2da Parcial!

We have created an audio system with circuits and lasers basing in projects that are already out there in documents and records. We did not copy, we just looked at examples, tried to understand circuitry, connections, and signals and applied what we had to our project. There is still doubt on how to improve the prototype but, in all, if it works the way it should, we are satisfied although we will still try to improve the system as much as we can.

The activities we did weren’t all applied. We left some out do to realizing that some of them weren’t necessary. The one we did well, are and will be shown when presented. They are very simple but, effective when applied. They are for example, set up, connections integration, etc. The sound quality coming from the speakers isn’t the best. That’s what we have to work on and also design a real body for the project and not just have naked circuitry presented.

Third partial

In this semester the integrator proyect consists the chemicals reactions they are oxidation and reduction and consists in make a pail electrolytic that generate a some voltage, but as this pail generate a voltage very low and we need cover a voltaje mínimum the 15v and for can this objetive is needed make or buil a battery in witch is installed a strip the pails electrolytic that generate a 1.5v and so to cover  the share defined as mínimum because as they have a definite life time the preference have and keep a voltage highest of the 15v and keep for a time ans so can calculate the life time of the our battery.To do this is pretend usin home materials and so skip using the materials most pollutants for the enviroment. 

In this partial the principal objective was to ensemble all the ideas we had and researched along the first partial. The principal struggle with this task was obtaining the materials that we needed to complete the second phase of our prototype because most of our established chemical reactions were think to have chemicals that we needed to order outside the state, with this complication we had to think a fast strategy to complete our prototype , we used materials that were easier to get and gave a good result for a test, there were struggle with the team working because some of the members weren`t able to work along with their teammates because they had to work but we managed our times to try out the best of our team and use the time with more solid work ideas, this partial was a testing one , but we managed it well until the end.

ConclusionIn this partial, we achieved the objectives we planned in the beginning of the semester, we had some difficulties along the building and development of our battery but we did the enough effort for making the project possible. We took care about many things during the building of our project, not only about the functionality but the looking and vibe of the finished product, because finally it’s what it is, a product.About the knowledge, we‘ve raised new abilities that will be tested along the career and the projects that will need to be realized. Most of us now are taking the career more seriously the fact of learning and giving an effort to the career , this project was a testing one because we had a really big contact mostly with chemistry and electricity and the risks of the manipulations of chemicals and its reactions, but it was a great experience.

First Proyect Report! Second Partial.

Proyect Report!

Project organization.

The leader of distributed team work, which each of my colleagues investigated on questions assigned to each subject, my I touch me investigate the chemistry and electricity and magnetism and finally together research to complement the document.

Finally my team and I work very well and eventually studied on each subject, I also learned a lot about the electrochemical battery, in short for our project, the battery we have to do is to generate 15 volts.

To do this is pretend using home materials and so skip using the materials most pollutants for the enviroment.
