Due to school preventing me from spending days at TechShop to use their printers and CAD workstations (my school lacks a technical education program sadly and my computer is on OSX so I can't use Inventor on it until I figure out how to install windows on an external hard drive) I have not made much progress on the system as of late.
I have switched from an Ardino UNO to a much smaller Nano in addition to further shrinking the interface board to a standard protoboard size. This incorporates and miniaturizes the system as it does not require another power supply. Last time I was at TechShop I focused on alternate fin designs and printed a testfit prototype. The fin is designed after standard double wedge hypersonic fins used on supersonic missiles but tapered more towards the back. The print was clean except for a bit of roughness on the trailing edge that would be smoothed out in finishing.
