Mind-Controlled Beer Pong Gets Easier as You Drink

Wouldn’t it be nice if beer pong could somehow get easier the more you drink? You know, so you can drink more? [Ty Palowski] has made it so with automated, mind-controlled beer pong.

[Ty] started by making a beer pong table that moves the cups back and forth at both ends. An Arduino Nano controls a stepper that controls a slider, and the cups move with the slider through the magic of magnets. The mind control part came cheaper than you might think. Back in 2009, Mattel released a game called Mind Flex that involves an EEG headset and using brain waves to guide a foam ball on a stream of air through a little obstacle course. These headsets are available for about $12 on ebay, or at least they were before this post went up.

[Ty] cracked open the headset added an HC-06 Bluetooth module to talk to the Arduino. It’s using a program called Brainwave OSC to get the raw data from the headset and break it into levels of concentration and relaxation. The Arduino program monitors the attention levels, and when a certain threshold of focus is reached, it moves the cups back and forth at a predetermined speed ranging from 1 to an impossible-looking 10. Check out the two videos after the break. The first one covers the making of the the automatic beer pong part, and the second is where [Ty] adds mind control.

We’ve seen a different headset — the hacker-friendly NeuroSky Mindwave — pop up a few times. Here’s one that’s been hacked to induce lucid dreaming.

Beer Pong Difficulty Level: 10

Beer pong is a fun enough game for those of a certain age, but one thing that it lacks is a way of cranking up the difficulty setting independent of the amount of beer one has consumed. At least, that was the idea [Ty] had when he came up with this automated beer pong table which allows the players to increase the challenge of this game by sliding the cups around the top of the table.

The build uses a belt-driven platform under a clear cover with a set of magnets attached. Each of the cups on the table has a corresponding magnet, which allows them to slide fairly easily back and forth on the table. The contraption is controlled by an Arudino Nano with a small screen and dial that allows the players to select a difficulty level from 1 to 10. The difficulty levels increase the speed that the cups oscillate on the table, which certainly adds another layer of complexity to this already challenging game.

While we hope to eventually see a beer pong table that can automatically arrange the cups as the game is played, we do appreciate the effort to make an already difficult game even more difficult. Of course, if you have problems with the difficulty level you might want to pick up a PongMate CyberCannon Mark III to help with those clutch beer pong shots.

Trick Shot Bot Flings Balls into Wine Glass Every Time

We’ve heard of beer pong, but we’re not sure we’ve heard of wine pong. And certainly never wine pong automated with a ping pong ball throwing robot like this one.

There’s not a huge amount of detail available in the video below, and no build log per se. But [Electron Dust] has a few shots in the video that explain what’s going on, as well as a brief description in a reddit thread about the device. The idea is to spin a ball up to a steady speed and release it the same way every time. The rig itself is made of wood and spun by plain brushed DC motors – [Electron Dust] explains that he chose them over PWM servos to simplify things and eliminate uncertainty in the release point. The ball is retained by a pair of arms, each controlled by a pair of hobby servos. An Arduino spins along with everything else and counts 50 revolutions before triggering the servos to retract and release the ball. A glass positioned at the landing spot captures the ball perfectly once everything is dialed in.

Here’s hoping that build details end up on his blog soon, as they did for this audio-feedback juggling machine. And while we certainly like this project, it might be cool if it could aim the ball into the glass. Or it could always reposition the target on the fly.
