Solmeta GPS Tagger

Pretty amazing, a package sent from China via DHL on Monday.

Arrived this morning.

After unpacking and reading the not too good english manual, but much better than most.

I attached it to my Nikon. Simple, straight forward.

Iv attached a couple of geo-tagged images…

Double cascaded RC filters

Spent a lot of time trying to low noise overclock audio preamps.  The main factor affecting you as you get an extremely high gain transducer into subterranian levels of noise is the power supply.  Every consumer gadget encounters some humming noise before it encounters thermal noise.  Even a DSLR has banding…

DIY Drone Summer Camp

We are interested in putting together a technology summer camp for HS (10-12) students where small teams actually build a working drone of some sort using existing designs/components. What low-cost designs would this group suggest? A multicopter would be really cool but I am not sure if we could come up with a truly affordable/survivable solution. Could we build a small AR.Drone sort of craft for $300? Would a rover be best to start with? Has anyone developed any sort of HS curriculum around…

AutoQuad ESC32 v1r5

Recently the Chinese ESC design utilizing the ATMEGA which we have been flashing with Bernard Konze's firmware has been disappearing from the market.  This was the push I needed to finally decide to design and build a replacement.  Collaborating with a friend, we worked on it over the summer.  It is finished and I think it came out pretty well.  I call it ESC32:…

First flight of ArduWot with Simulink in control!

Today we finally got bored of waiting for the windy weather to subside so we took ArduWot out anyway. In the couple of weeks since our last flight we've written an interface between APM and MATLAB/Simulink utilising the MAVLink protocol. For anyone not famliar with Simulink its basically a tool used by control engineers to prototype control systems in a…

FrankenCopter build coming soon! 1 of 1 ;)

Have just finished ordering all the parts I need to build an aerial platform capable of carrying a Nikon D5100 SLR camera.

I have spec'ed up the power for some future heavy lifting projects.

 

The components are as follows:

DIY Drones passes 20,000 members!

As is customary and traditional, we celebrate every new 1,000 members here and share the traffic stats. This time it's a big one: 20,000!

We've been over a million page views a month all year. It just took us six weeks to get this latest 1,000 members--we're averaging about one new member per…

"Fast Transitions of a Quadrocopter Fleet Using Convex Optimization"

More fun from the supercool (and super expensive) motion tracking lab at ETH:

"Fast, safe transitions of multiple quadrocopters are often required in the Flying Machine Arena. In this video, we use an algorithm based on convex optimization to plan collision-free trajectories.



In the first part of the video, the destination points…

Parallax Propeller based quadrotor

Here's a look at the latest iteration of my Parallax Propeller based quadrotor.  The current implementation uses an ITG-3200 3-axis gyro as the only stabilization sensor.

...and an outdoor flight:

Make an optical flow sensor using an Arduino, CdS cells, and a shoebox!

This device is no match for an Randy's sensor, but it does (minimally) work. Think of this little project as a fun hack more than anything else. But with some tweaking and size reduction someone could probably implement an…

This seems very DIYD

Not sure if this is in the military category or not...

WASHINGTON, Dec 05, 2011 The Naval Research Laboratory Vehicle Research Section has successfully completed flight tests for the Autonomous Deployment Demonstration (ADD) program. The final demonstration took place Sept. 1 at the Yuma Proving Grounds, Yuma, Ariz., and consisted of a series of eight…

another way to set modes on turnigy 9x

as it was kind o difficult to me setting up flight modes on APM the way Gordon discribed,  I tried to find an easyer way (but still Gordon did a good job and my way based on his...)

Big THX to apocolipse, as I forgot to write which firmware I`m using. It`s the er9x (lates trunk)

I show on an examples, as it is real easy. What I did is to use the custom switches 1 to 6 (csw1 - csw6) and the mixers.

Goto to mixer and add a line …

Developer
ArduPPM 0.9.87 reports - pushing it to 1.0 release.

I've seen that ArduPPM 0.9.87 has been downloaded about 2 hundred times.

It seems that we have no negative reports with this version.

This is a very good result and does confirm the good results we had at initial testing in the lab and through the development team.

I feel that we could now push this firmware to the realease 1.0 status.

If you have any decoding problems, please report it, so that i can include it as a note in the…

Pushing DJI to limits

Just further pushing what DJI wookong M can do

What I did is removed one motor from standard Jdrones motor with Gaui 500X GM412 and used 11 X 5 Graupner prop. Rest of the threee motors are standard jdrones motors with 10" props.

The only difference was controls became more sensititve. Maybe a PID setting would have helped more. This video was made when the DJI was in Manual…
