A small corner of the internet

Welcome to lab242.

Wireless by day, bees and campfires by weekend, a little bit of Japanese in between. This site is where I collect notes from all of it.

About

I grew up around radios and curiosity and never quite got rid of either. These days I spend my weekdays designing the invisible infrastructure that keeps phones working in places where they really, really shouldn't — and my weekends on things that move much slower: bees, campfires, kanji flashcards.

I started out writing code, studied a bit of AI, and although I stepped away from both as a career, they still quietly show up in everything I do.

Work

Wireless telecommunications, with a focus on indoor DAS in large venues — the kind of places where tens of thousands of people pull out their phones at the same time and expect it to just work.

Indoor DAS design

RF planning, head-end to remote, commissioning, and the long patient work of making coverage actually hold up under real crowds.

Large venue deployments

From planning drawings to a live network, with every cable and calibration in between.

Background in code & AI

Former programmer; a few years of AI study. I don't write production software anymore, but I still think like someone who does.

Bees 🐝

Three hives in the backyard. Honey comes out twice a year, and so does a humbling amount of perspective.

Beekeeping is the slowest hobby I have and probably the most rewarding. A colony teaches patience without ever raising its voice. I'll post harvest notes and a few pictures here as the seasons roll through.

A stacked Langstroth beehive in the backyard, framed by lemon trees, with a deer-shaped stone birdbath in the foreground.
The big hive, among the lemon trees. The stone deer keeps watch.
A Flow Hive mid-harvest: honey streams from the taps into a five-gallon bucket below, the frames visible through the back window.
Harvest day at the Flow Hive. Open the taps and the honey does the rest.
A cluster of honey bees hanging in a teardrop shape from a wooden pergola in the garden — a classic swarm.
A swarm settled on the pergola one evening. Thousands of bees, perfectly calm, just waiting for the scouts to pick a new home.
A frame of honeycomb pulled from a hive during inspection, covered in bees, with capped honey around the edges and a beekeeper's gloved hand holding it.
Inspection day. Capped honey around the edges, brood in the middle, thousands of workers doing what workers do.

Lid off, inner cover moved aside. The frames line up like books on a shelf — and the bees, mostly unbothered, carry on.

Camping ⛺

The antidote to the RF world. Off-grid, no signal bars, exactly the point.

There's more good camping out there than one lifetime can cover, but I'm working on it. Trip notes and favorite spots will land here over time.

A campfire burning low in a stone-ringed pit on the beach at dusk, picnic table nearby, waves rolling in behind.
Beach camp. A small fire, a picnic table, and the Pacific doing its thing.

Japan & Japanese 🇯🇵

Traveling to Japan more and more, and studying the language weekly. Still very much a beginner.

This section will grow into travel notes, study progress, and whatever phrase I'm currently struggling to remember.

はじめまして。 Hajimemashite. — Nice to meet you.

Osaka Castle main keep, white walls and gold accents under a blue sky with scattered clouds, pine trees in the foreground.
大阪城 — Osaka Castle. Still impressive every time.

Tools & Projects 🛠️

Small experiments I host here on the Pi. Most are password-gated — built for me, left online because taking them down feels wasteful.

📶

Coverage Surveyor

🔒

Drive-test data viewer for QualiPoc measurement files. Renders 50K+ RF samples on an interactive map, color-coded by RSRP, RSRQ, TX power, PCI, or band, with viewport-aware filtering and live KPIs. Built for venue-scale coverage analysis.

📈

Regime Classifier

🔒

Hidden-Markov-Model market regime detector. Enter any ticker, get an honest walk-forward backtest vs. the flashy in-sample version vs. buy-and-hold — the differences tell you more about why so much “quant content” online is misleading than any essay could.
