"Nothing else matters except marketing. None of the other shit is important; it doesn't even matter if everything is working right, you can fix it later. Seriously, marketing is the most important thing. If you don't do it right, you've got nothing."
I smiled, nodded, and said something like "Hmm.... OK." and that was that. The significance and truth of his advice didn't really sink in until later, after the interview was over and I went back to working at my desk. I'm kind of like a "fish out of water" when it comes to marketing.
(Unfortunate minnow found dead on the deck of AMOS a couple of days ago.)
AMOS spent another 4 days on its own at Woolastook this past week, and collected some good temperature and pH data (https://www.innaturerobotics.com/sample-data-1). Although it has been a while since I did a very crude calibration of the probe with some kitchen vinegar and tap water, it does seem as though the water around Woolastook is a bit acidic. Apparently that's not uncommon in this particular part of North America. On Thursday, AMOS set a new single day distance record of 12.25 km.
The weather is currently quite cloudy and rainy, so I have AMOS back home where I'll see if I can fix some intermittent low voltage issues on the +5 V supply, and maybe hook the GPS antenna back up. There seemed to be a few spots around Woolastook where finding a GPS signal was a bit of a challenge.
