The BakerTweet Box sends updates on every fresh tray of cakes and pastries as they come out of the oven, so you'll know when to time your visit to the bakery. Proving once again that necessity is the mother of invention, the team at POKE's London office built BakerTweet for the Albion, their favorite bakery across the road from the office.

Everyone knows the best time to get your baked goods is when they're fresh out the oven. So we figured that this could be a killer use of Twitter. Letting followers know that fresh goodies are ready right now. But bakeries don't want laptops or phones lying around in the kitchen. Flour, eggs and technology don't mix so well.

The prototype was built using open-source electronics platform Arduino and the interaction is minimal, to send a message to local customers following the twiiter feed, you turn the dial to select what's just been baked and press the button. Simple. POKE will publish a 'how-to' in the next days if you want to make one. Given the popularity of the Tweet-a-Watt in the recent Greener Gadgets competition, we're sure there's going to be a lot more single-purpose twitter powered devices in the coming year.
