What You Get With HarmonaPulse

Wide Frequency Dial

Different routines call for different settings, and a fixed-output device leaves you with one choice. One dial spans 0.01Hz to 100,000Hz, so you can pick a setting for winding down, focus, or meditation, including the Schumann range.

Two USB Cable Options

Power sources change between home and a trip. HarmonaPulse connects with a Type-B or Type-C cable, so you can plug it into a laptop, a wall adapter, or a power bank, whichever is nearby.

HarmonaPulse

Pre-Assembled Acrylic Enclosure

Loose electronics on a nightstand are awkward to handle. The circuit sits inside an acrylic enclosure that comes assembled, so you can connect the cable and set it on a nightstand or desk right away.

Sine Wave Output

Some generators produce a square wave, which is a different signal shape. A crystal oscillator and DAC chip drive HarmonaPulse's output as a sine wave, the waveform you would expect from a sine-wave generator.

Frequently Asked Questions

HarmonaPulse is a frequency generator that outputs a sine wave you select with a dial. People place it nearby during evening wind-down, focus time, or meditation as part of a personal routine.

The dial covers 0.01Hz to 100,000Hz. The low end includes the range associated with the Schumann resonance, while higher settings are there if you want to use different frequencies for focus or meditation sessions.

You can connect it to a laptop, a wall adapter, or a power bank using a Type-B or Type-C cable. A Type-B to Type-C USB power cable is included in the box.

The circuit is housed in an acrylic enclosure that arrives pre-assembled, so there is no case to build before you use it.

No. HarmonaPulse comes assembled. Connect the cable to a power source, turn the dial to your chosen frequency, and place it where you want it. A quick-start user guide is included.

You can set it on a nightstand or desk, or anywhere else in the room that suits your routine. Choose a spot within reach of your power source.

A sine wave is a smooth, repeating waveform. HarmonaPulse uses a crystal oscillator and a DAC chip to generate it, which is why it is described as a sine-wave frequency generator.

You receive one HarmonaPulse Frequency Generator in its pre-assembled acrylic enclosure, a Type-B to Type-C USB power cable, and a quick-start user guide.

HarmonaPulse runs on USB power. It connects to a laptop, wall adapter or power bank through a Type-B or Type-C cable, so this Schumann resonance generator can be used at home or while traveling.

The HarmonaPulse Schumann resonance generator comes pre-assembled in an acrylic enclosure, together with a Type-B to Type-C USB power cable and a quick-start user guide.

HarmonaPulse: A Schumann Resonance Generator for Desk and Nightstand

Anyone building a sleep, focus or meditation routine around low-frequency tones needs a source that can be tuned rather than a few fixed presets. HarmonaPulse is a Schumann resonance generator with one dial that spans 0.01Hz to 100,000Hz, so Earth's Schumann resonance and other settings are both available.

Inside, a precision crystal oscillator and DAC chip output a clean sine wave instead of a square wave. As a Schumann frequency generator, it sits on a nightstand or desk and draws power from a laptop, wall adapter or power bank.

Used as an earth resonance generator at home or while traveling, it connects with a Type-B or Type-C cable. The Schumann resonance generator arrives fully assembled in an acrylic enclosure, so it is ready once plugged in.

  • Dial range of 0.01Hz to 100,000Hz
  • Sine wave output from a DAC chip
  • USB power from common sources
