Lucas and Luna sit down at a lab bench cluttered with oscilloscopes and prototype boards to talk about the engineering decisions that shape the chips powering modern life. Each episode takes one piece of hardware — a new RISC-V core, a GaN power amplifier, a MEMS accelerometer — and examines its design trade-offs, yield challenges, and market positioning. They discuss why Intel’s 20A node matters for foundry customers, how TSMC’s CoWoS packaging affects AI accelerator supply, and what the CHIPS Act subsidies mean for domestic fab construction. Lucas brings the component-level knowledge (threshold voltages, die sizes, lithography steps); Luna pushes on the system-level implications (thermal constraints, software compatibility, supply chain risk). The listener is someone who reads datasheets for fun, follows EDA tool announcements, or needs to decide between an FPGA and an ASIC for their next product. No hot takes on Apple’s latest chip — just a careful look at what the die shot reveals

How Chip-Scale Lasers Are Shrinking Medical Diagnostics
Aug 18, 202610 minS4
In this episode of The Hardware Podcast, Lucas and Luna dive into the world of chip-scale external cavity diode lasers and how they're transforming medical diagnostics. They focus on a breakthrough from a research team at the University of California, Santa Barbara, that has integrated a tunable laser onto a silicon photonics chip, achieving a linewidth of just a few kilohertz. This innovation could make optical coherence tomography, or OCT, affordable and portable, bringing high-resolution imaging to clinics and even field settings. The hosts explain the physics behind the laser, compare it to traditional benchtop systems, and discuss the manufacturing challenges that remain before these chips can be mass-produced. They also touch on the broader trend of shrinking complex optical instruments into handheld devices, from spectrometers to atomic clocks. If you're curious about how cutting-edge photonics is about to change healthcare, this episode is for you. #ChipScaleLasers #MedicalDiagnostics #OpticalCoherenceTomography #SiliconPhotonics #ExternalCavityDiodeLaser #TunableLaser #UCSBResearch #PhotonicIntegratedCircuits #PortableMedicalDevices #SemiconductorLaser #BiomedicalOptics #Technology #Hardware #FexingoBusiness #BusinessPodcast #ScienceInnovation #Engineering #FutureOfMedicine Keep every episode free: buymeacoffee.com/fexingo
In this episode, Lucas and Luna dive into the world of chip-scale microfluidics — the technology that puts entire laboratories on a fingernail-sized chip. They explore how these devices manipulate tiny volumes of fluids, from picoliters to nanoliters, and why that matters for everything from DNA sequencing to drug discovery. Lucas breaks down the physics: laminar flow, capillary action, and the famous 'lab-on-a-chip' concept, using the example of a droplet-based PCR chip that amplifies a single DNA molecule. They also discuss the practical challenges of manufacturing these chips at scale, comparing the approaches of key players like Fluidigm and Oxford Nanopore. The conversation touches on how microfluidics is accelerating research in genomics and point-of-care diagnostics, and what it means for the future of medicine. If you've ever wondered how a tiny chip can replace a roomful of lab equipment, this episode explains it all with clarity and enthusiasm. #ChipScaleMicrofluidics #LabOnAChip #Microfluidics #LabChip #Genomics #DNA #PCR #DrugDiscovery #PointOfCare #MedicalDevices #Biotech #Fluidigm #OxfordNanopore #LaminarFlow #Droplet #Technology #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo
How Chip-Scale Atomic Magnetometers Are Shrinking Brain Scanners
Aug 16, 202610 minS4
In this episode of The Hardware Podcast, Lucas and Luna dive into the latest breakthrough in chip-scale magnetometry: a portable magnetoencephalography (MEG) system that can map brain activity without a superconducting room. They explore how optically pumped magnetometers (OPMs) built on silicon photonics are replacing the bulky, cryogenically cooled sensors of the past, enabling real-time imaging of neural currents in a backpack-sized device. The conversation covers the physics of spin precession, the manufacturing challenges of integrating tiny vapor cells into CMOS, and the potential for wearable brain-computer interfaces and affordable neuroscience in clinical settings. With a focus on the recent prototype from a Stanford spinout, they explain why this could democratize brain imaging and open new frontiers in neurofeedback and psychiatric diagnosis. Tune in for a deep yet accessible look at how chip-scale atomic physics is turning science fiction into lab-equipment reality. #HardwarePodcast #ChipScaleSensors #AtomicMagnetometers #MEGBrainScanning #SiliconPhotonics #CMOSIntegration #Neuromonitoring #BrainImaging #QuantumSensors #StanfordSpinout #PortableMedicalDevices #Neuroscience #BCI #BiomedicalEngineering #Technology #EngineeringPodcast #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo
How Chip-Scale Spectrometers Are Shrinking Food Safety Testing
Aug 15, 202610 minS4
From farm to fork, food safety testing has always been a slow, lab-bound process. But a new generation of chip-scale spectrometers is changing that. In this episode, Lucas and Luna explore how a tiny near-infrared spectrometer, no bigger than a sugar cube, can detect adulteration in olive oil, verify the authenticity of honey, and even scan a cut of beef for spoilage — all in seconds, right at the point of sale. They trace the technology from its roots in benchtop instruments to the latest integrated photonics, and discuss the challenges of making these devices cheap enough for every grocery store. Along the way, they consider the regulatory hurdles and the potential for consumer-level food fraud detection. If you've ever wondered how your food gets tested, this episode will show you the chip that's about to make it faster, cheaper, and more accessible than ever. #ChipScaleSpectrometers #FoodSafety #NearInfraredSpectroscopy #Photonics #FoodFraud #OliveOilTesting #HoneyAuthentication #PortableSensors #Technology #Hardware #ElectronicsEngineering #Semiconductors #AgTech #SupplyChain #FoodQuality #FexingoBusiness #BusinessPodcast #Innovation Keep every episode free: buymeacoffee.com/fexingo
How Chip-Scale Force Sensors Are Making Robots Feel
Aug 14, 202611 minS4
In episode 155 of The Hardware Podcast, Lucas and Luna explore the surprisingly tactile world of chip-scale force sensors—the tiny silicon devices that let robots, surgical tools, and even smartphones feel pressure, grip, and touch. They open with a specific moment: a robot arm in a lab gently picking up an egg without cracking it, made possible by a sensor that measures micro-Newtons of force. Lucas breaks down the physics—piezoresistive and capacitive designs, MEMS fabrication, and the challenge of measuring force without adding bulk or cost. Luna digs into the clinical angle: how force-sensing catheters are changing cardiac ablation procedures, and why haptic feedback in prosthetics is the next frontier. They touch on the business side too, from the incumbent players like Tekscan to the startups racing to commercialize tactile sensors for robotics in 2026. The conversation stays grounded in engineering specifics—bridge circuits, drift, calibration—while connecting to the bigger promise: machines that can feel the world as precisely as we do. A pragmatic look at a quiet revolution in sensing. #ForceSensors #MEMS #Robotics #Haptics #MedicalDevices #SurgicalTools #Prosthetics #Piezoresistive #CapacitiveSensing #TactileSensors #RobotGrippers #SensingTechnology #Hardware #Engineering #TechPodcast #FexingoBusiness #BusinessPodcast #Innovation Keep every episode free: buymeacoffee.com/fexingo
