About Me:

I love projects.


Please tell us a bit about your UAV interest

Decided to scratch build a quad with collective pitch. First step was CAD drawings, finished June 2012. The mechanical portion was next and is now complete as of August 2012. Next persuade software to talk collective.

From the WIKI:EKF / DCM Check FailsafeCopter 3.2 adds a DCM heading check and an EKF (Extended Kalman Filter - Pixhawk only) check to catch flyaways caused by a bad heading estimate......I received two errors simultaneously in my log. ERR:…

"Ok, I did connect the radio 5v and GND directly to the 3DR power module then I added a 25v 470uf cap across the power bus of the DTFUHF.
The new traces look much better! New one is on top, old on the bottom.

"I can't explain why those voltage drops seem to last for several seconds. Only thing I can think of at the moment is that the log just happens to be showing a harmonic (logs data at just the right time to land on one of those 25ms pulses low or high…"

"Well there ya have it. It IS the DTFUHF RX. Here is a pic of a three minute log of the Vcc. 
First minute: power on drone, TX off
Second: powered on the TX
Third: removed power from the RX

Now what the heck to I do to stop this. Big Capacitor on…"

Dan Clemens replied to Dan Clemens's discussion Vcc box car effect?
"scope shows a pulse every 25ms, amplitude was .15 v dropped across about one ohm. Duty cycle was close to 50%. Well I think that only amounts to about 0.0225 additional watts. I don't trust my setup that well. No precision dropping resistor and…"

"Had to turn on the TX to get the RX to transmit. Shows 0.069 amps now but that is still only 0.345 watts. Am betting the pulse is pretty short and still may be my power spikes. Scope next."

"I may have found a culprit. The power for my TX is supplied by the APM. What? lil' ole TX? Ya, a DTFUHF one watt TX.....am betting when I get an amp meter on that....well, data to follow.

Well that didn't check out. DTFUHF pulling 0.026…"

"The data source available I found was here:
http://tfr.faa.gov/tfr_map_ims/html/ns/scale3/tile_1_2.html
and looking at Oregon, one lousy spot in the middle of the state. Or so I thought! Upon zooming in on some of the suspect area I noticed on…"

Well today I got the Be-Gez scared out of me. Lifted off my 550 class Alien that is the sum of about two months work and over a $1000 only to lose control a few seconds into my flight. This build has about 10 flights on it. Most worked very well…

"I have seen a few guesses. The main one stated they marked out notams from the FAA. Nope, as of today only about forty notams are listed nationwide and none for the state of Oregon. The polygons seem to be at random in my area. Some make sense,…"

Running an APM mini 3.1 with the stable release 3.2 firmware. I had a series of events leading to this investigation. I performed an auto land with a 550 class drone. 15" CF props and 30a generic SimonK ESC's. The auto land went pretty well and…

"Hey Dave!
I have developed a robot on rails that performs watering and chemical application but have not combined my greenhouse work with drones. Sounds fun! What is the weight of the camera and the duration of a flight?"
