If you are a surfer who can’t check the swell just by looking out a window, chances are you use sites like Magic Seaweed to get your info. The Surf Indicating Lamp by Max Ashford takes the surf report out of your phone and puts it on your nightstand. From the project description:
I created a lamp that represents what the local surf conditions are. I did this using data from magic seaweed; a surf forecasting website, this input was then programmed to a light output using the Arduino Leonardo unit and two RGB LED’s. I used processing to run the code.
