Handheld 3-Axis Gimbal For GoPro, Yi, Runcam2 or Rollei410 by willie42 Nov 5, 2017

Summary

Idea and Sources

I made the crossfire2, a 3d-printed quadcopter, which came with a case for the gopro. First I designed a mount for my actioncam, that I owned at that time, the rollei. Then followed a runcam and at last a xiaomi yi.
I redesigned the gimbal to work on three axis instead of two and all worked well.

Than I had the idea, to make a handheld gimbal from those parts and I remembered the rig by Thumber (that I remixed to use it with a smartphone as well).

Components

All I had to do, was design a simple base plate to fit to the rig. I added a motor mount an a plate to carry the controller. There are no dampening balls as there are no propellers running, that cause vibrations. You can use nylon screws to mount the board. I used a self-adhesive velcro pad instead. So I can remove the board when I need access to any of the connectors.
Underneath the plate there is a slot for a velco strip to attach a battery.

I used a STorm32 controller, three 2208 motors and a 2s-lipo. As I added no joystick so I use a Pan-Hod-Pan mode. See the video to understand how it works.

I add a screenshot of the PID-Settings for the run cam as well. See the Storm32 Wiki on how to set those accordingly to improve the performance of your rig.

Parts

The rig and the baseplate are common for all cameras.
The arms and cases are named in a way, that you will know how to combine them.
You will need some 3mm screws a velcro strip for the battery and maybe a velcro pad to fix the controller as well.

Printing

The gimbal_arm0 needs support and the cases do as well.
The baseplate has to be printed without support standing upright.

You will find the FreeCAD-Files of most of the parts in the remixed sources.
