My Toaster Tweets
That statement sounds odd. Well, let me explain. My friends would describe me as the kind of person that has a lot of time on their hands. They would be right. That time is never put to productive use, but over Thanksgiving I got the gumption to start a new project. Sometimes, I start little servo, robotic, web-based projects for my own gratification, but I get fed up with all of the time I invest just so I can impress my 3 friends that also have nothing do to over the holidays.
My friend Jason Winters has been working on an module that simplifies the connecting of projects to the internet. He sent me one of his ioBridge modules to beta test and my mind started spinning. My goal this Thanksgiving was to think of a crazy project that would be the most senseless thing someone has ever heard of before.
Again, My Toaster Tweets…
Twitter is a social networking site that allows you to tell the world your current status – kind of like a microscopic blog that gets to the point. You can write, “Hans is going to lunch” or “Hans is tired”, etc. It’s fun to follow people and see what they can do creatively with just a few characters of updates.
I use my toaster when I am home and I thought that the world may want to know when I’m toasting.
How do you make a toaster twitter?
I grabbed my old bagel / toast toaster and glued a switch to the outside, so when the slider gets pressed down it triggers the switch and when it pops up, the switch opens (couldn’t be any more binary than that).
The ioBridge module has a digital input that I can hook the switch up to and monitor that state of toasting or not. Using a terminal board, a pull up resistor (1k), and some alligator clips, I hooked up the resistor from the digital input to the +5v source from the module, and clipped my clips on the resistor and the ground. A few pictures are worth more than my description.
Here is the whole system hooked together:
The Web Stuff
Using the ioBridge website, I created an event widget that monitors the input state of that particular digital input. And when the input is “high”, the site sends an HTTP POST to the ThingSpeak API to send a message to Twitter. ThingSpeak calls this “ThingTweet” and is one of many services that you can use to build Internet of Things projects.
