Software for sports broadcast production — and a few things built just for fun.
Stream management, clipping, and playback tools for live sports production.
Manages simultaneous SRT video restreams for tennis tournaments with up to 6 court cameras. Built with FFmpeg and NVIDIA NVENC hardware encoding, featuring a web interface, per-court status, FFmpeg logs, and Google Chat webhook notifications.
PHP dashboard for managing SRT video streams from AIDA cameras, with per-camera streaming control, real-time status polling, and customizable camera configuration.
Browser-based HLS highlight clipper that needs no server uploads or software install, powered by FFmpeg.wasm. Keyboard shortcuts (I/O keys), a clip queue, frame-accurate adjustment, and stream-copy export.
Browser-based HLS video player built for official review, with frame-accurate playback controls and support for .m3u8 stream URLs.
Browser-based dashboard for viewing multiple live streams simultaneously, built for keeping an eye on several feeds at once during a broadcast.
Web app for managing and scheduling video ads in vMix, with ad library configuration and weighted playlist generation by duration. Network-accessible for multi-operator use.
Electron desktop app for building and managing vMix playlists — a native counterpart to the browser-based vMix Ad Manager, focused on general playlist control rather than ad scheduling.
Browser-based replay tagging app for vMix, built with HTML, JavaScript, and Bootstrap. Ships with sport-specific configurable button presets for basketball, lacrosse, and a general default.
OBS Studio audio filter plugin providing a full gain matrix — mix any input channel into any output channel at its own dB gain. Useful for muting comms feeds, downmixing, or rerouting channels. Originally created by Andersama; updated and maintained for OBS Studio 32.
Interfaces and firmware for cameras, mixers, scoreboards, and other production hardware.
Web-based controller for a Bolin EXU-230NX PTZ camera: pan/tilt/zoom/focus controls, 16 customizable presets with thumbnails, drag-and-drop reordering, SRT toggling, and a preset-only view mode.
Electron GUI that connects a Behringer XR18 mixer and a Dante Virtual Soundcard over NDI, enabling full-duplex comms over a standard network.
MicroPython firmware for an ESP32-S3-ETH board that reads live scoreboard data from a Daktronics AllSport 5000 controller and serves it as JSON over Ethernet. Monitors RTD serial packets at 19200 baud and supports baseball, basketball, volleyball, football, and hockey/lacrosse.
Browser-based LUFS audio level meter for microphone monitoring, implementing ITU-R BS.1770-4 K-weighting. Features a 3-second integrated loudness window, 30-second history graph, color-coded display, and device selection.
Parsing, fixing, and routing stats feeds between the systems that need them.
Parses live stats XMLs and generates data feeds for broadcast graphics systems.
Internal tool — no public link
Corrects team codes in NCAA game XML files, getting broadcast graphics systems working with stats feeds that have mismatched or missing team codes.
PowerShell script for stat file monitoring, watching StatCrew, NCAA LiveStats, or Presto Stats input and outputting JSON files for vMix datasource ingestion.
Audio, photo, and web platforms for sports organizations.
Soundboard app for game-day audio operators, with sound effect and music banks, keyboard shortcuts, crossfades, private preview, and fullscreen mode. Available for Windows and Mac.
Photo management platform for sports organizations: automated tagging and crediting, photographer uploads, staff tagging using team rosters, and IPTC/XMP metadata embedding.

100% local, client-side photo tagging tool: open a folder of JPEGs in the browser and tag who's in each photo, with tags written straight into IPTC/XMP metadata. No server, database, or upload — nothing leaves the device.
Searchable directory of 1,359 college athletics websites across NCAA Division I, II, III, and NAIA, filterable by state, division, or conference. A Chrome extension is also available.
Self-hosted bookmark dashboard with a dark Tailwind UI: SQLite-backed, with an admin interface for organizing links into categories under one or more page sets. Supports public and restricted page sets (trusted IP range and/or Shibboleth login), drag-to-reorder, and live search.
A couple of things built for the house rather than the broadcast booth.
Self-hosted web dashboard for a recteq pellet smoker, connecting directly over the local Tuya protocol with no cloud dependency. Shows live grill, target, and probe temperatures, a 6-hour history chart, and connection status in a dark-themed UI.
Self-hosted, multi-user TV show tracker — a lightweight TV Time clone. Vanilla JS PWA frontend backed by a PHP + SQLite API using TMDB for show data, with Google sign-in behind an admin-managed allowlist, per-episode/season watched tracking, and an infinite-scroll episode calendar.
Lightweight order pad for cookouts and group meals: set a menu, share a no-login link for guests to submit orders, and watch live totals by category and option. Single PHP backend on JSON files, Google Sign-In gated access, multi-user accounts, and client-side QR codes for the guest and view-only links.
