I saw sparkfun make a similar table a few years back where they had multiple LED matrix screens connected together and put them into a table to play a four player game.
I decided to come up with my own version and wanted to keep the cost down as low as possible. The result is ‘The Super Pong Table’ This game is played with upto four players at a time, each player has an analog paddle controller to control their bat. The idea is to hit each ball back into the playing field. The original version included a score tally system whereby the first person to hit 20 balls was the winner. I have also come up with a better version whereby if you miss 20 balls, you are knocked out of the game – the last person remaining is the winner.
The first video shows the original version.
The second video shows the new and improved knockout version.
