In our first post on the bark detection pipeline, we showed how a single threshold on jerk_3d_max gives a useful signal for detecting barks from a dog collar IMU. For any capture window where jerk_3d_max crosses 6.5 g/s, the rule calls it a bark.

Why pin assignment is not just routing convenience Dense connectors look harmless on a schematic. A row of pins. A few high-speed lanes. Some power. Some ground. A few control signals. Maybe an I2C bus, reset, interrupt, enable lines, and one or two spare pins. Everything fits. Then the board

A pet's day has a soundtrack, and most of it is health data. The rhythmic crunch of kibble, a gulp of water, a bark at the doorbell, the wet cough that wasn't there last week — each is a signal a vet would want to know about.

Not every safety check belongs in the same place. Some only make sense on the user’s question, some only on the model’s answer, and some on both. Here is how we structure the guardrails on our veterinary chatbot — and why the input/output split matters. A guardrail isn’

A fleet of connected devices is a relentless text generator. Every device runs a dozen cooperating services, and each one narrates its life in log lines: startup banners, retries, sensor readings, stack traces. Across a hundred-plus devices that adds up to hundreds of thousands of lines a day, spiking into
Hardware
Timing discipline during voltage transitions Power does not become stable in one instant. A board may receive input power, but the internal rails are still ramping. A regulator may be enabled, but its output has not yet reached tolerance. A level shifter may see one side alive before the other.
Most production incidents do not begin with faulty application code. They begin with infrastructure changes that nobody fully understood. A security policy modified through a cloud console. A manual configuration update made during an urgent fix. An environment that slowly diverges from the documentation intended to describe it. Individually, these

In product development, performance improvements are often associated with new electronics, better sensors, or more sophisticated algorithms. Occasionally, however, the solution comes from something much simpler. A few millimeters of geometry. During the development of one of our wearable tracking devices, we encountered an issue that initially appeared to be

A thermal camera can see a fever before a dog acts sick — but only if you know which warm pixels belong to the dog. A low-resolution thermal sensor and a normal camera look at the same scene from slightly different places, through different lenses, at different resolutions. Point them at

How Real-World Use Drove Mechanical Design Decisions No matter how carefully a product is engineered, its first encounter with real users almost always reveals something the design team did not anticipate. Engineers interact with products differently than users. During development, devices are handled deliberately, assembled with care, and operated according
