Led_ring

As Alex has introduced the LED_RING in the new sw, I have purchased this one:
http://www.robotshop.com/dfrobot-rainbow-led-ring.html

Now I have enabled the LED_RING in the sketch, but do not get any output!
Code:
/* I2C DFRobot LED RING communication */
#define LED_RING
So my question: What kind of .pde I need to upload to the LED_RING board? Is it the 'receiver.pde' sketch to get the I2C communication going?
(That is what I did...)

A little lost at the moment...

Not sure if my question was understood: The LED_RING Board has its own Arduino and communicates with the Flyduino (or whatever board you use for your copter) via I2C.
So what kind of sketch I have to upload to the LED_RING Board, to get the communication going? At the moment the LED_RING Board does not do anything - in the LED.PDE from the Wii sw you see that it should work as indicator for the Sensors!

I see you are missing the point.. being lighter doesn't make it safer if you fly it over people and busy roads.. multicopters have lots of stuff that can fail and they don't glide nor auto-rotate. if you hit someone in the head with even say 300g, you'll probably kill the person or animal.. or they can be injured for the rest of their lives..
And I don't think that i'm making a storm in a glass of water here ( sorry, I don't know the right expression)..

Police in the UK was using top technology FPV quads with IR cameras to help them catch criminals successefully, but they had to ground all their fleet because aparentlly they were doing it illegally.. they didn't have licence to fly those machines, so the newspaper said. just google it and you'll find it..

Drone (3 min 1 sec)


Flying my wlan-controlled fpv-drone with firmware-updated escs.. I built the drone over an year ago and posted some pics here a while ago.. now with modified 1.9 and fast escs it is something I wanted.. ;-)

Modified firmware:
Drone with new motor controllers (1 min 38 sec)


Standard firmware:
Drone car(rier) landing (1 min 7 sec)



I try to publish some in-detail information and code of the setup soon..

-Arduino Nano 328, 9 DOF + baro + GPS
-RCTimer 2836/11, 750 kv
-HK Blue 30A, fast firmware
-Flying weight ~2 kg, wingspan 100 cm, motor to motor ~60 cm.
-APC Slow-fly 12 x 3.8 props
-Beagleboard C4 with Ubuntu Linux for control, telemetry datalink, NMEA feed from 10 Hz USB GPS and FPV video link to Sony Glasstron PLM-S700E
-CNC-milled frame, made from polycarbonate and aluminum
-Controlled over wlan using Sony Vaio UX or Nokia N900 ( https://nikita.tnnet.fi/~trosendah/m...e/drone_42.jpg, anytime, ardrone! ;-)

To do: a tracking antenna system with gps bearing and/or signal quality driven control for better range (currently only 300-400 meters which is normal with 802.11n WiFi and omnidirectional antennas) and a long-range 433 MHz / Bluetooth low-bitrate failsafe datalink for long-range GPS-assisted flights..

The only thing safe for an urban environment is if you DON'T fly there. This is a big deal. Not only the weight of the thing, but you are piloting a flying Ginsu machine. With a tricopter there are at least 6 incredibly sharp blades spinning at high RPMs. As jhsa just said there are numerous things that can and will go wrong with a multicopter. It is only a matter of time. Your piloting is not perfect as well. You fly better than me but that isn't saying much. Warthox doesn't even fly around unwilling/unknowing people. Stick to SUBurban and rural areas. Or fly in unpopulated areas near your subject, over water, over trees...

Never fly near busy roads. Just the appearance of a quad over a major road could cause someone to loose concentration, be distracted, and crash. And guess what, you are responsible. That is why in most countries it is illegal to have flashing lights or unapproved signage near the road.

DON'T RUIN IT FOR EVERYONE!!!

YOU CAN NOT MAKE IT SAFE ENOUGH TO FLY IN PUBLIC!!!

he is correct , dont fly in public unless you are allowed to by your administration ( or by the people who allow such stuff ) . a tricopter isnt safe , if you want to fly over people or over water an octocopter is the first choice

Yes,

;-)

Flight times vary between 5-10 minutes, depending on outside temperature. Could be better though.. ;-)
The electronics are powered using a 3 amp switching power supply, backed by BECs, the power consumption is higher than with normal RC-controlled quad but nothing compared to the power draw of the motors =)

The drone hovers at ~50-60 % throttle. It is a little bit overweight, but it does not matter since I don't like to do any aerobatic flying with it. Too expensive.. ;-) I have tuned it to be as stable and steady as possible.

I use 3300-4000 mAh 3-cell Turnigy lipos with the drone. The battery bay is in the CoG, inside the drone. I designed the structure to protect the battery so that it won't get damaged if the drone crashes.
