For a workbench, desk, or even a dining room table, there’s nothing quite like a massive piece of laminated maple put to use as the surface of a table. Whether in the form of butcher block, a shop class table, or in [Dillon]’s case, a reclaimed bowling lane, laminated maple provides one of the best possible table surfaces.
A while back, [Dillon] found someone on Craigslist willing to part with an eight foot section of a bowling alley for about $300. After trucking this two and a half inch thick, 250 pound monstrosity home, work began on converting it to a dining room table.
Bowling alleys are constructed by workers laying down maple strips and nailing them together one row at a time. This provides a stable surface when mounted on a concrete platform, but is completely insufficient for a table. To keep his bowling alley table from sagging, [Dillon] routed out three slots for aluminum bars going across the width of the lane. These bars were then screwed into each individual maple strip in the lane, resulting in a very sturdy surface.
The strengthened lane was then resurfaced with the help of a huge industrial belt sander and finished with a satin polyurethane. The legs of the table are made out of CNC’d 18mm Baltic birch plywood held together with metal fasteners.
The end result is a beautiful table ready to last 100 years. Considering [Dillon] spent less than $1000 on this table – and the price of eight feet of 2.5″ butcher block – we’re going to call this a win for [Dillon], his kids, and grandkids.
We’ve seen strollers and car seats that have a steering wheel for the baby to play with (like in the opening of The Simpsons). But what we hadn’t seen is a stroller that allows baby to actually steer. You might think that a putting a motorized vehicle in the hands of someone so young is an accident waiting to happen. But [Xandon Frogget] thought of that and used familiar hardware to add some safety features.
The stroller seen above is a tricycle setup, making it quite easy to add motors to the two rear wheels. These are controlled by a tablet which you can see nestled on the canopy of the stroller (look for the light reflected on the glass). This interfaces with two Kinect sensors, one pointing forward and the other pointing back. They continually scan the environment, looking for obstacles in the stroller’s path. You can see [Xandon’s] little girl holding a Wii Wheel, which connects with the tablet to facilitate steering. A test run at the playground is embedded after the break.

Ah, the cocktail arcade cabinet. With the right design, its able to blend right in to any living room decor, much more than any traditional stand-up cabinet, at least. [graham] over on Instructables didn’t tear apart a 30-year-old arcade cabinet for his new coffee table. Instead, he built one from scratch, connected it to a Rasberry Pi, and brought hundreds of arcade classics right in front of his couch.
The build began by cutting up some wood to house the 24″ LCD screen, Raspi, and arcade controls. The LCD screen is supported with a rather clever system of cross braces screwed into the VESA mount, and of course a piece of perspex protects the screen from the inevitable spills and scratches.
The joystick two blue ‘player’ buttons and the player 1 and player two buttons are wired directly to the GPIO pins of the Raspberry Pi. The Raspi boots up into a selection of MAME games, but there’s also an option for opening up the window manager and browsing the web.
It’s a very neat build that’s a lot smaller (and easier to build) than a traditional cocktail cabinet. As [graham] is using it for a coffee table, it might get more use than a regular MAME build, to boot.
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.

[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]

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.
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.
