Unless you live in a special, unique place like Hawaii or Costa Rica it’s unlikely you’ll be able to surf every day. It’s not easy to plan surf sessions or even surf trips to most locations because the weather conditions will need to be just right. Not only the wave height (swell) but also the wind speed and direction, tide, water and air temperature, and even amount and type of marine life present can all impact your surf session. You’ll want something which can easily tell you right away if conditions are good.

This project from [luke] is called the Surf Window shows the surf conditions at the local beach with just one glance. Made out of various pieces of wood, each part represents one of the weather conditions at the beach. A rotating seagull gives the wind direction, for example, and the wave height is represented by 3D, moving waves. All of the parts are connected with various motors and linkages to an Arduino Mega +WiFi R3 which grabs all of its information from Magicseaweed, a surf forecasting site.

The Surf Window can show the current conditions at virtually any surfable beach in the world, so if you really want to know how Jaws, Mavericks, or even Reef Road is breaking right now, you could use this to give you a more nuanced look. Don’t forget to take the correct board for the conditions!

In 1994, Weezer famously said that “you take your car to work, I’ll take my board”. Obviously, for the office-bound, surfing is simply out of the question during the working day.  That doesn’t mean you can’t have a little fun with a desk toy inspired by the waves.

The crux of the build is a watery diorama, which interacts with a faux-surfboard. The diorama consists of a tank constructed out of plexiglas, sealed together to be watertight. It’s then filled with blue-dyed water, and topped off with baby oil. The tank is then mounted on a cam controlled by a servo, which rocks the tank back and forth to create waves. This is controlled by the motion of the rider on the plywood surfboard, which can be rocked to and fro on the floor thanks to its curved bottom. An Arduino built into the board monitors a three-axis accelerometer, and sends this information to the Arduino controlling the tank.

By riding the board, the user can shake the tank. Get the motion just right, and smooth rolling waves are your reward. Jerk around with no real rhythm, and you’ll just get messy surf. We reckon it would be even better with a little surfer floating in the tank, too. It’s a fun build, and one that might help stave off the negative health effects of sitting at a desk all day. You might prefer a more shocking desk toy, however. Video after the break.
