VAEMI Electromagnetic Field Microphone Lets You Listen To The Invisible
Volt Age Electronic Musical Instruments (VAEMI) shared this video demo of the El-Ma Ørsted V2, a new device that lets you ‘listen’ to electromagnetic fields.
The El-Ma Ørsted can detect radio waves, electromagnetic fields emitted by electronic devices, and environmental electromagnetic interactions. Its most fundamental difference from a conventional radio is its ability to capture a wide frequency range that covers the entire electromagnetic activity of its surroundings. This characteristic makes El-Ma Ørsted a unique instrument for experimental music, sound art, and environmental sound exploration.
The device’s unusual name is based on “El-Ma”, an abbreviation of “electro magnetic”, and the last name of Hans Christian Ørsted, a physicist and chemist known for his discoveries in the field of electromagnetism.
El-Ma Ørsted V2 – Evolution in Design
El-Ma Ørsted V2 preserves the electronic infrastructure and sonic character of the previous version, but has been redesigned in a more compact form. The new model features a rear battery cover that allows the 9V battery to be inserted and removed quickly and easily.
Electronically, El-Ma Ørsted V2 delivers the same sensing sensitivity and sound character as the previous version, using the same components and coils.
Technical Specifications:
- Bandwidth: up to 140 kHz
- Components: Carefully selected, RoHS-compliant electronic components
