Traditional helicopters now supported by ArduCopter2, too!

Check out the firmware loading screen from the latest Mission Planner (1.013). Have you ever seen anything more beautiful??


Yes, APM is the first autopilot in history to support every kind of flying machine out there! (We already covered lighter-than-air with Blimpduino). Thanks to the great work of team…

Considerations for an Official Tri-Copter Frame?

I'm starting to see tri-copters becoming more and more popular, so I'm asking the DIYDrones community if there is any interest in making a tri-copter frame that has interchangeable parts with the quad-copter frame.


I've put together a rough draft of a 2D laser cut sketch of a possible…

Final results of the AUVSI student UAS competition


The results are in, and we have some great reports from the AUVSI student competition. A Paparazzi-powered UAV came in first, and APM made its best showing ever, with APM-powered UAVs in  7th, 15th and 16th place.

sustained rotations : pushing the envelope

This is an update of a previous post, with a link to a report that I promised that I would write. The above plot shows the results of the automatic calibration of the Z axis gyro during tests of methods to improve the performance of attitude… Continue

Note that Marcy vision is our quadrotor's fuselage with a board from an

abandoned ground rover, complete with H bridges, servo headers, & a

900Mhz radio.


So the Logitec C510 has fixed exposure.  Search through the kernel for

V4L2_CID_EXPOSURE_AUTO.  Unfortunately, there's no way to…

Fiberglass MQ-9 Reaper with 2.5m wingspan

This model is big! 2500mm is impressive by any standard, yet the model is very practical, for instance the highly efficient balsa wing is removable for transportation. This model is highly unusual being both a scale model and a purpose built FPV/Camera platform. The Reaper UAV is a development of the Predator and represents the latest in cutting edge military technology, it is also…

Cool amateur UAV effort to film the last Shuttle launch from high altitude

An amateur/educational group called Quest For Stars plans to lift a glider to the edge of space with a balloon to film the last Space Shuttle launch. In future flights, the glider will be then released and navigate home, broadcasting FPV video the whole way.…

A simple INS - the beginnings

I'm building my own inertial navigation system --- one that isn't super complex, doesn't involve fancy filters, yet will provide plenty of accuracy. It's all about purposeful building... designing and building for what it WILL do, not what it MIGHT or could possibly be able to do.

[SOLVED] XBee 868 MHz two ways communication

One of the things not clearly said in the Wiki is that when you set Xbee communication, you MUST define correctly the addresses of the modules, otherwise you'll not get right communication.

After, 8 hours of chatting, writing post forum and headache, I noticed this fact when I tried a range test of Xbee by using X-CTU tool by Digi. One module was in loopback (just connect the DDI to DDO on the planeboard of the Xbee, and, obviously, connect the 5V), and the other one was connected to the… Continue

In development...

I have not posted up anything in a month so thought I should give an overview of what I've designed. Unfortunately I have hit a LARGE snag in that BatchPCB is basically broken for international orders as no shipping options appear and so you cannot buy anything (its been like this since January). 5 months of waiting to produce…
