Peter Homer is a bit of a DIY nut and added a DJI OSMO gimbal 4-axis rig to his list of completed projects.
Check out how you can do it too.
This DIY 4th Axis rig connects to the OSMO and helps eliminate the classic bounce up and down that you get when walking or running. It is cheap and easy to make.
This is the 2nd part of the DJI OSMO Simple DIY 4th Axis Rig. This time I move the mobile device and put a R0DE microphone with the mobile device on the back of the rig.
