<div dir="ltr"><div>Hello team!</div><div><br></div><div>For those who weren't able to make it to the meeting yesterday, I'm hoping to help guide you into what is going on, so that you can start working as soon as possible! Join us on <span></span><a href="http:///" target="_blank">Slack<span></span></a>! Meeting minutes are posted there.</div><div><br></div><div>We have 11 weeks until race day (as of Saturday), and due to the <i>colossal</i> amount of risk in this project, want to have construction of <i>hardware and software</i> by the <b>five week mark</b>. That's <b>August 13th</b>. </div><div>I expect three weeks of hardware/software integration, leaving 3 weeks of slack for optimization, race tactics, and for when our deadlines slip.</div><div><br></div><div>The philosophy I pushed at the meeting were: <i>simplicity first</i> and <i>low risk</i>. </div><div>There are a billion cool things we can do with this platform - but it has to <b>work,</b> before we go down the rabbit hole optimizing it. To minimize risk, look at what is conventional - if 95% of model sailboats are a certain way, there is probably a good reason.</div><div><br></div><div><br></div><div><br></div><div>Work is progressing on getting hull plans ready for laser cutting - perhaps as early as next week, thanks to lots of effort by Norm and Mark L.</div><div><br></div><div>I am working on getting a version of Ardupilot set up with some empty functions for the various software components that are to be constructed.</div><div><br></div><div>Lots of thought is going into the various sensors we must have, and would like to have; the materials we can make the sails out of, etc.</div><div><br></div><div>Below is the exhaustive(-ish) list of action items, distilled from the meeting minutes, as I see them. Some points may change based on the outcome of others!</div><div><br></div><div>Thanks everyone - this is gonna be fun!</div><div>-Will</div><div><br></div><div><br></div><div>
