Re: Tablet computer for Navigation
"I realize this, but did not want to advise designing a system with a whole lot more than 500mA coming out of a 12v USB adapter."
Supplying more than the minimum can't hurt, except for the adapter itself consuming a bit more power and that's a "maybe". No telling how smart any adapter is, or if it is dc-to-dc or an analog regulator in there. And if someone DOES plug in an iPhone or a Droid, the extra power means it will just charge faster.
"While Raymarine may only "speak" SeaTalk (of various generations), many of their autopilots have input terminals to "listen" to non-proprietary NMEA."
Yes, but since he asked for something to speak SeaTalk to his autopilot, I'm rashly assuming his autopilot only speaks SeaTalk.
Ray-whatever they are calling themselves this week, is making a big fuss over their new displays that supposedly will integrate all sorts of toys directly with WiFi and BT, giving you a "wireless boat" and local hotspot. Which sounds all wonderful in theory, but I'm thinking, imagine a dozen boats all trying to be in the same place (as usual) during a race, and they've all got wireless systems, and now...maybe they're going to start getting confused about what's on which boat.
Oh yes, I see great potential in there. Helmsman, navigator, tactician, onboard hacker perhaps?
Or, maybe Ray will release an iApp, at an appropriate price that doesn't undercut their own market.
