Free Fresh Article: Thermoelectric Tea Timer
With the compliments of the Elektor Labs and Editorial teams, here comes another previously unpublished article that's free to download by all registered Elektor e-zine readers. "Free Fresh Articles" are published at two-weekly intervals in the Elektor e-zine, alternating with "Free Back Articles".

This time we have a contraption that automatically lifts a tea bag from a cup or glass of hot water after a preset time. It employs energy harvesting meaning the circuit works off the heat energy taken from the hot cup.
And yes it contains a microcontroller, this time the extremely accessible ATmega169PA, with an LC display as a peripheral.

Put on the kettle and while you wait, go to the free article here. Enjoy your cuppa!
