Fancy beer pong table cleans your balls

Beer Pong seems to have been around for some time but it only recently exploded in to a universally known game. But one thing has always bothered us. Who wants to drink the beer into which that grimy little ball has fallen? Leave it to the frat boys at MIT to come up with a solution. Their beer pong table automatically cleans your balls.

Of course the table looks great. It’s outfitted with laser cut felt lettering on the apron, and the top features EL wire highlights. But the two features that really set it apart aren’t hard to spot either. First, there are rain gutters along either side to help catch the spillage. Secondly, that blue ring is actually the input nozzle for the ball cleaner. By pushing the ball through the vinyl sleeve it enters a recirculating liquid cleanser, popping out of the portal on the left a second later. That’s about all the details we have on the system, but you can get a closer look at the inner workings in the clip after the break.

The thing to remember is that these guys NEVER run out of ping-pong balls. They’ve got thousands on hand ever since they built this launcher.

Interactive table is slightly different than most.

[DanNixon] has put together this unique interactive table concept. Usually, when we see the term interactive table, we think of an LED grid. That just happens to be what we see the most of. While this table does, in fact, have an LED grid in the table top, it also has several other features and some very nice construction.

Instead of going the usual boring rectangular route, [DanNixon] decided to build a more visually appealing structure. The build log on that part alone is worth a peek. After that, he has a small LCD screen for displaying headlines and song titles as well as a compact LED matrix for some visualizations.

Great Job [DanNixon]

This LED table really ties the room together

led-matrix-table

Along with quadrotors, and portable game consoles, one of the hacks we never get tired of seeing is an LED matrix table. [Christian Enchelmaier] wrote in to share his take on the ever popular pixelated furniture, which we think came out pretty well (Translation).

Instead of going for a full-sized coffee table, [Christian] decided to keep things on the smaller scale his first time out, opting for an ottoman/end table nstead. He constructed a 16×16 matrix using RGB LEDs, encapsulating each one in its own “pixel”, as is common with these builds. [Christian] uses an Atmega 128 to run the show, displaying the current time and date, temperature, music visualizations, games, images, along with short videos. He also outfitted the table with an IR receiver so that he can control the table’s display from afar.

As of right now, [Christian] doesn’t have any video of the table in action, but there’s plenty in the way of pictures scattered throughout his build log to keep you busy in the meantime.

Digital gaming table made with no smoke, just a mirror

The concept of having a digital gaming table got stuck in [RobotGuy's] mind over the weekend and he managed to whip this up in no time using materials on hand. He already had a ceiling-mounted projector which just happens to reside immediately above the space occupied by his coffee table. By swapping that piece of furniture out for a white Ikea table, and adding a mirror to the projector he now has the virtual gaming surface he was looking for. The mirror mount is nothing more than a desk lamp that includes a spring clamp and flexible neck. He hot glued the piece of mirror to this, and attached it to the projector’s ceiling anchor. Since rear-projection screens are common, all digital projectors have the ability to mirror and rotate the image being displayed so that it appears on the table in the correct orientation.

We love the look, but this is really only one portion of a digital gaming project. We think the table needs some interactivity. We often see this done using infrared light processed by a webcam. That multi-touch option is not going to work with a standard table since the camera needs to be on the opposite side of a translucent surface. But if you don’t mind using a stylus this IR whiteboard technique would work.

Building your own router lift-out mechanism

Adjusting the bit height on a router table can be a pain in the butt. Traditionally you needed to get into the cavity under the table top in order to make these adjustments, and it’s hard to make the adjustment and measure the height at the same time. Modern routers now offer the option to adjust height through a hole in the plate that sits in the router table, but this is usually only found on the more expensive models. Rather than buy a new tool [Urant] built his own router lift.

He’s using recycled closet rails to give his rig some smooth operation. These are the rails and runners that let closet doors hang from the top jamb. He saved them when replacing the closet doors in one of his rooms. There’s a triangular gantry which hosts the router, allowing it to move vertically on the three sets of rails. The threaded rod in the foreground of the picture above lets the woodworker adjust bit height by turning the nut at the top. Once mounted in the router table the nut is accessible through a small hole in the table surface.

Daft Punk table with iPod dock

This beautifully crafted Daft Punk table with iPod dock was built by [Dustin Evans]. The table itself was built with the help of a friend in one day with electronics added a bit later. It features an 8×8 grid of boxes with red LEDs mounted inside. The picture above is not quite the finished product, a diffuser will be added later to augment the scattering of light already provided by cutting the tip off of each LED. On the underside you’ll find a power supply and a set of speakers. The system is controlled by an Arduino which resides in the same drawer as the dock. See the final product in the clip after the break.

Needs more LEDs, EMSL biggified Conway’s Game of Life

Evil Mad Scientist Laboratories has proven bigger is better with their colossal LED table running Conway’s Game of Life. At the heart of the system is 44 ATmega164Ps controlling 352 LEDs on a 32×44 inch table; and to make it interactive IR LEDs detect the presence of objects.

The display is set up as an exhibit at the San Jose Museum of Art in tribute to [Leo Villareal]. To see a demo, catch a video after the divide.
