Things are happening fast and furious with the bean sorter project. The pre-prototype lights Gene made for me arrived. They are just perfect. He had them all hooked up so all I have to do is flip a switch. In addition, two light controllers arrived in a separate package. Both of the are Pulse Width Modulated dimmers, but one is controlled manually with a dial and the other is controlled digital via a computer–in this case, a RaspberryPi. Can hardly wait for the weekend to see if I can get the control part of this thing going.
