Watch-a got for today’s weather forecast? 


The Weather Watch monitors air pressure and temperature to provide its wearer with the forecast. 


If you want to know the weather, but care more about geeky style than accuracy, this wrist-mounted watch might be a good project for you. As creator “AgentMess” puts it, “It is obvious that the device cannot obtain the accuracy of established forecast services, but what it lacks in precision it makes up for in style.” He also notes that if you’re not interested in its weather prediction capabilities, “You can use it when you are going for a walk at night to be seen by cars and other road users.”

The display is made using a 16 x 8 LED matrix with a “backpack” to control the display, and its “predictive power” is accomplished using an Adafruit FLORA (ATmega32U4) with a GPS module and barometric pressure sensor. The idea is that the air pressure outside can be used to roughly predict upcoming weather. Since air pressure varies by altitude, the GPS module is employed to compensate for pressure changes due to movement.

As you might suspect, the accuracy of this gadget can be thrown off when indoors, but hopefully its not as important there anyway. Of course, there are all kinds of other things one could do with a GPS-enabled wrist display. This project, though very cool in its current form, is just begging for improvement. If you have any ideas, the original Maker invites you to leave them in his original article!
