For many people the sound of a smoke alarm is so unpleasant that they’ll take the batteries out just to avoid it; for Jer Thorp, it’s a useful notifier whenever a key news story hits the wire.  Jer rigged up a smoke alarm to sound when a keyword-identified article appears, creating the incredibly annoying NewsAlarm.

Every week I seem to be writing about how someone has used an Arduino to fashion an interesting gadget, and today’s – while not as obviously useful as, say a Pong-playing wristwatch - is still impressive.  Using an Arduino, a Hall effect sensor and an electromagnet, the microprocessor board can keep a floating magnet perfectly positioned.

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.

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.

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.

Arduino have taken the tiny wraps off of the official ethernet shield for their open-source prototyping platform, which adds network connectivity to the device.  Based on the Wiznet W5100 ethernet chip, the new shield provides a network (IP) stack capable of both TCP and UDP, and supports up to four simultaneous socket connections.
