Week of 1/31

This week our team worked on brief lightning talks to update the rest of the group on our progress and our plans for this semester. Topics include design changes to the model to account for aesthetics and implementation of boundary surfaces. Biggest efforts as of now are to find a reliable printing source.

Our lightning talk can be found here:

Week of 1/24

This week, the meeting was short but the team gathered together to plan the lightning presentation for next week. The presentation plans to briefly discuss an overview of last semester's progress and discuss this semester's plans and goals for maker faire.

Week of 12/6

This meeting was the last of the semester before winter break starts. The last of the presentations of the groups were done today. The 12th scale cabin team's presentation can be found below. For a quick recap of the progress done so far:

• The team accomplished fabricating two cabin designs
• Prototype 1 satisfied the function of housing the controls without excess space
• Prototype 2 touched on a more aerodynamic and futuristic aesthetic
• Conducted an aerodynamic analysis of the cabin
• Begun conceptual designs of Prototype 3

The printing of Prototype 3 will be done by the beginning of then next semester. In the meantime, Prototype aims to be a further refinement in aesthetics while the attempting to fulfill the following functional goals:

• Sustain a fall from 3 ft fall with all the components contained in it
• Proper air ventilation (heat from internal battery) 
• Develop a compartment system for all the internal components
• Find a proper door alternative that is safe and convenient

Week of 11/29

This meeting was spent mostly by listening to final presentations of the Full Scale Team and one 1/12th Scale Team. After presentations, it was agreed to have a printing of Prototype 2 done by next meeting. The Cabin team is still waiting on a response to Professor Yousseffi of the Mechanical Engineering Department. Our Presentation 3 was completed this week but we will post it here the following week after our presentation.

Weeks of 11/15 - 11/22

For the week of 11/15, the team together simply worked on finishing the second potential Prototype 2 of the cabin. Here, the final 3D CAD model of the second prototype took into account of the speedboat like design of the drawn concepts mentioned in the last log. The final model went with a more bullet-esque design compared to the first concept of prototype 2. A final choice of which concept to choose for the final Prototype 2 will be considered to an aerodynamic analysis and realistic factors as in fitting components and if it is comfortable when translated to full scale. For the Week of 11/22, the team will take the week off due to Thanksgiving break.

Week of 11/1

During the 11/1 meeting, it was fairly short again as the control's team did not have all their parts in as well. The controls team did not have most of their parts, but they did have their battery, which is their largest component and we began dimensioning Prototype 2 based on that. Also, sketching and CAD of 1/2 of the possible Prototype 2's have been drawn. Here, aesthetics and aerodynamics will be more of a concern. Concepts and paper 2-D drawings have been done by Darren and 3D CAD modeling by Kaelan. Once CAD is finished, aerodynamic qualities will be calculated and examined. This will be used as one of the deciding factors in the final design.

Week of 11/8

This meeting saw the 3D CAD modeling of 1 of 2 potential designs of Prototype 2 finished by Kaelan. The first design mainly went for a slender and aerodynamic asymmetrical design. As he did this Darren started drafting the second potential design that incorporated a more compact and bullet-esque symmetrical design. CAD modeling for this design is expected to start next week. Based on the progress so far, the team is actually 1 week behind schedule. So hopefully by the end of this week, 3D printing will begin on the preferred design of Prototype 2.
