 | Tools for my own machine. Linux utilities, firmware, libraries, and a lot of things written twice. I learn a system by building it, so some of these exist only because I wanted to understand something. Read the code before you run it. This page is a summary — the project site has every repo, searchable. |
If you open one thing, open one of these. The rest is grouped below.
| Project | What it is | |
|---|---|---|
| Scala libraries | worxbend/worxbend → libs/commons/pretty-printo | Pretty-prints any Scala 3 value. Mark a field @Excluded or @Redacted and it prints the declared type without ever reading the value — the secret never enters the output path. |
worxbend/worxbend → libs/commons/reveal | Same idea, derives PrettyPrintable, all resolved at compile time. Zero reflection, zero per-call cost, zero runtime deps. Enums, sealed traits, opaque types. | |
| OBS & streaming | worxbend/obs-stats | btop for OBS. CPU, frame pacing, encoder health, scenes, audio — live, in a terminal. |
| worxbend/obsctl · worxbend/obsctl-rs | Script OBS from the shell. Written twice: Crystal, then Rust. | |
| Air quality | worxbend/airgradient-desktop · ·-android · ·-cli · ·-papr | One sensor, read five ways: GTK, Android, CLI, e-paper, GNOME applet. LAN only, no cloud account. |
| Linux setup | worxbend/fluxion.cr · w0rxbend/system-bootstrap | Wiped disk to working dev machine, driven from Git. |
| Hardware | w0rxbend/spycam + w0rxbend/instachron | Two halves of one link. ESP32-CAM pushes JPEG frames over a raw TCP socket; a Go server catches them. |
Everything that runs while the stream is live. Most of it drives OBS over obs-websocket.
| Project | What it does | Built with |
|---|---|---|
| worxbend/scenedeck | Desktop window for Linux: switch scenes, toggle sources, start and stop the stream. Shipped on Snapcraft. | Rust, GTK4 |
| worxbend/obs-stats | btop for OBS health, live in a terminal. | Rust, Ratatui |
| worxbend/obsctl | CLI plus TUI for scenes, audio and profiles. A daemon keeps the socket warm so commands are instant. | Crystal |
| worxbend/obsctl-rs | Same controller, rewritten in Rust. Keyboard-driven, full screen. | Rust, Ratatui |
| worxbend/multistream-manager | Fill one form, press Start Streaming once, go live on Twitch and YouTube together. | Rust |
| worxbend/twi | Twitch chat over IRC in a terminal. Multiple channels, 13 themes. | Go |
| worxbend/yc | YouTube live chat in a terminal, with the daily API quota on screen. 58 themes. | Go |
| worxbend/streaming-tools-site | Interactive map of how these tools wire into OBS, Twitch and YouTube. obs.worxbend.com | JavaScript, PixiJS |
| w0rxbend/obs-effects | Animated transparent overlays, dropped into OBS as browser sources. obs-effects.worxbend.com | TypeScript, PixiJS 8 |
| w0rxbend/twitch-voxer | Reads chat aloud. Detects Ukrainian or English, pins one voice per chatter. | Python |
| w0rxbend/twitch-vizer | Alerts for follows, subs, cheers and raids, off Twitch EventSub. | Python, TypeScript |
| w0rxbend/twitch-musicplayer | Go service serves the library, browser front end plays it and draws the visualiser. | Go, TypeScript |
| w0rxbend/chat-brawl | Type in chat, spawn into an on-screen fighting arena. | TypeScript, PixiJS |
pretty-printo and reveal live in the worxbend monorepo, not in
their own repos. Mill build, reusable pieces under libs/.
| Project | What it does | Built with |
|---|---|---|
libs/commons/pretty-printo | Configurable string rendering for any value. @Excluded and @Redacted fields are described from their declared type, so the printer never touches the value — which is what makes redaction and null safe. | Scala 3, Magnolia |
libs/commons/reveal | The successor, derived by macro. Omissions, redactions and type spellings are all decided during expansion. No reflection, no runtime deps. Enums, sealed families, opaque types. | Scala 3 macros |
| w0rxbend/scalacv | Scala 3 API over OpenCV 4.13. Typed pipeline that frees native memory exactly once. Docs | Scala 3, OpenCV |
| worxbend/gitea-scala-client | Typed Gitea client, verified against the OpenAPI contract. Site | Scala 3, ZIO 2 |
| worxbend/codeberg4s | Codeberg and Forgejo client returning plain Future. No effect system dragged into your build. | Scala 3, sttp |
| w0rxbend/shield | Self-hostable auth server, wire-compatible with SuperTokens clients. | Scala 3, ZIO |
| w0rxbend/compression-flix | Lichess clock and move compression ported to Flix, byte-for-byte. One differing bit would invalidate every stored game. | Flix |
| w0rxbend/scalachess-flix | Lichess chess rules in Flix, checked against the upstream fixtures. Not a drop-in replacement. | Flix |
| w0rxbend/data-engineering | Kafka, Kafka Connect and Flink sandbox, with a custom partitioner for the S3 sink. | Scala, Kafka |
| worxbend/playground | One event-streaming service, three web frameworks, side by side. | Scala 3, Kafka |
| worxbend/worxbend | The monorepo: small Scala apps, the libraries above, deploy recipes, notes. | Scala, Mill |
Wiped disk to working dev machine, no manual steps. The same tool shows up four times in four languages. That is not accidental — rebuilding something you already understand is how you learn a language, because the problem stops being the problem.
| Project | What it does | Built with |
|---|---|---|
| worxbend/fluxion.cr | One YAML file: packages, Flatpaks, dotfiles, fonts, binaries. Diffs the plan before it touches anything. CLI or TUI. Site | Crystal |
| w0rxbend/system-bootstrap | My real setup: Fedora, Arch and openSUSE. Packages, binaries, dotfiles, Nerd Fonts, terminals, Neovim, GNOME/COSMIC/Sway. | Shell, Lua |
| worxbend/fluxion | The original, on the JVM. Records what it installed so the second run skips finished work. Site | Java |
| worxbend/binstaller | Same prebuilt binaries on every machine from one profile. SHA-256 checked, lock file written. Site | Scala 3, GraalVM |
| worxbend/nerd-fonts-installer | Nerd Fonts from one config file, with an interactive picker. Site | Go |
| worxbend/dotbot-go · worxbend/dotbot-scala | Dotbot rewritten twice. The Scala one compiles to a static binary, so the target box needs no JVM. | Go · Scala 3 |
| w0rxbend/infrastruct | An ARM homelab as files in Git: inventory, Ansible, K3s with Flux CD, Docker stacks, encrypted secrets. | Python, Ansible |
| w0rxbend/ops-dashboard | Watches that homelab. Exporters, VictoriaMetrics, Grafana, uptime checks, one browser dashboard. | TypeScript, SolidJS |
Firmware on small Wi-Fi boards, usually shipped with the server on the other end of the socket. Raw TCP, no broker, no cloud.
spycam is the camera half: ESP32-CAM firmware that captures JPEGs and
pushes the newest one over a long-lived raw TCP socket, dropping stale frames and reconnecting on its own.
instachron is the server half: a Go service that listens on that
socket, stores frames, and republishes them over HTTP with restreaming, optional detection and upscaling, and
a timelapse recorder. spycam-s3 is the camera half rebuilt for
ESP32-S3, stamping a camera ID into every frame so several boards feed one server.
CO₂, PM2.5, temperature and humidity off an open-source indoor monitor. Every client below reads the device over LAN. No cloud account, no vendor app.
| Project | What it does | Built with |
|---|---|---|
| worxbend/airgradient-desktop | Linux desktop window, live readings, monitor discovered on the network. | Rust, GTK4 |
| worxbend/airgradient-android | Native Android app. Dashboard plus notifications past a severity threshold. | Kotlin, Compose |
| worxbend/airgradient-cli | Reads the desktop app's config, fetches once, prints compact. | Rust |
| worxbend/airgradient-papr | E-paper firmware. Portable readout with weather and forecast. | C++, ESP32 |
| worxbend/airgradient-gnome-extension | One icon in the GNOME top bar, coloured by air quality, gauges in the popup. | JavaScript |
| worxbend/airgradient-observability | Self-hosted metrics: collector scrapes the sensor into VictoriaMetrics, Grafana on top. | TypeScript, Go |
| worxbend/tv-dashboard | Always-on TV dashboard: air quality, weather, indoor climate, agenda, system status. | TypeScript, SolidJS |
| w0rxbend/neoncore | Addressable LED panel as an air-quality indicator. Readable across the room, no legend needed. | C++, ESP32 |
| Project | What it does | Built with |
|---|---|---|
| worxbend/frostfire | ESP32 across a PC power-button header. Remote power-on. Fixed-length pulses, relay off at boot, token required. | C++ |
| worxbend/frostfire-backend | The guarded service in front of that relay. Every request hits a safety policy before it reaches hardware. | Python, FastAPI |
| w0rxbend/led-matrix-controller | ESP8266 driving an 8x8 panel. Binary command protocol over TCP, falls back to its own AP when unconfigured. | C++ |
| w0rxbend/echo | Webhook to LED panel. Post an event, rules pick an animation, echo pushes it over TCP and reconnects itself. | Go |
No API stability, no release cadence, no support. Issues and small PRs welcome — Linux usability, packaging, docs, clear bugs. Anything that changes a project's direction will probably get a no.
