Applications and Implications

Bike Navigation System

 

Fab Academy 2019 - Gustavo Abreu

What will it do?

In the simplest and less distracting way as possible, display where and when a cyclist needs to turn in order to get from point A to point B in a city.

week06 iteration - 3D printed case with a 16x2 display + arduino

Why not to use a smartphone or GPS?

Who’s done what beforehand?

Launched a kickstarter campaign in 2015. Pledged $538.000 out of  $67.000 they asked. It has been on the market ever since.

Launched a kickstarter campaign in 2015 as well. Pledged £150,000 out of  £60,000 they asked.

What will you design?

Electronics

Enclosure

Handlebar Mount

iOS Application

What materials and components will be used?

Enclosure:

3D print plastic filament  
Acrylic  
Rubber O-ring or gasket

Electronics:

Microprocessor  
Display  
Bluetooth module  
Accelerometer  
Battery charger  
Battery

Where will it come from?

How much will they cost?

Component Cost
3D print €10.00
Acrylic piece €2.00
Copper board €3.00
MCU €5.00
Display €6.00
BLE €10.00
Battery charger €3.00
Battery €5.00
Other components €5.00
Total €49.00

What parts and systems will be made?

A water resistant enclosure with a handlebar mount.


A board with MCU, Display, BLE, IMU and battery charger.


An iOS application for the user to interface with the device.

 

What processes will be used?

Electronics production

Eagle

MODS

Milling

Soldering

Board programming

Arduino IDE

Libraries

C

Low power mode

Enclosure and mount

Import board from Eagle

Design in Fusion 360

Slice

3D Print

iOS App development

Xcode

Swift

Mapbox SDK

Faith

How will everything work?

iOS App

Update next turn

What questions need to be answered?

How much time should I invest in the water resistant enclosure right now? Is it even necessary for the prototype?

How to manage data transferred trough bluetooth?

Should the device be difficult or easy to remove from the bike?

If it stays on the bike, how long should the battery last?

Does it make sense to further develop the project as an open source solution?

How will it be evaluated?

Getting from point A to point B using the device, without knowing the route beforehand, is already a huge win.
