If it didn't compile, it doesn't get shipped.

I'm Joe Lundgren. I've spent the last seven years writing firmware in consumer electronics, with an MS in Computer and Electrical Engineering from Johns Hopkins. Somewhere along the way I got tired of debugging the same "definitive ESP32 tutorial" for the third colleague and started keeping a bench notebook.
This site is that notebook, opened to the public. Every entry is bench-tested against a logic analyzer, a power profiler, and an oscilloscope before it is allowed to be published. If the numbers in a tutorial don't match the numbers on my bench, the tutorial doesn't ship.
Every code snippet on this site builds, runs, and produces the documented output. Snippets are pulled directly from the bench rig that produced the screenshot.
If a tutorial claims 11.8µA in deep sleep, that's a PPK2 reading, not an Espressif datasheet number. Every quoted figure has a screenshot link.
