    The Spark Gap - Episode 32

    Hosts Carl and Corey revisit topics from their first 31 episodes, discussing the NXP acquisition of Freescale, MakerBot's layoffs, and Tesla's certified pre-owned program and Powerwall. They also analyze the John Deere firmware ownership controversy, the performance trade-offs of No-OS and Lua on microcontrollers, and the evolution of the Raspberry Pi. The episode highlights specific components like NXP current-sensing MOSFETs and the PCA8550 I2C dip switch, while addressing software bugs in Boeing 787 generator control units and the importance of checking simple parts like LDOs.

    Pneumatic Tubes, Straight To The Home

    Dave Jones and Chris Gammell discuss recent tech hype, including debunking viral claims about the 'Water Cube' dehumidifier and beta-voltaic 'nuclear diamond' batteries. They cover the merger of Evil Mad Scientist and Bantam Tools, a side-channel security vulnerability affecting ESP32 microcontrollers, and the acquisition of a used TVM pick-and-place machine. The conversation also touches on power grid issues, CAD software choices like Fusion 360 and Onshape, and the failure of solar roadways.

    The Spark Gap - Episode 44

    Hosts Carl and Corey discuss a grab bag of embedded electronics topics, starting with their new remote recording setup using Shure and MXL microphones. They review the TI ADS1263 32-bit ADC and the Lattice iCE40 FPGA ecosystem, highlighting the open-source Project Ice Storm toolchain. The hosts then critique the Raspberry Pi Zero's limited I/O and the safety issues surrounding lithium-ion batteries in 'hoverboards', before Corey airs a grievance about poor PCB differential pair routing practices.

  • The Amp Hour

    The RP2350 with the Raspberry Pi Team

    James Adams, Chris Boross, Liam Fraser, and Luke Wren from the Raspberry Pi team discuss the RP2350 microcontroller, detailing its evolution from the RP2040 with a focus on new security features, low-power modes, and the addition of a RISC-V core (Hazard 3). The team explains the architectural challenges of integrating dual cores, the enhanced Programmable I/O (PIO) subsystem, and the implementation of secure boot with hardware countermeasures against fault injection. They also share insights from a recent security challenge, revealing exploits like passive voltage contrast on OTP memory, and discuss the future of the RP2040 and upcoming Pico 2 variants.
