If there’s one game that deserves to be overengineered with hundreds of LEDs, sensors, and electronic modules, it’s beer pong. [Jeff] has created the most ostentatious beer pong table we’ve ever seen. It’s just shy of playing beer pong on a single gigantic LED display, and boy, does it look good.
The table includes a 32×12 grid of LEDs in the center of the table, with 10 pods for Solo cups at each end of the table. These pods have 20 RGB LEDs each and infrared sensors that react to a cup being placed on them. The outer edge of the table has 12 LED rings for spectators, giving this beer pong table 1122 total LEDs on 608 individual channels.
With that many LEDs, how to drive all of them becomes very important. There’s a very large custom board in this table with a PIC24 microcontroller, TLC5955 PWM drivers, and enough IDC headers to seriously reconsider using IDC headers.
Put enough LEDs on something and it’s bound to be cool, but [Jeff] is taking this several steps further with some interesting features. There’s a Bluetooth module for controlling the table with a phone, a VU meter to give the table some audio-based visualizations, and air baths for cleaning the balls; drop a ball down the ‘in’ hole, and it pops out the ‘out’ hole, good as new. If you’ve ever wondered how much effort can go into building a beer pong table, there you go. Video below.

Holy cow. The amount of detail and functionality that went into this Interactive LED Beer Pong Table is absolutely incredible.
The table features 384 individually controlled RGB LEDs, covered with a 2′ x 8′ Lexan sheet to protect them from spills. Each cup holder (pod) contains an additional 4 RGB LEDs and an IR sensor that can detect whether or not the cup is in place — if it is removed, the IR sensor triggers an animation on either the 32 x 12 LED grid across the middle of the table or the other pods.
The rings of LEDs on the outside edge act as VU meters and pulse to the music in different animation patterns. What is really impressive is that [Jeff] also included a ping pong ball washer — A water reservoir connects under the table between the two LED rings at either end. When you put the ball into one, it gets sucked underneath and pops out the other side clean!
You seriously have to see the video of this thing in action.

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.

You can take the guy out of the frat house, but you can’t take the frat house out of the guy. [Evan Flint] proves this with his incessant need to have a beer pong game at all of his parties. But now that he’s growing up, and living in nicer places, he doesn’t necessarily want to have the oft-messy game in his home. So he found an electronic solution to his problem. Electropong is like an electronic dart board for playing beer pong. You won’t find beer in the cups, but you’ll still find plenty of fun.
The game includes the triangle of cups that makes up a traditional playing area. In the bottom of each cup is an RGB LED that will keep track of each player’s hits by lighting the cup in that team’s color. Illuminated buttons provide a way to control the game, with an LED marquee to read out the score.
[Evan] mentions some difficulty in recreating the physics of a cup full of beer. He says he overcame the challenge, but alas, there are no details on how. We’ve asked him to update his post so check back for more info.
Guess who built this contraption? You’re right, college students. But as much as we like to make fun, the subject of Beer Pong is our addition, not theirs. The device uses an air stream that can be directed along two axis to control and sort ping-pong balls.
Unlike the lethal ping-pong ball launcher, the goal here is elegant control of the ball. They’ve achieved a great success. Watch the video after the break to see balls sorted into beakers by color, transferred to vessels over a large distance, and navigated through an elevated obstacle course. To give us a hint of what you can do with this, we see the machine controlling an apple, an onion, and a water bottle at the end of the video.
