APM 1 and gyro stabilised Photoship One MTR Pro Camera mount

Gyro stabilized mount works quite well. The roll servo does seem to be a bit jerky, but from the forums it seems its one of the downsides to digital servos. What about a small air shock absorber? A trade off of reaction time for fluidity of movement. Although, the platform is for photos not video...

Vision altitude test





A somber ceremony begins, as the machine which caused Major Marcy to sever all contact with us is dismantled & returned to its role as an aircraft position tracker.

The construction of an indoor test harness greatly…

Woody the Quad using APM1 and AC 2.1

Just built a suprisingly good flying quad. Total price with battery but without receiver and APM was $127. It's very usable indoors and later I will add GPS mag, xbee and fpv tilt roll cam today.…

Proof of concept cross-wind navigation (and low level) autopilot with vector field surface tracking

Happy new year!

I've put together a proof of concept autopilot based on the Lyapunov Vector Field path following stuff documented in various UAV research papers of the last many years. It is here:

http://i.dslr.net/vectorfield/autopilot.html

It is written in javascript can can operate in one of two modes. It is only tested on Chrome.

a) it can fly JSBSim,…

Looking back on 2011 - A Review of MyGeekShow

Put together a quick series of my favorite clips of MyGeekShow over this last year, and quickly discussed 2011's goal and how it was acomplished with the Nova.

Was able to go from building simple gliders to building the Nova - an airplane completely designed, built and flown by me, a huge success as I can now create an airplane to specifically meet the needs of any objective.…

From the air.  I hadn't planned on doing this either, but things were so…

Using a DSO Nano oscilloscope to troubleshoot APM

An oscilloscope turned out to be a pretty handy debugging tool when trying to troubleshoot my APM2 ESC problem.  Here's a shakycam showing how I used mine to verify the problem was with the ESC and not with the APM2.

APM2 indoor maiden and simple mode

I got everything together last night and couldn't wait until the morning to go out, so I took a quick flight in the basement.  Stability was pretty good.  I made a quick video of simple mode too.

APM2 ESC startup problem and workaround

Both Andreas and I had the same problem... fortunately he had it before I did, and had figured out a workaround.

Problem: when powering up, not all motors will spin.

Workaround:  apply power to the APM2 before attaching the main battery.  You can do this either via USB or by attaching a spare battery/ESC to one of the output lines.  As soon as the board boots up, hook up the main battery and remove the second battery.…

ArduCopter in action: Testing the QuadCopter (HIL mode) on X-Plane v9

ArduCopter in action: Testing the QuadCopter (HIL mode) on X-Plane v9

Here a video a the ArduMega board (2560 or 1280) with the firmware ArduCopter v2.1.1b (JLN update for X-Plane) connected on the X-Plane simulator throught the APM Planner in HIL mode. The QuadCopter QRO has been modelized for X-Plane v9.0 (or greater) so as get a closest replication of a true QuadCopter UAV.

This is a very good method for testing all the features of the ArduCopter…

MyDIYTri part 4

Ahhh the holidays.

I'd never have the time for an indulgence like this little project any other time of year.

At least not at the rate it's progressing. So far I've managed to get everything that I have assembled into what looks like a nearly complete Tricopter. I really like the double…
