character map

2009-04-10T21:55:00.005-05:00

while drawing schematics in class this week it became nessasary to type the symbol Ω for component identification purposes. a number of special symbols like this are assesible through character map. to find character map go to start>all programs> accessories> system tools> character map. other available symbols are ©, ® and the every popular☻.

have a good weekend.

rules for drawing schematics

2009-03-24T19:48:00.002-05:00

following are some rules for drawing schematics:

organize the schematic to a specified page size
apply proper symbols and reference data for each component
create general notes or legends that explain specifics
lines should be 0.125 inches (3 mm) apart for good reproduction
lines between components should take the shortest path
connecting lines should have a minimum of crossovers and jogs
long parallel lines should be arranged in groups of three
avoid four way tie points or four way functions
power sources should go up and ground sources should go down
all lines will run horizontally or vertically and connect in 90 degree corners

have a good week

autocad drawing

2009-03-13T22:34:00.007-05:00

i completed this drawing before we left for the weekend.

it is an electronic schematic

so far this class has been very good

i have learned some new things and had some good review

have a good week

stake board - template for laying out cable assemblies - we are reviewing terms used in wiring diagrams and schematics for electronics drafitng.

ductile

2009-02-12T18:36:00.002-06:00

in my manufacturing processes class we were discussing the word ductile. it means easily stretched without breaking or lowering in material strength.

autocad 2009

2009-02-05T17:14:00.003-06:00

we are using autocad2009 at school this semester. one new thing i like about it is that the tool tips that appear hovering over an icon expand into a help menu. i also have changed the background of my version to #000033. clicking on the image to the right yields a larger image for viewing.

thanks for reading.

Gran Torino

Walt Kowalski (Eastwood) is a retired auto plant worker whose wife has passed away. He lives in a neighborhood of immigrants and spends his days drinking beer on the front porch and recriminating the past. Forgiveness of others (and ultimately himself) is not a concept he wishes to consider.

A Korean War veteran, Kowalski holds disdain for his Asian neighbors which boil over at times into clashes with them. Over time and shared experiences he softens his stance toward his neighbors and even socializes with them.

This movie is not for children. Beyond the strong language and violence it is a story about racism, acceptance and a man who ultimately chooses one life over another. In the end, Kowalski reconciles his past through forgiveness and sacrifice.

Eastwood sings a few bars of the movie’s theme as the camera fades to the final scene. For Eastwood fans, that alone is worth the price of admission.

went to see eliasson exhibit at dma. it was unusual. he uses light, mirrors and other objects to create art that almost played tricks on your eyes. an artist from his studio gave a lecture before the exhibit formally opened. a good time was had by all.......even me.

hello

2008-08-10T20:59:00.002-05:00

been on vacation for ten days. i visited three museums. the kimbell, the modern and the meadows museum at smu. i ate and slept. i pulled up some rose bushes and installed a bird bath. start school in about two weeks. thanks for reading.

no new news

2008-07-14T23:12:00.003-05:00

not much going on. posted some pics. added some links. im about to finnish my dreamweaver class. i have learned alot. enrolled in civil drafting for the fall. i still need to add one more class...peace. out.

you got a lot of NURBS!!

2008-05-01T12:30:00.001-05:00

non uniform rational basis splines that is!!

development of NURBS (non uniform rational basis spline) began in the 1950s by engineers who were in need of a mathematically precise representation of freeform surfaces like those used for ship hulls, aerospace exterior surfaces, and car bodies, which could be exactly reproduced whenever technically needed. prior representations of this kind of surface only existed as a single physical model created by a designer.....cool.

soh cah toa...

we had a math review in my strength of materials class about a week ago. some of the students were trying to remember the trig functions and came up with this device:

sin
opposite
hypotenuse

cosine
adjacent
hypotenuse

tangent
opposite
adjacent

this class has been one my favorite so far. i am in a good group.
we have had a lot of fun and learned many things.

have a good day.

nothing new...

worked on site the past couple of days. modified site and blog. went to class. watched election coverage. ate some chicken.

topo survey

2008-02-21T13:12:00.006-06:00

today in topological drafting we surveyed the court yard outside the engineering building. we used a topcon transit like the one pictured here. we plotted 4 angles of the property and recoreded the measurements for later use. it was cold outside and a small amout of moisture began to fall as we concluded the survey....now I am going to eat lunch and then go to work. tomorow i am attending some training for work in downtown dallas. i am also starting to come to the conclusion typing in small letters all the time is not as great an idea as i first thought.

have a good day.

more from school...

tool tips are small graphic boxes that appear when using web sites or programs. they display information about the icon or element that is currently being hovered over with the mouse pointer.microsoft has refered to them as screentips.the image above is an example of a tooltip that is on my own site domaindesigngroup.com....thank you and have a good day!

sorry about the weather....

2008-02-05T14:00:00.000-06:00

it rained last night. the lightning was bright. the thunder rolled long and low. i could hear the rain patter outside and on the window. it was relaxing. then i went back to sleep.

peace. out.

what I learned today...

2008-01-29T13:46:00.000-06:00

today i learned:

right click is a very powerful funtion on the mouse.
format command enables one to change atributes of things like text, lines or other objects on a global scale.

have a good day!

school

2008-01-27T19:36:00.000-06:00

last semester i completed two classes. the first class was an introduction to autocad. it is a program that is used extensively in architecture and engineering. we plotted house plans and other general drawings to gain some knowledge of basic autocad usage and technical drawing.

the second class was an introduction to a program called solidworks. it is used for technical drawing as well. we drew mostly small mechanical parts. solidworks was probably the easier of the two.

this semester I am enrolled in topological drafting. it is concerned with plotting buildings and other structures from notes and measurements taken by surveyors.

the second class I am enrolled in is called strength of materials. it is concerned with measuring and calculating stress and failure of materials like steel, aluminum and brass. before stressing the specimens measurements are taken. then we use large machines that pull, smash and twist the materials. afterward, measurements are taken again for comparison and analysis.

i have taken many classes and the technical drawing curriculum has been my favorite by far.

have a great day!
