This isn’t a thrift-store coffee table modified as a craft project. [Dandujmich] built it from the ground-up using framing lumber, bottle caps, plastic resin, and some electronics for bling.
The first step was to see if he had enough caps on hand for the project. It’s hard to grasp how many were used just by looking at it, but the gallery description tells us there’s about 1700 which went into the design! From there he grabbed some 2x4s and began construction. The table legs started with two end assemblies built by doweling the legs to the end cross pieces. From there he cut a rabbit on the side rails and screwed them to the leg assemblies from the inside.
The tabletop includes a frame with a recessed area deep enough to keep the caps below the surface. After spending about ten hours super gluing all of the caps in place he mixed and poured two gallons of the resin to arrive at a glass-like finish. The final touch is some custom hardware which pulses two rows of embedded LEDs to music being played in the room. The video after the break isn’t fantastic, but it gives you some idea of how that light rig works.

The Cool Master is a beer delivery system which Innovation Thirst built as their qualifying entry for this year’s Red Bull Creation contest. It’s one of the best beer delivery concepts we’ve ever seen. Instead of tossing you a beer directly from the fridge, this offering brings the cold beverages directly to you. It even manages to de-cap the bottles before serving.
Mobility is provided by a six-wheeled base which allows for a zero-turn radius. The cooler acts as the body of the robot, and hides a hopper which carries a stock of bottles on their sides. When you want a beer, the bot approaches you, tilts the next bottle to the upright position, removes the cap, then raises the vessel on a beer elevator until it pushes its way through the rubber orifice in the cooler’s lid. Right now the device is operated using an RC controller, but there’s always room for adding autonomy and the ability to restock from a refrigerator. Don’t miss the demo video after the break.

The Klackerlaken is a combination of LED throwie and bristlebot. The bauble is easy to build and really has no other purpose than to delight the masses. The diminutive devices were first seen in the wild at the 2011 CCC (Chaos Communications Camp) as a hands-on workshop. Check out the clip after the break and you’ll see why this really sucks in the spectators.
We’ve seen a ton of Bristlebots before (this tiny steerable version is one of our favorites) and were intrigued to see bottle caps used as the feet instead of the traditional toothbrush head. In fact, that video clip shows off several different iterations including two caps acting as an enclosure for the button cell and vibrating motor. Googly eyes on the top really complete the look on that one.
Decorating the robots with LEDs, fake eyes, tails, and feathers helps to temper the technical aspects that kids are learning as they put together one of their own. We’re glad that [Martin] shared the link at the top which covers the creations seen at a workshop held by Dorkbot Berlin. This would be a great activity for your Hackerspace’s next open house! Perhaps its possible to have follow-up classes that improve on the design, using rechargeable cells instead of disposable buttons, or maybe supercaps would work.
