DIY machine sorts M&Ms and Skittles by color

William Pennings built this wonderful machine that automates the arduous but necessary task of sorting M&Ms and Skittles by color. (Insert Van Halen joke here.)

"It's pretty quick and sorts about 2 pieces of candy per second" Pennings says. "It uses Arduino microcontrollers and stepper motors for quick and precise movement. A TCS34725 color sensor performs the measurements. Furthermore, the device is equipped with LEDs in several spots which nicely complement the overall look of the machine."

  1. Oh it KNOWS. It KNOWS one is delicious chocolate and one is crappy tasting jelly goo. It KNOWS it in its soul.

  2. I used to work with someone who claimed he went through a large bag of M&Ms crushing one against the other. The toughest one, the one that crushed the others, he set aside and mailed to Hershey with instructions to use it "for breeding purposes".

    I guess it won't be long before there'll be a machine to do that too.

  3. No, it doesn't get rid of the Skittles.

  4. It puts the brown ones in their own dish, with a wall around the rim. /s
