Week 9 Lab

During lab, Meghan and Anna discussed what was going to be done during the rest of the week in terms of testing. For the rest of the week, the team would conduct test to take measurements, make the powerpoint, and do the listening tests with friends. They were let out of class early so that they could bring the speaker stand to the dorm where the speakers were. While at the dorm, they tested the stand out to hear the difference and were excited to see that the project was a success.

Week 8 Lab

In lab today, the team worked on finalizing the blog and working on the final report. Dr. Knight gave the group a marked up copy of the Draft Final report and talked about some revisions that needed to be implemented for the final draft. The team decided the night before that the testing and measuring would be done outside of class, so the group will meet up later in the week. The team also thought of ideas on how to make the tutorial page for the blog.

Week 8 Pre Lab

The team met up the night before lab to completely finish building the stand. The top plate was drilled and attached. All of the screws, nuts and bolt connecting all of the components of the stand were tightened. The team decided that it would be impractical to bring the stand back and forth between the lab and dorms, so it was decided that the stand would remain in the Resident Hall.

Week 7 Post Lab

Since the poles were attached to the bottom base, the sand could be added to the each of them. Meghan filled the poles with sand and to avoid it falling out of the bottom, Anna and Dana suggested to put a plastic bag with sand in the bottom and then fill sand on top of it. While filling the poles, there was sand coming out onto the bottom base since the brackets weren't screwed tight enough onto the base. To finish filling the sand, the power drill was needed, so the poles were filled with as much sand as possible to avoid all of it spilling out.

Week 7 Lab

During the lab period, Dana and Meghan went to the Drexel Machine Shop to get more holes drilled into the poles, since the power drill stopped working the night before. While they were there, Anna developed ideas on how to do the testing for the loudspeaker stand. After the Machine Shop, the group started putting the brackets on the poles to attach them to the bottom base. There was a problem with how close one of the holes were drilled, so Dana and Meghan had to drill a bigger hole so that the screw and bracket would fit correctly. All three poles were added to the bottom base by the end of the class.

Week 7 Pre Lab

Dana and Anna meet up to start putting the stand together since all of the materials arrived or were purchased. Holes were drilled into the poles, so they could be attached to the base plates with brackets. The feet on the bottom base were also attached. Later, each member worked on the Final Report Draft that is due tomorrow at the beginning of the lab period.

Week 6 Lab

During this week's lab, the basic building materials were brought to class to start some measuring for the components. The wood that was brought in for the top and the base of the stand is 11.5 ft. and the team determined that each plate will be 11x11 inch squares. The poles that are being used are being cut down to 4 ft. on Wednesday afternoon (5/6/2015) in the Drexel Machine Shop and each are 1.5 in. in diameter. A 3D image was also made on Creo for the design of the stand.
