Followup Items From 2013-02-14_Development_Call

 * Voltage drop issue causing computer reset
 * Best way to share/post docs?
 * Motor speed throttling - Arduino or JS
 * Battery voltage being measured on wrong side of diode, possible change for next version of cape
 * Fix cad files and documentation so the downward servo hole is the right size
 * Wireshark observations of bandwidth usage
 * Work on increasing bandwidth to 100Mb

Proposed Agenda Items

 * Changes to Under Development page, progress reporting (Peter)
 * H264 camera options (Peter)
 * Planning for Maker Faire?
