Dynamo Bike Light

A rear LED bike light that is powered directly from a dynamo on the back wheel. It was created as a product design project where the aim was to create a sustainable lighting solution.

All materials (excluding hot glue and solder) used to create it were recycled or reused. Many of the electronic elements came from either broken appliances or a R/C car, the metal brackets holding the dynamo in place were created from a tin can, and the plastic shell of the light was the packaging for some epoxy putty.

Here are some screenshots of the design process:

The finished light and dynamo fits on as shown in the images above. It functions very well and gets even brighter when going fast, although still glows enough to be seen when traveling slowly.
