Hello and welcome to 3D Media Studio II (Animated Theater).

Links to relevant resources for the course as well as student contributions and discussions will be posted on this blog.

Please begin by viewing the syllabus page.

Here are some pictures of the final projects.

Please help me by adding some captions that include title, name, date, comments for your pix.

Congratulations to all and thanks for a great mini!

• Working circuit, software and parts for controlling at least 4 motors/lights independently with 4 photo-resistors; this must be prepared, assembled and ready to view at the beginning of class; there will be no time for problem-solving
• Sketches for “the stage” for your final project; the stage should help you fasten your components (motors/lights) and present your collected miniature objects.  Be prepared to share drawings, sketches, descriptions and reference images for how you will go about designing and making a “stage”.  Each student will be expected to give a 5 minute presentation on their research/ideas for how and why the objects she has collected will be displayed and animated.

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):

• “Analog input pin”: connection to one of the analog sensing pins (pins 11-21 of a for a Teensy 2.0)
• “photoresistor, flex sensor, force sensor, etc”: any variable resistance component
• “fixed resistor”: the value of this resistor should be selected based on the resistance range of the sensor
• “+5V”: connection to the microcontrollers +5V pin (labeled “VCC” on the Teensy 2.0)
• Ground: connection to the microcontrollers Ground (labeled “GND” on the Teensy 2.0)

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)
