This USB Thermometer is pretty cool. It will let you be your own amateur indoor meteorologist (if you’re reading this Al Roker, don’t worry your job is still secure) because the device not only takes the curremt temperature, it also captures and logs it at whatever interval you want- from every second to 12 hours. You can then easily copy and paste the data into a spreadsheet for analysis and to impress your weather geek friends. This would actually be handy to learn what the temperature of your home or office is when you’re not there. Costs $20.
