Robot fish reads your tweets; new mbed microcontroller [Video]

Robot fish reads your tweets; new mbed microcontroller [Video]

Is there any better hack than making a robot fish read out Twitter messages?  If there is, don't tell Dan Ros about it: he's spent his spare time hooking up a Big Mouth Billy Bass "novelty" fish to an mbed microcontroller.  Initially the fish merely repeated .wav files from an SD card, but then they used the mbed's HTTPClient library to pull in tweets instead.

Arduino wristwatch plays Pong

Arduino wristwatch plays Pong

One of the reasons the Arduino is so successful is because of its flexibility - there's plenty of very complex ways you can implement the microprocessor board into a project - but that doesn't mean it can't do simple tasks just as well.  Psycholinguist Franklin Chang used his Arduino to make a fetchingly homespun wristwatch.

Twitter Burglar Alarm tweets to let you know your TV is being stolen

Twitter Burglar Alarm tweets to let you know your TV is being stolen

I'm more used to Twitter trying to steal my time and concentration, but this latest Arduino project turns it into a protector of law and order instead.  The Arduino is used to monitor a home burglar alarm and send out status messages should anything unexpected happen; that could include when the alarm was activated or shut off, error messages regarding dodgy sensors, or just when the alarm actually sounds.

DIY Arduino control box with computer monitoring

Arduino-fanciers Oomlout have put together a neat control box for the popular prototyping board, complete with five potentiometers and three switches.  There's also a software app that can monitor the position of each of the controls.  In the process, Oomlout have (hopefully) tipped that their next product may just be an Arduino-controlled robot arm.

Check out the demo video of the control box in action, after the cut
