Popcorn-Popper -> Coffee Roaster Mod

the-few writes "Tom Gramilas (Toms-roaster@columbus.rr.com) created a computer-controlled coffee roaster using an old West Bend Poppery I popcorn-popper (popular among home roasters with a modding mindset), a few thermocouples, and an old DOS computer. The code he wrote to control it is available from his site on request, and uses a flexible control algorithm to control roasting segments. Pictures and roasting profiles included."
