 * Discussion on Google+
 * OpenROV.com blog post

Summary

 * [0:40] Options for Tethering without AC power
 * [3:00] Voltage drop problem with electronics and controls
 * [~16:00] Different ways to adjust thruster controls - Arduino vs JS, adjustable vs better defaults
 * [~26:00] Ranges for limiting throttle
 * [32:40] Discussion of servo pointing down
 * [34:00] Data stream coming from Arduino - self identifying sensor readings
 * [42:15] Raspberry Pi port
 * [44:40] Camera, video, Logon to OpenROV with more than one computer?

Callouts

 * [FOLLOWUP] check voltage graphs from [4:40] against current
 * [FOLLOWUP] Some electronics diagrams were emailed instead of posted publicly - what's the best way to post/share docs?
 * [PROPOSAL] - keep current constant and adjust speed - speed isn't a limiting factor, brass props are *fast*
 * [FOLLOWUP] right now battery voltage is being measured on the wrong side of the diode, could change for next cape
 * [PROPOSAL] move mechanical/physical things to Arduino, so the people that play with motors
 * [FOLLOWUP] Fix cad files and documentation so the downward servo hole is the right size
 * [IDEA] put a serial display into the cockpit so Arduino-only people could still read values
 * [PROPOSAL] Create an "observer" connection mode so other people can view the stream without issuing controls
 * [TODO] Wireshark observations of bandwidth usage
 * [PROPOSAL] Move to 100Mb connection to avoid constant struggle with 10Mb limitation; it can be optimized, but there are tons more better things to spend time on
