TopSpin App
The main TopSpin page explains the Android app, Google Play testing, setup method, and what the app measures.
Open TopSpin pageWorkshop notes and technical stories
Desire3D Insights
A growing collection of practical notes behind the work: spinning top design, vibration sensing, app development, CNC machining, casting, and the physics of precision motion.
Featured insights
These pages now share the same layout and navigation. The writing is intentionally expandable, with placeholder sections ready for photos, diagrams, test data, and deeper workshop notes.
Spinning Tops: Art and Physics
A clear overview of precision tops as designed objects: material, balance, tip geometry, surface, and the appeal of calm motion.
Open spinning tops insightScience of Spinning Tops
A plain-language article about angular momentum, gyroscopic stability, precession, vibration, and sensor-based testing.
Open science insightApp Design and Testing
Development notes for the app interface, sensor handling, graphing, data export, test workflow, and future improvements.
Open app design insightMetal Casting Journey
Notes on brass, bronze, investment, burnout, vacuum casting, ingots, failures, and repeatable workshop process.
Open casting insightUseful additions for later
The structure is ready for deeper content. These are good placeholders to fill in as photos, data, and project notes become available.
CNC and repeatability
Toolpaths, workholding, offsets, surface finish, and the small corrections that improve every finished part.
Testing data
Example TopSpin charts, spin decay comparisons, and notes on how vibration changes with each design.
Workshop process
From sketching and modelling to machining, polishing, packaging, and refining based on real feedback.
