The local web UI: FastAPI inside the app

A physical knob would be optimal. Building one, not. I put the UI in the browser and made it reachable from any device on the LAN.

The trip becomes a blog

The blog used to be flat text you read once and forgot. The recall mode turns it into the trip's artifact: editable blocks, your own photos, and a PDF you can take with you.

Observing without seeing the user

I need to know what broke. I don't need to know whose screen broke. That distinction defines the entire observability layer.

BMAD: plan before writing code

If I just write code, I lose the thread by week three. If I over-plan, I lose it sooner. I had to learn to plan without drowning in planning.

Three repos, one promise

Three modes in the product; three repos in the code. Not a coincidence. The same instinct applied twice: separate the things that move at different speeds.

Host architecture: events, settings, scheduler

Three decisions changed how I think about this host. None is dramatic on its own. Together, they make all the difference.

Fuel: real data over the map

A pretty map isn't a product. A map that saves you twelve euros by filling up 4 km further down is. The trick lives in the combination prices + corridor + camper.

Why a binary protocol (and not JSON)

The easy option was JSON. It was also the option that made 30 FPS physically impossible. A six-byte-overhead binary protocol clears the bottleneck.

Geofence: knowing you arrived without you saying so

A check-in is the silliest piece of friction in software. Always-on GPS is surveillance. In between lives the geofence with a dwell window.

POIs that surface on their own

An empty planner is intimidating. A planner that already populates the corridor — with everything you don't like removable — is a conversation.

Planning and driving are two different brains

A dense screen that works at home with coffee is unreadable in the cab with the sun overhead. The temptation was a toggle. The temptation was wrong.

From script to product

There was a 200-line script. It worked. The story did not end there — without the next step, there would be no family.

What CamperRoute is

I set out to organise a camper trip. I ended up designing a product with three modes. This post explains why three were necessary.

What Lumware is

I set out to blink a few LEDs. I ended up designing a software family for programmable light strips.

The firmware: Arduino and critical timing

An Arduino Uno has 2 KB of RAM. A 300-LED strip is 900 bytes just for pixel buffers. Every decision is a question of space.

Identity: spectrum R/G/B/W
