Description: This scientific diagram shows a spark-gap dipole transmitter sending curved radio waves to a loop receiver that sparks in turn, above c = λ · f, on a deep dark background. Between 1886 and 1888, Heinrich Hertz produced and detected electromagnetic waves with a spark-gap transmitter, confirming Maxwell's theory. The unit of frequency, the hertz, is named after him. Made for electricians, electrical engineers and anyone powered by curiosity, it suits a workshop, lab, study or office.

Description: There is a frequency the modern world forgot. 432Hz — the natural tuning of the universe. The frequency of the cosmos, of ancient instruments, of the human heart in coherence. Before the 1953 standardization to 440Hz, this was how music was tuned. This was how sound healed. This design channels that forgotten frequency into wearable sacred art — Metatron's Cube anchoring the four corners, esoteric sigils woven into the plasma field, sacred geometry radiating outward from a single point of light. Every symbol here is a key. Every line is a map back to something your cells already know. For the frequency seeker. The sound healer. Spread the good vibes.

Description: Rendered on a deep dark background, this artwork presents four sine harmonics stacked above a square wave rebuilt from their sum, with the series f(x) = 4/π Σ sin(nx)/n for n = 1, 3, 5, 7. In 1822 Joseph Fourier showed that any periodic signal can be written as a sum of sines and cosines. Fourier analysis now underpins audio, image compression, telecommunications and much of modern engineering. Made for engineers, inventors and anyone who loves to understand how things work, it suits a workshop, office or study.
