abstract


These electronic devices are based on the use of technologies for sending data via Wii-fi bluetooth etc. These technologies are subject to a wide range of protocols and standards that we find in most cases a constraint to the development of our daily work activities or however the emergence of new technologies such as Li family fi which offers an innovative way of transmitting or sending data using light as a transmission medium or more specific spectrum of light. This technology offers a host of advantages, among which include faster and faster as easy configuration using transmitter means the light beam can be achieved cost reduction and protection of the transmitter. About component specifications document that will be used for the construction of two elements (transceiver) designed to free communication as a means only using a light beam will. With these devices it is to make a point-to-point communication to a distance of approximately 10 meters. It is noteworthy that these specific details are required as provided in research as a real especio carried may be susceptible to change.

Conclutions:

report of project integrate 3 partial

Our battery contains sixteen bottles with a capacity of 75 milliliters each one. Each bottle contains 30 grams of magnesium sulphate and 15 milliliters of acetic acid, bar of copper and zinc. And this mixture provides us 0.95 volts inside of each bottle. Also all the bottles are connected in series For have more voltage. We made a wooden box to store all the bottles its measures are 20 cm of depth, 40cm of length and 13.5cm of height. The design is made in the program rhinoceros 4.0.

After our hard work in the three partials the results have been excellent according to the planning with the first and second partial because the final voltages have been the desired. By the other hand we are happy with the design of the battery and the wooden box. So we are happy because the battery provides the amperage needed for the circuit.

The more difficult was to make the voltage ascend to 15 volts or more and be stable, because the voltage decrease with the pass of time, but with practices and investigation we controlled the voltage and the time for more time.
