The copper pyramid

A complete build document for a grounded copper pyramid, specified to the millimetre and presented as a structured meditation object. It is not a medical device, and no field amplification has been measured.

Ratios follow the Great Pyramid's proportions. That is a geometric resemblance; it carries no implied statement about the original structure's purpose.

The array

Crystal placement

Each position is described by what the mineral actually does, and where the choice is aesthetic or symbolic that is stated plainly.

Clear quartz

North base corner

Piezoelectric: pressure on the crystal produces a measurable charge. Chosen here as the one element with an unambiguous physical function.

Rose quartz

South base corner

Placed for symbolic and aesthetic reasons. The 528 Hz association sometimes attached to it is not a property of the mineral.

Black tourmaline

East base corner

Pyroelectric and piezoelectric in principle. A small crystal has no measurable effect on room-scale electromagnetic interference.

Citrine

West base corner

Quartz family, included for symmetry and colour balance across the four corners.

Selenite

Apex, suspended

Soft gypsum, decorative at the apex. Suspend 5–10 cm below the copper apex with non-conductive line.

Assembly

Six steps

  1. 01

    Ground the structure

    Drive a 1.2 m copper rod into moist earth and bond it to the pyramid base with 6 AWG copper wire. Indoors, use a copper grounding mat on a standard earth ground.

  2. 02

    Orient to north

    Align one face of the pyramid with true north using a compass. Mark the base corners before cutting tube so the frame stays square.

  3. 03

    Set the water basin

    Place a copper or earthen vessel of water beside the pyramid. Cover it when not in use; standing water indoors is a splash and humidity risk.

  4. 04

    Build the crystal array

    Place one crystal at each base corner. Suspend the apex crystal from the top junction. Keep the array away from foot traffic and children.

  5. 05

    Choose the seat

    The seat point is one-third of the height above the base. Sit facing north, with the apex above and slightly behind your eyeline.

  6. 06

    Run a session

    Use the timer below: 5 s in, 5 s hold, 5 s out, for six to twelve minutes. Keep the room quiet and the temperature steady.

Sit at one-third of the pyramid height. Breathe in 5 s, hold 5 s, out 5 s. At least six minutes of smooth breathing is a common starting point in the coherence literature.

Read this before building

  • This is a meditation object and a geometry study. It is not a medical device, and no health benefit has been demonstrated for it.
  • Do not use it as a substitute for medical care, and do not stop or change treatment on the basis of anything on this site.
  • Cutting copper tube produces sharp edges and metal dust. Wear eye and hand protection, and work in a ventilated space.
  • The device is unpowered and passive. Any effects you notice are subjective and should be read as such.
