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.
Oh and if you have no idea what a beer pong table is… here are the rules. The basic premise is you try to throw your ping pong ball into the opposite teams cup — if you succeed, they have to drink that cup and take it off of the table. Whoever sinks the most cups wins.
