Schumann Resonance Generator With Crystal Oscillator: 0.01 Hz to 100 kHz Sine Wave
Experience pure, stable low‑frequency sine waves without noise or drift. This generator delivers clean analog sine output from 0.01 Hz up to 100,000 Hz, backed by crystal‑controlled stability and a high‑precision DAC for reliable experimentation. The default preset is 7.83 Hz Schumann resonance and is set at power‑on, ready to use.
No setup required — just power it on and the default frequency is active. The RES button returns you to 7.83 Hz from any custom setting.
Wide frequency range for diverse applications
- 0.01 Hz – 1 Hz: Ultra‑low frequency experiments
- 1 Hz – 20 Hz: Resonance and meditation applications
- 20 Hz – 20 kHz: Audio range for speaker output
- 20 kHz – 100 kHz: Higher frequency testing
Precision, stability, and waveform
- Frequency range: 0.01 Hz – 100,000 Hz
- Output waveform: Pure analog sine wave
- Frequency reference: Low temperature drift crystal oscillator
- DAC: High‑precision dedicated chip
Display, input, and user experience
- Display: LCD1602 with backlight for clear readouts
- Input: Numeric keypad for direct frequency entry
- Example entry: 7, decimal point, 8, 3, OK — confirms 7.83 Hz
Backlight toggle keeps the display readable in any lighting conditions.
