Before we begin, let us soothe those first dreaded thoughts. No, the commodore was not destroyed in the process. They can simply clip the 16 wires they added to interface the keyboard and be back to stock. Breathe a sigh of relief, and enjoy the twypper, a twitter wall made from a commodore SQ1000.

[Alex] needed to make an interesting project for his companies Openspace/hack day. A friend, suggested a twitter wall, and that’s when [Alex] got the idea for a typewriter. After a quick search, he found oomlaut’s typewriter. They didn’t let that deter them from making their own version though. They found a nice fully functional commodore SQ1000 and began hacking. Ultimately they simply decided to use an Arduino to short the key switches to simulate typing. There are all kinds of details on the necessary steps to get the typing to function absolutely correct on the project page. Over all it was well done and we’re happy to see that it can be undone just as easily.

Twitter, Talking Fish, And More

[Dan Ros] and the mbed team sent in their hack of a twitter talking Big Mouth Billy Bass. Originally the hack simply had an mbed micrcontroller and an SD card with some wav files allowing Billy to say classic quotes. Wanting to go further however, they used the mbed’s HTTPClient library to grab Twitter updates, and then have Billy say them out loud! Check out some other cool projects the mbed team has in the cookbook.

But wait, whats an mbed? We didn’t have a clue either!

Some researched reveals it is a powerful new microcontroller and prototyping board. With some features such as direct ethernet and USB connections right on the chip, as well as PWM, serial, analog, and more. What really stoked us is how it acts much like a USB thumb drive. Drag and drop your binary files, and it’s programmed! The only downside, at $100 it can be a bit more of an investment compared to an Arduino PIC. Could this be the next big prototyping tool that beats all others? Lets hear it in the comments!

[Update: The mbed can be had for a limited time pre-order price of $60 not $100 – Thanks Dan and the mbed team!]

Tweetidor, The Tweeting Humidor

September 21, 2009 by Matt Schulz 20 Comments

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.

SparkFun Kegerator Goes To Eleven

September 10, 2009 by Phil Burgess 19 Comments

It started with a simple need: keep tabs on SparkFun Electronics’ in-house kegerator so the beer won’t run out at inopportune times. But of course SparkFun and “simple need” make strange bedfellows…throw beer in the mix, and you know this can’t end well. The result, as you might imagine, reads like a who’s-who of electronics hackery buzzwords.

Arduino? Check. Custom PCB? Check. Web interface? Check. Twitter feed? Check.

They’ve assembled a nice build tutorial on how this all went together, including code, example circuits, an explanation of some of the sensors used, and links to other tutorials for such things as Twittering and persistent storage in EEPROM using Arduino. Not to mention the eye candy: a custom Arduino shield (solder mask and all), custom acrylic tap handle, custom SparkFun pint glasses. They never do anything halfway, do they?

Build Your Own Browser Extensions For Google Chrome

September 8, 2009 by Mike Szczys 6 Comments

[Ryan] posted a writeup on developing extensions for Google Chrome. The extension system utilizes HTML with a JavaScript API which is still sparsely documented. After taking us through his twitter bar extension project, he concludes that the Chrome extensions are not nearly as versatile as what we’re used to seeing with Firefox. That being said, this is a move in the right direction for the young browser.

Twitter Remote Control

September 2, 2009 by Jake W 16 Comments

We’ve already brought you a homemade Twitter-enabled washing machine, and toilet, but now a new innovation is being brought to the table by a bigger player. IBM is working on a tweeting television remote, which would allow the user to inform the world what they are watching. Although unfiltered reporting could create awkward situations, the combination of America’s love for television and Twitter is sure to yield interesting results. They also mentioned that it could be configured to report to other sites, such as Facebook or joost. Any ideas why IBM would have in such a patent are welcome in the comments. More info can be found here and here.

Twitter As A Botnet Command Center

August 26, 2009 by Matt Schulz 7 Comments

The folks over at Arbor Networks were browsing Twitter and discovered something very strange: a Twitter account seemingly posting gibberish. At least, that’s how it appeared at first. Upon closer investigation, they discovered that the profile was posting base64 encoded links to PKZIP archives. When they extracted the contents and unpacked the contained DLL and EXE files, they discovered that the account was posing links to malware that would post user information back to certain URLs. The article was also updated to show that the scheme wasn’t limited to Twitter, but also affected users on Jaiku and Tumblr. It’s a bit scary to see that all malware isn’t as blatantly obvious as we usually would think it to be.
