Crazy Coffee Roasters

This crazy computer controlled coffee roaster by Matthew Williams is just one of many stunningly elaborate machines displayed on Sweet Marias. “Here’s my homemade PID’d West Bend Poppery I setup. The PID is a Fuji PXR4 that can be used standalone or interfaced with my laptop via a USB cable. It’s pretty much self-contained except for the external variac that I use to control the fan as the roast progresses.
