How come in the following PUB module that I am executing via a separate COG, The Rx Inputs that I am receiving for channels 1-4 and 6 stop when I flip the gear switch (channel 5) ?repeatstackRxPass1 := bs2.Pulsin(RxInput1, 1)stackRxPass2 := bs2.PULSI
Read more…Guys, I have a Picopilot NAT and am trying to get it to work with Windows Vista and my HP Pavilion dv2000 laptop. The laptop doesn't have a serial connector, so I am using a USB-to-RS232 serial adapter with a Null Modem adapter, but despite every pos
Read more…Was very disappointed by this nugget http://diydrones.com/forum/topic/show?id=705844%3ATopic%3A25130which killed our hopes for EasyStar ecstacy. So many junk parts are emerging from Vicacopter that a throwaway UAV based on the EasyStar & GPS was a go
Read more…Hi Chris,I have been looking at your basic stamp code and I think it is all starting to make sense to me finally! I have a question relation to the altitude control, I understand that if the UAV is + or - 10 Meters away from starting altitude it will
Read more…I've heard different answers from different sources on the exact capabilities of GPS technology (specifically, the Parallax GPS Receiver). One thing I was wondering was about the heading information the GPS receiver outputs. I understand this is done

Read more…I have an emergency project and I need your help. I am putting a presentation together for the fire department where I work on UAVs. I need info or links as to why UAVs are better than manned vehicles. Specifically, I remember some aircraft crashing
Read more…Hello everyone!Just got my board manufactured a few weeks ago, so it's time to post a little description of my ongoing project here, so this is it:
Here is what's embedded onboard:Processing elements:- CPU: Microchip dsPIC33F256 at 40Mhz, allowing a p
Hello, my team and I at Purdue University are planning to build a UAV that will be able to guide itself with GPS and a digital compass to way points. None of us have experience with R/C planes. Initially we were planning to use an Easy Star because i

I feel really dumb asking this, but I swear I've been looking all over the web and I can't find a definitive answer. Every website I find tells me how to convert from degrees/minutes/seconds to decimal degrees, but the Parallax GPS receiver outputs i
