    Measuring Current with Matt Liberty

    Matt Liberty, creator of Joulescope, explains the engineering challenges of measuring high dynamic range currents in low-power IoT devices, specifically addressing the difficulty of switching between milliamp active states and microamp sleep states. He details how Joulescope uses a shunt ammeter design with seamless auto-ranging to minimize burden voltage, preventing device brownouts, and leverages Lattice iCE40 FPGAs for precise, sub-microsecond switching. The conversation covers practical applications for optimizing firmware power profiles, debugging leakage currents from components like bypass capacitors, and managing the supply chain and manufacturing processes for a small-batch hardware startup.

    Sipping Coulombs

    Dave Jones of EEVblog and Chris Gammell of Contextual Electronics discuss the business realities of hardware, including the bankruptcy of Chip Board and the supply chain constraints facing Jones's own multimeter production. They analyze the economics of low-cost single-board computers like Raspberry Pi and the challenges of designing for long battery life, using a hypothetical keychain device to illustrate power budgeting with primary lithium cells and BLE. The conversation also covers the culture of Defcon badges, debunking pseudoscientific wireless charging claims, and the importance of validating product requirements early.

    The Nerd Calendar

    Chris Gammell of Contextual Electronics and Dave Jones of the EEV Blog discuss the Narrative wearable camera, highlighting its low-power engineering challenges involving GPS, Wi-Fi, and battery life. They analyze the difficulty of measuring wide dynamic range currents in DC power analysis, noting that specialized equipment like the Keysight DC Power Analyzer is prohibitively expensive for general use. The conversation also covers the collapse of Theranos, the IEEE's acquisition of GlobalSpec, and practical advice for engineers regarding data sheets, jellybean components, and RF design.

    #018: The Hidden Complexity of Sleep Tech: Power, Comfort, and 8 Hours of Reliability

    Charles Taylor, co-founder of Ozlo Sleep, explains how his team revived Bose’s discontinued Sleepbuds by balancing extreme miniaturization, power efficiency, and firmware-driven reliability. He details the engineering challenges of designing earbuds smaller than AirPods that last 8-10 hours, the critical role of Kickstarter in building a beta community for real-world testing, and the strategic decision to pursue FDA clearance for software-based therapies rather than classifying the hardware as a medical device.
