Accelerometers are used for tilt sensing. Gravity, after all, is a force, and forces cause acceleration. So acceleromters can sense how much an object is tilted by sensing the amount of gravity applied to the sensor. For example, some cell phone games use the accelerometer built into the cell phone to control the ball in tilt mazes. (Kind of like the one here: http://www.flasharcade.com/arcade-games/g-ball-game.html ... except you control the ball by tilting the phone.) If you can get your hands on one, it'll be a sturdier (and possibly cheaper) option than creating a pulley mechanism. At the Consumer Electronics Show a few years ago, I met two separate accelerometer vendors selling 2-axis accelerometer for about $1.00 to $1.50 each, with a minimum quantity of 10,000. In retail, I imagine they cost around $5 plus tax and shipping for one 2-axis accelerometer. If you find an accelerometer using the same voltage as the Atari, all you'll need is probably something similar to a bosu ball like this: http://www.beginnertriathlete.com/cms/article-detail.asp?articleid=1272 (you can make one since bosu balls are expensive), attach the accelerometer flat somewhere on the bosu ball, and solder some wires on the accelerometer and run it to the Atari. Just an idea. YMMV. _______________________________________________ vox-tech mailing list [email protected] http://lists.lugod.org/mailman/listinfo/vox-tech
