Slovenia FPV Vacation

A couple of friends from Slovenia invited us to the wonderful Triglav National Reserve. We got filming and R/C flying permits for the day we were there, slept in a beautiful and very peaceful hut in the middle of the national reserve, and played a little bit with our toys :) aufmschlau.ch was kind enough to put together a video of the weekend. Enjoy!…

German Multicopter Lifts Human Pilot


Love the yoga ball as a soft landing device, can't believe the pilot trusted his life to an RC controller though and he never had covers for all those props which would have sliced him up like a blender if things went pear shaped.

Awesome stuff, just totally jealous as we are…

Miga motors nanomuscle : servo substitute?

I was looking for a parachute ejection system for one of my small UAV and I found the miga motors nanomuscle. Cheap  SMA system linear actuator (less than 10$ unit), I was thinking about using some instead of the servos on UAV.

Annual Public Service Announcement

We have had our first snow storm here in Colorado, and the furnaces are definitely running, so it seems like a good time for my annual ESD Public Service Announcement.


What is ESD?  Electrostatic Discharge!  That little spark you sometimes get when you touch a light switch or some other grounded object.  Electrostatic discharge is always an issue when working…

Trex450 loiter testing using Arducopter 2.0.50Beta

This video is of some loiter testing I did this morning of my Trex450 running the latest arducopter code, 2.0.50.


If it were a quad I might not be super happy with the results but for a traditional heli, I think this is a pretty good performance.  The altitude hold is very solid using…

3D Robotics
Control an OWI Robotic Arm with Arduino

This doesn't have anything to do with UAVs, but I did use some of what we learned with ArduPilot in this fun robotic project, which I thought I would share with you all.

My daughter has a history project to do on the Ford Model T and the origins of the production line. Given that…

Successful Maiden Flight of the GeekStar!



Successfully maiden'd the Geek Star this week! (Geek Star = MyGeekShow version of the Easy Star) It flew very, very well, better than I anticipated. Its still a little tail heavy due to servos being placed so far in the tail, but that can easily compensated for.


I'm going to use the Easy Star's wings for a while, but will eventually move to a total scratch built airplane.


It flies pretty solid at half throttle and can really…

Warning! Loctite eats plastic

Maybe this has been posted before, but I was unaware of this.

I have been assembling my quadcopter and as advised have used red loctite # 271 to lock the metal nuts and the prop mounts.

I have used it all up and bought some blue loctite #243 and have used it on some of the nylon nuts last night and have just noticed today that it has eaten away the part of the…

Another contribution: better CLI error messages

Here is another thing that I did - 9) CLI – message when bad command entered - Add a message so users know when they have entered an invalid command.


So instead of just swallowing wrong commands it will be something like this:


ArduPlane V2.24] blah-blah-blah

Unknown command! Please try again.

Type 'help' to see…

Google to charge for Maps API calls.

So it looks like one crucial element in the Pigeon Post set up may have got a little more expensive.  The Guardian is reporting that Google will now be charging users who make more than 25000 API calls a day.


The pricing is pretty reasonable and I'm sure the…
