Hammerhead - The Future of Bike GPS Navigation?

This unlikely looking gadget could be the future of Bike GPS Navigation. Hammerhead is used in conjunction with a Smartphone and displays turn information via a simple array of LEDs. The advantage this provides is that the smartphone can be stowed safely in the pocket with the screen turned off preserving battery life.  The unit is powered by a battery, chargeable through a micro USB port to provide around 20hrs operation between charges.  The Hammerhead also also doubles as a bike light for night visibility, incorporating a headlight and two side lights.  

Hammerhead is a crowd funded project, to find out more and back this project visit https://www.dragoninnovation.com/projects/23-hammerhead
