Sony RX0 for $700.00 looks way better than GoPro

The new Sony looks way more Pro than GoPro

The New Sony RX0 looks like a really Superior camera for our use.

Probably too much to ask to make it work in our old Solos, but maybe with a Cube - who knows.

1" image sensor and high speed HD and shutter and zero to infinity focus and  pretty much distortionless.

Also has uncompressed 4K…

Nvidia TX1 SE kit a steal at $200.00

Hi all, long time no post, but this is too good.

Those of you doing development want this.

At $200.00 it is 3 times cheaper than the TX1 normal development kit/board and the only difference is no camera module, but any USB camera can be used.

Not quite the poop of the TX2, but for object avoidance or even navigation, by far the best / cheapest deal…

Sony FDR X3000 4K Action Cam

Hi All, Sony has actually given us something to think about.

The Sony FDR X3000 Action Cam has 4K resolution, but for our use, the BOSS active optical stabilization is the important part.

Really, really stupid idea of the month, maybe the whole year!- - Drone attack Eagles!

I just saw this on our local news and was surprised nobody else had posted it here yet.

Easily the truly stupidest idea I have ever seen - Dutch Police train Eagle to take down drone.

Better than the UnAmerican Eagle in the Our Man Flint Movies (that dates me a bit I'm afraid.)…

FAA/DOT UAS Registration - A Very Short Window to Comment

Hi All,

We have a very short window of opportunity to comment on the FAA's proposed registration process.

I have sent in the following comment which you are welcome to copy, edit, do whatever you want with, but I think it realistically presents a decent case for moderation and common sense on the part of the FAA.

(Yeah I know good luck with…

Great deal on a 3 axis gimbal with Alexmos controller

Just had to tell all of you about this $59.95 three axis gimbal deal on EBay:

This seemed like a great deal and looks to be identical to DYS Gimbal on Hobbyking which is $200.00.

I got one and quality appears excellent though I haven't tried to use it yet (I will probably get another.) 

I'm planning on converting to a Storm 32 for a laser…

My thoughts on the state of affairs.

Recently a local radio station asked me to comment on an interview relating to the current status of "drones".

I am enclosing the letter I sent to them declining phone interview for the reasons specified, but putting my "opinions" in writing instead for them to use as the wish.…

GoPro 4 is Here - Sort of!

GoPro is finally announcing the new 4 Silver and Black:

It , of course has the new 30fps 4K and - not surprisingly costs $100.00 more than the last one so now $499.00.

Probably using the new Ambarella 9 chip, but no mention made of built in electronic image stabilization which is a feature of the Ambarella 9 chip. …

New 1 at a time ESC calibration method for PX4 or Pixhawk

One of the Problems with the PX4 / Pixhawk is that it uses a PPM-Sum receiver which when so configured may not work at all for the normal receiver based method of one at a time ESC programming.

And especially so for 4 in 1 ESCs.

The one at a time method I have developed uses the Wikis normal all at a time method that goes through the Pixhawk to the ESC…

BeagleBone Black available - if you're quick.

Hi all, Beagle Bone Blacks are available at Adafruit this morning.

I wouldn't ordinarily put an Advertisement for a product as a Blog but as you may or may not know, Beagle Bone Blacks are seriously hard to come by.

Everybody is out of stock all the time, except a fewy unscrupulous dealers who jack up the price - a lot.

Adafruit has a notify service…

I Really Need help solving a problem for all of us!

We have a great new Wiki / Manual which is actually being I think very helpful for all of us.

But there is a Huge - Seemingly Intractable Problem. At least in my estimation of things:

No the Iris isn't the problem, It's a really great 3DR copter, probably the best one available for the price - period.

Mostly its just here to get your…

New Wiki Advanced Multicopter Design Page

Hi Everybody, I have added a new "Advanced Multicopter Design page to the Wiki.

It covers a lot of concepts in Multicopter design both for selecting components and frames and in designing your own if that's what you might really want to do.…

Some MultiCopter Design Thoughts.

Hi All, Just pulled this image in from SUAS News (Thank you Gary) to illustrate a few really good concepts that it incorporates and talk about better Multicopter design a bit.

This copter has a lot of things right and is really a study in design excellence.

1. Most obvious is a sliding ball full enclosure camera Gimbal, very pro and really…

And Now for Something Completely Different - APM:Bot

Ive been wanting to build a Hanging Pendulum robot for the last 30 years

Technology (and inexpensive consumer parts) finally conspired to let me try and realize my dream.

Inexpensive 500 watt 48 volt 26" Chinese brushless bicycle wheels form the basis of my bot.

And the chassis is constructed from T6 aluminum plate and extrusions with…

Meet Flip a REALLY Tough little Quadcopter

Hi All,

Some of you may remember a while back I put in some posts on F3330 and F450 DJI FlameWheel QuadCopters detailing construction and operation.

I really love those little FlameWheels for delivering many hours of fun and resisting my every effort to destroy them.

I thought I'd try and kick it up a notch this time.

Something even…

New (APMcopter) Wiki up and operating!

The new APMcopter Wiki is up and running!

As you probably know, some of us have been hard at work trying to bring up a new Wiki for the copters, planes and rovers.

I have recently completed installing the vast majority of the pages from the Old ArduCopter Wiki into the new APMcopter Wiki/Manual.

And I have produced a Drop Down Menu…

New ArduCopter, ArduPlane and ArduRover Wikis Operational (provisionally)

New ArduCopter, ArduPlane and ArduRover Wikis are Operational (provisionally)

The old existing Wiki(s) are no longer getting updated on a continuous basis so you need to start using the new Wiki(s).

During this transition you will need to use both of them (although for the PX4, the new one is the only way to go.

The picture above is of my new F330…
