~ELEVATOR PROJECT~

We have done an elevator at our technology class. We choose this project because our teacher said that it was a great idea. Here we are going to explain how to make it.

~MATERIALS~


Shaft of the elevator:
-Plywood (30cm) x3
-Base of plywood
-Sprays (grey and black)

 Box of the elevator:
-Plywood x5 (x2 of 10cm and x3 15cm)
-Thread of fishing

 Mechanism:
-Nail
-Silicone
-Three circles of plywood (2 big and one small)
-Motor
-Gears
-Switch





~HOW TO MAKE THE SHAFT OF THE ELEVATOR~

We pin with nails the three plywood between them and after we pin the box on the base and we paint it with some sprays.

~HOW TO MAKE THE BOX OF THE ELEVATOR~

Like the shaft of the elevator we pin  the five plwood between them. Also we paint it and we make a hole in the top of the box.

~MECHANIMS~

After do the hole on the top of the box we bring in the thread of fishing and we seal it. Also with the circle of plywood we make a pulley and we put them on the top of the shaft.
For what the elevator move up and down we have to do a circuit. We take the battery and conect to a motor by two switch.

HOW DOES IT WORK?

To work we had to place two wires that went through a switch but we had a problem, couldn't go down and up in the same way so, to go up we had to connect a wire to the positive and another to the negative, obviusly, and to go down ou have to put them backwards, as in the example.

~LIGHTHOUSE PROJECT~

In our technology class we have done a lighthouse. Here I'm going to explain all the things we did.

INTRODUCTION:

~THINGS YOU NEED TO MAKE IT~
-a plastic bottle
-small light
-wire
-battery
-colour cardboard
-wood base
-insulating tape
-switch




























~ WHAT ARE IT DIMENSIONS?~
It isn't very big, the base is about 15x20cm approximated

~WHAT IS IT FUNCTION?~
The function is light, you can use it like a lamp
















TECHNICAL ANALYSIS:

~HOW MUCH IS THIS PRODUCT SOLD?~
 To make it you haven´t got to spend much money

~HOW MUCH DOES IT COST IN THE SHOPS?~
You can´t buy it on shops, but you can make it on your house with cheaper materials




SOCIO-ECONOMIC ANALYSIS:

~ANALYSIS OF FORM~
 -What are it exterior measurements?
Base: 33x26cm
Lighthouse: 18cm of height
-What shape is it?
The light house is cylindrical, and the electric power  is cube-shaped

~ANALYSIS OF FUNCTION~
A lighthouse is used as a reference and coastal warning for sailers. They are crowded by a powerful lamp that serves as a guide.

-How does it work?
It has a battery connected by wires that transmit energy to a light. You can turn on or turn off the light with a switch. Is similar to a lamp.

-Problems
If you don´t connect correctly the wires, the light will not light

ELEMENTS
-light bulb: emits light
-battery: emits energy
-wires: transmit energy
-switch: turn off or turn on the light
