Drawing Machine

Tuesday, June 26th, 2012

A drawing machine / pen plotter, means of drawing without drawing. This project is the next step in a series of programmatic eliminations of the artist’s labor from the drawing process.

This device suspends a pen holder between two stepper motors. Software interprets SVG drawings and sends G-CODE to the steppers to move the pen.

The drawings are in chronological order.

AM/RP with Mark Ganter. http://open3dp.me.washington.edu/
Awesome!
My research project with Josh Peterson http://design4.me.washington.edu/bin/view/AdvRP/JoshRobertFinal
It’s going to be a great experience.

Compiling/running CMUSphinx EvalDictator

Wednesday, November 3rd, 2010

A few simple steps to get CMUSphinx EvalDictator running in OS X 10.6.

1. Check out the source for cmusphinx tools:

svn co https://cmusphinx.svn.sourceforge.net/svnroot/cmusphinx/trunk/tools sphinxtools

2. Set environment variable JAVA_HOME:

This variable should point towards your java installation. Edit .bash_profile in your home directory, and add the line:
export JAVA_HOME="/System/Library/Frameworks/JavaVM.framework/Home/"

Quit Terminal and start it again.

3. In your sphinx tools directory (sphinxtools/dictator/build) edit build.xml:

In the path section, change${env.JAVA_HOME}/jre/lib/javaws.jar" to ${env.JAVA_HOME}/lib/javaws.jar.

4. In that directory, type ant to build the application.

5. Run Sphinx: java -mx256m -jar dictator.jar

Body Temperature

Thursday, October 14th, 2010

Where is body temperature measured?

Your body temperature can be measured in many locations on your body. The mouth, ear, armpit, and rectum are the most commonly used places. Temperature can also be measured on your forehead.

What is normal body temperature?

Most people think of a “normal” body temperature as an oral temperature of 98.6F. This is an average of normal body temperatures. Your temperature may actually be 1°F (0.6°C) or more above or below 98.6F. Also, your normal body temperature changes by as much as 1°F (0.6°C) throughout the day, depending on how active you are and the time of day. Body temperature is very sensitive to hormone levels and may be higher or lower when a woman is ovulating or having her menstrual period.

A rectal or ear (tympanic membrane) temperature reading is 0.5 to 1°F (0.3 to 0.6°C) higher than an oral temperature reading. A temperature taken in the armpit is 0.5 to 1°F (0.3 to 0.6°C) lower than an oral temperature reading.

Design and Construction of a Quad Rat Vitals Monitor.

J. R. Feddes, J. A. DeShazer. Development of a Portable Microprocessor for Measuring Selected Stress Responses of Growing Pigs. Transactions of the ASABE. 36(1): 201-204. @199

The development of a non-restrictive method for measuring selected stress responses of growing pigs in their environment is important to assess the acceptability of an environment for the pig. Blood pressure, body temperature, and animal activity are three measurements that can relate to stress of an environment. A portable microprocessor-controlled data logger was developed to measure these three parameters every 16 min over several days. These measurements were found to be accurate when obtained from the data logger strapped to a pig. Surgical techniques were developed to obtain blood pressure and body temperature. Specific data collected from this study showed that typical blood pressure for a growing pig (35 kg) is 80±5 mm Hg, blood temperature varied between 398 C (thermoneutral) and 428 C (surgical recovery) and the pig was active 26% of the time.

Biofeedback Video Editor…. I like the force-sensor collar to get a heartbeat… maybe they will respond to my comment on YouTube and tell me what kind of sensors they used. Edit:They did! A large square FSR placed near the jugular. Thanks youmadeline85!

DXARTS

The only news, really, is that I have finally made it up to UW and have started the DXARTS program. It’s great so far!
I’m not yet up on the website:

Generating NTSC with Arduino

Friday, March 12th, 2010

Convert an indexed grayscale image (16-color) to a list of hex values for use in arduino program.

png2avr.py


 # copy-it-right
 import sys
 from PIL import Image

 def main():
     image =Image.open("robert_index.png")
     out_f = open("robert_index.txt", "w")

    #image = Image.open(sys.argv[1])

    assert image.mode == 'P', 'image must be indexed'

    #sys.stdout.write(chr(int('11111100', 2)))

    for i, px in enumerate(image.getdata()):
        if(i%160==0):
            out_f.write('\n// '+str(i/160))
            print('\n// '+str(i/160))
            #sys.stdout.write('\n')

        out_f.write(hex(px)+', '),
        print(hex(16-px)+', '),
        #sys.stdout.write(hex(px))
        #print('.')

    out_f.close()
