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?

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?

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