If you are a big tea fan, you already know why I built this!
Sometimes you just forget the tea infuser into the cup...
If you are lucky, the tea tastes just a bit strong, but for the worst cases, it becomes undrinkable.
This situation occurred too often with me, so I was eager to find a solution.
One weekend I built this odd looking machine that solved my problem.
Fast, easy and intuitive user interface based on a rotary encoder
Can be used as a generic kitchen timer
USB configurable tea database
Plays a tune when countdown is zero
Automatic sleep mode, low idle power consumption
Built with easily accessible off-the-shelf components:
Arduino (ATmega328P)
Stepper motor
2x16 character LCD display
Rotary encoder
Piezo loudspeaker
