"Oh, I am using a standard patch antenna on the GPS just in case people were wondering.

"I have done testing on this as well for anyone who is interested in the performance of a Venus GPS at 10Hz vs an SCP100 Baro. I found the GPS was very unreliable when it first locks on and when it is stationary."
"Hey guys, been away from the computer for a while. Thanks for your input. Ive decided to order in an ET-STM32 Stamp micro. I realise that I could go with the Mega but this micro comes with 16 12Bit ADC's,a few DAC's, 5 USARTS and heaps of other…"
Hi guys,I finally have my IMU up and running and outputting all the data I could ever possible want at 50Hz. The next step for me is the autopilot side of things. Currently the IMU outputs its data over standard UART. This means that my other micro…
"Hi Doug, I though that two bytes were able to represent numbers up to 65,535? my rates dont exceed 600degrees per sec so 600*100= 60,000 which is less than 65,535. Or is my problem that it is a signed number? does this mean only numbers between…"
Hi Guys,Today feels like very slow progress. I guess its the end of the week and I'm not thinking straight. I have a question regrading the binary Message protocol used in the main loop in ArduIMU. I am trying to send the Gyro Rate values through to…
"Sorry, should have done the calculations first, 3.3V/1023 = 0.003226, I am getting 381 so 381*0.003226 = around 1.23V. So it seems correct. Can I ask why the Gyro is not centered. It seem like it is more sensitive when rotating clockwise than…"
"Hi Ryan,
Thankyou for the reply. I think it might be some sort of hardware issue or problem with the analog reference now. On a 10bit ADC it is my understanding that the gyro when still should return a value close to 512 (1.23V). I tested this on a…"

Hi guys,I am using ArduIMU as the sensor module for an autopilot I am building along with the wonderful open sourced DCM code. I found that when I print the ToDeg(Gyro_Vector[i]) from 0 to 3 instead of getting values from -300 to +300 as I expected…
"Hi, so far I have not tried the DGPS function but I am getting position updates at around 10Hz (havent tested that but it is dam fast!). The module is easy to use and I would recommend it. Hope this helps."
"Oh your right. Ive ordered one of the rubber gaskets to put over it. Thanks for that, very helpful. Ive been flat out with other stuff lately but ill upload a new set of test data at some point so people can see how accurate these things are. Far…"
"Hi Dale, I have read the data sheet 100 times now and am positive that I was reading the sensor right however in my research I came across a code example by VTI written in C. This morning I ported that code to arduino and found my pressure readings…"
"Hi Dale,
Thanks for such a fast response! I will have a look into the clearing of the operation register prior to setting High Precision mode but the DRDY pin is definitely pulsing at around 2Hz which makes me think the code is working correctly in…"

"I should have put a space between those two links. They are separate links to an excel document and a .pde file.
Cheers,

"Hey there Dale. I am currently working with an SCP1000 pressure sensor to replace the GPS altitude reading. I was wondering what sort of results you were getting from the sensor. I have mine in High resolution mode but Im not happy with the noise…"
"Hi Dave,
I am working on a similar project to you. It sounds to me like you got some good answers from Paul however the rest of us cant see them :) I was wondering If you could post what he sent you.
Cheers,
Will"
