I'd like to see a variant of this capable of separating a mixture of M&Ms and Skittles.
So it puts all M&Ms in one pot and Skittles in the other? Or so that it can deal with all the different colours between the two? The first would be tricky!
if only this existed back in Van Halen's heyday http://en.wikipedia.org/wiki/Van_Halen#Contract_riders
Came in here to see if someone would mention it. Glad to see I was not let down ;)

I first heard the story as an urban-legend-style tale about the crazy foibles of famous people, but I love that it was driven by practical considerations.
Fluorescence-activated cell sorting uses the same idea as in the M&M sorter linked here, except with lasers instead of an iPhone camera and uses an electron gun to deposit charge onto a droplet containing exactly one cell as it falls through a magnetic field to sort it into bins. Madness!

That's a high-speed computer-vision optical pea sorter. Yes, each and every pea in that huge flow of peas is examined by a computer vision system. Tiny high-speed air jets are kicking out the rejects during the brief period the peas are in free flight.
Here's a blueberry sorting machine, throwing out anything that doesn't look like a round blue blueberry:

That machine could sort M&Ms by color, easily.
The food industry has lots of machines like that. The technology was first applied to large fruit like tomatoes. It's now so cheap it's applied to rice and grains.
That's low-speed sorting. This is high-speed sorting: https://www.youtube.com/watch?v=DogZJmThRSE That's a high-speed computer-vision optical pea sorter.

- what kind of sensor are they using that they need 2 seconds to scan?
- in comparision with 2 seconds, a phone camera with results sent over bluetooth is indeed fast. Not my branch at all, but I wonder what latencies he's looking at? Should surely be tens if not hundreds of mSec?
