#339: Thermalarm

People living in a climate involving sudden drops to sub-zero temperatures overnight know the annoyance which having to scrape ice from their vehicle causes.

It’s especially true if you have a demanding early morning schedule to meet.


Today’s invention is an alarm clock with a thermouple attached. This detects freezing temperatures outside and automatically adjusts the alarm sound to occur a few minutes earlier than normal getting-up time.

It might even change the indicated time in order to encourage a more urgent start to the day -and the windshield scraping.
