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!
Engineers at Fuel Cell Energy have found a way to take advantage of a side reaction, unique to their carbonate fuel cell that has nothing to do with energy production, as a potential, cost-effective solution to capturing carbon from fossil fuel power plants.
To get to a trillion sensors in the IoT that we all look forward to, there are many challenges to commercialization that still remain, including interoperability, the lack of standards, and the issue of security, to name a few.
