Smart Helmet¶

safety is the first thing everybody thinks about when they ride a motorcycle for the first time when you drive it you must always be faced on the road and be careful to what is around you, sometimes you are careful but the people around you are not and this what make motorcycle scary. and one day I saw an accident in front of me, and this accident make me think about how to make the ridding motorcycle more safe.

My Project is to make ridding motorcycle safer by making the helmet give you a notification when every car is in the blind spot or to close to the rider. This will make them know what happened around of them, and that how my project make the ridding more safe.

How it work¶

the Project contain of two devises one of them is attach to helmet and the other on the motorcycle.

the device in the motorcycle will have two ultrasonic sensor at each side at the back in the plate number of the motorcycle too cover more space behind the rider and if it since any thing in three meter and make light blink near the sensor, and at the same time it send data by Bluetooth to the other device that there is something behind you and this device that attach to the helmet have screen and this screen will show dingers sign without making the rider by making the screen reflect on transparent plastic on front of the rider eye. and the dingers sign will appear at the same side that someone close behind you.

the way that the rider will know if someone close form the back without disturbing the rider, so I did a small hologram the screen will show the dingers sign then it will reflect on prim and it will reflect it 90 degree after that I put 45 degree transferee plastic in front of the rider, so when there are something close to the rider from the back the screen will work and even if it dose it will not block.

Electronics¶

helmet device¶

you can find more information about it in the output device week here

the sandwich circuit it is three layer in front of each other, the first thing screen next to it is the microcontroller and some main component the last layer is circuit to contacted to the Bluetooth and power, this way of board help me to fit it all in small case.

Motorcycle device¶

you can find more information about it in the input device week here

I did the circuit to detect what is near the rider from the back by two sensor one at each side near to the sensor and give notification for the rider other people in the road that they are close to the rider by blinking light work when ever they are in rang of 3 meter.

Network¶

I used Bluetooth HC-05 Module in both of devices to transfer the data between then and it is harder than I think about it, but at the end I did it.

for more information about what use and how did I pear the two devices together and way I used this type of network and more you can find it in the Networking and communications week here

Code¶

helmet device¶

in the output week I explain how the code work in the code section here

 // the setup function runs once when you press reset or power the board
 void setup() {
   // initialize digital pin LED_BUILTIN as an output.
   pinMode(LED_BUILTIN, OUTPUT);
 }

 // the loop function runs over and over again forever
 void loop() {
   digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on (HIGH is the voltage level)
   delay(1000);                       // wait for a second
   digitalWrite(LED_BUILTIN, LOW);    // turn the LED off by making the voltage LOW

convert the photo to code¶

I used website to help me do this

this web convert the image to code then the so the read the code and convert it to image into the screen.

2D and 3D Modeling¶

2D design¶

helmet device

the thing that I was scare of it is how the screen will reflect and not disturb the rider, so I make Prototype about how it will lock and this help me in 3D design, the difficulties in this was how to give the good image and not disturb the rider how ever the hardies thing was to make the right angle.

motorcycle device

for the motorcycle device it didn’t need a lot of time , I just case for the sensors and lights, and ecteronic part will be back of at plate number

Prototype shape¶

In these steps I tried to make Prototype of my device case, how it will fit the helmet and the view angle:

First thing I did wax making the case for the dive using fome

Next I want to know the angle of the helmet, So I start cutting small pieces and glow them in the helmet side by side for same the long of the case, then I glow them together and I added some support

After that I remove it from the helmet and put in top of paper and make line on it, then I measured the angle by taking the height of the carve to the end line ever 1 cm, this will help me to do design.

3D design¶

the first thing I print using was the helmet attachment

helmet

the second thing was the sensor case that fit on the plate number from the back

where will they come from?¶

most of it I will order it online

who has done what beforehand?¶

there is some companies did prototype and other in the market .

Cross Helmet X1

Skully Fenix AR

The Bike Helmet

what questions need to be answered?¶

how to the rider will see the information with out git disperses ? how I will connected the two devises ? how the devises will git powered ? how far the sensor can detected what behind the rider ?

how will it be evaluated?¶

if the rider have clear view to front and back and can change the line with out any problem.

plan¶

week 10 : I made circuit for the ultrasonic and every thing well good just need to make the connection.

in week 12 : I made the second circuit and put in it small screen but I have problem that the screen some times work and some not.

in week 13 : still try to fix the problem at the end of this week I fix it .

in week 14 : I made what the screen will show

in week 15 : I started to make the Bluetooth connection between the two circuit.

in week 16 : I am trying to fix the network problem

in week 17 : I start making the final case for both devices and put the reflector.

Problems¶
