[KLOZ] submitted his final project from college. Rather than an expensive CCD camera, he used a set of colored
resistors LEDs and a light dependent resistor (I’m assuming he means a photo resistor) to determine the color of a product (m&ms). He used the carriage from an old HP inkjet, a custom cnc cut wheel to separate and deliver the m&ms and a Parallax propeller micro controller board to tie it all together. Now he can hog all the green ones for himself.
Update: Yes, I’m an idiot. I did mean colored LEDs. People who caught me will get an email – I’ve got something for ya.
