RiteWing Zephyr II + APM maiden flight



Had a great time maidening Andreas' new RiteWing Zephyr II with the APM.  The Zii flies very nicely, and works well with APM.

We flew in manual, stabilized, fbw-a, and auto modes.  We reduced the default speed from 45 to 35, which gave a nice smooth flight with a comfortable airspeed for our flying site.

There's some onboard video as well.…

Could domestic drones spur tougher privacy laws?

MK Frame + Photoshipone Camera mount assembly

I decided to put the camera mount and frame together to get some sizes on the boards that hold the APM and flight electronics. Obviously being a MK frame, its suited for the MK boards, with regard especially to the MK escs.

Im going to have to make a small plate for the PDB, then two plates above for all the other electronics. Also I had to add silicone to the ball mounts to make them stiffer for an 800g camera.

Here are the pics:…

My DIY Tri

Inspired by this series of DIY videos, and a little wary of over-spending on yet another silly flying machine, I've decided to have a go at building my own Tricopter. The idea is to see just how cheaply I can build the whole thing from start…

Magnetometer again







It turned out to be an 8975 instead of an 8973.  By some contact lens malfunction or erroneus Goog search, we thought it was an 8973 all year.   The 8975 has a completely different pinout than the 8973.  The power pins were shifted around.  An…

I know how I am spending this weekend

Woke up this morning and saw my shipment was sent...20 min later fedex at the door. I just received my new APM 2.0. One of the perks of living in SoCal is fast shipping from DIYDRONES. I got 2x so one is going into sim mode and the other one is sitting on the bench waiting for permission to board my…

Georeferencing pictures

Here is my memo: How to save gps-coordinates to picture files with Geosetter program. The coordinates are saved to the picture exif-data, and these go with picture all the time. In exif there are already data from camera model, exposure time, lens focal length etc, now we add there gps coordinates.

For example here is…

Free AI class possibly has Drone applications

I am just finishing the Intro to Artificial Intelligence free on-line class from Stanford.  There are probably many helpful things in this wonderful class taught by Peter Norvig and Sebastian Thrun.  But I have to mention the Particle filter algorithm that can locate a vehicle in a previously mapped environment quickly and with minimal computation. …

Details on how Iran may have used a GPS override spoof to capture US drone

[I'm applying the sysadmin privilage of making an exception to our usual no-military rule here, because the technical issues are sufficiently interesting].

Apply the usual skepticism about the claims, but there's something plausible in the following. As I understand it, the…

Wide field 4D optical flow odometry using Arduino and Stonyman image sensor

 

I've been working on a new version of our ArduEye using one of our "Stonyman" image sensor chips and decided to see if I can grab four dimensions of optical flow (X shift, Y shift, curl, and divergence) from a wide field of view. I wirebonded a Stonyman chip to a 1" square breakout board, and attached it to an Arduino Mega256 using a simple…

New GoPro lens protection product by fpvmanuals

FPV Manuals Introduces "LayerLens" -- Exposed GoPro Lens Protection

The case that comes with the GoPro camera is beautiful, sturdy, and water tight, but it weighs about 100g and the included mounts make the camera stick up over 1″ with the overall surface area growing by a good amount. As a result, many UAV, FPV and aerial videographer pilots mount…
