Getting smooth video from a moving camera is difficult. There is always a new technology coming out to obtain it. In the past, servos have been used, but their gearing and latency can take away from the stabilization. For better results, brushless motors can be used to directly control the gimbal’s moving parts.
Commercial 3-axis gimbals can cost as much as $15,000. However, this two axis camera gimbal design could (in theory) be built for as little as $100. Check out the video after the “read more” to see an animated rendering of it.
This video really showcases the simplicity and ease of use of the design. Directly driving the gimbal minimizes the amount of moving parts and keeps the weight down. This can be useful when carrying the camera mount either by hand or using a UAV.
As for the electronics, one of the benefits of this setup is the simplicity and low cost of the motor controller used. Russel Hay was nice enough to point out the original source of the controller on Twitter.
On the other hand, there are many Chinese knockoffs (such as this one) that can be purchased for a bit cheaper. They include everything you need, including the sensor. This eliminates the need for any low-level design, programming, or even soldering!
Unfortunately, the author of the originally linked article either didn’t finish it, or neglected to post pictures of a finished product. Either way, it shouldn’t be too hard to replicate the process up to the point where the article ends. It would then be up to you to complete this potentially awesome DIY “tripod.”
