Gaahhh...Software Serial (AFSoftSerial)
This is sort of the second half to an earlier discussion I started about problems with software serial that I was having with the Arduino. I didn't like the fact that the SoftwareSerial library would hang if serial input was abruptly cut off, so some
Read more…New UAV project, best aircraft to use ?
Hello everyone,Great site, I have been lurking for a while now, and It’s excellent to see the progress of some of your endeavors.A friend and I are beginning our first UAV project. We are just getting started with the hardware, and expect a 2 lb (hig
Read more…Balloon Dropped Gliders
Hello All,I have been working on a balloon dropped glider off and on for a couple of years as time permits. The goal was to carry my glider aloft to about 60K feet and release. The glider was then supposed to navigate it's way back to the launch site
Read more…accelerometer, gyro or infrared?
Hey everyone, I'm new to this site. I'm starting on a uav project and I had a question that googling hasn't sufficiently answered.I've noticed that, for tilt sensing, many designs that I've seen are using an infrared setup to detect the difference in
Read more…Programming Problem
I've come across a small problem with some software serial code in Wiring for the Arduino Diecimila. This is the function I'm using to read information from a GPS module:int SWread(byte rxPin){ byte val = 0; // unsigned long beginTime = millis();
Newbie challenge: high altitude drop
Dear DIYDrones members,I am a total newbie so forgive me if my question is rather basic. Also, apologies for my bad English, as I am not a native speaker.I wanted to know whether the following would be feasible and at what cost, roughly speaking.1. I
Read more…Navigation calculations??
Hi everyone!I need to write the code for navigation calculations(distance and bearing) for my UAV project. I went through some of the methods like pythagorus & haversine but I am really confused. Can somebody share the code/method which has been succ
Read more…First Autopilot(VERY WIP)
I'm working on my first autopilot. For the moment, it's just the GPS part of the autopilot. I have a GPS that is outputting NMEA data and I'm trying to develop a parser for that data. I'm using the parallax propeller and It's 1:42 in the morning so t

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…Wiring or Arduino UAV controler PCB based on inertial sensors, please suggestions!!!
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…Barometric Altimeter
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…Manual Control Problems
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…n00b questions
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…low cost radio systems
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

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

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…Radio control range
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…SCP1000 pressure and temp sensor
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

Hi Everybody!Iam working out a design for servo controller which receives signal from R/C receiver in manual mode & a microcontroller generates signal in auto mode. One channel of receiver to be used for switching between modes.Following idea came in
