No Circuit and No Case... Yet April 30

Once again, Cailey and I decided to try out a new design for our final project since we are having trouble making our current case design which is an alteration of Cailey's first box design; the 1/8'' delrin melts with the wrong laser settings so the holes for the screws get ruined. We spoke with Oscar and he suggested that we should try Kelsey's lantern case which is sturdier and can be easily adjusted to fit our project. 

Kelsey's Lantern Case as an esp.

During class, we made the battery holder for 2 AA batteries (Kelsey's design was for 3 AAA batteries) and the bottom of the the case; Oscar will continue to work on the complex circuit in his office at Olin. We wanted to dedicate our time in figuring out the best way to increase battery contact which was a major problem for many of us in the lantern project. The way we were going to increase battery contact was by using Frances' and Essie's method of warping a piece of metal with a hammer into a small mound. This way the flat node of the battery would easily touch the metal piece.  The plan was to make a sandwich; bottom piece, metal sheet, and battery holder.

Before warping the metal sheet, Oscar realized that our sound sensor circuit would need 5V instead of 3V which would require at least 4 AA batteries. This meant that we would have to make further adjustments to Kelsey's lantern case (make it bigger) and that we would have to worry about contact between the four batteries and our complicated circuit. Thus we were back to square one, no case and no circuit to work with.

The good news was that Oscar allowed us to use a manufactured battery holder instead of designing one because there is only one class remaining. This eliminated issues with battery contact. We just need to create a new case design that would fit a 2.5''x 2.3'' battery holder and the invisible circuit. To keep things simple, we agreed to use my box design from the first project.
