Sparkfun is known for modding retro gadgets with new school tech -- their rotary phone that accepts cell phone SIM cards was just one of those ideas. Now the company has made a coffee table that lets you challenge the people lounging around you to a game of Pong.

The tabletop is built with 4,096 LEDs which play out a game of Pong controlled by four attached Atari controllers. After the jump more shots and an explanation on how the company made this one-of-a-kind piece...

"The table itself was bought secondhand and refinished. Then it was retrofitted with proper mounting for the big LED matrix. The individual LED matrices were mounted on a custom plastic frame. All this work was done by resident mechanical engineer and lady-killer Casey Haskell. The matrices are connected 8 to a row, all 8 rows controlled via a custom router board connected to an Olimex LPC2106 development board. The entire rig is powered by a hacked 500 watt CPU power supply."

Here's a look at the underside of the table with all the circuitry.

The entire table consists of the following:

  • 65 total microcontrollers
  • 4096 RGB 256 color LED's on 64 Matrices
  • 7-9 Amps power draw
  • 130,944 bits updated per second
  • 1 LPC2106 Master Controller
  • 1 Custom router board
  • 8 Custom power boards

And here's a look at one of the LED modules used in the table.

What you see on the floor beneath the table here is actually a mirror in order to inspect wiring without having to crank your neck.
