For when you’ve had enough of the weatherman, which is like, always. The Tempescope is a cool invention that lets you know of tomorrow’s weather forecast by actually simulating sunshine, rain, fog, and even lightning indoors. Created by Japanese designer Ken Kawamoto, the device features a small box that gathers weather information online and then simulates that forecast using a combination of LED light, water, and ultrasonics (for the fog). Great if you’re too lazy to get up off the couch and look out the window. DIY experts can help themselves to Kawamoto’s open source version for the Tempescopeby accessing it at ‘OpenTempescope’. Others will have to wait a bit longer as the Tempescope team is still getting ready to launch a Kickstarter campaign later this year.
