in my basic x AP ive been using a whatchdog timer in place of a failsafe and it has worked fine . i have even had bad gps , waypoint data ect and have had no problems recovering manual control . would use of a watchdog timer on the arduino project he
Read more…Has anyone looked at the Dragon On Screen Display from Intelligent Flight? I ran across this while looking at the Hobby Lobby site for the pilot view FPV 2400.It looks like an easily integrated system for a newbie like myself.Thanks, Roger
Read more…Hi to all,I can see you community are thinking in arduino for UAV controllers, i am designing some uav boards for a complex universitary project but development is too slow and i am thinking to build a wiring or arduino based PCB with all hardware in
Read more…Hi everybody!Is there any barometric altimeter based on sensor like MPX4115A available, which can give the altitude data via serial comm. I tried searching but did not came across any.What do you guys think about designing one as an open source proje
Read more…As some of you may know, I've been building a UAV based on an Arduino Diecimila and a Multiplex EasyStar. The autopilot is pretty much done (though I'm sure it'll need to be tweaked once I do flight tests), but now I'm having a little bit of trouble
Read more…Hi Guys,Just wondering what you guys think of putting a copilot on a coax heli. I want it to stabilise the heli during waypoint navigation so all I need to worry about is direction, airspeed and altitude.I'm just wondering if there would be much bene
Read more…is a piezo gyro made with accelerometers or is it somehow different?accelerometers measure translation and not rotation, correct?which is more commonly used, a two-axis or three-axis accelerometer?also, which is a good one to use (for testing / learn
Read more…Does anybody in the group know of a utility that could convert relative coordinates in feet / meters to absolute coordinates by providing a set of long/lat coordinates and a origin / staring coordinate
Read more…Since UAV activity is largely constrained by the see-and-avoid issues;I though it would be appropriate to propose a solution which is compatible for every form of flight from gnat-weight to jumbojets. I've worked this out is a simulator - but here is
Read more…I dug out an old VEX radio system I got a couple of years ago from RadioShack.This is a 6 channel FM transmitter with a small receiver.The receiver provides a direct PWM output.But it gets even better. You can still buy the TX/RX combination fromhttp
Read more…i really need someone to help me get an autopilot working from your guys code. I feel like the only guy using windoze ;).If we can, can we use a NMEA GPS (i have a GM-11 USB) and same parallax servo controller. Programming inst' my strongest point. I
Read more…after designing/building and testing multiple electric airframes I have decided to try something pre-built and with lots of room. I am now using my trusty Hangar 9 Alpha 60 gas trainer. I have integrated the UNAV Pico-pilot, 900mHz wireless data TX,

Read more…I have two sony SuperHASS CCD that basically does 640x480 out of an NTSC. This was to be used for FPV and panoramic views with realtime live video feeds and recording (the panoramic view has a huge lens attached to it. I have been reading and i wante
Read more…I received my EM-408 GPS module in the mail the other day, and just now had a chance to check it out. However, so far it hasn't been working for me. Basically, the setup I have is the GPS module connected to my Arduino board, which is connected to my
Read more…I have decided that I am going to build my own Autopilot/IMU for my UAV. I know there are plenty of units that I can buy off the shelf but that would take the fun out of it for me. I want to build my own and really understand how everything works. I
Read more…What an awesome UAV resource, you guys have done some really fantastic stuff.I am planning to build a Heli UAV and for now doing my research. Obviously the most complex thing is the autopilot. I am planning to use Windows Mobile-based smartphone as t
Read more…The project i'm working on right now is still in the drafting stage, but i'm looking into radio control systems for it. I'm wanting the most range i can get without getting too heavy. Does anyone know any sites or systems that can help?
Read more…HI!New to the group, so thought I'd say Hi, and I also have a problem....I'm trying to get my Arduino to talk to a VTI SCP1000 sensor using SPI. I've got the SPI down OK, but the data I'm getting from the sensor for the temp reading is weird. Below 2
