Strange problem - one servo works but two (Y-connected) don't?

Have a very weird problem at the moment, I have my ArduPilot (328 board) aileron servo output to a Y-lead for a servo in each wing half, however just suddenly the servos appear dead but when I plug the servo's in singly they work.

The Y-lead is fine

Any use for an Ipaq?

Hey Guys.

I've just been given a box full of Compaq Ipaqs!  There are loads of H3660s and a couple of more recent ones, a 3950 and a 3850.  None of them have BT or WiFi, but the more recent two can be expanded with wifi compact flash cards fairly easy

ArduIMU+ with PTZ Camera

A simple question for the GPS (orientation sensor?)

I'm trying to use  the ardupilot setup to control an unmanned ground vehicle :D:D:D:D:D:D!

I was going through much of the documentation but still couldn't find the answer to a little question of mine.

Does the robot not need to know it's orientation

Looking for help in designing the control system for a quad-rotor craft

Hello all,

I was hoping I could get some answers to questions I have regarding building the control system for a quad-rotor air craft.

I have a spectrum DX5e transmitter and receiver combo and I have the quad-rotor built.

Now for the questions:

1.  I

Does anyone have ArduIMU+Pilot firmware ?

Hi All,

I am working on dynamics model development of my aircraft. I want to use ArduIMU+Pilot as a data acquisition hardware. I am going to disable all autopilot functions and make the board perform measurements and send it down through XBee. In ord

Another uBlox GPS question

Hola Amigos, I'm having issues with my uBlox GPS.  I've taken a lot of time reading the instructions and reading other's posts regarding their problems before deciding to post here.

First off, I built an adapter cable to be able to test the GPS via u-

ArduPilot Voltage connection

In the instructions, it says I need to connect the battery directly to the spot indicated to allow battery voltage to be transmitted back to the ardustation.

I would like someone to confirm that connecting an 18.2 volt lipo batttery directly to this l

ArduPilot manual update?

While I was setting up my first wiring on an ArduPilot last night, I noticed the manual shows Input 1,2, and 3.  The board itseld though, is clearly marked 1,2,3, and 4.  This made me wonder a few things...

1- I assume the newer board can use ailerons

The Micropilot or AttoPilot route?

Hi Guys,

Will this GPS work with Ardupilot?

I was going to get the EM406 1HZ GPS for $60, but saw that this d2523t 4hz GPS is only $20 more. I see that it has a similar connection, and output. I don't know if it will work though, can someone verify weather its compatible?

EM-406a Lockup problem

After successfully getting the EM-406a to parse out data over the SiRf simulation software I attempted to use the standard GPS parsing code for the Adafruit GPS Logger Shield to send data over the serial inputs of an Arduino Mega.  Obviously communic

Which connector for GPS

There gps connectors on both the AP board and the shield. Which one does my EM406 plug into? I have used the shield socket but get no blue light.

Ardupilot and Millswood Engineering GCS

Has anyone managed to get the Millswood Engineering GCS (http://www.millswoodeng.com.au/fd_gcs.html) to work with Arupilot telemetry stream?

I'm in a team to be competing in this year's Australian outback UAV challenge and we'll be using one of their

Mode switch mixing

Can anyone offer some help with mixing across 2, 2 position switches for mode select?  The ArduPilot manual just says "refer to your radio's manual", but when I did, it looks like I maybe can't.  I'm running a JRXP662 for helicopter and airplane.  It

Netbook for ground station?

Having built a 5GHz video downlink, I'm now looking for portable display screen. Rather than spend money on a single-use screen I'm considering a netbook with a USB video capture device. That way, I can also use it as an autopilot ground station.Spur

Arduimu gyros doesn't work

I have just finished soldering my new Arduimu gyros to the board but they seem not to work.

I checked all the contacts, and all the voltages seem fine. but the voltage on the out pin is constant at 1.8V and doesn't change when the board is rotated.

Ardupilot & Arduimu with code 2.5, it works

Hello, here is a version 2.5 using the IMU not the optical sensor and a GPS uBlox.

At the same time I solved the problem of checksum that was capricious, the problem was the failure to manage overflow ck_a and ck_b as a type byte. There were too valu
