Snowy first flight with Radian Pro

First of all, sorry for the unexciting video. Waiting on my new gopro so I made do with an old keychain cam. 

Flight went well! I was very impressed with the RTL performance straight out of the box. The Radian displayed much less of a tendency to wander than the 6' Telemaster I had flown with APM before. I will take a stab at tweaking the gains. This first image is just the RTL flight and the next one is all the flight data. 

Before landing, the plane…

How to get your first Arduino-based ground station project on the road

I have been asked a few times now how I got my GCS basics up and running. MAVLink is a rather complicated protocol to implement. The documentation is rather thin and partially outdated... Not an easy thing, if you are no experienced developer...

I'm no pro developer by a long shot. I speak reasonably well C and I did some smaller projects in JAVA. All in all, I can hold my…

Possible solution to getting Jello Free GoPro Hero 3 Black Edition video on multicopters

I'm sure everyone who is into aerial videgography with the wonderful GoPros have struggled with getting Jello Free (rolling shutter) video footage from multicopters. I have tried them all. Using ND filters to lower the shutter speed of the GoPro (worked somewhat but ruined image quality), shot in 720p @60fps but would have preferred shooting in full HD. Tried all sorts of foam and vibration absorption materials, ear plugs, rubber foam mounts, hours balancing my propellers…

Connecting to APM 2.5 via Bluetooth

If you'd like to connect to APM 2.5 wirelessly but don't need the long-distance reach of the 3DR radios, you can use the Bluetooth connection built in to your laptop, along with a Bluetooth module. 

Here's what you'll need to do this:

  • A Xbee-footprint Bluetooth module. Either…

Just another quick technology preview

We are still making some nice progress with the project. I finally got the smallprotocol running, which is a propietary but well documented communications protocol with checksums and stuff for the display. Result: Rock solid performance and no trash on the screen if the Arduino sends too fast or some bits get lost.

At this point goes a HUUUGE thankyou to Pat Hickey who helped me out quite a bit on the mailing list. The MAVLink and other libs are really…

Ladybird autopilot

The 1st flights good enough to get on video. It's extremely unstable, but there is hope. The MPU9150 was the only way to get the sensors small enough. It might also be the smallest thing currently…

Winter FPV at Castlewood Canyon

This is a quick video of a flight after some fresh snow in Castlewood Canyon State Park south of Denver, which was one of my favorite places to go as a kid. This is the first video I've posted using my new GoPro3 White Edition. It's taken me forever to figure out the right settings for color correction, since the raw video from this camera is normally flat…

Android Ground Controller, beta release

So a few weeks ago I started writing a ground controller for Android (using a spiffy mavlink library - see credits).  With the help of a few kind alpha testers, it seems to work pretty well now.

Current features:

  • Direct control & monitoring of ArduPlane/Copter with no PC required.  Just a $5 USB adapter…

Thermopile Arrays

In searching for sensors to use with the Arduino, looking for something new to play with I discovered a 16x4 Thermopile array, a bit of a search revealed a manufacturer that makes a 32x31 array, these may well be within the reach of the hobbyist, giving us a way to add thermal imaging to our…

A few tips for building a hexacopter

I had a blast helping my friend build his hexacopter last weekend. This video includes some tips and tricks. We also had to do some interesting trouble shooting for problem that showed up during ESC calibration that turned out to be a bad soldering job (yep it was my fault!).

Anyway please enjoy a 5 minute condensed version of a fun day building the most…
