Two wire (power & ground), continuous rotation motors
Using pulse width modulation (PWM) to control the speed of DC
Use multiple electromagnets around gear to divide a full rotation into equal steps.
Requires extra controller.
Servo Motor: Generally assembled by a DC motor, a gearing set, a control circuit and a position-sensor (so position can be controller precisely).
Usually three wires (power, ground, signal)
Using pulse width modulation (PWM) to control the signals of servomotors.
Autonomous Objects: We are making a series of experimental prototypes that explore the ubiquitous but novel relationship between humans and objects. By reimagining the messages behind everyday objects, the project enables everyday objects to communicate and negotiate with us in their (possibly) preferable way.
1. Printer: A printer who needs a break occasionally.
2. Hand Dryer: A hand dryer who messes with you.
3. Clock: A clock from China who only wants to live in the Beijing Time.
I want to control the light in different rooms.
Use IR sensor to control the brightness of LED, and turn on/off of LED
1* IR sensor
1* remote control
2 * 220 ohms resistors
Wires & jumpwires
How it works
Button 1 : switch on/off of blue LED
Button 2 : switch on/off of yellow LED
Button + : increase brightness (++ 50)
Button – : decrease brightness (- – 50)
Two LEDs have different on/off state, but have the same brightness.
Two LEDs can’t be adjusted separately
The remote control is inaccurate
Utilize 4 small buttons to create a combination locker
Use 1 big button to submit & reset
Green and red led to show whether the passcode is right or not
Yellow led to show each correct press
The lock passcode: 4213
4 * small buttons
1 * big button
3 * LED (red, yellow, green)
5 * 10k ohms resistors
3 * 220 ohms resistors
Wires & jumpwires
How it works
Press the button sequentially once a time with no repeat
If it is in right sequence, yellow led will blink
Press the yellow big button to submit (and it will reset at the same time)
Green led means unlocked (right), red led means locked (wrong)
If you don’t start with 4, and then you pressed 4, then press the buttons in a right sequence, the locker can still be unlocked.
We choose transistors as our topic because transistors are fundamental in every modern circuit and can be used as either switches or amplifiers. But the principles and operations of transistors are too complicated to understand for people without engineering background. We have learned what is behind a transistor and how different transistors function. We found the metaphor that transistor can be described as the “valve.” What we are trying to do through the zine is to deliver the concept and functions in a more comprehensible way. We hope the layout is readable for screens and printed version.
Most of David Bowen’s projects focus on the recurrence of natural elements. Tele-present water is gathering real-time data from a remote unknown location somewhere in Pacific Ocean and transmitting valid data (intensity and frequency of the water wave) to this installation. As described on the website “This work physically replicates a remote experience and makes observation of the activity of an isolated object, otherwise lost at sea, possible through direct communication.”
My interest has been aroused while taking a different perspective. I found it sarcastic of the form choice. He is using the mechanical grid structure to represent a natural phenomenon and deliver loneliness and helplessness to its audience. Why a obviously unnatural structure rather than a replicant of natural water waves? Why in a museum with all the unnatural surrounddings? Is it a parody to the mechanized world?
