The Lab
Experiments, tools, and personal projects that don’t fit neatly under ham radio or software โ but were too interesting not to build.
RetireWise
A full-featured retirement planning calculator with Monte Carlo simulation, historical stress-testing across 11 real market periods (1929 Depression through 2022 Bear Market), tax-optimized withdrawal strategies, Social Security claiming analysis, healthcare cost projections, and Required Minimum Distribution calculations. Runs entirely in your browser โ no accounts, no data collection.
Open RetireWise โSpectrum Analyzer & Waterfall
An SDR-style spectrum analyzer with a scrolling waterfall display. Captures system audio via WASAPI loopback and renders both a real-time frequency spectrum and a time-scrolling waterfall โ the same visualization used in software-defined radio applications to spot signals over time. Useful for audio analysis, RF monitoring, and general curiosity.

An ongoing English translation of my father Constantin Marghitoiu’s philosophical treatise. “Vidฤ” means void or vacuum in Romanian โ the work explores the nature of perception, consciousness, and the structure of experience through a systematic framework built across 13 chapters. Originally written in Romanian, the full manuscript runs approximately 90,000 words. Translation is currently ~9% complete, with Part I and Part II (sections 2.1โ2.3) finished.
