The VULTURE System - Versatile Unmanned Lingering Terrain Utilization and REcon

A semi-autonomous civilian UAV system designed for hunters and fisherman. The current

project is called The VULTURE System (Versatile Unmanned Lingering

Terrain Utilization and REcon ). It will be used to help hunters and fisherman find

game and schools of fish as well as to find the best areas to hunt…

Telemetry App

I went to the first Bay Area FPV fly-in, met some people with really nice setups.  One person was using the iTelemetry app, from Immersion RC.  You can see he didn't quite make it back to the field (ran out of power), which could have been a pretty serious thing since we were flying in a hayfield and the plane was totally…

3D Robotics
Demo showing how much centripetal error an IMU has without GPS or magnetometer

In this demo, Pat Hickey from Invensense does a demo on a turntable showing how much error you can expect from an IMU (in this case the MPU 3000 using the onboard Kalman filter) in a turn if you don't have a GPS or magnetometer to correct it. The answer is less than 10 degrees at .2G (12 inch turntable turning at 33rpm), which is a reasonable guess of what a plane would experience in a prolonged turn. 
This is relevant because the forthcoming Invensense…

OSD, object tracking and (possibly) optic flow on the cheap?

Ran across this today:

It's a dedicated video (PAL or NTSC) Arduino shield with passthrough capabilities. Nothing fancy, just a sync separator and some passive electronics. Obviously, it needs to be mated with an Arduino (additional one, alongside APM, of course), but it's plug and play and comes with a neatly put together library. Question is, can this + Arduino physically fit an… Continue

Build new Quad + frame

After the crash on yesterday I again rebuild the frame using new 12mm aluminium square pipe with same length of 14inch or 355mm with 10x4.7 props. Built the frame and mounted the motors and electronics. Reloaded the software with 4.5 + reboard firmware.


During the test it seems to be good. Trying to achieve a hover vehicle by adjusting the EPA and trims. Most of the the part did work well. But as soon as I finished testing I switched off the Tx thinking that I unarmed the…

Well, to work in a spin stabilized mode, Marcy 2 would have to spin a

lot faster than a 3 channel coaxial copter can.  Without spin

stabilization, a $40 Syma S107 or a $25 Sky Invader didn't matter

because either way, we needed another gyro to know heading.  A 150

second flight time doesn't demand a very…

Yet Another Build Log (YABL) - Part 2 - Motor mount LEDs

Since the current ArduPirates code (as you all probably know) supports LEDs not only as a navigation aid, but as a status indicator as well, and since i had nothing better to do while i was waiting for a replacement ESC (one of the four i got turned out to be faulty) i've decided to install them in the jDrones' motor mounts.

Now, i could've just pulled two wires from each motor mount, crimp some female connectors to them and plug them in the OUT4-OUT7 ports, but… Continue
