I use KF7I here.
My interests tend to meet where practical systems, security, radio, infrastructure, and machines overlap. I like taking complicated things apart, learning how they behave in the real world, and documenting the parts that might be useful later.
This site is a working notebook rather than a complete biography. Expect new projects, technical experiments, field notes, and the occasional deep rabbit hole.
I deliberately keep personal details off this site. Posts should stand on their own without publishing private addresses, schedules, employer information, family details, personal contact data, or other information that does not need to be public.
The browser diagnostics on the home page run locally. They do not request device permissions or precise location. Public IP lookup is optional and happens only after the visitor chooses to reveal it.
