FOSDEM-85 as a desk thermometer
Vote
The ATTiny85 internal chip sensor of the FOSDEM-85-penguin is used for measuring the room temperature. The two eye-leds display the temperature with a blink code. Therefore the green power led is cut from VCC and soldered to PB2 data pin.
The penguin is powered by a CR2032 cell and so all is done to reduce the power consumption.
