This is a small battery-powered thermometer that displays the temperature as a series of red and green flashes on an LED. by David Johnson-Davies:

The thermometer consists of an ATtiny10, a DS18B20 1-wire temperature sensor, and a bi-colour LED. To avoid the need for a digital display, and minimise current consumption, the thermometer pulses the temperature as a series of red or green flashes on the bi-colour LED. I designed it so I could seal it in a small waterproof enclosure and put it outside the window, allowing me to see the outdoor temperature from inside.

It incorporates several power-saving features to enable it to run for over a year on a CR2032 button cell.
