Stay ConnectedI am Elecia White alongside Christopher White. We’re here to chat about the interests, careers, and lives of engineers, artists, educators and makers. Our diverse guest list includes names you may have heard and engineers working quietly in the trenches. Either way, they are knowledgeable, enthusiastic, and inspiring.
We’d love to share our enthusiasm for science, technology, engineering, art, and math (STEAM).

Tyler Hoffman joined us to talk about developing developer tools and how to drag your organization out of the stone age.
You can use GDB and Python together? Yes, yes you can. And it will change your debugging habits. (You can find many other great posts from Memfault's Interrupt blog including one about Unit Testing Basics.)
Tyler is a co-founder at Memfault (memfault.com), a company that works on IoT dashboards and embedded tools. On Twitter, Tyler is @ty_hoff and Memfault is @Memfault.
Control-R is a history search in shell commands (magical!). The fuzzy search tool discussed is FZF (probably even more magical!).

Professor HyunJoo Oh of GeorgiaTech spoke to us about paper machines, paper mechanical movements, paper sensors, paper tiny Jansen Strandbeests, and paper art.
HyunJoo is a professor at GeorgiaTech. She is the director of the CoDe Craft group. Some of the projects we spoke about can be found on the CoDe Craft Projects page.
PaperMech.net has demonstrations of different mechanical movements as well as FoldMecha which shows you what cardboard you need to cut out to make your own mechanical movement, including making a cardboard walker using Jansen mechanism (Theo Jansen (wikipedia) made the Strandbeest). HyunJoo recommends two books for exploring further:
The 507 Mechanical Movements book as a way to explore more mechanical movements
Paper Automata: Four Working Models to Cut Out and Glue Together by Rob Ives
With Unblackboxing Computers, HyunJoo is exploring sensors that can be made with copper tape on paper. The introduction video: https://vimeo.com/637626404/f670dff03e
Professor Carlotta Berry from Rose-Hulman Institute of Technology joined us to talk about robotics, PID tuning, engineering education, ethics, her book, and standing up in front of a classroom.
Carlotta's book is Mobile Robotics for Multidisciplinary Study (Synthesis Lectures on Control and Mechatronics).
She has a page at Rose-Hulman as well as a personal blog and a consulting site (NoireSTEMinist.com). She is an advocate for BlackInRobotics.org.
On Twitter, Carlotta Berry has a personal account (@DrCarlottaBerry) and a professional account (@NoireSTEMinist). She is also the @BlackInRobotics coordinator.
An explanation of Zeigler-Nichols PID tuning with pros and cons.
Colin O'Flynn (@colinoflynn) spoke with us about security research, power analysis, and hotdogs.
Colin's company is NewAE and you can see his Introduction to Side-Channel Power Analysis video as an intro to his training course. Or you can buy your own ChipWhisperer and go through his extensive tutorials on the wiki pages.
Some FPGA resource mentioned:
MyHdl.org (Python!)
Debra Ansell joined us to talk about making light up accessories, patenting ideas, and sharing projects.
Debra's project website is geekmomprojects.com, she's @geekmomprojects on Twitter and Instagram. Her github repo uses the same ID: github.com/geekmomprojects/.
We talked about using coin cell batteries as switches. Many other accessories do this but one of our favorites was the Tiny Edge Lit Sphere.
Debra's company is brightwearables.com. She holds patents US10813428B1 and US11092329B2.
Chris and Elecia chat about their current projects and ideas.
Elecia is teaching Making Embedded Systems at Classpert. The course is based on her book with lectures to extend the information, quizzes, homework, mentors, synchronous classes, and a final project. Starting Nov 13th, the first cohort is full but you can join the waiting list. The second cohort starts in February.
Elecia is also giving a keynote at Hackaday's Remoticon! It is Friday Nov 19 and Saturday Nov 20. Tickets are free, get yours now! Jeremy Fielding will be the keynote speaker on Saturday. Hopefully, she'll have figured out how to use spaghetti sharing as a metaphor for stacks and heaps by then.
The EP for Chris' 12AX7 album is coming out soon: #ihateeverything. The cover art is generated with a GAN from this Reddit post.
Terrible Halloween jokes are collected on Twitter under the tag #EmboodedSystems.

Tyler Hoffman joined us to discuss the issues associated with embedded devices at consumer scale. We talked about firmware update, device management, and remote diagnostics for millions of devices.
Tyler is a co-founder at Memfault (memfault.com), a company that works on IoT dashboards and embedded tools. (We will invite Tyler back to talk about embedded tools but someone was preparing a lecture on firmware update and device management.)
Tyler writes for Memfault's Interrupt blog which has excellent advice including the mentioned article about Defensive Programming. You can also find him and Memfault on Twitter: @ty_hoff, @Memfault.
Elecia is teaching Making Embedded Systems at ClasspertX, a high-quality MOOC with video lectures, quizzes, exercises, synchronous discussions classes, and a portfolio-worthy final project. The alpha cohort starts in early November and the course will run again in Q1 2022.
Alpenglow's Carrie Sundra spoke with us about frivolous circuits, solder live streaming, and yarn.
Alpenglow Industries sells frivolous circuits, some pre-built (like FUnicorn) and some are buildables such as the cute but evil heart soldering kits called PS-I Hate You.
Carrie's YouTube channel is alpenglowindustries where she livecasts Wednesday afternoon Pacific Time. You can still watch the Blob Solder sesh with Debra of GeekMomProjects. Please send pictures of your blobs. One of the recent videos talked about Teenage Engineering Pocket Operators. Our favorite is Arcade.
Alpenglow Yarn sells electronic-based tools for dyers and yarn creators.

Alpenglow also has a Tindie store: alpenglow/
Janelle Shane (@JanelleCShane) shared truly weird responses from AIs. Her website is AIWeirdness.com where you can find machine-learning-generated ideas for paint colors, ice cream, and cocktails (and many other things). We never said they were good ideas.
Janelle's FAQ will help you get started trying out RNNs yourself. We recommend the Embedded show titles.
We talked about BigGAN which generates pictures based on input images.

Janelle's book is You Look Like a Thing and I Love You. Sign up for her newsletter to get the PG-13 versions of her hilarious AI outputs.
Alan Cohen joined us to talk about brain waves, medical product development, open source, and helpful engineering.
Alan has been working on VolksEEG (volkseeg.org, github.com/VolksEEG/VolksEEG). This is an EEG (wiki Electroencephalography) which detects brain waves. It uses the TI ADS1299 EEG monitoring chip and the Adafruit Feather nRF52840 Sense.
Alan wrote Prototype to Product: A Practical Guide for Getting to Market, published by O'Reilly. He talked about it on a previous episode: 269: Ultra-Precise Death Ray You can find him on twitter as @proto2product and on LinkedIn.
Helpful Engineering (helpfulengineering.org) aims to deliver more open source solutions to society's systemic challenges.
