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. Batters have plenty of time to set a swing -- unless, of course, they are distracted by the fascinating light display.
mrdon, nothing to do with this. I just wondered if you knew if line conditioners work or not. I have an audio hiss from my tv that I want to eliminate and before I buy a conditioner...I just wonder if they work if you know?
Elizabeth M Ok and thanks for the confirmation. I have two dogs and I do realize the fact that they can feel pain just like humans. Its good to know the designers wanted to build a deterrent device without the feature of inflicting pain on animals. Its a cool gadget!!!
As I was going through the Gadget Freak slides, the "Colorado Smart Bike Shifts Itself" caught my attention because of the The Lexus F Sport Roadbike article Charles wrote. In his article, the Lexus bicycle uses an electronic derailleur to shift gears. The smart bike built by the Colorado State University engineering students uses standard off the shelf electronic parts for their controller. I'm just wondering what is the cost differential between the Lexus F Sport roadbike derailleur device compared to Colorado State -U engineering students design? Curious as to the controller circuit the F Sport bike uses as well.
Elizabeth M, I like this gadget as well because its physically safe because of the foam rockets. This gadget also remind of the science demonstration I performed on of my kids elementary school visit. I took a toy robot that launched foam missiles and wired it to a Handy Cricket microcontroller board. A light sensor (photocell) was attached to the Handy Cricket so that a wave of my hand would launch 3 foam rockets into the classroom audience. The kids loved it and I had a blast building it and demonstrating the modified robot launcher to the classroom as well.
Yes, Cadman-LT, a zapper would come in handy especially with a raccoon, since they are generally such bold animals! I think cats might run off with just a firm wave of the hand and a bit of yelling at them. Raccoons, not so much. :)
