"ArduSub is a loooong way off. No GPS underwater, and no inexpensive odometer solutions. Mems gyros are getting close, but still not as good as laser ring gyros.
Though if there are breakthroughs in sensor tech, I'd love to help the dev teams. I…"

"Grr, these would be perfect for the education outreach STEM program I am part of. Shame they are sold out everywhere."

Like I said, the multiple issues we've seen on SOR forums was corrected by adding level shifting up. It has nothing to do with power limits.
I've brought it up on Sparkfun comments section and I have been ignored. I'm guessing it's…"

"Thomas:
The people having problems over on SOR were not using the high power Xbees, and they solved their problem by adding their own level shifting to the DOUT line of the Xbee carrier board.
It's kinda of aggravating that these boards claim to…"

"Does the board properly shift the logic levels, ie does it amplify the DOUT line of the Xbee to 5 V logic?
Many of us have had issues with Xbee regulated boards (especially the one from Sparkfun) that claim to convert between 3.3V logic and 5V…"

"That 'XtreamBee Board' isn't compatible with 5V micro-controllers, is it?"
"Todd,
I think you mentioned in a comment that you were looking for a job. Economy sucks, but the government is still hiring; assuming the big boss stops freezing budgets. Make sure you use USAjobs.gov as it's the portal all branches of the Dept of…"

"I'd say everyone in the hobby world is jumping to zigbee just because of price, but in the professional world, we laugh at them. Last event that I attended that had mixtures of zigbee and freewave radios, the zigbees were getting crushed in…"
"Todd,
Just in case there was any misunderstood tone, I am fine with the jump coming from personal profit/dev cost, it just wasn't clear in your previous comment which is why I was asking."

"Todd,
'Your cost' to the selling cost (330 to 794), what causes the jump? Did you mean "That did NOT include x-ray inspection, and final assembly"?
I'm curious to see where your design goes and if it gets picked up for regular production. I work…"

"Maybe i'm blind but I can't find a BOM. What is the cost to build these?
At those specs especially 500mW, this seems like a real competitor to some of the commercial products."

"Yeah for realistic quad sensor development!!
Seriously, the videos from the two groups using external movie studio quality motion tracking are passed around the office now to get a good chuckle from my co-workers. It must be fun for them to live in…"

"The team I mentored is going to the Orlando competition. I wish them luck!!"
"Lol, I was about to say, did anyone mention the price of FreeWaves?
Cheap (and very well proven) for government use (we have a ton of them at work) but expensive to the at-home DIYer."

"Current transformers measure AC.
But you can use a hall effect sensor to measure DC current. They are about the same size and weight, but cost a little more."

"I.S. has the right idea. Many of the commercial drone systems I use at work store the declination information in the control console. Also makes updateing the data easier.
Though it does require 2-way comms on the control console and, well, having…"
