Spark Fun Electronics strung together 15 button pads, a bunch of ATmega8s, programmed in some rules to Tetris, and out came a wall-sized interactive Tetris game (don’t worry, I don’t know what any of that meant either). The device, composed of 240 buttons, is designed to be intuitive,
so if you want to move the Tetris block right/left, you simply touch a button left or right of the current piece. To rotate a block you touch a button in one of the top two rows. And to drop a block you touch the bottom row.
If you want some ‘wow numbers (though again, I don’t know what they mean), there are:
- 16 microcontrollers
- Total of 256 MIPS
- 720 LEDs
- 1.5A current draw
- 1300 lines of code
- 28800 bits being updated per second
- 9 people
- ? man hours
The project is basically open source, so they provide schematics and firmware for the controller and the button pad so that you can make your own (though the man hours are probably prohibitive to most). If you’ve got the talent though, I can’t think of a more impressive way to show it off than to build a giant interactive Tetris wall board with it. It’s soldering time!
