Recap of Tahoe trip

 * Day 1: 5 OpenROVs, 60-70ft deep water, encountered scuba divers
 * recorded video, 2 entries - one with on board camera, one with GoPro
 * Day 2: Brian, Zack, John, Eric put 2 OpenROVs in the water at once and interacted
 * tried deeper dive with more balance, farther from shore, new depth sensor. Blackout, water leak at 100m
 * some leakage into main chamber at higher pressure, caused positive pressure inside tube leading to more leaks
 * battery problems - out of proportion between both sides

Designs for new end cap to test failure

 * harder to identify breakage vs glue because the part is white. New clear parts should be clearer
 * need more photos of builds, failures,

Dominik's Report on building

 * Electronics in 2.5 are a lot easier to assemble
 * Still need to glue and pot end caps, battery tubes
 * Can't get the same epoxy in Australia
 * Eric recommends slow curing, low viscosity adhesive
 * Discussion about troubleshooting an issue
 * wire for depth and IMU can be very thin. Thicker wire useful for doing more then I2C

Michael Humphrey

 * Assemble OpenROVs for middle school/high school project
 * Using OpenROV as part of a distance education program (Seward?)
 * Could use extra boards since building multiple
 * Recommends Firebase to sync between multiple databases for client streaming https://www.firebase.com/

Maker Faire Sydney - DF is preventing

 * Nov 24 Sydney Mini Maker Faire http://makerfairesydney.com/
 * Great experience to show off the ROV, let people see and touch it
 * OpenROV HQ will support anyone presenting

Going to Hawaii to test in ocean

 * Bringing 2 ROVs b/c have to back light, ship batteries
