Ferro
Processing
With processing and Minim, I laod mp3s and parse the sounds to send via Serial to Arduino:
Arduino
I used an Uno to Control a continuous rotation servo with incoming direction cues from Processing:
Other Materials
Worked
- 4 oz ferro fluid
- 2 magnets about 1.5 inches in diameter
- 1k and 220k resistors
- breadboard
- jumper wires
- isopropyl 70%
- scalpels & blades
- steel ruler
- silicon stretch top for ferrofluid dish
- hot glue & sticks
- arcade spst momentary buttons
- 2 5k potentiometers & dials
- Headphones
- continuous servo 360
Tried, did not work out
- rainx as a hydrophylic to prevent ferrofluid stains
- isopropyl 91% alcohol
- 12V 700N electromagnet
- aluminum plate (would have used as heat sink for large emagnets)
- 8266 board for wifi communication
- 3.3v voltage regulators (for logic level power on the 8266)
- 25N 9V electromagnet (too weak to pull fluid)
- nema17 stepper motor with detachable wires 12v
- a4988 stepper motor driver
- sg90 9g mini servo (too loud)
