Warning: Spread Spectrum R/C and 2.4 GhZ video downlinks don't mix!

In a comment on a thread at right, David Albert makes an important point about frequency clashes between spread specturm radios and 2.4 Ghz video downlink systems, such as the RangeVideo and Black Widow AV setups that we use. If you haven't been following the chatter on aerial photography newsgroups, you might have missed this (as I did). This info may save your…

Micro UAVs may be better terror-preventers...

I hope we can all contribute to the Anti-Terror war, by building UAVs, sending them into the DOD and having them take consumer research and make it into something that will protect us in return forn our troubles...

I certainly will donate some of my butterflies...

Is this the miracle chipset that's going to make DIY drones easy?

Analog Devices is about to start selling a very cool-looking device: a small box that combines three-axis gyros with three-axis accelerometers, along with an embedded processor to massage all that data and deal with calibration and drift issues. Called the ADIS16355, it will retail for about $300, which isn't cheap, but when you consider what it would cost you in time and money to duplicate that… Continue

Modding the Nitro Models 4-channel Predator

As I mentioned, I totaled the first Predator UAV, due to the combination of an underpowered motor and the marginal controllability of that design's V-tail-only steering. I spent last weekend replacing… Continue

MY UAV project

Hi everyone, I am running a student satellite project in Pakistan. . Now I want to start a student UAV project. My aim is to develop an agriculture UAV which can monitor SALIN water in Rahim Yar Khan which is major issue for the farmers in the region. Can anyone help me with documentation for the projeect.

Using Pict'Earth for image processing

Now that we've got several UAVs running well, it's time to show what they're good for. Aerial photography is fun, but it's not really useful unless you can cover large areas and integrate the imagery into Google Earth. I've been stitching together images optically and… Continue

How to mod a Multiplex EasyStar

I was reminded by the Pict'Earth guys last weekend that one of the best all-purpose planes for carrying cameras, GPS recorders and any other sort of equipment you want to test is the Multiplex EasyStar, a virtually unbreakable powered glider. Because it's made of…

Imagery is everything!

I have joined this group in the hopes that I will be able to learn more about UAVs. I would like to be able to utilize them in search and rescue. Often we have no good imagery or even maps of areas that we have searches for lost people. It would be great if we could get imagery from a UAV and make it available to rescue personel to assist in search efforts.

What model remote control extend range to 5 miles

me and my college friends built small Glider UAV with real time video camera transmission. but my remote control works only visual range. We intend to extend the uav range to 5 miles with the help of Autopilat and ground control software. can anyone help me to chose the extended range remote control. (what model RC and where can i buy this things by online or anywhere in europe.)

SOOn i will post my entire UAV project in website.

UAV fly-in report

We had our amateur UAV fly-in (the world's first?) on Saturday at the Alameda Naval Air Station. Along with my own 4 UAV's, Adam Williams brought his fully-autonomous-in-training heli, the Pict'Earth team was there with their Nokia N80-carrying Easystars, RCAPA's Patrick Egen brought a nifty camera-carrying slowstik, and we had a handful of other observers, along with the PBS film crew.

Since this was done mostly for the cameras (which can't… Continue

Can open source be giving comfort to the enemy?

2005543901635491116_rs I'm posting this because I feel honestly conflicted about something that's come up. As readers of this blog know, one of my side projects is making Unmanned Aerial Vehicles ("drones") and the technology that

goes into them. Everything I do is open source, and I share much of it here. There are also loads of other…

Hi every one i am a newby in this site. can anyone suggest me to make UAV for the RC and video transmission range of 10 miles. And good quality video camere with maximum zooming facility.

Traveling with your UAV

Here's a tip for you is you are traveling with your UAV using our nations airlines: Be Prepared and call ahead.

I have traveled a few times with my modified EasyGlider and FPV/UAV kit without incident. But on these early trips, the TSA did not feel it necessary to open everything up. Not so on my last trip. I returned home to find my kit in significant disarray and several items damaged. Without going into too much detail here (see my rant on RCgroups… Continue

50,000 page views!

In the three months since I created this site, out traffic has steadily grown as word got out. Now we've just hit our first milestone: 50,000 page views. We have 80 participants, who have done everything from writing a blog post or uploading a video, to just submitting a comment.

How big is the natural audience for a site like this? Well, by my estimate the biggest amateur UAV community, the RCGroups UAV forum,… Continue

Testing heading-hold gyros

Details on how to build the Lego autopilot

UAV mission over the Googleplex

This weekend I was at the Google campus in Mountain View for the SciFoo scientific conference. My session was on using micro UAVs for mapping and scientific sensing, and I thought it would be fun to give a little demonstration. What better than a UAV mission over the Googleplex?

This was cool for a number of reasons. First, you may have noticed that the Google campus "satellite" view is much higher resolution than almost any other imagery on Google maps. (The way you can tell is to…

In the Spring of 2006, the Los Angeles Sheriff's Department began flying small spy drones to track suspects. Weeks later, the drone was grounded by the Federal Aviation Administration. Top cops are… Continue

Want to be on a TV show about amateur UAVs?

This October Wired's going to be

starting a prime-time show on PBS called Wired Science, which will have

a national audience of about 6 million people per night. One of the

episodes is going to be on non-military UAVs, with a focus on the

parallel evolutions of the pros and the amateurs.

We want to film a number of amateurs (including me) flying their UAVs

in the San Francisco Bay Area sometime over the next two weeks. If

you're in the area and would… Continue
