In the movie Wall-E, future humans live in floating chairs and have everything done for them. Today, we grumble if we have to go to physically find a light switch or a remote control. How far away can floating chairs with screens be? T2, the Tea Bot, gets us one step closer to that. Using a laser-cut frame, an ESP8266, and a servo motor, the T2 brews your tea for exactly the right amount of time.
We were kind of hoping the robot would at least dunk the tea bag in and out, but it does provide a web interface that lets you select the brew. Of course, the code is available, so you could make modifications — maybe turn on a hotplate underneath the cup.
Hardware modding can take you to some strange places: sometimes, you think of really useful improvements to your most practical devices. Other times, you turn a cup of tea into a theremin. This is true at least for [Kyle McDonald], who immersed the L/R leads of an 1/8″ cable in a cup of tea, and connected it to a computer running Max/MSP with a special patch. The result is a working, miniature theremin you can drink after you’re done playing. This process should work with any liquid, so feel free to use beer, cola, water, or anything you think will taste better after you’ve run a small charge through it.
