Integrated System Build & Test

To view all up to date documents and files for this phase, please look in the Phase III folder.

We have made substantial changes to our design package which can be found here: Design Package. This includes all part drawings, exploded views, and a comprehensive Bill of Materials. The folders in this directory are organized by part number. The Hopper is still a work in progress as it is contingent on the parts we have drawn actually being machined.

One of the more exciting parts of this phase was the trip taken to Nicaragua by David and Sarah. David has developed several slides to outline what was learned on the trip and that can be found here: Nicaragua Trip Presentation.

David has also outlined some more detailed notes on this trip and will be adding to them as time progresses. the whole document can be found here: Nicaragua Trip Notes.

Finally, Enlace Project was kind enough to put together an Article and short video about the trip to Nicaragua. They can be found through the following links.

Team Vision for Integrated System Build & Test Phase

For the Integrated System Build and Test Phase our team goal was to have all parts machined, location information gathered, and have the housing system built and ready for testing. As the blades and spacers came in from machining we realized that with the over sized of our material order, we could add on to the overall size of our machine. Therefore we altered the overall length of the machine and submitted material for more blades and spacers to be machined. David and Sarah traveled to Nicaragua during our spring break in order to gather information about the local community and business culture that occurs in El Sauce. This information allows us to better understand how our system will be used by the locals, and develop operational plans for them. The trip also set up critical connections so that large parts (stand) can be machined locally instead of in the US, and set up a network of people willing to take charge of the upcycling process. (See Notes on Nicaragua for more information)

Unfortunately, the water jet has been out of commission for the past few weeks now, which has put our parts on hold. We have consulted with the machine shop on how we can get our end plates cut without the water jet. Of which, the answer seems to be the band saw and some hand work. Risks and problems have been tracked and are being addressed day-to-day.

Plans for next phase

During this next Phase, our team's plan is to finalize our remaining parts required for assembly and build our system. We have a contingency plan in place if the water jet is not back online by a specific date. If this occurs we will revert our design and cut the remaining parts using an alternate method. Once the assembly is complete we will streamline our Test procedures in order to get back on track. In our plan they are spread out over a longer period of time than they realistically require. At the end of this next phase we anticipate to have a fully functioning system and several completed tests.
