Number 1: 532: It's Still Real Fire
Kevin Santo Cappuccio, founder of Architeuthis Flux, joins the show to discuss creating Jumperless, an open-source breadboard that replaces physical jumper wires with software-controlled analog crossbar switches. We explore the need for 445 RGB LEDs on a breadboard, using MicroPython to create scriptable circuits, some of the lessons that can be implemented with the Jumperless, and how it might be used to create new instruments. Kevin also shares the story behind his upcoming Barnacle Board. DISCUSSION RESOURCES & LINKS Jumperless Project & Hardware Resources: Jumperless Docs and Discord Jumperless Shop (Also available via CrowdSupply but any discounts only apply to Kevin's shop) JumperlessV5 · GitHub: Open-source hardware files, schematics, and firmware Barnacle Board - GitHub: The future of jumperless includes a modular breadboard with custom-stamped clips and removable protoboard tops Other Resources and Mentions: Wokwi Simulator: Online browser-based electronic circuit simulator Falstad Circuit Simulator: Kevin's favorite browser-based analog simulator Hackaday Prize 2023: Jumperless took 2nd place in the 2023 contest. Peter Griffin made an Microsoft Excel plugin interface for Jumperless, we discussed it with him in episode 505: Potato in a Number Field. Kevin also talked with Chris Gammell of The Amp Hour with more information about the electrical response, timing, and the crossbars. Giant squid - Wikipedia

Number 2: 530: A Living Highlighter
Marine biologist Dr. Steven Haddock joins the show to share the alien, glowing, and transparent wonders of the deep ocean. We discuss his beautiful new book, The Radiant Sea, and explore the complex engineering and high-sensitivity optics required to capture living deep-sea creatures. Steve walks us through the evolutionary logic of biological light, how vantablack organisms trap photons in the dark, the horizontal sun-compass navigation of jellyfish blooms, and what it's like to play games underwater with giant Pacific octopuses and jumbo squids. Dr. Steven Haddock is a Senior Scientist at the Monterey Bay Aquarium Research Institute (MBARI) and an adjunct professor at UC Santa Cruz.

Number 3: 529: The Narwhal Looked Amazing
Chris Svec returns to the show to discuss the messy, non-linear realities of engineering management and onboarding new college graduates. We explore why companies should bother hiring fresh grads in the first place, how to prevent junior developers from going dark when they get stuck, and why admitting ignorance publicly is an absolute workplace superpower. Along the way, we dive into managing genius firmware engineering hires, battling technical debt and software entropy, and why your development team shouldn't communicate solely through pull request comments. Chris Svec is the Director of Embedded Software Engineering at Insulet. If you're looking for an experienced leadership or management thought partner to help scale your development team, Chris Svec offers private coaching and consulting. You can reach him directly at the email given in the show (or hit the contact link and we'll forward your message along).

Number 4: 534: I Think We'll Add a Head
Aaed Musa joins us to talk about building robot dogs, custom actuators, and his YouTube channel. He shares how he moved from 3D-printing servo robots in his parents' garage to designing capstan drives, and how he uses reinforcement learning to train quadrupedal walking gaits. We also talk about his senior design project (CARA 2.0), his Spider-Man web-shooter build, lessons in storytelling and video editing, and why he's starting a company to bring friendly, expressive quadrupeds into the home. Aaed Musa is a mechanical engineering graduate from Purdue University, a hardware creator on YouTube, and co-founder of the robotics startup Mecha. DISCUSSION RESOURCES & LINKS AAED'S CHANNELS & PROJECTS: Aaed Musa on YouTube: Project videos covering quadrupedal robot dogs, Spider-Man web shooters, and custom actuators. Oh, and planetary gears.
