    Chat, J'ai Peté!

    Chris and Elecia talk about Murderbot,  LLMs (AI), bikes, control algorithms, and fancy math.  The website with the ecology jobs is wildlabs.net from 501: inside the Armpit of Giraffe with Meredith Palmer and Akiba..  The algorithm Elecia mentioned was from Patent US7370713B1. The Control Bootcamp YouTube series is a great introduction to control systems beyond PIDs There is also a book from the same folks (with matlab and some python code): Data-Driven Science and Engineering: Machine Learning, Dynamical Systems, and Control. Finding bad AI interactions is too easy. Copilot PR mess that was discussed. Lawyers letting ChatGPT hallucinate precedents. Fake (hallucinated) citations in a high-profile report on children’s health. Transcript Nordic Semiconductor has been the driving force for Bluetooth Low Energy MCUs and wireless SoCs since the early 2010s, and they offer solutions for low-power Wi-Fi and global Cellular IoT as well. If you plan on developing robust and battery-operated applications, check out their hardware, software, tools, and services. On academy.nordicsemi.com, you’ll find Bluetooth, Wi-Fi, and cellular IoT courses, and the Nordic DevZone community covers technical questions:  devzone.nordicsemi.com.

    Inside the Armpit of a Giraffe

    We spoke with ecologist Dr. Meredith Palmer and embedded engineer Akiba about lions, terror, and technology.  Akiba works for FreakLabs.org on global conservation projects. We talked about their Boombox which Meredith uses to create experiments to map the landscape of fear in predator/prey relationships. While this may look like pranking animals with jump scares, well, there is real science being done.  What would it look like to be smooched by a lioness? (Video) Bird hears lion, decides to go over there (Video) Checking the reflexes of some zebras and other critters (Video) Hyena eating camara (Video) These are lots of fun to watch and you can find the freshest ones and help out science by categorizing some at Snapshot Safari. Or skip to using the data on Lila.science (Snapshot Safari 2024 data). Check out Meredith’s website for more github and Data Dryad links to data and science.  If you want to get involved, Wildlabs.net has discussions around conservation technology. There is also a Slack group by Sara Beery focusing on AI for conservation. Elecia mentioned David Quammen, an author who writes a lot about biology and ecology. And now, a guy gives birth to a botfly. Transcript If you’re interested in the intersection of neuroscience and engineering, you might want to check out what Mouser Electronics is doing with Brain-Computer Interfaces. It’s all about how you can control machines with your mind, and it’s one of the coolest areas of innovation right now. Mouser’s Empowering Innovation Together site has great content on BCIs, from videos to in-depth articles and podcasts that break down the tech. If this piques your curiosity, head over to Mouser.com/empowering-innovation and explore what’s happening with BCI and other exciting developments in the world of design and engineering.

    To Consume Stickers

    At the end of this week’s show, Elecia reads a Winnie the Pooh poem as Cookie Monster death metal. Before that, Chris and Elecia chat about mental health, journaling, personal projects, and listener questions.  Please sign up for the Nordic Giveaway!  You can also sign up for the Embedded newsletter. Maybe now with job postings? Elecia’s journaling notebook is this one on JetPens (which is where she gets her nice pens and some of her stickers and washi tape).  From discussing some listener messages, we mentioned: Matt Keeter’s talk on debuggability in production where you don’t have access to the system that is faulting (video and slides) Letter boards (in the Adirondacks), see those in action here Wokwi simulator is a great place to get more embedded experience without buying all the kits. Christopher has said that there will not, definitely not, under any circumstances, be a whole death metal album of Winnie the Pooh poems. Elecia is practicing anyway.  Transcript Nordic Semiconductor has been the driving force for Bluetooth Low Energy MCUs and wireless SoCs since the early 2010s, and they offer solutions for low-power Wi-Fi and global Cellular IoT as well.

    Everyone Likes Tiny

    OpenMV has a new Kickstarter so CEO Kwabena Agyeman chatted with us about more powerful (and smaller!) programmable cameras.  See OpenMV’s site for their existing cameras. See their (already funded!) kickstarter page for the super powerful N6 and the ridiculously small AE3. Note that OpenMV still is committed to open source. See their github if you want to know more. Edge AI is the idea of putting intelligence in the devices (instead of in the cloud). There is an advocacy and education foundation called Edge AI Foundation. This organization was formerly the TinyML Foundation. Edge Impulse and Roboflow are companies that aid in creating and training AI models that can be put on devices.  ARM talks about their Ethos-U55 NPU (and how to write software for it). Transcript
