Gimbal (AlexMos) Project - WorkLog - DIY

:

Today i ordered the first parts for my Gimbal project.

I have ordered Battery, Motors, and Controller, when i receive the parts i can begin to design the frame.
The Gimbal is going the be used with a Sony A6000 Camera.

This is the fist gimbal i ever made so this is Not a how to guide(at least not yet)
I will keep this article updated with parts, video, drawings as the project moves along.

Turnigy 2200mAh 3S 20C

The motors is rated to 400-900 Grams so i hope they are powerful enough, my camera is 468 grams with the kit lens, so it should Work.

I received the first parts for this build, so now i can begin to make the gimbal. I started to assemble the controller, the pins are not soldered to the print so that had to be done.
You can see on picture below what i had to solder – so if you buy this controller you need som basic soldering skills.

Simblebgs Solder point

I had an old Crius Bluetooth module laying around from a previous quad build, so that is why i soldered the UART pins on the board.
It was pretty easy connecting the Bluetooth module to the controller.

TX – RX
RX – TX
5v – 5v
GND – GND

And from there it was possible to configure the module from the Simplebgc Software.
Bluetooth

After this i connected my phone to the bluetooth module and downloaded the software from Google Play store, and is working perfectly – In the first try – Yayyy.

Simplebgc accelerometer
This is the external Accelerometer – part of the Controller kit, this has to be placed with the camera.

Here the controller is connected to my phone on bluetooth, and its actually more responsive that i thought, and the refresh rate is pretty good to.
I really like the software this controller uses it seems like it is very well made, but of course i haven’t tested it very thoroughly, because i’m still building my gimbal.

At the moment i am designing and drawing, and I haven’t completely decided how I am going to build it. and which materials i’m going to use.
I think the materials will be a mix between carbon tubes and aluminium, but at the moment i do not have access to a CNC milling machine but it would be so awesome to have that.

This is my drawing of the motors i’m using, just to give you a taste of what i am doing.

That is the update for now.
