Interactive table is slightly different than most.

April 29, 2012 By Leave a Comment

[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

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

March 26, 2012 By Leave a Comment

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.
