If you ever wanted your name out on the Internet, now is your time to shine. [Chris] hooked up an Arduino to the Internet and is streaming the results of combing through Twitter live to the entire world.
The SocialBot9000, as [Chris] calls his build, is an Arduino Uno connected to an Ethernet shield and an LCD character display. The firmware uses the Twitter API to search for recent posts containing the phrase, ‘socialbot9000.’ A PHP script on the Arduino does all the heavy lifting and with the great Bildr tutorial on getting the Ethernet shield up and running, [Chris] was off to the races.
Because it’s extremely doubtful that everyone on the Internet could manage typing a message into Twitter that would be correctly parsed by the SocialBot9000, [Chris] put a small form up on the build log that will correctly generate the message and take you to your Twitter account for posting. After all that was done, [Chris] decided to have some fun and set up a live feed from a camera in front of the LCD display for the world to watch.
Wii Nunchuk controlled Monotron
Adding a bit of motion control to your music synthesizer turns out to be pretty easy. Here’s an example of a Wii Nunchuk used to control a Monotron. [Thanks John]
Hackers on the Moon and other space related goals
Yep apparently a non-government backed expedition to the moon is in the works. But you’ve got to walk before you can crawl and one of the first parts of the process is to launch a hackerspace-backed satellite network called the Hackerspace Global Grid. Check out this interview with one of the initiative’s founders [Hadez]. [Thanks MS3FGX]
Laser pointers and frosted glass
We were under the impression that a laser show required finely calibrated hardware. But [Jas Strong] proves us wrong by making pretty colors with laser pointers and slowly rotating glass. [Thanks Mike]
MSP430 Twitter Ticker
[Matt] built a Twitter ticker using the TI Launchpad. It works on an LED matrix or OLED display along with a Python script which handles the API.
Android floppy drive hack
[Pedro] shows us how he reads floppy disks with his Android tablet. The hardware includes a docking station to add a USB port to the tablet, as well as a hub and USB floppy drive. On the software side of things an Android port of DOSbox does the rest.
Members from the London Hackerspace recently got a little on-air time with a ping pong ball launcher. They were invited to build something for the Click show on BBC. The launcher that they built responds to hash tags on Twitter by barraging the audience with balls.
The hardware was built in two parts. The first is a dispenser that responds to incoming Tweets by releasing one ball onto a set of staging ramps. The other portion is the launcher itself. Building it like this makes it a rapid fire device, as the spinning wheels of the launcher make quick work of several dozen balls just waiting to be let loose. Check out some footage from the show after the jump.
We like this one just as much as that remote controlled launcher. We’re glad to have seen these both because we happen to have a surplus of the balls lying around since we built that clock and we’re not about to undertake some of the more dangerous ping pong based projects we’ve seen.

In the interests of interface archaeology, [Martin] sent in the Tworse Key, a telegraph key that posts to Twitter using Morse code. It’s a fantastic build that nearly looks like something out of the 1900s.
We’ve seen a ton of Morse keyboards over the years, but never one so well-engineered for a single purpose. The guts and brains of the Tworse Key is an Arduino Ethernet that connect to Twitter over the API. The Tworse Key automagically posts all the Morse messages to Twitter. The Tworse Key may have fallen off the table a few times in the past 24 hours, but we do see a few purposeful messages like ‘sos’ and [Bell]’s preferred telephone salutation.
We could say that nobody uses straight telegraph keys anymore, but outside a few hardcore CW HAM radio guys nobody uses Morse anymore. This isn’t meant to be used as an everyday input device, though. It’s more of an exercise in interface archaeology. That being said, an iambic key would be a far more ergonomic solution. Check out the video of the Tworse Key after the break.

In the interests of open communication in shared spaces, [dan] made a public text box that serves as a terminal to the @publictextbox twitter account. We could see something like this being useful in a hackerspace or other hang out to announce to the world the happenings of the resident makers and builders.
The software setup is very simple and can run on just about any old computer you might have lying disused in a corner. The app is built with Processing, and the code is extremely simple and easily modifiable. Even though the case is a lovely cardboard number, the Twitter Box can be dressed up as any imaginable form. We’d love to see a nice TARDIS blue, but we’ll leave that up to [dan].
You can check out the demo of the Twitter phone box after the break. Alternatively, you could re-tweet this post and take part in a load test for the @publictextbox.

[Axel] wanted to participate in the CheerLights project this holiday season, but not one to always follow the rules he decided to make his display a bit different than most others out there. While the lights at his house are synchronized with the CheerLights project, he programmed his Cheeriobot with a little added personality.
Normally, Cheeriobot is happy to follow the rest of the world, changing its colors whenever the Twitter feed dictates. If things are a bit slow however, Cheeriobot gets impatient and will send a tweet to @CheerLights on its own to ensure that it doesn’t display a single color for too long.
[Axel] also created a mode that turns Cheeriobot into a bit of a contrarian. The display’s “Rebel Mode” causes it to change colors when someone tweets, but it selects a random color instead of following the rest of the pack.
It’s definitely an interesting twist on the CheerLights project, and we really like the fact that it keeps things moving if the stream of tweets ever slows down.
They say that the holidays are a time to gather with others, which usually translates into spending time with friends and family. The folks at ioBridge Labs thought that while friends and family certainly are a big part of the holidays, it would be pretty cool to gather together flocks of strangers by using the Internet to synchronize their Christmas lights.
Participation in CheerLights is pretty easy, requiring little more than an Internet connection, some GE G-35 Color Effects lights, an Arduino, and an ioBridge. While those are the recommended components, an Arduino Ethernet shield will handle networking just as well. There really are no restrictions when it comes to hardware, so if you are so inclined, it should be relatively easy to roll your own display using simple RGB LEDs and a µC of your choosing.
The colors are dictated by the group’s Twitter feed, which can be found at http://twitter.com/#!/@cheerlights. Whenever a message is sent to @cheerlights along with a color, all of the light displays listening in will change simultaneously.
We really like the idea, and think it would be pretty cool to see this sort of program rolled out on a neighborhood or street-wide level, so you could see dozens of strings changing colors all at once.
If you’re interested in checking out CheerLights’ current color, be sure to take a gander at their live stream here.
