How mixed-signal architecture decides whether your product records clean audio or captures the noise of its own electronics In a connected product, audio quality is often judged by the microphone, codec, and software processing algorithm. But many audio failures do not start in the microphone or the codec. They start
At 7:14 this morning, a smart feeding bowl logged something small: Max, a six-year-old golden retriever, left a third of his breakfast. His collar tracker says yesterday's walk was completely normal. A vet note from two weeks ago mentions mild tartar buildup. And a dog-nutrition book on
How aligning mechanical, electrical, and firmware engineering early helped us reduce redesigns, shorten decision cycles, and build a more reliable product. Introduction Most engineering problems don't belong to a single discipline. A mechanical engineer designs a bracket that blocks a connector. An electrical engineer relocates a PCB and
The problem Look at how the app handles daily habits today. The quiz has a streak. Paw Pulse gives you a fresh insight about your pet once a day. The journal keeps a running timeline of what happened, day by day. On the surface these look like three unrelated features.
Clamp placement, return-current control, connector-side protection, TVS selection, and transient energy budgeting User-facing ports are where the controlled environment of a product meets the unpredictable outside world. A PCB inside an enclosure operates with known voltages, controlled impedance, defined signal levels, and carefully planned current paths. The moment a user
How thoughtful design reduced repair time, simplified maintenance, and improved the ownership experience. Introduction Most hardware gets designed around one question: how do we assemble this? A much smaller number of products get designed around the equally important question of how do we take it apart. For consumer products, serviceability
At 3 a.m., a smart pet bowl in a customer's kitchen notices it hasn't captured anything in half an hour. The sensor path has quietly wedged — the kind of stall that, on a normal device, would sit there dead until someone noticed the app had
Whenever we build a new website feature, our first instinct is usually to think about a backend. We start planning REST APIs, database tables, authentication, deployment pipelines, and server infrastructure. For many applications, that's exactly the right approach because those components provide the flexibility and scalability needed for
In our previous post we built the first version of an ML bark classifier: 28 features extracted from collar IMU windows, a RandomForest winning a model bakeoff, bark F1 of 0.714 on a held-out test set. That number looked good. It was wrong. The Number That Was Lying to
Search is usually treated as a solved problem. Store the data, index the field you plan to query on, look it up. That holds up perfectly well right until the moment the words someone actually types don't match the words you indexed. The moment exact-match search quietly fails
