Kjetil Meisal, CEO and co-founder of Norwegian semiconductor startup ONiO, joins Chris to discuss the development of ONiO.zero, a revolutionary batteryless microcontroller powered entirely by ambient energy harvesting.

Dave and Chris catch up on the shift toward practical hands-on engineering education at universities, open-source robotics, calculator forensics, mentoring young engineers, AI-assisted PCB layout tools, reverse-engineering scope RF sections, and why Chris wants to be “the Walmart greeter of electronics”

Andy Kong is creating Chargerless, a pre-seed wearable biometric device that runs on 1 minute of sunshine per day. He joins Chris to talk about low power design, unconventional power schemes, the weird signals of the human body, and more.

Kevin Cloutier is the North American Lead for Physical AI at a global engineering consulting firm and a computer engineer who is passionate about taking complex computations to the edge. He joins Chris to discuss the transition from legacy, statically programmed factory robotics to modern, imitation-learning-based “Physical AI,” building and calibrating the affordable $200 3D-printed SO101 robot arm using the LeRobot open-source framework or Intel’s Physical AI Studio, and orchestrating complex robotic systems entirely on local edge hardware.

Robert Fennis joins Chris to demystify the black magic of RF and talk about his open-source, Python-based 3D electromagnetic solver, EMerge. They discuss why simulation is like building a pyramid of knowledge, how silk screen can completely de-tune a patch antenna, and Robert’s quest to build the “IKEA of FEM solvers” so hardware developers everywhere can simulate their designs without relying on insanely expensive proprietary software.

Dave and Chris celebrate 16 years of the show (1st episode was August 10th, 2010) by launching a brand-new static website featuring searchable transcripts and a “pissed-old amber” SVG scope with a working focus knob–and links to merch!. They also discuss Dave’s new employee, 10 cent RISC-V debuggers, and why naming your startup after an un-Googleable Australian cryptid is a bad move

Dr Greg Charvat, CTO and co-founder of Teradar, joins Chris for a 5th appearance on The Amp Hour to talk about how terahertz frequency radar will revolutionize the automotive space and far outstrips the capabilities of LIDAR and Blobbology

Alex Haro, CEO of Hubble, joins Chris to talk about building a network of terrestrial and space (!) based Bluetooth infrastructure to track low power devices across the globe, without a data plan or a GPS module onboard.

Dave and Chris discuss a massive “boat anchor” warehouse clearance, 0201 board assembly, Texas Instruments’ stealthy datasheet updates for classic op-amps, the latest in local AI models, and paper-based electronics art

Massimo Banzi is co-founder of Arduino, the worldwide project built upon easily accessible embedded hardware. He joins Chris to talk about the design, rise, struggles, and eventual exit of the company, and what he’s now doing with Supermoderno.

Michał Zalewski (lcamtuf) is a security researcher, author, electronics enthusiast, and calculator collector. He joins Chris to talk about his new book The Secret Life of Circuits and his interest in the field of electronics and explaining things to others.

Dave and Chris discuss the infrastructure and massive energy demands of AI data centers, injecting power through a programming header, Linux changes, and dogfooding your own projects.

Jason Kridner returns to The Amp Hour after his first appearance 15 years ago to talk about the BeagleBadge and Zepto boards that showcase new capabilities in the Linux and Zephyr space. The BeagleBoard.org project is still focused on building open source, affordable, and accessible Linux and embedded hardware.

Past guests Matt Liberty (Joulescope) and Luke Beno (Werewolf.us) join Chris to talk through using AI tooling for small businesses in the hardware and firmware space. Both have built custom ERP systems, among many other tooling for their businesses, in a fast moving environment.

Julia Desmazes joins Chris to discuss designing chips for fun and getting an entire design done in 2 weeks to make a tapeout deadline. Julia built accerlators and has continued to dive deeper into on and off chip tooling for greater visibility into the silicon she gets back from the fab.
