What this episode covers

Matt Liberty, founder of JetPerch LLC, discusses the launch of the Joulescope JS220, an upgraded high-dynamic-range current and voltage measurement device. He details the hardware evolution from the JS110, including the switch to a Lattice ECP5 FPGA, a Cortex-M7 microcontroller, and a 16-bit ADC, while explaining the custom firmware architecture and publish-subscribe protocol. Liberty also shares his experiences navigating the global chip shortage, managing supply chain risks with PartsBox, and the financial pressures of bootstrapping a hardware business.

    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.
