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.

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.
