Ep 304: Glitching the RP2350, Sim Sim Sim, and a Scrunchie Clock

Hackaday Podcast · 17 Jan 2025 · 59m · Episode 304

What this episode covers

Hosts Elliot Williams and Dan Maloney review recent Hackaday projects, including Aiden Cullen's successful fault injection attack on the RP2350 microcontroller to access hidden security memory, and Mitzella's fluid simulation pendant. They also discuss a Manhattan-style direct conversion radio, an ESP8266-based fault injection coordinator, and Ed Karatsis's mechanical 'Scrunchie Clock' that uses hair springs to display digits. The episode covers various engineering challenges, from bypassing anti-glitching circuitry to designing mechanical cams for digital displays.

    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.

    It Works With Option Number 5

    Dave Jones and Chris Gammell discuss a useless wrist-worn multimeter, the educational value of visual tools like Blender and quantum diamonds, and the pitfalls of camera review content. They detail Dave's struggles with a DI hybrid solar inverter's drifting internal clock and Chris's hack day project implementing a remote shell for Zephyr OS devices using Golioth. The conversation concludes with a comparison of Australian and US electrical systems and a lesson on hysteresis from a car's low-temperature warning.
