3D printed parts of ground station/rover, Main PCB, etc.
In software development exist rule - if source code working from the beginning - that mean only one -- something wrong with a source code. Such excitement discovery was made last week by Alex -- he was wondering why main computer board starts to function right away, but 3.3 voltage regulator during last month was overheated like boiling water -- well it was simple 6 SMD components was soldered upside-down. Current was 180 milliamps, instead of 18. Fix was quick -- it takes 10 minutes to rework PCB, but positive part is components was chosen properly - all 6 SMDs was working perfectly after 1 month stress. Integration continue on GPS and Camera. HD Camera waiting it turn together with Orbitcomm backup communication modem. Integration at the rest of the week was not a full scale SNAFU, which was bothered Alex little bit. And finally -- all 3D printed parts for a rover and ground station showed up last Friday. Some imperfections was fixed - like this on a HD camera sealed box, or on camera box -- probably the thickness of a wall (target == made from carbon fiber) will be OK, but for rover testing (that part additionally to a camera box functionality will be used as a leg for a movement) plastic is not strong enough. For reduced size ground station tubes was made from aluminum, and assembly was in a progress
