Small tools that fix specific annoyances. macOS menu-bar utilities, self-hosted services and research tooling. Public, deliberately small, and built because the thing didn't quite exist yet.
Swift / AppKit / IOKit / Menu bar
The honest wattage number, in your menu bar.
Most chargers report what they are rated for. macOS repeats that number. Nobody tells you what is actually crossing the cable.
Python / Swift / yt-dlp / ffmpeg / SQLite
YouTube channels as a podcast feed on your own Wi-Fi.
Podcast clients only understand one thing: an RSS feed with enclosure links. PodcastSync makes a YouTube channel look like exactly that, served from your own machine.
Swift / AppKit / DDC/CI / Sparkle / CI
Display control for current macOS, including the brightness macOS hides.
LumaControl started as a fork of MonitorControl and became its own project, with a focus on current macOS releases, a native-feeling interface, and display-control ideas upstream had not taken on.
JavaScript / Zotero 9+ / Python (build) / Keychain
AI summaries for Zotero that show you the payload before they send it.
The default shape of an AI feature is a button that quietly ships your document to a server. The default shape of a research workflow is a folder of unpublished drafts and embargoed data.
JavaScript / CSS 3D / Web Audio / No build step
A $3,500 split-flap board, emulated in a browser tab.
Real split-flap boards cost thousands. FlipOff turns any television or monitor into one, and it is a single index.html with no build step and no dependencies.
Swift / SwiftUI / CryptoKit / SwiftPM
What's eating your disk, without the ceremony.
A minimal native SwiftUI app that answers one question: what is taking up the space? Expandable size-sorted tree, totals grouped by file extension, and a duplicate finder — all readable end to end and yours to hack on.
C# / JavaScript / Python
METAR Viewer is a Windows application that translates raw METAR Data into a more "human-friendly" format. FOR FLIGHT SIM ONLY
METAR Viewer fetches and decodes aviation weather reports (METARs) into plain English. Search by ICAO code, IATA code, airport name, or even a common misspelling, and get wind, visibility, cloud layers, temperature, altimeter, present weather, and flight category back in a readable form. Simulation and hobby use only; not for real-world aviation or weather decisions.

Note 01 / 2 Sept 2026
Finding duplicates without hashing your whole diskThe naive way to find duplicate files is to hash everything and group by digest. It is correct, it is simple, and on a disk with a million files it will make you wait a very long time to learn that most of your files are not duplicates.

Your 140 W charger probably isn't delivering 140 WPlug in a 140 W charger. Open System Information. It says 140 W. Everything agrees, nothing is lying, and yet the number describes the adapter's claim about itself — not what is arriving at the battery.

Modelling a split-flap display in the browserA real split-flap display has no pixels. It has a stack of physical cards on a spindle, and a cell can only ever show the card currently at the front. To get from A to B, the mechanism does not fade or slide — it flips forward through every card in between.

The brightness range macOS won't show youThe brightness slider in macOS stops at 100%. On an XDR panel, 100% is not the ceiling — it is a convention. There is more light available, and macOS will let you reach it if you ask through the right private interface.

AI summaries that ask permission firstThe default shape of an AI feature is a button that silently ships your document to a server. The default shape of a research workflow is a folder full of unpublished drafts, embargoed data, and things covered by an ethics approval.

Turning YouTube channels into a private podcast feedPodcast apps are the best audio player on your phone, and they will only talk to one thing: an RSS feed with enclosure links. That is the whole interface. If you can produce a valid feed and serve MP3s, you have a podcast — regardless of where the audio actually came from.
