Chris Gammell hosts a reunion with past guests Alvaro, Dave Jones, and Ariel Briner to discuss the state of electronics in 2023. The group covers trends in robotics, IoT, and embedded firmware, with Alvaro detailing his work on ocean buoys using STM32 and Blues Wireless modules, and Dave Jones discussing his scaling Electron Labs. They also debate the utility of AI in engineering, the rise of RISC-V, and specific debugging challenges like Unicode handling in cellular modems and SSID-related crashes.

Hosts Alicia White and Christopher White discuss listener questions regarding USB implementation challenges, IoT security thesis advice, and prototyping strategies. They analyze the differences between ARM microcontroller vendors, code reuse in embedded systems, and the utility of tools like audiomovers.com for remote audio collaboration. The episode also touches on personal coping mechanisms for stress and motivation during the pandemic.
Hosts Elecia White and Chris Svec discuss listener emails, covering topics from the SpaceX Falcon Heavy launch to the Chordbot sequencer controller from Isla Instruments. White shares her experience writing 'Making Embedded Systems' and addresses a reader's request for resources on interrupts and timers, while also reviewing educational YouTube content and the free STM32 TrueStudio IDE. The conversation concludes with reflections on corporate product cancellations at LeapFrog and Cisco, and the technical optimization of early Pokémon games.
Hosts Elecia White and Christopher White answer listener emails, covering topics from I2C pitfalls and RTOS choices to advice for students and engineers dealing with legacy code. They discuss the 'March Micro Madness' dev kit tournament, automation in embedded testing, and the challenges of refactoring a 60,000-line monolithic codebase. The episode also includes career advice for undergraduates and a discussion on short stories.
Hosts Elecia White and Christopher White discuss the technical implications of the 2038 time bug, the utility of the 'single-file libraries' GitHub repository for embedded development, and Christopher's hands-on MIDI project using an STM32 NUCLEO-144 board. Elecia also shares her exploration of Tiny ML for PID controller tuning and her attempt to apply for a NASA NIAC grant using curved crease origami for sensor systems.
Hosts Elecia White and Chris White discuss a wide range of embedded systems topics, including sourcing components from distributors like DigiKey and Seeed Studio, and using tools such as Visual Studio Code with the Cortex-Debug extension for STM32 development. They analyze the engineering challenges of accelerometer-based crash detection in iPhone 14 and Apple Watch, referencing a past Fitbit rollercoaster bug, and debate the industry's transition from C to Rust. The conversation also covers career advice for embedded engineers, the use of AI tools like DALL-E for content, and the importance of systems engineering and documentation.
