2nd partial

In this part is working in the design of the amplifier and the elaboration of the two circuits the receiver and sender. In the realization of estimates of both the current supplied in our system, the power and voltage. There was also the relevant tests with the laser and its handling of the signals and frequency. It was the price quotation of the materials.

Definition

*Multimeter

Is an electronic measuring instrument that combines several measurement functions in one unit. A typical multimeter may include features such as the ability to measure voltage, current and resistance.

 *Mini jumper cables

Cables with a kind of pliers in each jaws. They are used for connect some devices.

 *Led

a semiconductor device that converts electricity into light.

 *Resistance

reduce the flow of electrons through

 *potentiometer

is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider.

 *Cutting pliers

pliers that have a cutting blade on the side of the jaws

 *Cable

Device useful to transportate electricity from a battery or generator

 *Protoboard

Electronic device useful to realize electronic practices is made of plastic with metalic cells.

 *Photcell

This is a very small light sensor. A photocell changes (also called a photodetector, photo resistor

 *Transistor

a transistor is an electronic component used in a circuit to control a large amount of current or voltage with a small amount of voltage or current.

 *Capacitor

An electrical device used to store electrical charge.

 *Bakelite

plate to place circuits

 *Speaker

audio amplifier or to increase the volume of some sound

 *Soldering

Joining small pieces of metal together using molten metal

 *Welding

Fusing two pieces of material using a heat process; most commonly used with metal and plastics

 *Pliers

A clamping tool that can be used to hold objects while you're working on them

 *Plug

Cable for the sound

 *Plug entry

Entrace for audio

 *Solar cell

a cell that converts solar energy into electrical energy

 *Laser

light amplification by stimulated emission of radiation

 *Preset

variable resistor of special material

 *Scissors

and edge tool having two crossed pivoting blades

 *Wax welding

used before welding something.

 

Report

This project is the design and construction of a circuit for transmission and reception of audio by light, to each member of the team we played investigate and inquire about the item listing, prices, and think about the design of our audio system.
The transmitter is responsible for modifying the original information in such a way that may be appropriate for its transmission.
The means of transmission is that by which information travels from the transmitter to the receiver, by what might well be regarded as a connection between these some elements.
In the transmission of audio with laser, the intensity of the beam is modulated by the intensity of the acoustic signal, which is subsequently picked up by a photo detector circuit.
Also plan to construct and design an amplifier, either that by the time or the budget is not reaching its completion, we'll use a horn to the output of the sound.

Conclusions

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.

Conclusion In 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.
