Please tell us a bit about your UAV interest

I used to work as an engineer for Advanced Ceramics Research, with the Coyote, Silver Fox, and Manta UAVs. Right now I'm interested in pushing the envelope of "DIY Drones" and seeing what kind of performance I can get out of off-the-shelf parts :)

"Hi there,

Wow, it's been awhile since I've worked on this - and due to some issues with the firmware way back then I grounded that aircraft o.O

As for the code - I'm trying to remember.  I used RPi Cam Web interface for the HD streaming and I…"

Ryan Nelson replied to Ryan Nelson's discussion TCP/IP connection in Mission Planner
"The telemetry radio is just a wireless serial port, so if you connect your serial ports to your APM 2 as seen in this picture, you should be just fine!



I'm not sure how you set up your MCU, but in mission planner I just connect to the IP address…"

I didn't get any shots of the laptop unfortunately, and I didn't get to watch the video on the screen myself, though Jasmine and Scott reported…"

Ryan Nelson commented on Scott James's blog post FPV Multirotor Racing :)
"This is awesome!  Just came across this while looking into racing.

I'm planning on racing the micro FPV quads with a friend of mine.  We decided to go micro so we could race all together, instead of one at a time.  Whenever the slow boat from China…"

"No prob!  And I solved my issue this evening:

By mistake I had "XONXOFF" instead of "-XONXOFF" in my ser2net configuration file.  No idea what it was doing with that, but I was supposed to have it disabled.  One character caused so many headaches!…"

"Solved:  I had "XONXOFF" in my ser2net config instead of "-XONXOFF"Figured that out by looking here: http://pixhawk.org/dev/remote_serial  NOTE:  Do not use the "-u" as it will not connect with it."

Ryan Nelson replied to Ryan Nelson's discussion Telemetry issue
"Does anyone have any idea what might be causing this?  I've read things about the GPS being starved for power and not putting out good data, but I'm using the 3DR power module as well as a 10 amp BEC on the servo rail for power.  Maybe the pixhawk…"

Ryan Nelson replied to Ryan Nelson's discussion TCP/IP connection in Mission Planner
"So I'm currently using a Raspberry Pi computer to handle both video and telemetry.  The Raspberry Pi has a serial port built in on the GPIO connector (a quick search can grant you the pinouts).  You also have to disable the system's use of it before…"

"Hey! Apologies for not getting back sooner. When I get to a real computer I'll give you the rundown of the hardware and how I made it work. I was on vacation for the last few days so I'm just getting back to the real world :)"

I'm having difficulty with my telemetry stream.  I am able to connect via TCP to my telemetry stream coming from my Raspberry Pi.  APM Planner is only able to update some of the Pixhawk parameters (gimbal stuff can't be written, other stuff can, not…

"Nice!  Feel free to ask if you have any questions.  Right now I'm having issues with getting servo passthrough to work with the autopilot, but I plan to hit it hard this evening.  Also my telemetry didn't work with Mission Planner on windows, but…"

I've had my pixhawk connected to APM Planner 2 in Ubuntu via TCP/IP with no issues.  However I just got a different laptop, and I'm trying to connect to Mission Planner over TCP/IP.When I try, it begins to list parameters ("got param xxxxxxx") and…

Ryan Nelson replied to Ryan Nelson's discussion APM Planner 2 custom widget
"Thank you!  That's the sort of thing I was looking for!
It looks like I have a little bit of learning to do to set this up, but it is awesome that I can get the functionality that I need.
I'll have to play with it once I get some time to sit down…"

Ryan Nelson replied to Ryan Nelson's discussion Bingo (backup) battery ideas
"I plan to add the backup battery to the circuit in parallel so there should be no brownout issue.  Trouble with that is if I have a shorted cell in my main pack I can not recover from that, as it will probably kill my backup battery too :/"
