This is a small signal generator that outputs a sine wave from 0.1Hz to 30000Hz, defaulting to the 7.83Hz Schumann resonance. It runs on 5V over Micro USB, draws under 1W, and has a bare circuit board of roughly 15 by 10 cm. It suits people curious about frequency and meditation soundscapes who want an adjustable low-frequency source. It is a signal generator, not a medical device, and no clinical evidence supports the healing claims; treat it as an experimenter's tool rather than a therapy product.

This Schumann resonance generator is a low-frequency pulse audio device. It outputs 7.83Hz by default, the frequency of the Earth's Schumann resonance. The frequency can be adjusted from 0.1Hz to 30000Hz. It is meant for use as a sound frequency source for relaxation, meditation and yoga.
To set a frequency, enter the number on the keypad and press OK. For example, press 7, then the decimal point, then 8 and 3, then OK to set 7.83Hz. The device powers on at 7.83Hz each time.
To use it, connect the included USB cable to the circuit board. Plug the other end into a power bank, USB charging head or other USB powered device. To hear the signal, plug the audio jack in fully and connect it to an amplifier, or listen with headphones.
