I 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).
395: I Can No Longer Play Ping Pong
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!). XKCD comic referenced: xkcd.com/1319 Fitbit’s Tower of Terror Bug
394: Being Four-Year-Olds
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

391: The Lesser of Two Weevils
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.
