My First FPV, Simpson Desert in Central Australia (GoPro processing settings added)

This is a couple of flights from my holiday that I made my first quad copter for. My wife and I (and two kids under 2) were planning a 2 week four wheel drive trip across the Simpson Desert in central Australia. For those not familiar with the Simpson Desert it is 550 km of desert, 1100 sand dunes to cross, and 3000 km round trip. The…

Foam Pad "launch pad" eliminated takeoff instabilities in Acrobatic and Stablizer Modes

 

Summary: Takeoff from a foam pad on top of dry grass/lumpy lawn alleviated instabilities experienced when taking off from the dry grass/lumpy lawn.  No gain changes made to the 3DR ArduCopter code, using the "factory" settings for Stabilizer and Acrobatic…

If you're using Sharp IR sensors on ArduRover, watch out for asymmetry

If you're using the Sharp IR sensor as an obstacle detector on your ArduRover, you should know that it doesn't see left and right equally. Here's some good analysis on its real detection pattern. So you might want to tilt the sensor a bit to the…

Return to Launch flight mode in SmartAP

I would like to share the latest SmartAP autopilot progress. As well as GPS Position Hold mode (introduced ~1 month ago), now it has Return to Launch flight mode. No matter wherever the copter is, just switch to RTL and it will come back to its home position autonomously. You can watch the video of Return to Launch test…

Flying at No Mechanical Energy Cost: Disclosing the Secret of Wandering Albatrosses

I found a very interesting journal article about the flying techiques of albatrosses. It describes their ability to soar extreme distances by using the different windspeeds over the open sea, similar to the flying technique of dynamical soaring we use for hanggliding.



It's in PLOS One …

The end of drones in Belgium?

Life is becoming pretty difficult for drones lover in Belgium: apparently the department of air transports in Belgium has either approved a new law or a new interpretation of an old one, which equiparates drones to any other RC aircraft: under that interpretation, drones can only take off from approved terrains, and can only go maximum 400m from the RC club, and must stay at more than 200m from any…

Self-built flying wing

One of the glass fibre arms of my quad shattered after repeated hard landings on a hard-wood floor, so I have some carbon fibre replacement arms on order. Meanwhile I thought it would be fun to experiment with foam cutting and trying to build a plane from scratch. With inspiration from MyGeekShow I decided to build a…

Now I can time (approximately) flights of a South Carolina Arducopter

 

It took me a little while to learn what most of the switches and buttons on my DX6i could do. This past weekend the Trainer switch was assigned to start the timer in a count up mode.

Behold!

With my EFlite 30C 11.1V 3200 mAh battery almost 7 minutes of mostly hovering flight was achieved (no…

ACM at the AVC

Image: 1st Run

 

AVC was great fun and even though I went for broke on the last run and lost my copter, it was well worth it. I learned a lot about copter navigation. The latest code includes all of the updates, which is being tested now by Jack Dunkle.

 

Run 1 went really well. In turn 1 you…

Multicopters welcome at the Sparkfun Autonomous Vehicle Competition again!

Good news: After banning multicopters this year because of space/safety concerns, Sparkfun will be moving the aerial competitions to another location next year so all vehicles can participate. 

At this point, you might be asking yourself, "Self, how can they possibly allow unlimited…

Filming a mountain bike race using FPV/Arduplane

I went out to Citrusdal to try to film a mountain bike race using FPV/Arduplane. It went really well and it could've worked, but I decided to relocate at the last moment and triggered RTL forgetting that I launched from the valley 350 meters below, so it dropped altitude while still over the mountain, smearing my Skywalker along a cliff face...

 

But we had fun…

HackHD: FPV Source + 1080p recording

My interests tend towards high-altitude balloons, but I find that there's more than enough overlap in the technology here to keep me coming back (in case you haven't noticed, there's some darn cool stuff that happens here).  So far, I haven't had a reason to actually post to the blog, but this might be relevant enough to justify consuming your time: a camera that is…
