Making a phototransistor cable for Canon S110
I want to make a phototransistor cable for my S110 to attach infront of its red eye LED light and connecting it to pixhawk in order to imporve the geotagging process. But I am fairly new with electronic, wiring and soldering stuff.Thus I need help and guidance on how to properly make one. I want to know is this the right connection for me to make the cable.Any help is really appreciated. Thank you.Read more…
There is some parameter to tune this value ?
I have a quadcopter with:
2 Lipo 6s ()
4 ESC Monster 2000 ()
4 motors rotomax 80cc ()
But when i arm ans start motors, one motor stop spin when i pull thé throttle to max.
The total weigt of the quad copter is 60kg. The drone dors noté take off even i pull throttle, Elevetor toi max.
What Can tout advice me :
Change ESC to 14S?
Change the 2 Lipo 6s with a 14s battery?
Change propellers with bigger propellers ?
I have question. How can I send pixhawk location to raspi 4. I research this subject on the net and when I see it I have to use dronekit software. Does anyone want to provide additional information?
Note: I will be happy if you would like to share website to search extra
Thanks all of you !!
I have an octocopter with a 20A ESC and a 10000mAh, 10C, 4S multistar battery. The battery I had has been damaged and I can not find a battery with the same (or similar) specifications. I would like to know if it is possible to buy a battery with different specifications, as I understand; the battery I had, provided 10Ah * 10C = 100A / 8 = 12.5A to each servo, which is correct due to the 20A specification from ESC's. So my question is if I could replace the battery with a 5000mAh, 20C and 4S battery?
I hope you can help me, I am new about it.
How to send additional analog sensor information from Arduino to Pixhawk?
What is the best way to do it? Can anyone guide me on how I view sensor data on the mission planner?
I can measure analog sensor data in Arduino now i want to transfer this information to pixhawk.
All the Best
I understand "companion computers" connect to the USB port, the one located below the TELEM2 port
Setting that up involves lots of details about communications protocols.
You can find lots of info about this in the PixHawk documentation available online.
Relaying data to Ground Control Software, you must arrange getting it transmitted via a Telemetry Transmitter (Radio) onboard the craft
to a Telemetry Receiver plugged into the device running the GCS.
My PixHawk starter kit came with 915MHz Telemetry Transmitter (aircraft) and Receiver (ground) radios.
AKA Sik Radios, so named for the Sik firmware they are flashed with.
I'm sure there must be a way to get your sensor data transmitted along with the rest.
You could alternately set up the Arduino with an ESP8266 addon shield, flashed with MAVLink firmware for an extra Telemetry channel on 2.4 GHz (sorta like WiFi)?
And of course make sure your GCS software runs on some device that has WiFi capablility. Perhaps it's running on an Android tablet?
There should be enough keywords in this post to help you search for relevant information. RTFM = Read The Fricken Manual Good luck :)
So to the nub of the issue:
Equipment : Tarot 650 quad copter
Flight controller : Pixhawk 2.4.8
GUI : QGoroudControl version 4.0.5
Motors : EMAX MT 3506 650kv
Props : Various from 10X6 to 12X3.8 CF
ESC: Racer Star 30A BLHeli
Computer : iMac
Tablet for missions : iPad
I have very erratic take off behaviour which I have mostly solved by adjusting the Tuning Parameters in QGC. Once in the air and settled it flies as if on rails. During the flight I occasionally get confusing audio messages from my iPad re possible failure for motor number 4 generally not a problem but on a number of occasions crashes have resulted. Another message tells that the battery voltage is say 10.4V but the iPad shows 12.3V. So I hope that by accessing the telemetry logs I will find information which may solve the problem.
Two types of files show up on my computer, in the Logs folder they are .bin files and in the Telemetry folder .tlog. I have looked at the files using APM Planner. Again searches for programs that can show the telemetry on screen have not helped with Mission Planner the only other program for non professionals. The information in the .tlog files is useless to me and loading the .bin files displays:
Error preparing insertquery: ISBD table ISBD has no column named x Unable to execute statement, which is of no help.
Can anyone list all the data elements in the telemetry file or point me to where I can read about it. Some help with what programs professionals use to analyse the data would also be very helpful as I am not totally computer illiterate.
