"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…"

Bill Porter commented on Chris Anderson's blog post Telemetry kit back in stock"@Cliff
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…"
Bill Porter commented on Chris Anderson's blog post Telemetry kit back in stock"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…"
Bill Porter commented on Chris Anderson's blog post Telemetry kit back in stock"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…"
Bill Porter commented on Chris Anderson's blog post Telemetry kit back in stock"That 'XtreamBee Board' isn't compatible with 5V micro-controllers, is it?"
Bill Porter left a comment for Todd Elliott"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…"
Bill Porter commented on Todd Elliott's blog post Announcing OpenFHSS project (902-928MHz Frequency Hopping Modem)"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…"
Bill Porter commented on Todd Elliott's blog post Announcing OpenFHSS project (902-928MHz Frequency Hopping Modem)"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."
Bill Porter commented on Todd Elliott's blog post Announcing OpenFHSS project (902-928MHz Frequency Hopping Modem)"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…"
Bill Porter commented on Todd Elliott's blog post Announcing OpenFHSS project (902-928MHz Frequency Hopping Modem)"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."
Bill Porter commented on Abe's blog post Visual Odometry For GPS-Denied Flight with a Kinect"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…"

Bill Porter commented on Eraser's blog post Freewave Radio Moving live H.264 Video, with 10 PWM Channels and GCS"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."
Bill Porter commented on bGatti's blog post Current (and Airspeed) for $1.45"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."
Bill Porter commented on John Erickson's blog post Improving Compass support for ArduPilotMega (MicroMag3, auto declination, better drift correction)"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,…"

A little about me.
24 and living in Panama City Beach, Florida I am a Electrical Engineer for the US Navy. I love robotics and electronics. I am new to UAVs but excited to build one.
Here is a video if my best robot yet, built as a Senior Design project.
and below are photos of my latest drone, SAGAR. More info on my website, www.billporter.info

Complete (hacked) setup for being able to load a Waypoint in the air.

I'm posting this for those that didn't catch it in the comments of Varun's last post.
Between Varun's modified Ardupilot code, and my modified LabView Ground Station code, there is now a complete setup available to those that have been looking for in-the-air waypoint updates.… Continue

Getting Data BACK from Google Earth and Into LabView GroundStations.
Posted on June 23, 2010 at 5:32pm 9 Comments 0 Likes
We all know it's easy to display information on Google Earth, like the position of a UAV. However getting information back, like the GPS coordinates of a mouse click, is another story. I really wanted to give my LabView GroundStation for my UGV SAGAR the ability the to 'click and go' anywhere on the Google Earth map. This is similar to the various wishes I have heard around here for the ability to upload new waypoints to ArduPilot while she's flying.
Well, I figured out how to do it,… Continue

The Trouble with Communications

Hey guys,
I'm still working on the next installment on my SAGAR drone, however my progress has slowed, as I suddenly find myself in Boston for 7 weeks. Life can be very exciting when you work for the Department of Defense.
In the mean time, I have been asked by a few people over at SocietyofRobots.com on how SAGAR's micro-controller (an Axon) communicates with LabView. Instead of a bland answer, I spent s little time writting about the different problems hobbyist can run… Continue

My own DIY drone, complete with LabView 'Ground Station' Part 1b
Posted on April 19, 2010 at 8:30am 3 Comments 0 Likes
Hey guys,
I have been wanting to fully document my SAGAR (Semi Autonomous GPS Assisted Rover) for some time now, and the 'ardupilot goes into the water' series has been so entertaining, it gave me the motivation to finally start. The first post was simply a demonstration of the LabView ground station, which has been redesigned one last time before my girlfriend is turning in the project. First I'll show the new interface, and talk about how it communicates with SAGAR, and give some…
