Google Software Engineer Invents Gadget That Reproduces Weather Conditions In Living Room

By: Vandita via

Japanese Google software engineer Ken Kawamoto has invented Tempescope, a transparent box-type gadget that collects next day’s forecast from online weather sources using two pumps, an ultrasound diffuser, and an LED to simulate a variety of weather conditions – from sunrise, sunshine, and sunset to clouds, lightning, rain and fog – inside your living room hour-by-hour.

Kawamoto explains the mechanics:

For rain, water pump pushes water from the lower chamber to the upper chamber, allowing water to fall through holes drilled at the bottom of the chamber. To simulate clouds, the ultrasound diffuser in the lower chamber turns on, creating mist.  An external air pump pushes air (and mist) up from the lower chamber into the cylinder stage. For lightning, the full-color LED is turned on at random intervals. For bright sunlight, the full-color LED changes color from off to red to blueish white, depending on the time of day.


When Kawamoto created the prototype in 2012 to ‘break the barrier between the digital world and the real world’, the Tempescope was controlled by a small Arduino board linked to a PC via USB or Bluetooth. Earlier, the gadget had two modes of operation, both of which ran as PC programs – “Tomorrow’s weather”, which animated tomorrow’s weather forecast, and “World weather”, which reproduced the current weather of any location in the world.

Today, the Tempescope connects to the Internet via an app downloaded on a Smartphone, comes with a SD card so forecast sequences can be saved and replayed without the device being attached to a PC, and has several modes of operation such as “Weather forecast mode”, which can show today’s weather forecast during the day, or tomorrow’s forecast in the evening, and “Manual mode”, which can force the Tempescope to show a particular weather, or define an animation sequence to play.

thx for the sudden revived interest in the tempescope- unfortunately we have no production plans for the time being.

If you’re desperate, you can always build an OpenTempescope, our open source version!

Kawamoto – who is now working on making extensions, such as snow, wind, real lightning bolts and showing land features but has no plans yet to start production – has released the code, instructions, and schematics for the Tempescope to allow anyone to comfortably build their very own transparent acrylic box to recreate the meteorological conditions in their living room.
