Winter session - Wood shop week 6

Finally a table!

Winter session - Wood shop week 3-5

Making of coffee table (machogany, glass)

Winter session - Wood shop week 2

A shelf for viewing strange and unusual. Plywood, Watco fruitwood oil stain (top), Watco red machogany oil stan and black pigment.

Winter session - Wood shop week 1

Week 1::
1:6 scale moquettes of "pedistals" design, due in 24 hours from assignment

1. Model for magnyfyer display (for viewing really small and strange things. shown with a grain of rice) 2. Shoe mirror pedestal 3. A "hairy" leg which was consieved out of desperation and time limits

RISD Wintersession 2007

From Immaterial to Material lead by Tucker Houlihan (second from the left)

End of the semester mistakes!

All right, i'm installing Wordpress blog after all - just realized that i didn't publish my draft blogs since...a couple of month back, which is bad because people must have been looking for them. Oh, well - i'll try to upload them in a bunch (hopefully won't have to do them one by one).

Broken screen - quite literally

Just another day visiting New England Tech. Saw a student trying to adjust system preferences to fix this one!

Experimenting

Thought this would be fun. Shapes are traced from medical imaging scans.

Inner Critic

You will have to enable your mic (would be internal if you are on a laptop). I showed this as an installation for the RISD Open Studios in Oct, projected on the wall and pinned blank index cards and a pen onto same space for people to leave comments on their own inner critics.

It was fun untill my PowerBook internal mic started adjusting its levels to the background noise, thus decreasing sensetivity. Will use external directional mics next time.

Mediation

"The mass media are genealogical because, in them, every new invention sets off a chain reaction of inventions, produces a sort of common language, They have no memory because, when the chin of imitations has been produced, no one can remember who started it, and the head of the clan is confused with the latest great grandson. Furthermore, the media learn; and thus the spaceship of Star Wars, shamelessly descend from Kubrick's , are more complex and plausible than their ancestor, and now the ancestor seems to enfiriour their imitator"

Christmas is near...

"I have admired many people. I have always considered myself a crooked tree, so straight trees earned my respect. Indeed, we should remember what happens to us before Christmas when we set out to buy a Christmas tree. Rows of lovely trees, and all of them look terrific from a distance, but close up, none of them really meets our desire for an ideal tree. One is too think, another crooked, the third too short, and so on. It’s the same with people; no doubt some of them seemed so imposing to me because I did not know them better, while I knew my own defects only too well."

Didn't work without padding it a bit

Trying to embed pressure sensor behind canvas

Servo/Sensor/Flash

Pressure sensor is now driving the motor and sends corresponding values to Flash application at the same time.

When pressure increases, the motor is driven up and when decreases, it turns back down. So far it only rotates 360. Arduino code below::

/*
Servo control from an analog input

The minimum (minPulse) and maxiumum (maxPuluse) values
will be different depending on your specific servo motor.
Ideally, it should be between 1 and 2 milliseconds, but in practice,
0.5 - 2.5 milliseconds works well for me.
Try different values to see what numbers are best for you.

This program uses the millis() function to keep track of when the servo was
last pulsed. millis() produces an overflow error (i.e. generates a number
that's too big to fit in a long variable) after about 5 days. if you're
making a program that has to run for more than 5 days, you may need to
account for this.

int inByte = 0;
int servoPin = 2; // Control pin for servo motor

delayMicroseconds(pulse); // Length of the pulse sets the motor position
digitalWrite(servoPin, LOW); // Turn the motor off

Serial Communication with Flash

Finally got Flash to talk to Arduino. Turns out you have to install Dan Sullivan's serial server (http://itp.nyu.edu/~dbo3/SerialServer/SerialServer.html) and make sure to send data in dec form terminated by 0. This setting seems to work pretty great::

java -jar /Applications/ss6.jar SerialPort:/dev/tty.usbserial Baud:9600 SocketPort:9001 Sub0ForChar:13

Of course the Port will change depending. As far as flash goes, XML socket takes data in , so if there is more then one value passed (for instance, the switch and an analogue sensor), you have to adjust for the lack of structure.

What i did is set up a "control value" in Audrino code (say control value is 999) and set up an array in flash that stores data each time it's passed until it encounters control value. That way i can pull array[1] as first sensor, array[2] as second and so on.
