Notes on building small digital projects, tools, and systems.
Shipping the Swedish cut into an empty room
The Swedish version of the Fable 5 video is finished — and the model it's about got pulled offline before it could go up.
From eval to release video in two days
The island eval became a YouTube video about Claude Fable 5 — built with forced alignment, segment-wise HeyGen renders, and a butterfly that took four tries to crop.
My first eval challenge: one island brief, two AIs
I gave the exact same five-step brief — island demo, ecosystem simulation, four languages, deploy, film it — to Fable 5 in Claude Code and to ChatGPT, and got two very different islands back.
Cobalt: an AlphaZero bot for Azul, and the plateau it took a research paper to break
Building a self-taught Azul bot from scratch — the collapse, four training rounds that went nowhere, and how Gumbel AlphaZero plus a lot more self-play finally broke through.
Pi, in three languages
One 3-minute explainer about a minimalist coding agent, shipped in English, Swedish, and Japanese in a single session — plus the small disasters along the way.
The screen was the easy part
Buying a monitor through the company turned a simple purchase into a lesson in ergonomics, EU reverse-charge VAT, and why business credit cards cost extra.
Measure before you buy — and know when the cutoff matters
Optimizing the workstations we already have at home turned into a lesson in not guessing: the bottleneck is rarely what you think, and a model's knowledge cutoff matters for some questions and not at all for others.
The lobster speaks Swedish now
OpenClaw — the self-hosted AI agent that actually does things — is the second video in the agent trilogy, now live in Swedish. The translation loop took an afternoon. The thing I keep thinking about is the trade I made when I installed the agent on a spare laptop next to my main one.
The lobster, the soul file, and a missing ffmpeg flag
A full-day production sprint on the OpenClaw 3-minutes video. The iterative loop with Claude, the misses that almost burned the render budget, and the moment a slide about a text file became my favorite part of the script.
Translating to a language I don't speak
Three AI models translating OpenClaw to Japanese in parallel, with back-translation as the safety net. Gemini missed a wordplay. ChatGPT was loyal but flat. The interesting part is how I'd never have caught either alone.
Gemini in 3 minutes — from script to firstcut in one day
First video built end-to-end with the new frame-overlay pipeline. ChatGPT owns the middle, HTML owns the rest, ffmpeg glues it together. Twelve slides, three iterations, no frustration.
AI Agents Are Training Us for the Azul Tournament
We built a Stockfish-style MCTS coach to help a friend prepare for a real Azul tournament — here's what worked, what didn't, and the bench numbers.
A retro day with Claude — less shipping, sharper process
Yesterday I burned hours on ChatGPT slides for the Gemini episode. Today we slowed down, talked it through, and walked away with a cleaner pipeline and a few misunderstandings cleared up.
Claude SV shipped, MCP works, and a quiet ElevenLabs feature that saved an afternoon
Day after the English Claude video: HeyGen MCP wired up, Avatar III turned out to be missing from MCP, Forced Alignment turned segment-tagging from manual to one API call.
Claude EN end-to-end, and an 8x cheaper road to automation
Built the first English Claude explainer video, then stumbled on the HeyGen MCP integration that turns a $1,150 automation budget into $145.
Finance is already here: I booked my company's first vouchers with Claude Code
The industry says AI's next leap after coding is finance. I spent an afternoon booking startup vouchers in Spiris with Claude driving the browser — and it already works.
Registering Aelg AB for real: Swedish bureaucracy with an AI co-pilot
Taking Aelg AB from 'exists on paper' to 'can actually operate' — F-skatt, VAT, a company mailbox and bookkeeping — with Claude driving the browser and getting some things wrong.
Automated Facebook Marketplace ads — photos in, sold by lunch
Claude Code took over my browser and posted four second-hand ads to Facebook Marketplace from a folder of photos. Several sold before lunch.
A Swedish dub of my own video, in one afternoon
Localizing my ChatGPT explainer into Swedish — ElevenLabs VO, HeyGen lip-sync, ffmpeg overlays, all paired with Claude Code in real time.
