The Innovation of Schumann Signal Generation for Your Pocket
Traditional Schumann generators emit constant or only pulsed signals, which cannot capture the nuanced fluctuations of natural phenomena. The Pocket Schumann Gyrator revolutionizes this approach with a completely new circuit design that precisely replicates the natural variations and fluctuations of Schumann resonances.
Based on the T.S.T.S. generator concept, the electronics for generating the 7.83 Hz frequency and the excitation of these resonances through random numbers have been adopted, "minimized," and packaged into a housing that is with its dimensions of 10.5 x 7.5 x 2.7 cm and 205 gr weight barely larger than a pack of tissues.
Now, you can easily take this innovative Schumann resonance signal generation with you wherever you go – whether in the car (for alertness and avoiding microsleep), at work or in the home office (for enhanced performance), while traveling (for relaxation), and more. The built-in battery (18650 cell, replaceable) provides energy for at least 2 days of continuous operation. Recharging is conveniently done via a USB A to C cable and an existing USB A charger.
The range of the built-in antennas (multi-layout, inspired by the labyrinth of the Chartres Cathedral in France) is designed for the near field up to a 1-meter radius. A larger external antenna (available from March 2025) can be connected via a 3.5 mm (1/8" TRS) jack, extending this radius to up to 4 meters – ideal for use within your own four walls.
A rotary knob allows you to individually adjust the signal strength to suit your personal comfort, and the current signal strength is visually indicated by a yellow LED. A multi-color LED also provides information about the battery's charge status.

You can see from the different colors that neither the frequency nor the level is constant; instead, they alter randomly around their mean value – just as in nature, the distance and composition of the ionosphere are not constant. The ionosphere "shimmers" every second, altering its reflective properties, which in turn causes the level and frequency of the Schumann resonances to vary. If you would like to learn more about Schumann resonances, we recommend visiting our Schumann or T.S.T.S. Generator websites, where everything is described in great detail.
