Hello there! I'm Arthur Soares

I'm a Brazilian from Belém, now living in Berlin and building tech products—both digital and physical—at HOLOPLOT. I’m also a photographer, a tech tinkerer, and someone with more hobbies than time.

This site is my corner of the internet — part archive, part playground. You’ll find personal updates, photo essays, deep dives into whatever’s caught my attention, and the occasional rant or experiment.

If something here clicks with you, feel free to subscribe below to get updates or follow via RSS. And if you ever want to talk, my inbox is open. 👋

Uncoded: Fixing 6-bit encoding for Leica

One small Mac app to fix the 6-bit lens metadata your Leica M wrote for third-party glass — Zeiss, Voigtländer, and anything else wearing a borrowed code.

A Simple Photo Gallery

I pulled the photo gallery out of this website and turned it into something you can fork: drop photos in a folder, push, and GitHub gives you a photo site for free.

It feels like a different team. What I learned migrating my household agent from Claude to GPT-5.4

On April 4th Anthropic cut OpenClaw off from Claude Pro/Max. I had 72 hours to move a 14-agent household assistant to GPT-5.4. It was not a config change. It was a personality migration.

New Section: Photos and AlbumsI finally gave my photos and albums a proper home on the site

Dispatch vertical poster
AdHoc Studio

Dispatch (2025)

A playable-TV superhero workplace comedy that sharpens the Walking Dead-era Telltale formula: splendid art, dry humor, and voice work from Aaron Paul and Jeffrey Wright. Mecha Man loses the mech and becomes a behind-the-desk hero dispatcher across eight episodes.
João Gilberto (1973)
João Gilberto

João Gilberto (1973)

If I could pick only one João record, this would be it: voice, guitar, and the faintest percussion from Sonny Carr. Old sambas, newer songs, and João’s own, all stripped to their quiet, impossible center.
The Audacity (2026)
Jonathan Glatzer

The Audacity (2026)

Silicon Valley satire with its ethical rot left proudly above ground. The creator was a writer/producer of Succession and Better Call Saul. The series has its flaws, but it is a clear recommendation.
Pentiment
Obsidian

Pentiment

A 16th-century murder mystery where you play as Andreas Maler, an artist/scribe in Oberbayern. Beautiful art and pace.
