This week, we’ve begun our CAD modeling of the various Mothers of Invention in our display. Soon we’ll combine them into a full CAD model of our design. We’ve been working on an improved track/sensor design that we hope will improve the machine’s ability to detect a ball rolling down its track, as well as some mounting designs to display the sequence in our machine’s frame. We’ve also started ordering materials and tools so we can get back to the lab and start building this awesome machine next week.
