    278: Bricks' Batteries Last Forever (Repeat)

    Matt Liberty, founder of Jet Perch, discusses the design and development of Joulescope, a high-precision current measurement tool launching via Kickstarter. He explains the engineering challenges of measuring dynamic ranges spanning nine orders of magnitude, from nanoamp sleep states to amp-level active currents, and how standard multimeters fail due to burden voltage and resolution limits. The conversation covers software strategies for low-power embedded design, such as managing GPIO states and clock speeds, and details the hardware innovations in Joulescope, including its auto-ranging shunt resistors and electrical isolation.

    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.
