Revised case design

5. June 2014 Zachary Amador Weekly Lab Notebooks (0)
I heavily revised the case design from my first mockup. Now the clip is a separate part, and there's one single large clip rather than two small ones. The battery no longer has an external hole, it'll be inserted below the PCB in the main compartment of the case. Also, we wanted to have a switch that would detect when the clip was being worn, so I made some recesses for metal plates on the back surface of the case and on the clip. We hacked up a coin cell battery clip to get a piece of metal with bent out tabs that will touch the other plate when the device is not being worn. Also, there are cutouts for the wires that will connect these metal contacts to GPIO pins on the PCB.
