Coffee Roaster Update

Rewired coffee roaster
Connectors from roaster to external electronics enclosure

The coffee roaster has been rewired with all the previous electronics moved out. The electronics will be mounted in a separate enclosure in this revised design. The new controls are based on a board set called the Atomic Pi, which includes an x86 based processor running Linux, and mounting provisions for an Arduino Nano. The Nano will handle the low-level hardware interface and the Atomic Pi will run Node Red to provide the user interface and remote networking capability.

Pinout for the connectors. The small green numbers are molded into the connectors next to the pins. Not sure why the numbering starts with 7 on the connector.
