The Freddie Mercury Thermometer

Saturday 9th May 2012

The Freddie Mercury Thermometer uses the Queen singer's voice to tell us the temperature.

Video

In the video I demonstrate the thermometer, showing the different sounds it makes depending how hot or cold it is. You turn it on and place the sensor wherever you want. Press the button, and you find out the temperature by the sound of Freddie's singing.

Details

The hardware consists of a Raspberry Pi, a digital thermometer chip, a push button and a powered speaker. The Pi is running the standard build of Raspbian, a bunch of audio clips of Freddie Mercury with Queen live at Wembley in 1986 and a script I wrote in python to read the temperature.

Why?

I made this for 3 reasons:
