• Ukulele Tuner

  A browser-based tuner for standard GCEA ukulele tuning. Uses your microphone to detect pitch in real time and shows how many cents flat or sharp each string is. Click a peg or string on the ukulele graphic to lock the tuner to it. Audio never leaves your device.

• 3D Models

  Parametric 3D-printable parts written in OpenSCAD — replacement toy parts, workshop blast gates, a laptop stand, and terrain models. Each one has an interactive viewer you can spin around, and a Customize button that re-renders the part in your browser with your own dimensions.

• Chess Tools

  Interactive chessboards: the Knight's Move Calculator (minimum knight moves between any two squares), plus Bishop's Agility and Queen's Agility maps showing how many squares each piece can reach from every square.

• TempoStatusBar

  A macOS menu bar app that shows how many days have passed since your last Jira Tempo worklog submission. Color-coded status (green within your threshold, orange one day over, red beyond that), a configurable warning threshold, and hourly auto-refresh via the Tempo REST API.

• Popular Free Audiobooks

  The most-downloaded public-domain books on Project Gutenberg that also exist as free LibriVox audiobooks — sorted by popularity so you can find titles you actually recognize.
