Arduplane - Altitude on autopilot mode

My Arduplane (2.73) + HK Bixler performs well on autopilot missions with regard to hitting waypoints in lat/long, but sometimes the altitude can be way out.I made some anti vibration modifications, and shading of the PCB from sunlight, which improved things. But is still can be a bit out - especially on the first few waypoints when climbing at the start of a mission.Is the WP radius setting in flight planner in 3 dimensions (i.e. set to 40m is that in lat, long and altitude?)See More

Welcome to DIY Drones!


This is the home for everything about amateur Unmanned Aerial Vehicles (UAVs). Use the tabs and drop-down menus above to navigate the site. (About us/Site rules)

This community created the Arduino-based ArduPilot, the world's first universal autopilot (planes, multicopters of all sorts and ground rovers). The APM 2.5 autopilot hardware runs a variety of powerful free UAV software systems, including:

  • ArduPlane, a pro-level UAV system for planes of all types
  • ArduCopter, a fully-autonomous multicopter and heli UAV system
  • ArduRover, a fully-autonomous ground-based vehicle system

I'm new to all this--where do I start?                    Are amateur UAVs legal? (yes)

How to succeed without really trying

Posted by Glenn Anderson on June 19, 2013 at 6:00am 25 Comments

My quad is flying better than it should.  I almost feel guilty.

I slapped together a frame in a few hours.  I use cheap props mounted on long shafts with cheap collets.  The motors are not precisely aligned to the frame.  The props are not balanced perfectly.  Motor centers form a rectangle not a square.  APM is strapped to the frame.  I never bothered to calibrate compassmot.  CG is not in the center of the…

Printing (tiny) batteries

Posted by CrashingDutchman on June 19, 2013 at 4:33am 0 Comments

Novel application of 3D printing could enable the development of miniaturized medical implants, compact electronics, tiny robots, and more. It will probably take a while before this will be used for the hobby markt, but I though the story is nice enough to blog about it.

3D printing can now be used to print lithium-ion microbatteries the…

DIY Samsung Trigger for APM

Posted by Jeff Taylor on June 18, 2013 at 5:06pm 3 Comments

20130618_153028

In this post I’ll describe how to make your own cable to trigger the Samsung mirrorless cameras NX20, NX210 and NX1000. We’ll be using an ArduPilot Mega 2.5 to do the triggering but you can use any Arduino or even a soldered push button.

What you’ll need:

  • Any 2 or 3 wire cable – I use a 30cm Futaba servo extender which I cut the female end off…
