PC Thermometer

This incredibly simple thermometer plugs on any free serial port. Does not make use of any programmable components as microcontrollers. It gives temperature readings accurate to 0.5°C with no calibration. It’s cheap, so I’ve put one on any PC I use. And it’s soooo nice to have the temperature shown on the Windows taskbar, that a million friends asked me to build one!
