So this is a pretty neat idea: An aluminum cube that gives you the physical sensation of tomorrow’s forecasted temperature. It’s called the Cryoscope, and it’s the Arduino-powered creation of Robb Godshaw. The idea is that instead of just looking at the weather forecast, you can put your hand on the cube and actually feel the air temperature thanks to the device’s internal heat pump. It’s clever, though one wonders how it would handle extreme temperatures. Perhaps if you saw frost forming on your Cryoscope, you’d know that it’s best to stay inside. See Godshaw’s explanatory video, after the break.
