A fresh pot of coffee is never more than a tweet away with the Tweet-a-Pot. It works in much the same way that our Troll Sniffing Rat does. For that build we used a Python script to monitor our comments, and this does the same except that the script read tweets through the Twitter API. It watches for a specific hash tag (#driptwit) and when found it sends a serial command to an Arduino. The microcontroller then writes a digital pin high to actuate a relay, powering up the coffee maker.
Sure, you have to preload the pot with grounds and water, but what do you expect, automatic coffee roasting and brewing? That’s quite a bit more work.
Being avid fanatics of flashing lights, we always love to see the peggy2 in action. The video above shows another improvement, which is two peggy2 units working together as one. [iservice2000] chained the two together and wrote new code for the display. Using an Arduino to drive it all, he has gotten them to act as one. While video on the peggy2 isn’t new, this is the first time we’ve seen two of them chained together. The end result is going to be a scrolling sign that can be updated via the web, or that can display tweets. We did notice a bit of tearing, is that from the camera or the software?
As cigar aficionados will tell you, cigars should be stored in climate controlled humidors to keep them in best condition for smoking. Most of the time a humidor is just a simple air-tight box with a hygrometer attached, which measures the relative humidity inside the box. Feeling as though he needed more control over the environment he kept his cigars in, [Justin] created the Tweetidor, a humidor that tweets its current temperature and humidity. Yes, you guessed it; the project is built around an Arduino. It’s a simple, useful project that is well documented and would be fun to recreate if you’re into cigars (and not tired of Twitter or Arduinos yet.) Combine this with the laser lighter and you’ve got a pretty nice setup.
