The Eugene Maker Space’s entry in the Red Bull Creation contest dispenses cans in a mysterious fog through an iris opening. But it’s also capable of disposing of the Red Bull cans… and only those cans. If you try to put a different soda in it will violently reject it!
First off we must applaud the Eugene Makers for their prolific documentation of the project. There’s a day or two worth of fun reading/watching on that page so make sure you save the bookmark (and learn from their example!). Inside the mysterious waist-high enclosure there’s a hopper to store the energy-drink reservoir. As a can is dispensed its barcode is scanned to ensure this is an approved beverage. At this point the can is elevated through an iris in the case of the enclosure, al0ng with a theatrically timed puff of fog. The parts of the iris were printed on paper and used to cut out wooden pieces using a scroll saw. The fog blast is from an inverted duster can with a 3d printed nozzle that helps make it Bullduino controlled.
When done with your beverage the can can be placed back in the opening, where it is again scanned before going into the recycling bin. But as you can see in the clip after the break, trying to sneak a soda can into the machine will launch the empty right back at you!

[Damcave] decided to try out some bar code reader projects. He got his hands on a CueCat years ago. The problem is that it outputs encrypted character sets instead of a clear text string. To get around this he used his Arduino to decrypt the CueCat’s data output.
Originally you could get you hands on a CueCat for free. It was meant to work like QR codes do now — you see a bar code, you scan it to get to a web address. It never really took off but you can still get your hands on one for about twelve clams. We’ve seen projects that clip a pin on the processor to disable to encryption. But [Damcave] didn’t want to mess with the hardware. Instead he connected the Arduino via the PS/2 connector and used software to translate the data. The encryption format has long been know so it was just a matter of translating the steps into an Arduino function.
Instead of building a $500 iPad into a cabinet [Gojimi] used the old hardware he had lying around to building this kitchen computer. He did buy a few items such as a used touchscreen and a bar code scanner but the 2 GHz computer was just collecting dust. It’s running Windows XP, talks to you like HAL or KITT, and scans the bar codes on food as you add it to the pantry or using it for meals. The lengthy video after the break covers all of the features, such as Weight Watcher’s calculations, food information, recipe book, unit converter, weather forecast, browser, and digital picture frame. It seems to have more features than the iPhone kitchen lookalike but it also looks dauntingly complicated. But we still want one.
