Two-Stage Copter

This video was just posted by EndOfDays, a well known figure in the photo/video multicopter scene.

And for the record, let me just say that some people have WAY to much free time. :)

ZeroUAV YS-X4 teardown

So no completely trusting that Santa had gotten the message, I made sure that there at least was one present under the tree that I would like.

The YS-X4 is the latest multi-rotor autopilot from ZeroUAV, and their entry into the…

NASA Morpheus lander (rocket quad) - crash and burn

I guess even the big boys have to try a couple of times before they get it right. :)

Confessions of a gadget addict...

I am probably going to get hate mail for this, but a clear warning to any future addicts needs to be made. So here goes.

I was doing some spring cleaning and those darn DIY gadgets just kept on coming out of the woodwork. I knew I had a lot of stuff lying around, but this time I even surprised…

Watertight Android tablet. The perfect groundstation?

Some of us, do not live in California with 300+ sunny days in a year, and have to cope with rain and bad weather. The new watertight Fujitsu Arrows Tab looks to be perfect for such days.

CircuitLab - Online electronics simulator

I just discovered CircuitLab, a online electronics simulator. I haven't had time to play much with it yet, but it looks very promising from what I have seen so far. Especially considering that they just launched the site.

Full scale octocopter

 

There has been some posts lately about people building and trying to fly full scale multi-copters. Following this trend I though I should share the most successful project I have seen so far. Mr. Ivoprop over at youtube seem to have a fully working octocopter design built around…

Very interesting technology with lots of possibilities. The demonstration subject should also be well known for most of us. My own limited testing show that quality of results vary greatly. Has anyone tried using photos taken with a UAV…

Crawler1 - Land based rover

So, having spent the last couple of years experimenting with UAV systems I felt the need to try something that would stay on the ground. I have been fascinated by rock crawlers, the latest RC off-road trend. They seem the be the ideal platform for a land based all terrain rover system. Traction and maneuverability is…

Early stages of a TiltCopter



Today everybody and their dog seem to be working on a quad project. And with my own quad having reached a relatively mature stage with stable flight some time ago, I thought it would be nice to try something different.

So inspired by the full-size Osprey tilt rotor design I just started an experimental duo/tilt copter build. Frankly I am far from sure…

Long range R/C control and two-way telemetry



After having had some performance issues with 2.4ghz Xbee modules I just finished up a quick project for long range two-way communication. The system is based on HACCOM HAC-LM96 500mW 433mhz 9600 baud radio modems. Range is 2km (1.2 miles) ground level, so the system should be good for really long range communication when the plane is up in the air.…
