Hi all, I am part of a very small team of folks who are working on moving the 3DR solo IMX6 computers to larger birds. The goal is to leverage the smart shots of solo, with larger camera platforms. In my case a Panasonic GX85 on a custom build. I have a gimbal frame and have started the process of electronics and drive selection.
This will fly on a x8 coaxial bird flying a PH 2.1 Cube and Here GPS. I also plan to make the gimbal compatible to a hand rig so I can run it on and off the bird.
After much research I have pretty much decided to go with Basecam electronics Most likely IFlight Motors I am guessing encoders are really the way to go. So I am looking at one of the extended 32 bit encoder versions with motors that have encoders built in. the frame I have is made for 4108 motors on pitch and roll with a 4006 yaw motor. Which seems odd So most likely I will just go with all 4108 motors
Thanks for that add, and in advance putting up with the many inbound questions I will be documenting this for the Ardupilot wiki pages.
Will post some pictures soon For now any beginner advice would be greatly appreciated
I don't really see a better price there. I can currently purchase a confirmed Basecam extended with encoder firmware, 3 motors with encoders and case for 299. Not to mention that site seems to be ok selling knock offs of the hardware. I prefer the genuine article to support those who are working hard on this system
Just letting you know about better motors for your project! I also sell iflight BGC motor kits & BGC but this type of motors are much better because they are designed for encoders and slip ring, BGC controller for DM40 motor inside the motor . controllers are not knock off there basecamelectronics licence products OEM design boards . I-flight 4108 i do not have good experience with this motor
yes but pm4108 slip ring is little extra cost , DM40 comes with encoder and slip ring all assembled and included & bgc controller with encoder firm wear if needed set of 3 more advanced kit.
so in the end what would a DM40 3 motor bundle with extended controller cost? Interested in going this route thank You! I just have to figure out if the hole pattern will fit my gimbal frame
hmm wait, the 5208 motors are in the 1500 and up weight range My camera with battery and lens comes in at 600 grams 3 X 4108 motors 270 3X 5208 motors 420 So even with the big motors I am just over 1000 grams
Would the 5208 motors be too big for my application? Don't mind that, so long as it can be tuned for the under weight In that case what I need is the extended controller capabilities and 3 motors with encoders What is your recommendation?
Ok sorry Looks like the tiny pro board would offer the same features as the extended. So bundle that with 4108 or DM40 motors it looks like but I am such a noob not sure My best uneducated guess
if your building for copter you need to be able to control the gimbal with RC TxRx all 3 axis and if you are using all 3 encodes you need to use sbus, if your not using all 3 encoders your good with PPM. encoder and RC ports are shared!
I have sbus plan is to use all 3 encoders This project involves using the Solo IMX6 as a companion computer to a Pixhawk 2.1 (cube) In this set up, the flight controller will be sending commands to the gimbal for positioning It is done through mavlink dronekit code on the IMX6
So none of that may actually work, since the gimbal codes was the only piece that 3DR has not opened sourced. Right now many of the guys are just using the solo controller TX for pitch ( the last unsolved puzzle piece to this being able to perform 3dr smart shots completely) current configurations manage everything but pitch and have been ported to generic gimbals
you can also use serial port to control the gimbal much like the storm32 setup with the pixhawk that also an advanced option available if your using all 3 encoders with tiny pro. http://mymobilemms.com/BGC-gimbal-Pixhawk.pdf
controlling only one axis is possible with PPM and 3 encoder !
yes I think that is how it is passing the information looks like the holes I need to deal with on the motor bases is 25mm on the 4108 Still looking at the bell sides and then check the yaw motor which the designer had designated as 4006 motor
yeah that is the conundrum all the holes are 25mm on the frame I think I am going to have to resort to drilling the frame to 30mm on the encoder side and pick a motor with 25mm on the other side
good to know, looks like it will take a while to get here, but if dry fit goes ok, then I will order the other two motors and controller Will link as the source on the build sheet on the wiki
