An Interview With Andrew Witte - Telistic Timepiece Technomania

The Amp Hour · 11 Dec 2013 · 1h 23m · Episode 175

What this episode covers

Andrew Witte, CTO of Pebble Technology, discusses the design and manufacturing of the Pebble smartwatch, which raised $10 million via Kickstarter. He details the engineering trade-offs, including the choice of a Sharp Memory LCD for low power consumption, the challenges of Bluetooth antenna performance on a wrist, and the decision to use a single-cell lithium battery with a boost converter. Witte also explains the transition from local prototyping to overseas manufacturing with Dragon Innovation, managing component lead times, and the technical implementation of third-party app sandboxing using a Memory Protection Unit on an ARM Cortex-M3 microcontroller.

    T-26-012 : Founders From The Show Floor - CES 2026

    Chris and Nate interview founders from Eureka Park at CES 2026, including Rajeev Ramanath of Blueberry Technology, Cole Ashman of Pila Energy, and Scott Hickle of Throne. They discuss specific products like the autonomous Blueberry Go airport robot, Pila Energy's modular home batteries, and Throne's toilet health tracker. The episode highlights trade-offs in hardware design, such as Pebble's Eric Migicovsky choosing ODMs for speed over control, and Roam's Aaron Pollack accepting thickness for battery life. Other founders like Niclas Bertelsen of Naya and Michael Churchill of Kombu discuss modular ecosystems and material choices for fermentation.

    #006: Pebble’s Code is Free: Three Former Pebble Engineers Discuss Why It's Important (PART 2/2)

    Brad Murray, former head of Pebble firmware, and Tomas, former developer evangelist at Pebble, discuss the risks and decisions behind building firmware for Pebble smartwatches. They detail a critical OTA update bug that nearly bricked nearly a million devices, which was recovered using a clever BLE-based stack overflow hack. The team also explains how they built a massive developer ecosystem through tools like CloudPebble and the Watch Face Generator, and how they optimized code size to backport Pebble 3.0 to legacy hardware using techniques like Link Time Optimization and bootloader rewriting.

    #003: Pebble's Code is Free: Three Former Pebble Engineers Discuss Why It's Important (PART 1/2)

    Francois Baldassari, Chris Coleman, and Brad Murray, former engineers at Pebble, discuss the technical architecture and engineering decisions behind PebbleOS. They explain how a single codebase supported multiple hardware variants, enabling a platform approach that simplified updates and app compatibility. The team details their custom NOR Flash file system, app sandboxing using MPU fault handlers, and the strategic use of intentional crashes to generate core dumps for debugging. They also highlight the importance of analytics, serial protocols, and the collaboration between firmware and hardware teams in shaping the final product.

    #008 - What to learn from Pebble’s story: two times most funded Kickstarter campaign ever to its eventual end, with your host, Balint Horvath, Switzerland

    Host Balint Horvath analyzes the rise and fall of Pebble, the company that produced the first smartwatch and held two record-breaking Kickstarter campaigns. He argues that Pebble failed because it could not cross the chasm from early adopters to the early majority, specifically by missing the fitness application that competitors like Fitbit capitalized on. Horvath discusses the strategic errors regarding pricing, the lack of a recurring revenue model, and the failure to build a strong emotional brand or a 'system of progress' ecosystem.
