DSLR Gimbal Build

tb1

Hi,

I am planning on building myself a 3axis (or maybe 2axis) gimbal for my DSLR. The total weight of the DSLR and Lens that I will be using is approximately 1600g. I am relatively new to the concept of gimbals, and therefore still have a few questions. I found this wiring diagram (https://i.ytimg.com/vi/rMCQCd6o5JA/maxresdefault.jpg), but I was wondering what the ferrite rings, buzzer and the second IMU sensor were for? Obviously the flight controller and receiver are not relevant for my scenario.

My second question is about the controller. What are the menu buttons for, and what exactly do I need the software for to set up the controller? Also, I want to know what are the general rules to ensure compatibility between the motors and the controller? From my basic electronics knowledge, the voltage output should be matching and the current should be sufficient, however I can't find either of those two specifications on many controllers/motors that I find for sale online! I am currently having a look at these motors with encoders, but I am unsure if the 5208 will be powerful enough:

Would the 6208 be the safer bet, or are the 5208 sufficient?

Finally, I want to make the Gimbal small and portable, in the style of the ikan Beholder DS1. Is there any mechanical details I should note in particular? Obviously the camera should sit in the center and have provisions to be balanced, but is there anything else?

The users manual answers most of your questions. http://www.basecamelectronics.com/files/v3/SimpleBGC_32bit_manual_2_6x_eng.pdf

This might help and give you some ideas for your build http://www.levitezer.com/blog/files/961caec8b987076efd2f7ec37ca6bea0-27.html

Motor size much depends of your need. Stabilisation does not require much power, but fast panning etc. does.

Thanks for the reply. Your videos look great and really explain stuff well!

I am really just looking for stabilization and not so much for panning. So I'm going to assume the 5208 will be sufficient. However, I was wondering if those motors would work with the SimpleBCG tiny controller?

According to the specs, the controller can supply 1A of current. Now, using Ohms law probably completely wrong, this would mean a voltage of 13.6V at an internal resistance of 13.6 Ohm of the motor. However, that is above the output of the board? Does that mean I would have to go for the larger controller?

Also, do encoders make a big difference in terms of how well the gimbal performs? I was trying to find some comparison videos, but couldn't find any.

I think it is pretty correct to use the Ohms law.

If you have weak motors your gimbal must work super smooth and be well balanced. That is always important, but even more so with weak motors.

Howdy, Stranger!
