Write problem/project Goal
To build a small wind tunnel which can test the aerodynamics of objects.

My First Task
Over the first weekend it is going to be my job to finish the compressor and diffuser as well as begin working on the test section of the wind tunnel.

Summary of actual work over first weekend
Over the first weekend it was intention to simply make the base for the entire wind tunnel by taking a sheet of particle board and making multiple cuts to it to form the shapes necessary for the perimeters set forth by the group. This changed because there was a few problems that I ran into which altered my path to completing the task. This included measurement problems, improper equipment, and human error which I had to take into account afterwards and correct.

Week1 Narrative
Tell a detailed story describing what you did for your team over the weekend.

My Second Task
Record what you are planning on doing for the team during the second weekend.

Over the next weekend it will be my responsibility to cut the plexiglass for the test section and begin research on the wind speed monitor and the device we will use to monitor air flow over objects.

Summary of actual work over second weekend
Over the second weekend, I only planned on making the feet for the wind tunnel. However, I realized that on the mainframe I mis-measured one of the cuts so I had to also cut out two wedges to compensate for my mistake.

Week2 Narrative
Tell a detailed story describing what you did for your team over the weekend. First I brainstormed Ideas for how to attach the mainframe to the other pieces. I realized that I could not nail or screw them on due to the length of the board. I also realized that glue would not be a good compromise because it would be a loose bond capable of bending and breaking. Because of these issues I decided the best Idea would be to attach them with feet on the bottom that overlap the edges. Not only would this secure the pieces in place but also it would give us the opportunity to place some sort of anti-vibration compound on the bottoms of the feet so that the wind tunnel does not vibrate or move due to the power of the fan. I then decided to take a sheet of 1/2 inch ply wood and cut out 10 feet for the wind tunnel. Each foot is about 1"x2". 4 will be placed on each end of the windtunnel in a box shape with two in the middle of the wind tunnel. I then had to factor in my mistake on the measurements for the mainframe into my work. So, I cut out two wedges which could be adhered onto the edge of the mainframe making a tight seal. I measured out two wedges which were about 1 inch wide and angled down to a minute width. I then cut these with a circular saw.

My Third task
My third task will be to start cutting the plexiglass and finding a way to cover the feet so that there is no vibrations from the fan.

Summary of actual work over third weekend
How is what you did different than what you planned?

Week3 Narrative
Tell a detailed story describing what you did for your team over the weekend.

My Fourth task
''Record what you are planning on doing for the team during the final weekend of project work. ''

Summary of actual work over fourth weekend
Over the fourth week I simply thought I would have to repair the missing wedge on the wind tunnel and attach the anemometer along with beginning the standardization of the device. however, instead I found myself beginning to cut the plexi glass and attaching it to the wind tunnel.

Week4 Narrative
Took a piece of 1/2 inch plywood and cut out a wedge to attach to the windtunnel. Applied wood glue and attached the piece to the windtunnel. Then applied a vice to bond the wood.

Anemometer -found a light bulb that had a working filament -Heated the bulb with a heat gun thoroughly for 2 minutes then placed the bulb in a cup of cold water This effectively shattered the glass but kept the filament in tact. -I then dried the bulb _after it dried I soldered on two wires to the filament. One to ground and one to the current so That it could be hooked up to a power source. -then I hooked up the filament to an external power supply and attached a meter to the filament to read the current. - to find wind speed readings I blew on the filament. This changes the temperature of the filament and increases the current. -The anemometer still needs to be standardized so that specific measurements for speed can be attained.

Plexi-glass -I took sheets of 1/8th inch plexi glass and viced them to the table. -I then marked out my measurements with a dry erase marker. -Following that step I scored along my marks with a box cutter. - Then I placed the scored edge along the edge of the table and snapped the plexiglass. -Sometimes this did not work and left uneven edges and shards, however after practice the edges became clean. -To attach the plexi-glass I took a rabbit and then grooved the edges of the wind tunnel so that I could insert the plexi glass along with liquid nail compound to bond the plexi-glass to the wood.
