&A.

I've been using Ableton Live since version 3 in 2003, and have produced 43 albums of "music"? using it. http://cainmac.bandcamp.com

Bring your own computer with Ableton Live installed, or download the 30-day trial copy at:
https://www.ableton.com/en/trial/

Class is open to anyone and always free to attend.
