Edge AI on a microcontroller, minus the hype
What actually fits on a small part, what does not, and why memory rather than compute is the real constraint.
Engineering Notes
Short technical notes from ongoing work.
Why small embedded systems still avoid Linux
An operating system solves problems a small device does not have, and creates several it cannot afford.
Chiplets, explained without the marketing
Why the industry took one large die and cut it into several, and what that has to do with yield.
How a memory shortage reaches a bill of materials
You are not buying HBM. You are still paying for it. The mechanism, and what to do about it at design stage.
EMC is decided at layout, not at the test house
By the time a board fails a pre-compliance scan, most of the decisions that caused it were made weeks earlier.
What broadcast audio actually changes for hearing loss
Induction loops have served for decades. What Auracast improves, and what it does not solve yet.
Capacitors: still the first thing to check
Most equipment that fails after twenty years fails for the same reason, and it is rarely the interesting part of the circuit.
Lossless, hi-res, and what actually reaches your ears
The file is rarely the weak link. A short, unromantic look at where audio quality is actually lost.
