My project simulates a hydration sensor, to check if you are sufficiently hydrated, as it is a very essential thing in our body, as dehydration can cause fatigue and nauseas.

I have adapted it to be a conductivity sensor. For example, if you put a metal or banana or fabric with water and salt, on it, the green LED turns on. On the other hand, if you put your finger on it, it will not turn on because it isn't conductive. I made it with a 4.5V battery connected to a resistor where it goes directly to the LED, and then connects a brad on another part of the battery and the other brad to the resistor. I use plastic, a green LED, an inner tube, wires, a resistor, 2 brads, tape and blue foam.

If you have high conductivity indicates high hydration. Also with low conductivity you are dehydrated. The green light indicates conductivity and hydration. This device can be used by everyone no matter their age.

Project Statement

My project consists in color changing glasses to see your surroundings with a calm color filter. Using color psychology, we can affect the human mood though calm colors (such as blue or green) to help relax when feeling stressed, nervous or agitated. 

These glasses have removable lenses (made with color cellophane) to pick the color the person desires to see their surroundings. And the interior part of these glasses are covered with foam to make them more comfortable and relaxing.

These glasses are for those who often feel stressed, nervous, agitated, anxious or even have trouble to go to sleep, and will use these glasses to calm themselves if they are going through a stressful time or feel the need to feel undisturbed.

My project is based on a shoe insole with a heater that serves to avoid cold feet. I have created it because cold feet are unpleasant and my idea is quite good to avoid it. 

That project can avoid the hypothermia, the project is quite important, it helps people with cold feet.

For the prototype I have not used complicated materials, cardboard, nicrhoma wire, an energy generator and some cables to connect them with the generator to the template.

People with cold feet will use it to avoid having it anymore.

The project is about a necklace with different cologne pots inside it. These will contain a different fragment each.

The idea is that the smells that are in the pots are of a specific memory or sensation. It has been proven that smells make you remember and transport you in some way to the place where you smelled that aroma, so when you put one of the scents on it, it will be to remember or feel something again.

The necklace can be very helpful to people who are having a hard time and want to be able to remember what it was like to be happy to move on ... Everything and what I know, it can be used for many other things, such as to help remember people with , for example alzeimer.

The materials I have used to make this example of a souvenir necklace is mostly wood. This has been custom cut and designed to fit. To simulate the different cologne bottles I have used different colored straws to simulate the different essences.
