User:Eleni/Biodata Sonification

Holding myself accountable ✨

This is the beginning of a new project; I am creating my own Biodata Sonification Device using this tutorial, while also documenting my process on here! I know next to nothing about MIDI and Galvanic Conductance, but we are experimenting (fucking around and finding out)

Check out some example results and get excited like me! here & here

Latest Update:

08/10 - Parts have been purchased 🤞🤞

List of Tools

From what I've gathered from the tutorial I need:

• 3.5mm jack
• Blue (?) Capacitor 4700pf
• Resistor (3.9K)
• 555 Timer IC (8pin)
• 5 LEDs (red, orange, green, blue, white)
• 10 Ohm Resistor
• 11 Jumper Wires
• Solderless Breadboard
• CR2032 Button Battery 3 volts
• Adafruit Feather ESP32
• microUSB Cable

What is Biodata Sonification??

Sonification is the use of non-speech audio to convey information or perceptualize data. Auditory perception has advantages in temporal, spatial, amplitude, and frequency resolution that open possibilities as an alternative or complement to visualization techniques.

Biodata Sonification (or Bio-sonification) is a process to translate complex real-time sensor data into musical notes and controls, exploring auditory sensory modality to provide insights into invisible phenomenon.

“Bio-sonification,” basically means using technology to turn the bio-rhythms of living organisms into sound. -

Some extra info for components

Capacitor

(In Greek: Πυκνωτής) In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser,[1] a term still encountered in a few compound names, such as the condenser microphone. It is a passive electronic component with two terminals.

The utility of a capacitor depends on its capacitance. While some capacitance exists between any two electrical conductors in proximity in a circuit, a capacitor is a component designed specifically to add capacitance to some part of the circuit.

Resistor

(In Greek: Αντιστάτης) The resistor is a passive electrical component that creates resistance in the flow of electric current. In almost all electrical networks and electronic circuits they can be found. The resistance is measured in ohms (Ω). An ohm is the resistance that occurs when a current of one ampere (A) passes through a resistor with a one volt (V) drop across its terminals. The current is proportional to the voltage across the terminal ends. This ratio is represented by Ohm’s law:

R = V/I

The resistance value and tolerance are indicated with several colored bands around the component body. This marking technique of electronic components was already developed in the 1920s. Printing technology was still not far developed, what made printed numerical codes too difficult on small components. Nowadays, the color code is still used for most axial resistors up to one watt. In the figure above, an example is shown with four color bands. In this example the two first bands determine the significant digits of the resistance value, the third band is the multiplying factor and the fourth band gives the tolerance. Each color represents a different number and can be looked up in a resistor color code chart or using a resistor color code calculator.

For this project we need:

• 

  Orange / White / Red

• 

  Brown / Black / Brown Resistor

555 Timer

The 555 timer IC is an integrated circuit used in a variety of timer, delay, pulse generation, and oscillator applications.
