Beijing Model / Hobby Expo May-2012
jDrones visited on Beijing Hobby Expo this May-2012. Beijing model expo is one of the biggest in mainland China. There are hundreds and hundreds of people around the world visiting on expos every year. This year was…Continue
Good news: Arduino has released a new version of its IDE (1.0.1) and it now supports ArduCopter/ArduPlane right out of the box. (The previous versions of Arduino required a patched version that we supplied to handle the size of the ArduCopter/ArduPlane codebase, which is considered the most complex Arduino program ever made!)
Here are the…Continue
I'm looking for a platform for basic image processing. Found nice products called fit-pc & fit-pc2i
Does anyone know/use better alternatives for that? It would be great if it could run Linux/Windows.
If you consider yourself to be one of the following, then read on:
1) Those with extremely fast airframes, such as jets or hotliners or the like.
2) Those that have more than the average dollar invested in their electronic packages.
3) Those that are just nerdy enough to just want to know if this…Continue
I'm a big fan and supporter of open source multirotors but this is just too impressive to pass. Too bad it is super expensive and out of reach for most hobbyists. Just wanted to share this with the community and see what they have to say about the the frame, gimbal and about DJI in general.
It’s about the size of a smartphone and about as powerful. It comes with Android 2.3
pre-installed, They’re taking pre-orders and expect to ship in July.

Here is a quick test of the two-switch flaperon setup I whipped up for the EPP FPV from HK.

Align Helicopter APS system features:
1.Semi-autonomous take off / Landing (Activate system, semi-autonomous takeoff into position and altitude hold, hovers in attitude hold with strong holding ability to prevent drifting, suitable for hover and flight…
In the spirit of finally getting around to things, I got the HobbyKing EPP FPV plane in the air, FPV style!
The video is of my 3rd FPV flight, so pardon the less-than-ideal flying skills. I've done a handfull of flights non-FPV, but quite frankly I'm rubbish at flying that way. I suppose that's to be expected since this is the first RC plane I've ever flown,…Continue
UPDATE: They did it!!
For those of you awake right now, Spacex's Falcon 9 rocket with Dragon capsule will be launching from Cape Canaveral, Florida in less than an hour. If successful, this mission will see the first private spacecraft docking…Continue
We had a great time at Maker Faire, which was absolutely packed (100,000+ people). Above is a panorama shot of the 3D Robotics talk on Quadcopter UAVs, which was standing room only! (Thanks to Alan Sanchez and Sam Kelly for the ArduCopter flying and panorama photo taking).
It really takes very little to become hooked on all this UAV stuff... Of course the learning curve for a complete and utter noob such as myself has been immense, but the payoff has been equally so. Being able to send my stock 3DR soaring above a sun-baked vineyard and have it return with a treasure trove of images including one like this, make all the time, frustration and money completely worth it!
Thanks to all of the developers, testers and enthusiasts…Continue
so, we did it :)
it is not first time in history of humanity, but it can easily be first time in estonia. as every other genius ;) thing, it's pretty simple:
- take a multicopter (such as cinestar from freefly)
- take an hd-camera (such as panasonic gh2 or sony hdr cx350)
- take an hd-video encoder (such as teradek cube)
Get yer Dev Kit while its hot.
What technology does leapmotion use (is it imaging? a theramin?)
I'm not sure, but they promise uber-kinect like performance ; ie minority report handwaving;
but ultimately, if it creates a depth map at that size, shape, and cost…Continue
Our Autonomous Vehicle Competition is less than a month away now (June 16, 2012 at SparkFun Headquarters). It's shaping up to be an awesome day! We've created…
A LiPo battery consists of multipe cells. These cells deliver approx. 3.7 Volts. A 4S LiPo would therefore supply 14.8V.
Apart from the cells, a discharge rate is defined by the letter 'C'. Most batteries cases say something like "25C to 40C" discharge rate. This means that 25C is the nominal discharge rate…Continue
Motors come in two variants: Brushed motors, which have small brushes that switch the power through the coils, and brushless motors, which need an external controller to do the switching for them.
Brushless motors are usually more efficient, can handle higher speeds and torques, can handle huge amounts of power, and are longer…
At Maker Faire, Chris said auto-land is a hard problem. While I don't have much to contribute to that yet, I did want to try deploying a ballistic parachute mid-air to bring a plane down. A few others have shared successful parachute systems before.
