The team is making progress..
Inbetween procrastinating and discussing how to build a 22ft Stargate Christmas Tree, the team has actually been making some progress.
Mal has been prototyping some Pi HAT modifications from the last year design to accept a (physically) larger I2C expander, time of flight sensors and dedicated servo connectors.
