Perspectives and Experiences: Looking at Miniatures

Artists,Reference — Ali Momeni @ 6:00 pm

IN CLASS: Feb. 8, 2012, sensors to actuators

Electronics,In-Class,Max — Ali Momeni @ 9:05 pm

We continue our work with sensing circuits (using photoresistors) and actuators (LEDs, incandescent light bulbs, motors, and servos).  Connect the necessary components on a bread-board to do the following:

  • One photo resistor controlling the rotation of a servo motor
  • One photo resistor controlling the brightness of an LED
  • One photo resistor controlling the brightness of an incandescent light bulb
  • One photo resistor controlling the speed of a DC motor

Once the circuitry and the Max patch for the above set of mappings is complete, the begin integrating elements from your collection of very-small-things, by attaching some of your collected items to your motors and servos, and lighting other collected items with LEDs and light bulbs

Simple circuit for connecting a variable resistance sensor to a micro-controller (with details regarding our favorite microcontroller the Arduino-compatible Teensy):

Controlling DC Motors/Lights: Microcontroller to MOSFET

Electronics,Reference — Ali Momeni @ 6:27 pm

The above diagram shows how to use a microcontoller (like our Arduino-compatible Teeny board) and a MOSFET to turn on/off a DC motor or a light.

In the above diagram:

  • “Load”: your light or actuator (including motors, solenoids) and its two leads
  • “Load Power +12″: the positive terminal of your power supply; note that this voltage can be different than +12V” as long its within the MOSFET’s specifications
  • “MOSFET”: the three leads are labeled [G]ate, [D]rain and [S]ource; refer to the MOSFET’s datasheet to assure which pin is which
  • Grounds: the MOSFET’s [S]ource pin connects to the ground of the power supply; the microcontroller’s ground pin should also be connected to the ground of the power supply
  • “Control +5V”: this connection is to one of the digital outputs pins of the microcontroller (either Digital I/O or PWM)

The big questions/the big map

  • Why is the notion of uncanny important to us as artists?
  • Why read Freud?
Topics from the article:
  • language
  • Hoffman’s sand man
  • the eye and the male organ (p. 8, left, bottom)
  • automata, the uncanny valley (p. 7 left)
  • the double (p. 10, right, middle)
  • repetition: groundhog day (p. 11, left, top)
  • repetition: coincidence  (p. 11, left, bottom)
  • repetition: neurosis (p. 11, right bottom)
  • the evil eye (pp. 12, right, middle)
  • the omnipotence of thought
  • epilepsy and disease (p. 14, right, bottom)
  • imagination meeting reality (p. 15, left)
  • surmounted feelings (p. 15, left and p. 17 left)
