Barista Bots, one of the most popular attractions at this year's South by Southwest festival in Austin, printed scanned logos, smileys and other shapes atop comped lattes. Thirsty attendees with 20 minutes to spare for the queue walked away with a free coffee and a robot-extruded froth. The novelty will have surely worn off by next year's SXSW, and we think we've stumbled upon the perfect replacement. It was born from a desire to turn otherwise ordinary gelatin shots into an original alcoholic treat -- meet the 3D Jello Printer.

SpritesMods managed to accomplish this feat with a lot of creativity and a few recycled parts. They repurposed the stepper motors from discarded CD-ROM drives to move a syringe along the necessary axes, and used an old ejector mechanism to push down the plunger. An AVR microcontroller stores several different designs, which materialize in tiny jello shots using a cocktail of banana liquor, food coloring and a bit of corn starch to turn the liquid into a gel. SpritesMods is kind enough to help you get started with creating your own. Just dig up some choice e-waste and follow the tutorial -- you'll be mass producing the perfect New Year's Eve consumable in no time.
