Canon DIY External Battery Adapter

It's been a while that I'm developing a camera control board and its software. That takes me hours sending commands for testing it on long shooting sessions. There was no battery enough here for such amount of tests... until now! ;)

Some time ago I've noticed a small hole on the battery slot of my S95. It is protected under a flexible rubber stopper. Well, then I…

GeoTagging Images on Mission Planner


Geo-tagged aerial pictures are very useful for mosaic mapping as well as the creation of accurate 3D models from a terrain.

Michael Oborne added a great tool for injecting GPS data on the EXIF tags by using APM's telemetry log from a flight.

This tutorial was created to show you how does it work.

This is a work from…

Why FRSky CPPM signal is so disappointing. [UPDATED]

[ Update at the end ]

You bought a brand new FRSky with 8 channel and a promise of a helpful PPM Sum output.

Be warned that you cannot use this with 8 channels. Only 6 channels could be used with some risks (only 5 for real safety). [Note #1 at the end] It's really disappointing.

Yes. FRSky's CPPM…

MorpHex - Art, Technology and Innovation

I'm a big fan of Kare Halvorsen's work from biped to multi-pod spiders. His robots are always pretty well tuned to work on his customized RC control with lots of buttons.

This awesome project above is titled MorpHex which is Kare's entry on "BOCA BEARINGS 2012 INNOVATION COMPETITION".

More infos about the competition (and to give him your vote)…

A new "FPV model" by HobbyKing (RQ-4B Global Hawk)

While SkyWalker is out-of stock in almost everywhere, new big size foam models are popping out in many places out there. I just can't stop looking at this one... looks so nice!

The question here is, are those beautiful models really useful for FPV or being our Drones? I would be afraid of breaking such a beautiful thing... and the 2360mm wing…

Aircraft saved by MinimOSD

I just got this video from André Kjellstrup.

It shows the importance of an OSD with instruments in hard FPV flight conditions.

From his own words: "lost visual far out over water when a sudden and passing snow shower with wet, heavy snow clogged lens". Fortunately his craft was equiped with ArduPilot Mega and…

Nice frames: "TwinQuadCopter" and "ButterflyCopter"



There are some nice new approaches on frame construction out there.

This Korean guy found a nice way to get more thrust and it has also a good open space in front.

Looks interesting to fly with cameras. I enjoy the idea. Sounds good. Don't you think?


There is also this other one "ButterflyCopter" with same idea but... 10 motors!!!

Here we can see how nice is the result of a camera…
