  • It would be too inaccurate to fingerprint a specific vehicle based on the waveform generated as it drives over a coil sensor like this. For example, if your car drives over it one day and then drives over the same coil but 20cm to the left, the waveforms would be different enough already that they couldn’t be statistically correlated. A large truck driving over an edge could look like a small car driving directly through the middle. These kinds of sensors are really only useful for saying a big chunk of ferromagnetic something passed by.





  • If you are wanting to learn more Linux internals AND create something maintainable, you can create your own distro using Yocto/Bitbake. LFS teaches you all about Linux internals, but kind of leaves you to twist in the wind afterward. I would argue that Yocto exposes those internals AND gives you the ability to maintain the distro you’ve created (roll your own packages, pull in kernel patches/versions/modules, scan for applicable CVEs, etc.)

    Or Gentoo sounds cool. Maybe an easier intermediate step before rolling your own.
