A collar microphone can't tell whose bark it just heard. It picks up every sound within range, the dog wearing it, the beagle three doors down, the TV in the background. An audio classifier running on the firmware can label a sound as "bark," but it
Why clock gating and controlled pull strategies matter more than you think One of the most frustrating problems during embedded hardware bring-up is a system that behaves perfectly after initialization but randomly fails during power-up. The firmware loads correctly, communication works, and every subsystem appears healthy, until one cold boot
How do you count a dog's steps when the dog might be a four-kilogram terrier or a sixty-kilogram mastiff, walking, trotting, or flat-out galloping? You can't hard-code a step frequency, because there isn't one, a small dog's legs cycle nearly twice as
A pet parent opens EverWiz chat and asks, "Is Milo overdue for his rabies booster?" A generic LLM can write a thoughtful essay about rabies vaccination schedules. What it can't do out of the box is look at this specific pet's actual vaccination card
A pet wearable has one job above all others: be awake when something happens. A dog doesn't schedule its zoomies, and a collar that has quietly wedged itself into an infinite loop is, for all practical purposes, dead, it just hasn't fallen off the dog yet.
Every hardware product starts as a prototype, but a prototype and a product are solving fundamentally different problems. A prototype answers "can this work?" A product has to answer something much harder: can this be built repeatedly, assembled efficiently, shipped reliably, and trusted by users over time? While
In the early stages of hardware development, it's incredibly common for engineers to imagine assembly as a perfectly linear, flawless process. Components arrive exactly on time, boards get populated in a strict sequence, firmware is flashed immediately after assembly, cables are connected correctly, and every subsystem powers on
A collar-worn pet tracker lives in about the most hostile environment a storage engineer could design on purpose. The battery is tiny, the dog is unpredictable, and the wireless link to the hub drops every time the dog wanders behind the couch. Now picture the worst possible moment: the battery
The pipeline ran. Interrupts fired. DMA counters incremented. Every status register said the system was healthy. The buffers were empty. Three days of debugging, one register field.
A step counter on a dog's collar sounds like it should be a solved problem. After all, human pedometers have shipped in phones and watches for over a decade. But a dog is not a human walking upright with a phone in their pocket. The sensor sits on
