Coffee roasting, especially when creating home made roasters, seems to be a geeky combination of tech wizardry, workshop skills, and an odd connoisseur mentality.
When I was looking for an alternative roasting method, having gotten somewhat unhappy with the limitations of my IR2, I looked all over for ideas.
This is my bread machine, out on the patio, on top of the beer fridge. There is an unseen $34 heat gun along side of it . The brown speckles are chaff, the papery substance that flies off the coffee beans during roasting. A piece of chaff occasionally catches fire as you do this. It looks a little like a mosquito as it comes in contact with a bug zapper. I have more information on roasting using a breadmachine/heat gun on my new Coffee Crone website.
