"roasted using a popcorn machine as a roaster "

Seriously? I have a cheapie air popper thing that works great for popcorn.

For coffee beans, how does it work? For example, how do you know when they're roasted?

A couple references:

I'm thinking of trying this out; it sounds really easy.

From the first link: "For legal reasons I can't talk about air popper roasting too much."

And the author doesn't elaborate. Weird?

The second link mentions the possibility of injury or severe property damage do to fire, rising from the (mis)use of a popper for "off-label" purposes.

Maybe this guy is afraid of being sued by someone who'll blame him for providing information on a potentially lethal activity.
