First, we started talking about the functions that the assistant need to have and figuring out what we needed in order to put together the circuit. Also, with this initial information and goal we started building the code we needed to make it work. 

TinkerCad helped us testing some connections. 

At first we didn't knew how we wanted our project to look. So we started sharing ideas and  drawing them in order to reach a design that the user can carry without difficulty, attractive to the eye and that inspires confidence and peace.

We used Fusion360 to model the shell of our project taking care of the space needed inside, and the components. Also we started talking about materials we could use, light colors, etc.

When we were sure about every feature in our design we started the 3D printing. It took us almost 17 hours to achieve our goal, but the wait was worth it. 

In order to make our project work, we found the nearest store and bought everything we needed to create the circuit without having problems.

One feature that we couldn't test on tinkercad was the oled screen. So carefully we connected it to our Arduino software and we started testing the code to make sure it worked the way we wanted.

Once the codes and circuits were tested, we started welding everything together making sure everything will fit inside our shell.

Even though the shell was materialized as we wanted, we sand the impression and painted it the color we imagined our design.

With all the circuits done and the shell ready, we start to carefully assemble everything in the locations we planned the components.

At last we tested again that everything worked and closed the shell.
