Twitter Radio

This anthropomorphized wood bowl will read Tweets out loud. It was built by [William Lindmeier] as part of his graduate work in the Interactive Telecommunications Program (ITP) at New York University. View the clip after the break to see and hear a list from his Twitter feed read in rather pleasant text-to-speech voices.

The electronics involved are rather convoluted. Inside the upturned bowl you’ll find both an Arduino and a Raspberry Pi. But that’s not the only thing that goes into this. The best sounding text-to-speech program [William] could find was for OSX, so there is a remote computer involved as well. But we think what makes this special is the concept and execution, not the level of hardware inefficiency.

The knob to the left sets the volume and is also responsible for powering down the device. The knob of the right lets you select from various Twitter lists. Each turn of the knob is responded to with a different LED color in the nose and a spoken menu label. You can get a quick overview of the project from this summary post.

Twittertape Machine Keeps Track Of Your Social Media Stock.

March 17, 2012 by 13 Comments

During the gilded age, oil magnates, entrepreneurs, and robber barons would have a ticker tape machine in their study. This machine would print stock and commodity prices and chart these men’s assets climbing higher and higher. A lot has changed in 100 years, as now [Adam] can be kept apprised of what @KimKardashian, @BarackObama and @stephenfry ate for breakfast with his Twittertape machine.

Interestingly, [Adam]’s build didn’t start off as a tarnished lump of 100-year-old brass; he built his beautiful ticker machine out of old clock movements he picked up on eBay. Even though the shiny part of the build only holds the roll of paper, it’s still a wonderful build. Right now the machine is connected to Ethernet, but he’s planning on adding WiFi and a few batteries for a completely wireless build.

Unlike the other ticker tape machine we saw this week, [Adam] did away with the loud clashing of gears and solenoids found in 100-year-old ticker machines. This ticker machine prints on cash register receipt paper and a very small thermal printer in the base. Although [Adam]’s build doesn’t sound like two robots trading blows, there’s no ink needed and no danger of the letter wheel becoming misaligned and misspelling everything.

Check out [Adam]’s build in action after the break.

Display Twitter On An Arduino

February 27, 2012 by 14 Comments

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.

Telegraph Key Makes For A Fantastic Twitter Input

January 31, 2012 by 21 Comments

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.

@publictextbox Is A Twitter Enabled Phone Booth

January 27, 2012 by 7 Comments

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.

Twitter-enabled Candy Machine Dispenses Treats On Command

December 15, 2011 by 4 Comments

[Michael Nilsson] and [Markus Olsson] were contemplating how to motivate members of their dev team when they came up with the idea of a candy machine that automatically dispenses treats when someone has earned it.

They picked up a candy machine, a continuous rotation servo and a controller, then got busy automating the dispenser. The mechanism behind the operation is actually pretty simple as you can see in [Michael’s] writeup. They disassembled the machine, removing the gear from the manual crank, attaching it to the servo. Once the servo was mounted place, they installed the servo controller and connected it up to a spare laptop.

The heavy lifting is done by a Ruby script that uses the Twitter API to scrape any mentions of @_macke_ or @sidpiraya. Incoming messages are checked for the words “give” and “candy”, triggering the machine to fork out some sweets.

If you think that their hard work deserves a bit of recognition, feel free to send them some candy by tweeting “give @_macke_candy” or “give @Sidpiraya candy”. Just remember to be considerate – nobody likes spam, not even candy machines!

If you’re interested in seeing the machine in action, be sure to check out the candy dispenser’s live stream at giveawaycandy.com.

Beer Dispenser Talks To Customers, Announces Office Parties Via Twitter

November 25, 2011 by 15 Comments

Just about the only thing better than beer is free beer.

Staff at the Arnold Worldwide ad agency are free to imbibe in the office’s lounge area, but a few employees thought that it would be pretty awesome to have their beer stash offered up by a vending machine. Using a grant that the company sets aside for “creative projects”, they built [Arnie], the interactive beer dispensing machine.

The machine was stocked with company-branded brews, and each employee carries an RFID key fob pre-loaded with beer credits. When the urge hits, staff members swipe their fob in front of the machine and select their preferred drink from the large, front-mounted touch screen. [Arnie] speaks with his customers and also uses Twitter to announce parties in the making, when a handful of bottles have been vended over a short period of time.

The project was a great use of money if you ask us, and we think that every office should have one of these babies in-house.

Continue reading to see a short video of how [Arnie] came to be.
