## Introduction: ByteCycle

### Why a smart green cycle?

Because we are ecologist and technological.

We want to fly away from motorbike at traffic light who make us breathe lot of
exhaust, and arrive to our office as if we'd just stepped out of the shower and not like smelly “traditional” cyclists !

### Which problem do we want to solve ?

We want to make more enjoyable go biking.

We want to solve the problems of continuous gear adjustement while moving in city traffic, as a car does.

We want to reduce maintenance and continuous gear changes.

The idea was born looking at auto and motorbike world: in fact no driver want to be in the traffic and make lots of speed changes for a good driving.

### How we did it?

We use the Intel Edison board connected with our smartphone to control all the processes: start, acceleration, speed, tilt and GPS positioning.

The Edison board and all sensors are self-powered with a solar panel.

### Teacher Notes

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

## Step 1: Step:1 Start Working

We chose a particular gear integrated in the hub ( a Shimano Nexus inter 7) that allows to change the speed also when we stand still and go fast as the traffic light turn to green.

We can choose to turn the automatic gear off and ménage the speed with a joystick as the sequential gearbox on your car!

There is a Led on the handle bars to let you know the speed rate and flashes if the battery is low.

The system is recharged by a solar panel located on the luggage holder so the system is energetically autonomous.

## Step 2: Step 2: Connecting Edison Board

Edison board recognize our phone via Bluetooth .

The gyro sensor controls the bike position and in case of fall the system, after 10 second, transmits a message to a predefined phone number.

To measure the speed we use a magnetic sensor ( Hall effect) on the bike frame and a magnet on the spook.

Depending on our speed a relay drives a servo motor which effects on speed mechanism.

## Step 3: Step 3: Writing Code

we wrote the code :

the code is divided in 3 parts

1. program for Edison Board to control all the peripherics
2. program for the smartphone to connect via bluetooth Edison board and server site
3. program server on the site connected with Microsoft Azure

## Step 4: Step 4: Test

The system is a prototype but was tested and is completely operative.

7. joystick
8. spbt switch
9. green LED
10. solar panel
11. 1 pb battery 12 V, 1200mAh
12. Internal gear hub Shimano Nexus inter 7
13. a smartphone

### Tools:

## Step 6: Step 6: Our Team

We are a great team. We have different skill. We love to use new technologies to change our everyday life.

We want a better life on a green planet!

Interesting, but ....
Not really the place ....
Thanks for the info.

I can't understand why do you think is not the place...

Thanks for showing us what you made. If you show us how we can make one that would be even more Instructable.

Sure, we are working to put all the passage to reply the system.
