Brushless gimbals have been in use for aerial video, but with the shrinking size of quality cinema cameras, many feel this could bring a big change for handheld type shooting. In the last few months there has been an explosion of various brushless gimbal stabilizers, including some affordable DIY options over on eBay. One example is this kit called the HiFly 3 Axis DSLR Brushless Gimbal Camera Stabilizer.
The HiFly is offered in various bundles, but the complete kit comes with everything you need to get flying, but leaves one final step up to the user. The final step required for these type of stabilizers is programming the parameters into the Gimbal controller. There's some additional information on the product listing page on how you can tackle programming the gimbal, but curious if anyone out there is already tackling this type of project? You can see other brushless camera gimbals showing up on eBay (following this link).
