Homebuilt Arduino Controlled Coffee Roaster



Well, 2 years later and MANY requests, this is a more detailed technical follow up of my coffee roaster build.
It covers: Overall design, Roaster Plenum, Chaff Collection, Dump Mechanism, Arduino Control, Zero Cross Detection.

The plastic roasting element that is used in the build can be found here https://www.aliexpress.com/wholesale?catId=0&initiative_id=SB_20200113210052&SearchText=3400w+welding+element

I know the quality is not crazy good, but a fast video edit is the only way for me to reasonably update anything on this channel
