There are so many amazing gadgets that can be connected to your computer via Universal Serial Bus (USB) ports. One of them is the
Temperature@lert USB Sensor with Email Alerts. This gadget monitors the ambient temperature and will alert you via email if it falls below or climbs above a preset range. You can have Realtime graphing and XML support with temperature measures in both degrees Celsius or degrees Fahrenheit.
The device was primarily meant to be used as a alarm if the air conditioning in a server room failed. However, people have found out several creative uses for it. I was thinking of a crazy use for it. I drink a lot of coffee and have had my tongue burnt a few times. However, if you leave it to cool too long, it won't be tasty to drink. I was thinking that the 'Temperature@lert' would be a great way to test the temperature of the coffee in the cup everytime I want to drink it. However, I have to make sure that it is covered in a waterproof plastic bag and make sure that I have some tissue nearby.
