Digital-mode logbook
Structure, ADIF interoperability and robustness before any 1.0.
Marcelo Trindade / DevNux
Curiosity applied to the real world.
Observing systems. Building tools. Recording what is worth not forgetting. DevNux is a living personal archive for following ideas while they change state.
Now · 19 Aug 2026
What is on the bench.
Not a calendar. A snapshot of what is receiving attention right now.
Organizing
DevNux as a personal archive
Trails, experiments, notes and history living in the same place.
Exploring
Digital radio infrastructure
Hotspots, WPSD, Pi-Star and lean hardware for experimentation.
Recent records
Time is part of the content too.
New entries leave a trail instead of disappearing behind the next update.

CurrentThe structure starts prioritizing process, state and history.
Por que este caderno existe
The first Caderno note, in Portuguese.
Trails
Subjects as paths, not departments.
Each trail works as an index for records, experiments and notes related to the same field.
Environment
Water, territory, sanitation, restoration and observation of place.
Technology
GNU/Linux, open software, programming, electronics and automation.
Amateur radio
PU2OMT · GG69CP · digital modes, CW, RF and infrastructure.
Meliponiculture
Native bees, responsible management, conservation and flowering cycles.
Experiments
Work in progress has a place of its own.
Software, infrastructure and ideas may appear before they are finished, with explicit status and without portfolio theater.
Radio / software
Digital logbook
A logbook focused on digital modes, with interoperability as a central requirement.
System
DevNux
The site itself treated as a personal archive, not a showcase.
Caderno · PT-BR
Notes from the road, without an editorial calendar.
Tests, observations and things worth recording before they disappear between one curiosity and the next.
Archive / identity
What remains when the home page changes.
The archive organizes time. Identity concentrates verifiable references, contact channels and public keys.
