The Place Where Modern Operations & Technology Come Together
Smart Ring Development (Part 1) Research and Prototype
This series of articles discusses the development of a SOTA Open Smart Ring － a tiny wearable packed with electronics that fits on your (even the smallest) finger. We dive deep into what it means to develop such a product, its challenges, and ultimately, how to make it a manufacturable and usable piece.
Why Building Tools for Developers Starts With Your Own Pain
Maximilian Köhl shares how his frustration with complex update systems led him to build for embedded developers like himself. When devs build tools they need, the whole ecosystem benefits.
The Role of Precision Engineering in Modern Valve Manufacturing
Valve manufacturing enables the production of components that meet stringent industry standards and customer expectations. The demand for high-quality valves has grown in many sectors, including but not limited to oil and gas and pharmaceuticals. With the increasing complexity of designs and the necessity for reliability, precision engineering offers the tools and methods to achieve excellence in valve production. See how precision engineering shapes modern valve manufacturing, the benefits it brings, and the emerging technologies that improve its effectiveness in the industry.
Why Zephyr Helps When Switching Between MCUs
Martin explains why he moved to Zephyr after running into deprecated SDKs and the pain of restarting every time he switched MCUs. Zephyr offers consistency when platforms change.
COREDUMP #010: From Pebble to Intel Can hardware startups beat the big players
In today's Coredump Session, we explore the wild early days of Pebble and what it takes to scale a hardware startup against industry giants. From scrappy hackathons to 100+ person engineering teams, Kean Wong, former VP of Software at Pebble and now CTO at Eagor, joins Memfault’s François and Chris to unpack how startups can outpace Big Tech by staying nimble, hiring wisely, and embracing constant change.
How Adaptive OTA Updates Work Without Extra Infrastructure
Maximilian Köhl breaks down how RugX uses adaptive data updates to deliver deltas without heavy infrastructure. No static compression or custom pipelines—just smart chunking and HTTP range requests.
Why OTA Updates Are So Hard on Embedded Linux
Pat Wolfe explains the gap in expertise and tooling for embedded Linux OTA systems. He shares how RugX makes it easier to get robust A/B and delta updates running without deep U-Boot work or complex board configs.
Successful Launch - Then Came The Problems
About 15 years ago, I worked at a company building network security appliances (with ARM-based network processors) and was responsible for the development of custom Linux firmware. The product launch was successful; we shipped and managed a large fleet of devices in the field. After a few firmware releases, we received alerts from the device management system telling us that there were intermittent problems. Remoted into the appliances but could not reproduce the error.
Is Zephyr the Right Fit for Your Project?
Curious about when Zephyr isn't the right choice and what alternatives exist? Explore why some projects might not suit Zephyr's 32-bit architecture and discover the flexibility it still offers for managing edge devices intelligently. Dive into the decision-making process for your next embedded project.
