Example of logic control.
This project is a game to see how high you can jump.
It is an exhibit displayed by TXU at the American Airlines Center in Dallas.
We were commissioned to re-design the electronics and logic controls.
You jump as high as possible and hit a button on the front of one of the basket balls.
It's actually two games in one. One on the left and one on the right.
Each ball is cut in half, filled in Fiberglas and mounted in a wooden frame.
The green plate on the side has two light bulbs back lighting it to illuminate showing the winner.
A button is placed in each ball.
The top two balls cause all the lights to sequence in a dancing manner signifying great fanfare.
The game logic dictates that if I hit a lower ball, I can still hit a higher one and the score can increase. The score cannot decrease however if a lower ball is hit until the game resets.
Each button is protected from being pushed in too much or from being pulled out.
The game takes a ton of abuse and must be pretty vandal resistant.
Shown here is the brains for one side of the game.
It is composed of and programmable micro controller, and digital input board, a relay current step up interface and a power supply.
The relay interface also controls recorded sounds of varying degrees of applause.
The lower ball trigger a recording of a few claps but the higher balls you can reach, the more wild the applauding increases.
It has seven discrete clapping sounds.
Shown here is the sound recording module and a small pre-amplifier.
