Gadget Freak Case #148: Improve Your Batting Average without Steroids

Typical pitching machines make it hard for a batter to prepare a proper swing. To improve his performance at bat, Nathan Loden created this pitch alert system by attaching an IR LED and sensor to the ball feed mechanism. When the next ball up is blocking the sensor, the signal is fed into a circuit that switches on a bank of high-intensity, flashing LEDs. The batter has plenty of time to set his swing unless, of course, he is distracted by the fascinating light display. So go have a slugfest!
