Bean sorter lights

Our bean sort project has heated back up–literally and figuratively. Gene finished the prototype light stands and shipped them out. Here is a picture of them working. They heat up a ton when they are under constant current, so I have ordered a manual PWM light driver (with a dial for brightness) and an PWM driver that I should be able to control with one of the DAC’s on the Raspberry Pi. All of that should arrive within the next few days which means I am the one who is holding everyone up because there are so many things that I have to do before I can test them. I can hardly wait to get them in my hands.

In the mean time, I am working on the pixel to world coordinate calibration model for the beans. I hope to have that done sometime today–by Thursday at latest. Then I can work on controlling the lights and capturing images with the Raspberry Pi.
