The first thing that Neil tells us is that it is an unusual class and that the next week we will have the break. He also explains a little what awaits us after the week of the break. It explains what we have to do the week of the wildcard and the part of the machine week. Then he begins to explain the assignment of the week, which is to answer the questions according to our final project. After this, he begins to explain different parts of projects and different final projects that have been carried out during the years in the fabacademy. very interesting and ambitious projects.

This week is going to be more quiet, since I have quite clear my final project and I only need to express this in the questions that must be answered.
For that reason I am going to use a couple of days to answer them and upload them to the web page and the rest of the days I will try to recover the previous assignment since I have not been able to upload any of this to the web. Even having the neopixel array created and soldier to upload it to the webpage.

This week's task is to answer the following questions that are proposed about the final project of the fabacademy:
WHAT WILL IT DO?
It is a safety element for bicycles divided into two parts, front light and rear light, which affects both the user of the bicycle and the vehicles around it. It is based on the regulations that exist in Spain to leave 1.5m between vehicles and bicycles, regulations that nobody respects. This safety element will warn both the driver of the bicycle and the drivers of other vehicles around that you are not leaving the safety distance indicated and therefore is putting the life of the cyclist in danger. This warning will be made by lights and sounds.
WHO'S DONE WHAT BEFOREHAND?
I was inspired by a commercial project called Lumos helmet, which incorporates the security lighting elements in an interactive helmet.

I have also been looking for different Fab Academy projects from years ago to inspire me and see what ideas they have been doing over the years:

WHAT WILL YOU DESIGN?
I am going to try to design all the parts of the project, incorporating both the physical part and the electronic part within the set without going through some standard measurements so that it is not very shocking for the user. I want the set to be as packed as possible and avoid as many connections as possible.
WHAT MATERIALS AND COMPONENTS WILL BE USED?
Machinable wax for molds
Transparent resin
PLA for 3D printing
Recycled wood for machining
Methacrylate for laser cutting
2 x 9V batteries
2 x 47 neopixel circular array
2 x buzzer
3 x ToF sensor GY-VL53L0XV2 I2C IIC
1 x bluetooth communication module
Different electronic components such as resistors, capacitors or diodes for the manufacture of PCBs
WHERE WILL COME FROM?
I will buy the materials from local suppliers or online suppliers
HOW MUCH THEY WILL COST?
Machinable wax for molds: 17€
Transparent resin: 6€
PLA for 3D printing: 16€
Recycled wood for machining: 0€
Methacrylate for laser cutting: 0€
2 x 9V batteries: 8€
2 x 47 neopixel circular array: 41,6€
2 x buzzer: 1€
3 x ToF sensor GY-VL53L0XV2 I2C IIC: 24€
1 x bluetooth communication module: 4€
Different electronic components such as resistors, capacitors or diodes for the manufacture of PCBs: 0€
TOTAL: 117,6€
WHAT PARTS AND SYSTEMS WILL BE MADE?
PCB and electronic communications
Software for the composition
Hardware to join everything
WHAT PROCESSES WILL BE USED?
Molding and casting
Computer-aided design in 2D and 3D
3D printing
Controlled computer machining and cutting
Embedded programming
Soldering
Electronics design
Networking and communications
WHAT QUESTIONS NEED TO BE ANSWERED?
How to communicate the three sensors with each other and with the LED array so that they act together.
How to get the sensors to capture different ranges of measurement and the LED array interprets each range.
How to feed the whole and get it to turn on and off.
How to communicate the front and rear lights without wires, with bluetooth module or wifi.
HOW WILL IT BE EVALUATED?
The first spiral that I want to accomplish is to get the rear light, which is the most important, and the one that will house the distance sensors to work, capturing the rest of the vehicles and, by means of light and sound warnings, indicate the distance to the that are found.
The next spiral will be to incorporate the front light from which the user of the bicycle will be able to observe by means of a series of LED the distance to which the rest of the vehicles are located, and also it will also be able to illuminate the front part.
The last spiral that could be realized is to incorporate an indication mechanism for the intermittency so that the pilot of the bicycle can indicate when it is going to turn in one direction or the other.

Conclusions

This assignment has helped me to clarify all the things about my final project, make a count and start asking for all the elements I need to carry it out and also it has helped me to think about starting to work on the different parts that make it up for later not having to do everything at the last moment.
