Handy resource




Good for having on GCS google earth screens, if its accurate mind! The South African version is not very comprehensive.


Still you all have a sectional for the areas you fly so you would be able to…

The AeroQuad



I know this is not strictly a UAV but because this is centre of the universe for things Arduino flight related and there have been some very cool posts about Quads lately (it is also one of my passions), I thought I would post about an Open Source Arduino based Quad platform in case people are not aware of it.



I have heard of the project in the past but never really spent any decent time looking at it until today, it certainly looks very good and appears to… Continue

Spam fighting on DIY Drones

If we do our job right, most members here will have no idea how much spam we fight here every day. Normally it's not too much, just a dozen members who have spam links in their profile. But over the last week, DIY Drones, like most of the other networks hosted on the Ning platform, has been hit by the biggest botnet attack we've ever seen, with hundreds of fake member accounts being created every day to post Canadian pharmaceutical ads. The graph above, from…

No Baro altitude filter for ArduPilot

I wrote down a napkin sketch of an altitude filter a while back and finally got around to testing it in the simulator. I designed it to improve the sensed altitude of the ardupilot. It is based on a fixed gain observer model and shows very promising results. The idea is to use the "lagless" airspeed sensor to give you a less noisy lagless altitude estimate. Enjoy!

K_alt = -0.01;

avg_aoa = 0.52*(pi/180); //alpha =…

Project Andromeda Ground Station



The above picture shows the Project Andromeda ground station circuitry. You can also see the DNT900 from RFM. I believe there has been some interest on this radio in the DIY Drones community and once I finish the construction of the autopilot I will be able to give a recount of my experiences with it. So far, however the radio seems to be extremely capable (especially compared to the…

Coyote - small UAV from big guys









Found this interesting - small UAV from BAE Systems



"The Coyote is a small, electric-powered unmanned aircraft system. Initially designed with funding from the U.S. Navy, it weighs only 13

pounds and has a 58-inch wingspan. Once deployed, it can cruise faster

than 60 knots… Continue

Hand made GPS receiver.

I had bought MStar GPS module for UAV Board. But the datasheet is not very clear for this one. So I have made a test board for test it.



It is fast to get location when power on.(32 sec), but I confused the date of GPS is wrong. Although I just want the location, altitude, direction and speed information. XD…

hi folkz



something is missing in the arduino-world ;-)

yeah, a handy way from the bredboart to a eached shield.

Blimpduino update: code and documentation tweaks

A quick update on Blimpduino: We've temporarily run out of stock at the DIY Drones store but there are plenty at the Maker Shed, where you can buy them at the same price (it's a very cool store--spend some time there!). We've got some components incoming, and I expect to have them…

Micropilot only now gets a 4Hz GPS



We don't talk much about the older commercial autopilots here much, but I was amazed to see the above in my inbox yesterday. The Micropilot 2128g, which is a staple with the university crowd, has only just now upgraded to the 4 Hz uBlox GPS that we in the open source world have been using for years.…

Tilt-compensated heading algorithm



Perhaps it's some sort of cruel joke we're not in on but everything I've been able to find on the Internet about tilt-compensated headings from magnetometers leads to this paper [warning, it's a PDF]: http://www.ssec.honeywell.com/position-sensors/datasheets/sae.pdf…

Ardupilot beta

I just made some changes to the 2.5 code to address some issues of compatibility and general usability improvements.


If you use throttle input, you'll be able to try flying without the Remove Before Fly pin. I had to restructure the GPS reading routines to do this. Now the system goes immediately into the main control loop. This has a few benefits:
  • The GPS led blinks when GPS fix is lost instead of just turning off.
  • You don't need to remove the…
