Brewing Tea Too Stressful? 3D Print A Tea Steeper

When you want to relax with a nice hot cup of tea, the last thing you need is the stress of dunking the teabag in and out of the hot water, right? [Andylear] got tired of it and he has a 3D printer, so he set about solving the problem.

The solution uses a standard mini servo and the VarSpeedServo Arduino library. This library uses interrupts to control speed and position of up to 8 servos. All servos can operate at once and you can control both the position of the servo and the speed of the motion required to get it there. Commands can be asynchronous or you can wait for them to complete and you can even send sequences of commands to each servo.

Steeping Tea Perfectly With An Arduino

While most of us here at Hack a Day can’t live without our daily java, we do understand and respect the tea drinking hackers out there, like [Brian McEvoy] the 24 Hour Engineer. Like any self-respecting hacker, [Brian] seeks to improve the efficiency of day-to-day tasks in order to spend his time on things that really matter — so he decided to automate his tea cup.

He’s 3D printed a small tea-bagging mechanism that a littleĀ RC servo motor can actuate, which allows him to control the amount of time a tea bag spends steeping in his mug. Another 3D printed enclosure includes the Arduino, a few buttons, and an LCD screen to allow you to select the steeping time for your favorite herb. In fact, the majority of this project is 3D printed which means the majority of the cost comes from the minimal electronics required — stuff you probably already have lying around. He’s also included all the design files you need in order to make your own.

The project has been in process for a while, but he’s finally finished it off, and it works great. If you’re hungry for some of the nitty-gritty build logs and troubleshooting a long the way, he’s got a whole bunch of blog posts from throughout the process.
