A set of free interactive tools for exploring Sacred Geometry — the language of pattern, ratio, and form that runs through Egyptian pyramids, Slim Spurling’s Tensor Rings, Pythagorean philosophy, and modern mathematical physics. All four tools run in your browser. No data is sent to any server.
📖 What’s inside — (1) Cubit Converter — convert any length to all 4 Cubit units. (2) Phi (φ) Golden Ratio Calculator — multiply, divide, square any number against φ. (3) Lecher Antenna Frequency Estimator — predict resonant frequency from wire length. (4) Platonic Solids Visualizer — 5 perfectly regular 3D shapes with vertex / edge / face data.
Cubit Converter
Enter any length in cm, mm, or inches — convert to all 4 Cubit units used by Slim Spurling.
Result = how many full Cubit units fit in your length. A precise Tensor Ring's circumference is an integer multiple of one Cubit.
Phi (φ) Golden Ratio Calculator
Phi = 1.6180339887... appears in nature (sunflowers, nautilus shells), art (Da Vinci, Parthenon), and Sacred Geometry (Sri Yantra, Vesica Piscis).
Fibonacci sequence: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233 ... ratios approach φ as N grows.
Lecher Antenna Frequency Estimator
Estimate resonant frequency from wire length. f = c / λ where c = speed of light. Reference only — verify Tensor Rings with a real Lecher Antenna.
Sacred Cubit ring (45 cm) → ~144 MHz · Lost Cubit (90 cm) → ~177 MHz · Slim 188 (~48 cm) → ~188 MHz
Platonic Solids Visualizer
The 5 perfectly regular 3D shapes Plato linked to the classical elements. Click each shape for vertex / edge / face counts and dihedral angle.
How These Tools Connect
Cubit + Lecher + Phi + Platonic Solids are not four random tools — they’re four windows into the same body of pattern knowledge that civilizations have used for thousands of years to design temples, instruments, music, art, and tools that “feel right”.
- The Cubit is a length unit Egyptian pyramid builders, Greek temple architects, and Slim Spurling all used because it produces ratios that resonate cleanly with light, sound, and human perception.
- Phi (φ) is the ratio that makes Cubit-based design “feel right” — it appears in flowers, shells, our own bodies, and the Parthenon.
- The Lecher Antenna measures the resonant frequency of an object — the tool Slim Spurling used to verify that his Tensor Rings actually produced a stable scalar field.
- The 5 Platonic Solids are the only perfectly regular 3D shapes possible. Plato linked each to one of the classical elements (fire, earth, air, water, aether). Modern Sacred Geometry uses them as building blocks for crystal grids and meditation focus.
Tool Notes
Cubit Converter
Enter any length in cm, mm, or inches. The calculator divides by each Cubit value to show how many full units fit. A precise Tensor Ring’s circumference is an integer multiple of one Cubit — for example, a Sacred Cubit ring’s circumference is exactly N × 1.7718 inches.
Phi (φ) Calculator
φ = (1 + √5) / 2 = 1.6180339887… Enter any number and see N × φ, N ÷ φ, N², plus the closest Fibonacci number. Adjacent Fibonacci ratios approach φ as N grows: 13/8 = 1.625, 21/13 = 1.615, 34/21 = 1.619, 55/34 = 1.617…
Lecher Antenna Frequency
Estimate resonant frequency of a closed-loop conductor: f = c / λ where c is the speed of light (≈ 300,000 km/s) and λ is the wavelength. Three modes:
- Half-wave (default): λ = 2 × wire length — most common dipole assumption
- Full-wave: λ = wire length — closed loop running one full wavelength
- Quarter-wave: λ = 4 × wire length — antenna shorted at one end
This estimator is a reference tool only. Real Tensor Ring frequency must be verified with an actual Lecher Antenna because the scalar field interaction is more complex than simple dipole physics.
Platonic Solids Visualizer
Click each solid to see its V (vertices) · E (edges) · F (faces), classical element, face shape, dihedral angle, and symmetry order. Use this for crystal grid design, meditation visualization, or as a reference for sacred geometry art.
Honest Disclaimer
📖 What these tools are — and what they aren’t. They are educational reference calculators for exploring Sacred Geometry pattern relationships. They are not medical advice, not engineering specifications for actual electromagnetic devices, and the Lecher-Antenna estimator is reference math (real Tensor Rings must be verified with physical testing). Scalar wave physics remains in the fringe-science domain — no peer-reviewed mainstream physics studies confirm scalar wave existence as Tesla and Spurling described it.
