We made a slight update to the code and design to give the sippers 2 TTL output connections that can sync sipper interactions with external equipment such as a fiber photometry or ephys recording system.  There is now an optional step in the instructions for which pins to solder these BNC connectors (to A1 and A3), and an update to the code to enable these pins as outputs.
