Electrostatic Field Modulator for Experimental Research
Budget: $3,000 – $5,000 USD
I want to create an electrostatic field that can be modulated using AM (Amplitude Modulation), FM (Frequency Modulation), and PM (Phase Modulation) techniques. Each method of modulation should be able to operate independently as I may not need all of them operating simultaneously. This field will be controlled by a power supply whose output varies according to an audio signal. Example: a song or any audible noise I play through it. I know all the components for this project already exist. I'm just not sure what the setup should be. I would like to pay someone to develop a list of components and a proper setup for this project.
Brief explanation of setup:
Electrostatic Field Setup:
1. Electrodes: Place two conductive plates (electrodes) to create an electrostatic field between them.
Power Supply: Connect a power supply to these electrodes to generate the field.
1. Audio Signal Processing:
An audio editor like Audacity, Adobe Audition, or FL Studio to process your audio file. To extract the amplitude envelope of the audio signal, which represents the varying levels of the sound over time. (This I can purchase access to online).
2. Convert Audio Signal to Control Voltage:
A device that can convert the audio signal into a control voltage (CV). Such as a voltage-controlled amplifier (VCA) or some other modulation interface (modular synth setup).
3. Microcontroller or DAC:
An Arduino or a Digital-to-Analog Converter (DAC) to interpret the audio signal and output a corresponding voltage. The microcontroller can be programmed to vary the voltage based on the audio signal’s amplitude. (I don't expect the engineer to do the programming).
4. Power Supply Control:
A variable power supply. A power supply that is capable of being controlled by an external voltage input. This allows the power supply to vary its output voltage and current according to the audio signal.
Summary:
By modulating the power supply’s output with the audio signal, I will create an electrostatic field that varies in voltage, frequency, or phase in sync with the audible signal. This setup allows the electrostatic field to essentially “dance” to the audible input, reflecting its amplitude, frequency, and phase characteristics.
